The General Trend of China's Diesel Engine Market in 2008 The year of 2008 is a special year in the history of China's automotive diesel engine. This year marks the 100th anniversary of the birth of the internal combustion engine industry in China. It is also the 30th anniversary of the reform and opening up, from simple imitation to independent technological development and product manufacturing capabilities, and exports abroad. A relatively complete industrial system has been formed and historic leapfrogging has been completed; this year, the vast majority of vehicle diesel engine models implemented State III emission standards, and China's diesel engines have since entered the era of electronic control; due to financial crisis, etc. The trend of production and sales of automotive diesel engines has come out of an annual curve that has not been met with an ups and downs for many years, and its rate of change is close to 100%. Figure 1 Production and sales volume of diesel engines in recent years (Unit: Taiwan) Figure 2 Annual Production Chart of 2008 Diesel Engine Production (Unit: Taiwan) Figure 3 The year-on-year growth rate of diesel engine production in each month in 2008 (%) At the beginning of the year of 2008, in the off-season, when coupled with the snow and ice disaster in the south, diesel engine manufacturers have achieved very good results. For example, Yuchai's production and sales in January increased by more than 20% year-on-year, setting a record high for the same period. In the first quarter, sales revenue reached nearly 6 billion yuan. In January, Xichai produced and sold 19,000 engines, setting a new high for the company's history in the same period. Dongfeng Cummins produced and sold 15,000 units and 17,000 units respectively in January, an increase of more than 75%. However, by the end of the year, the production and sales of the diesel engine industry in China have become very severe. From a production perspective, in 2008, the year (25 companies) produced a total of 2,333,646 diesel engines, a cumulative decrease of 0.07% from 2007, an increase of 2.34 percentage points lower than the cumulative growth rate of all vehicle engines over the same period. From a sales perspective, a total of 23,96986 diesel engines were sold in the year, a cumulative increase of 3.30% over 2007, which is 1.7 percentage points lower than the cumulative growth rate of sales of all automobile engines. It can be seen that China's automotive diesel engine industry is affected by the economic crisis and other factors deeper than the gasoline engine (Note: In fact, in 2008, the scope of China's diesel engine business was expanded to 25, which is incomparable with previous years' data). From the statistical results, the production and sales ratio of China's diesel engine market in 2008 was very high. In the whole year, only three months of production exceeded the sales volume, and the inventory was small. This is quite different from the situation of supporting complete vehicles, which shows that the diesel engine companies have a more accurate grasp of market conditions, and it also shows that in the industrial chain of the entire commercial vehicle industry, the status of diesel engines as a core assembly resource is very critical. In the statistics, we have found that in the past year, the dieselization of commercial vehicle fuels has maintained a “dominant position.†According to the production statistics, the dieselization rate is more than 78%, and according to sales statistics, the dieselization rate is More than 80%. As fuel prices have increased significantly in the first half of 2008, the proportion of “oil to gas†in various models has increased, but the proportion of gaseous fuel in heavy trucks, semi-trailer tractors and long-distance passenger cars has not been large, because Gas fuel used in commercial vehicles has insurmountable disadvantages: 1. Inconvenient gas filling, natural gas trucks can only run 150 to 250 kilometers each time to fill up, and have high requirements on the density of gas stations, but the reality is that they only exist in the surrounding areas of cities. Gas station. 2. The power of natural gas is poor, and the maximum power of the natural gas engine equipped with the truck models currently sold is generally only below 200kW (only China National Heavy Duty Truck has recently launched more than 240kW natural gas engines). 3, slow speed. Natural gas trucks and buses are all under 80km/h, and the development trend of this model is high speed. 4. The road condition of the truck is poor, and the safety of natural gas tanks still needs improvement.

Its controversy has not stopped since it was adopted by China National Heavy Duty Truck and put it on the market. Now, can EGR technology become the mainstream technology in the transition period of China III? Is the consistency of its production and use reliable? Can it bloom after the country raises its testing standards? These have become the industry's biggest surprises and conjectures. As we all know, the discharge of the National III standard mainly uses high pressure common rail, electronically controlled monomer pump and pump nozzle technology. At present, most engine companies such as Weichai, Shangchai, Yuchai, Chaochai, Cummins, Xichai, and Dichai use high pressure common rail and electronically controlled monomer pump technology. The engine of high pressure common rail is about 10,000 yuan more than that of EGR engine, and the price of electronically controlled unit pump engine is about 7,000 to 8,000 yuan more than that of EGR model. It can be seen that the cost advantage of EGR model is very obvious. At present, some companies are already using the second-generation high pressure common rail products. Delphi and China National Heavy Duty Truck Group, which promotes electronically controlled monomer pumps, have also successfully developed a hybrid electronic control unit pump system. The system is jointly designed by both parties. The pump body is manufactured by China National Heavy Duty Truck and Delphi provides an electronically controlled solenoid valve. Due to the high sulphur content of domestic oil products, it is easy to plug the nozzle opening, which objectively increases the number of maintenance of these two types of technology models. Moreover, this type of model requires high technical level for equipment and operators during maintenance. The core technology of EGR engines is in the hands of Chinese companies themselves, and their production capacity is not limited. It is easy to maintain and has lower requirements for oil products, which is more in line with national conditions. After undergoing the short-term adaptation of the emission standards, the EGR technology of CNHTC's electronically controlled inline pump has taken the lead in the competition with the high pressure common rail and electronic control unit pump technology. However, there is no statistical data on the final comparison of the cost of these two technical routes, whether it is the industry management department or the user. According to reports, related personnel from Yuchai, Weichai, Shangchai, and Xichai revealed that these companies are developing EGR engines, and some have obtained approval from the original Development and Reform Commission. The development cycle of this model is about 20 months, and the models of other companies can be listed in the second half of 2009. According to time projections, the price cuts and promotions of high-pressure common-rail engines were just over. The industry believes that the market is the only factor that determines the existence of technology. Although the relevant national departments require that the new State III products also be tested as durable as the National IV engine to solve the problems of stress, wear, reliability, etc., these companies that subsequently develop EGR are also faced with higher thresholds, but the above new regulations are Can not stop the huge driving force of the market. Although Bosch recently reduced the price of the electronically controlled high pressure common rail system again (the price of each system was reduced by about 5,000 yuan, and the price difference with the EGR model has been reduced to about 4,500 yuan), it is still difficult to reverse the unfavorable situation. Dongfeng Liuqi and Hualing , JAC Geerfa, etc. have switched to heavy-duty truck EGR III engines, and Panzhihuai diesel-powered companies are also expecting mass production of Weichai EGR engines. It can be said whether EGR technology can become a mainstream technology depends not only on whether the electronically controlled high pressure common rail and the electronically controlled monomer pump system can reduce prices, but also on whether EGR can overcome its own shortcomings. Heavy and light diesel engine input more foreign descent In 2008, China's diesel engine market continued to develop for many years and the trend of development was not changed. A total of 582,819 heavy-duty diesel engines were sold (including 106,746 heavy-duty trucks, 239,547 heavy-duty trucks and 36,731 large-sized passenger cars). , equipped with big passenger non-complete vehicles 5733 sets, equipped with semi-trailer tractor 194062 sets), accounting for 27.37% of the total sales of diesel engines. A total of 270,858 medium-sized diesel engines were sold (including 123,523 medium-sized goods vehicles, 76,643 non-integrated Chinese goods, 37,985 medium-duty passenger cars, and 32,707 full-size passenger vehicles). It accounted for 12.72% of the total sales of diesel engines for vehicles. A total of 1,276,140 light diesel engines were sold (including 941,382 light trucks, 97,771 minivans, 95,242 non-integrated light goods vehicles, 14,757 non-integrated micro-vehicles, and 82,201 light passenger vehicles. 44787 sets of light passenger non-complete vehicles were installed, accounting for 59.91% of the total sales of diesel engines for vehicles. From the actual situation of each company, the annual growth rate of the two heavy machinery representative manufacturers of Weichai and Sinotruk reached 22.15% and 17.17%, respectively, 18.8% higher than the average growth rate of the diesel engine industry of 3.30%. 13.87%. Yuchai, which has a relatively large number of light diesel engines, recorded a cumulative growth of 9.13% year-on-year, Shandong Laiyukeng's growth of 35.97%, Anhui Jianghuai's 177.33% and Mianyang Xinhua's year-on-year increase of 311.80%, both exceeding the industry average growth rate. Of course, under this overall trend, the differentiation trend of various diesel engine companies is also very obvious. According to the analysis, the liberated high-powered models in 2008 were equipped with not less than 22,000 units of Weichai engines, and 10 litres of Liberation’s Xichai was liberated. The above diesel engine sales are not satisfactory. Sales of Chaochao, Jiangling, Yangchai, and Nanjing Automobile in the light machine market have also declined significantly. Figure 7 Proportion of Sales of Heavy, Medium and Light Diesel Engines in 2008 Figure 8 Proportion of Production Power of Various Enterprises in 2008 Figure 9 Average change in power per diesel engine in 2008 (unit: kw) It is worth noting that, whether it is heavy-duty diesel engines or light-duty diesel engines, they are undergoing tremendous changes quietly. This change is reflected not only in the introduction and introduction of new technologies, but also in their own brand and international cooperation. In the light engine market, JMC and Chaochao brought in technology from the United States. Nanjing Iveco's production and sales of the Sophim engine have increased rapidly. Dongfeng's light engine production base has been put into production. Among them, Nissan Diesel Engine will surely be in China's light diesel engine. There is a slice of the market. In particular, Fukuda and the United States Cummins to establish a joint venture to produce Cummins ISF series 2.8 liters, 3.8 liters two diesel engines, will enable China's light diesel engine has more foreign ancestry, an essential change. Heavy machinery With the start-up of Xi'an Cummins, the establishment of SAIC Iveco Hongyan and the joint venture between Foton and Mercedes-Benz to produce Mercedes-Benz heavy-duty OM series diesel engines, the competitive landscape of China's heavy-duty diesel engines is bound to change. [next] Production and sales of various models of mainstream diesel engine production enterprises in China FAW Xichai. The sales of the old four-cylinder machine (4110, 4113) and the old six-cylinder machine (6110, etc.) of Xichai in 2008 were not large. The decline of the old four-cylinder machine was close to 30%, but it was the newly launched 4DX and 4DW. The sales of diesel engines of the two types of diesel engines, which were mainly used for low-speed trucks and light trucks after upgrading, have experienced rapid development. After entering the year 2009, the two models of Xichai’s aircraft market are expected to increase steadily from the beginning of the month. The number of over 5,700 units soared to more than 16,000 units. In response to hard-won market demand, the Xichai Production Department started the emergency operation plan, and the new and old assembly lines were produced in three shifts. The daily production capacity has risen to about 950 units. In 2008, the 6113 series in the Xichai six-cylinder machine led the rise, about 80%. In this year, Xichai put into operation a large-displacement CA6DM2 diesel engine, showing that FAW has the determination of owning a heavy-duty diesel engine, but its sales volume of more than 10 liters of heavy-duty engines still needs to be improved. Yuchai. Although it is an independent diesel engine company, Yuchai's heavy medium and light engines have been fully developed. Even if the economic situation is not good, Yuchai has a strong ability to resist risks. In 2008, Yuchai's heavy machine capacity has been greatly improved. At the beginning of the year, it invested 145 million yuan as a heavy machine (YC6M series) cylinder. The foundational phase of the three-phase construction project of the body production line and its strategic cooperation with Dongfeng in heavy machinery have also been strengthened with the increase in sales volume of Tianlong. In terms of light aircraft, Yuchai and Caterpillar, Honeywell and other companies have conducted in-depth cooperation in pressurization, induction control, remanufacturing, logistics, etc., and jointly invested in Zhejiang Geely and Zhejiang Yinlun in March. The foundation of the Jining Yuchai Engine Co., Ltd. was established. After the completion of the project, it will have the capacity to produce 300,000 passenger vehicles diesel engines each year with the Euro V standard. In addition, the Xiamen Yuchai Company, which annually produces 100,000 engines, has also stepped up its construction. Yuchai's North China Agricultural Machinery Production Base, Hubei Yuchai Dooling Engine Co. By the end of 2008, the financial crisis had intensified, and the diesel engine market in China had plummeted. Yuchai’s light machine fell under the influence of the national agricultural machinery subsidy policy, and played a key role in Yuchai’s positive growth during the year. In 2009, the leading technologies applicable to Yuchai's engines include iEGR technology, diesel electronic control technology, Yuchai EIS electronic intelligence system, diesel high pressure injection technology, diesel cleaning technology, VVEB Yuchai cylinder braking technology, and diesel engine structural optimization technology. (Onboard diagnostic system) technology. Key new products in 2009 include: 16-liter YC6T marine diesel engine, YC4FA lightweight vehicle diesel engine, 09th Edition YC6M highway dedicated diesel engine, 09th Edition YC6L vehicle diesel engine, 09th Edition YC6A vehicle diesel engine, 09th Edition YC6J vehicle diesel engine, 09 Version 50 YC6MZ diesel engine for loaders, YC6J125Z diesel engine for 30 loaders, and YC6C diesel engine for large ships. In addition, in 2009, Yuchai will also launch hybrids into the market in small batches. Weichai. After a long period of brewing and actual operations, Weichai has come to an end in the capital market and the development of new models has become a bright spot in 2008. For a long time, the market demand for heavy trucks in China has been very strong. Weichai sold 14,000 units of its 12-liter large-displacement diesel engine WD12 in 2007, an increase of 5 times year-on-year. In 2008, it reached approximately 30,000 units, an increase from the same period last year. 100%. However, Wei Chai early in the year clearly realized that China's heavy truck doubling growth will soon be over. To perfect the product line and achieve diversified development, Weichai has increased the research and development of construction machinery and low-emission engines. In 2008, Weichai formally introduced the WP series of 7-liter and 5-liter diesel engines to the market. In addition to the diversification of power stages, in terms of gaseous fuels, Weichai has established a new joint venture with Canadian Westport Innovation Co., Ltd. and Hong Kong Pei Xin (China) Investment Co., Ltd. to develop and manufacture heavy LNG engines in an attempt to change the power of our country's gaseous fuel engines. Confined to the following medium-sized machines. At present, the newly established company has an annual production capacity of 20,000 units. In 2008, Weichai introduced the National IV and National V models of the WP10 and WP12 platforms. So far, after the Yuchai, Weichai has become the only engine company that possesses the large V diesel engine model. The "common rail line" launched by Weichai using the control function of the electronically controlled high pressure common rail system is a pleasant step in the diesel engine industry to the field of vehicle operation management. The system tracks and controls the vehicles sold by installments to restrict the purchaser’s transaction credit. It can also instantly feedback the vehicle's driving position, reduce the risk of theft, and achieve remote fault diagnosis. It is the only control system that integrates vehicle and engine intelligent management into the market. Dongfeng. The Dongfeng Cummins system's sales momentum in 2008 was very strong. Even under the circumstances of the National III conversion and financial crisis outbreak, its cumulative growth rate was close to 20% year-on-year, which is very rare, indicating Cummins engines in the Chinese market. Won a solid position. In October 2008, Dongfeng Cummins had two major events. First, the annual sales target of over 150,000 units was exceeded in advance. Second, the self-developed China III engine was successfully ignited. This project was considered by Cummins' US headquarters as Cummins' world-first low-cost electronically controlled engine. As of 2008, Dongfeng Cummins has had nearly 10 basic models including B, C, and L series mechanical and ISDe, ISLe, ISZ series fully electronically controlled diesel engines, and B series natural gas engines and hundreds of varieties, with an engine displacement of 3.9 liters. , 4.5 liters, 5.9 liters, 6.7 liters, 8.3 liters, 8.9 liters, 13 liters, power coverage 125-545 horsepower. In 2008, Dongfeng market accounted for 54% and Dongfeng market accounted for 46% in the supporting map of Dongfeng Cummins Engine. At present, an overseas market development alliance that is closely coordinated by engine manufacturers and vehicle manufacturers is being formed. At the end of 2008, Dongfeng Light Engine Co., Ltd. was established as a strategic manufacturing base for Dongfeng Motor Co., Ltd. Dongfeng’s light commercial vehicle engine. It mainly manufactures Nissan and Dongfeng two brands of light engines and assumes the cylinder block and cylinder head. , crankshaft, connecting rod assembly and other test assembly tasks. The main supporting objects are light trucks, SUVs, and light passengers of Dongfeng and Dongfeng limited-day products. The initial production capacity can reach 100,000 units. Dongfeng Company's 4102 and 4100 engines of Chaochai Diesel are the main force of the light truck supporting power. Currently, it has occupied 1/3 of the pure light truck supporting market, and the domestic competition of this power has become a Red Sea. In 2008, Chaochai’s models were flat. It seems that only CYQD32 has become a big bright spot this year, an increase of about 56% year-on-year. However, the Hefei Chaochai plant, which was jointly established with Jianghuai Corporation in 2008, has been officially put into production. Chaochai has signed a letter of intent for joint venture with Navistar of the United States. In the future, Chaochao’s business model and flagship models are quite concerned about the industry. Chaochai's State III model has a great deal of work. Up to now, Chaochai has had more than 50 models of the State III engine and the automobile plant to carry out vehicle calibration together, involving a total of 21 auto factories. Among them, CY4102-C3B, CY4102-C3C and other 20 State III engines have been calibrated for drivability, high temperature, high altitude, and high cold. The remaining more than 30 engines of the State III have been set for some of the above four targets. The company's National III engine has been calibrated at all major domestic automobile plants and passenger car factories. According to statistics, Chaochai has sold a total of 11,000 Taiwan III engines since 2005. With the gradual advancement of the new national emission regulations, Chaochai has made announcements of the State III model in major domestic automobile plants. Until the NDRC issued 171 batches of announcements, Zhachai has passed a total of 851 announcements in all automobile plants, 317 chassis announcements (of which bus chassis announcement 66), basically covering the domestic N2 light trucks and 6 to 8 meters All production companies of passenger cars. China National Heavy Duty Truck. Sinotruck's power systems include the Jinan Engine Division, Hangfa and Chongqing Fuel Injection System Co., Ltd., and Jinan Fuqiang Power Co., Ltd. Judging from the current production capacity, Hangfa accounts for about 65%, and Jinan Engine Department accounts for about 35%. The biggest highlight of the two factories in 2008 was the advent of the EGR engine. Objectively speaking, it is this achievement that triggered the great discussion of the State III technical route, forcing Bosch to drastically adjust the prices of electronically controlled common rails. After the relocation of Hangfa, its production capacity was greatly accelerated. In 2008, two heavy-duty truck companies produced a total of 125,000 engines (vehicles, construction machinery, power generation, and marine use), an increase of 25% year-on-year. After the increase in production capacity, the number of engines supplied by the Group (mainly Hangfa) increased rapidly. According to statistics, 12,000 sets of engines were supplied outside the year, an increase of 102% year-on-year. At the end of 2008, with the completion of China National Heavy Duty Truck's 340-horsepower natural gas engine research and development, it marked that CNHTC's natural gas engine spectrum has been improved. The WT615 series of natural gas engine products have covered power segments from 230 horsepower to 340 horsepower. The available fuels are compressed natural gas (CNG) and liquefied natural gas (LNG). At the end of 2007, the WT615 series of natural gas engines with power levels below 300 horsepower was formally put into the market. At the end of 2008, China National Heavy Duty Truck launched a natural gas engine with more than 300 horsepower, which further improved the spectrum of China National Heavy Duty Truck natural gas engines. The 340-horsepower natural gas engine is the most powerful engine in domestic natural gas engines. Even so, the main problem facing CNHTC Group at present is that there are few aircrafts (basically only the WD615 series). In the situation of heavy-duty trucks being pulled back in 2009, CNHTC's engine production will face a severe test. Deutz FAW (Dalian) Diesel Engine Company. Dachai products are currently mainly C series (CA4DC), E series (CA6DE2, CA6DE3), F series (CA4DF, CA6DF, CA6DFL) and DEUTZ series. In the face of the special situation of the Chinese diesel engine market in 2008, Dachai has taken advantage of the promotion and service of Deutz products to help Dachai to better capture the domestic market. In terms of services, Daichai promised to purchase users of Liberation Dewey Deutz cars from March 1, 2008. The Deutz engine with traction, cargo, and van matching will be used for 12 months and 10 months. Thousands of kilometers; within 45 days of buying a car, due to quality problems, it is necessary to replace the cylinder, cylinder head, crankshaft, and replace the engine assembly. At present, Dachao Daoyes Diesel Engine is selected by FAW Dako, Huanghai and other passenger vehicle factories for supporting passenger cars, and passenger buses run on passenger cars in cities such as Dalian, Fuzhou, Changchun, Shanghai, Wuhan, Shenyang and Guiyang. During the Olympic Games, the hybrid passenger car equipped with this model was running smoothly on the roads in the Beijing area, and energy conservation was significant, which was highly concerned by the industry. Yangchai. In 2008, Yangchai sold more than 100,000 diesel engines (including 82,000 vehicles), and the 485 series produced 26,000 units, an increase of up to 130%. The annual output of the company's diesel engine exceeded the 100,000 mark for the first time. In 2008, Yangchai made every effort to develop all types of aircraft that meet the national III emission standards, and successively completed the national III research and development of the YZ4DA, B, C, D, E full range of products, and steadily entered the batch production support. While developing the products of State III, Yangchai announced more than 700 new country III announcements throughout the year, providing a strong guarantee for the follow-up sales of products. In the process of product development, Yangchai insisted on independently developing and utilizing the “outside of the brain†to collaborate with Jiangsu University, Yangzhou University and other universities to cooperate in the production, research and research projects, which provided theoretical guidance for solving practical product problems and optimizing product structure design. In addition, Yangchai actively develops new customers, especially the overseas market, and has made breakthrough progress. On the basis of self-operated exports in 2007, nearly 17,600 diesel engines were exported in 2008, which became a bright spot for product sales. [next] Fuel Tax Makes New Type of Achievement in Fuel Saving for Various Types of Diesel Engines The fuel tax has been warmed up for many years in China. It is this long-term warming that has caused the taxation to have a lasting impact on the impact of China's diesel industry, especially on the research and progress of fuel-efficient technologies. At the end of 2007, the implementation of the fuel tax finally came to an end. Every company's diesel engine fuel economy research has spared no effort. The new fuel saving technologies introduced by each company are worthy of a special book in 2008. The gas-fueled engines of Yuchai, Shangchai, Xichai, Dichai, and Weichai basically cover more than 70% of all models. For example, the CA6SL1-26E4 and CA6SF2-NE4 natural gas engines launched by Xichai have reached the national IV emission standards. The lean burn and advanced angle control reduce the thermal load and increase the knock margin, which greatly saves fuel. Its CA4DL1-20E3 model is a national diesel engine with a large domestic power. It adopts precise pre-injection design and secondary balance mechanism to reduce noise and save diesel. In 2008, Yuchai held a number of gas fuel engine customer exchange meetings. With advanced electronically controlled combustion and management methods, Yuchai's gas fuelled engines have occupied 50% of the market share in many cities. In the 09 engine jointly developed by Weichai and Bosch and equipped with Auman, a core technology is to use multi-state fuel-saving switch, so that the engine power is adjustable, the user can select the engine according to the actual loading conditions and running road conditions The power output, in order to reduce the extra power consumption, achieves an engine to achieve the efficacy of several engines. Also relying on the advanced platform of the electronically controlled high pressure common rail system, Weichai Power has developed an oil-saving constant temperature fan and an oil-saving and broken-cylinder technology. The combined use of the two technologies can reduce the fuel consumption of the vehicle by 8% to 15%. Xi'an Cummins will start production of a new generation of ISM11 full-controlled heavy-duty diesel engine that meets the national IV emission standard. It adopts the SCR selective catalytic reduction aftertreatment system, which is 5% more than the previous generation III engine and is expected to be put into production in 2009. . The DK4A diesel engine of the Golden Cup Garrison diesel version uses an upright DOHC4 valve structure and a central injector, which is lowered by means of erecting the injector at the center of the cylinder bore, improving the shape of the combustion chamber, and using two different shapes of independent holes. Eddy current deviation increases fuel spray distribution and air utilization, which in turn dramatically increases engine maximum power and maximum torque. With 2.5L displacement, the maximum power will reach 75kW, and the maximum torque will reach 260NM. The diesel engine for cars is getting further and further The dieselization of sedans was the prediction of many experts, and it is also one of the projects that Bosch and other multinational companies have pushed for in the Chinese market. Indeed, diesel engines have long life, low wear, and high fuel efficiency. Diesel passenger cars in many European countries once reached 50% of the total new vehicle consumption. China FAW-Volkswagen has been producing diesel cars by assembly. Yuchai, Chery, Geely, Yunnei and other diesel companies have invested heavily in diesel cars, but the market for diesel cars has not been able to open. In general, diesel engines are 20% to 25% less fuel-efficient than gasoline engines, but because Chinese cars rarely run uninterrupted over long distances like Europe and the United States, it is estimated that it takes four years for diesel cars to be able to The difference in the price of the gasoline engine (taken from the gasoline price difference at the beginning of 2008 as an example) earned it. In the global economic downturn and the sharp drop in oil prices, the outlook for diesel engines is even less optimistic. On May 21, 2008, the price of diesel in Germany was the same as that of gasoline for the first time, both at 1.52 euros per liter. Therefore, it lost its long-term advantage of low cost, and then took into account the traditional technical advantages of diesel engines over gasoline engines. The latter targeted targeted technological innovation (for example, Mercedes-Benz is developing a more efficient "compression-ignition" gasoline engine) will disappear, experts predict that a successful history of diesel cars favored, will Become the past. Many people hold this view in Belgium and Italy. The consensus view of experts is that the expansion of diesel cars has reached its peak, and in the next few years, petrol cars will regain some market share. In China, where car diesel engines have not been developed, their prospects are even less optimistic. On the contrary, the prospect of hybrid power will be more clear. Figure 10 The sales of FAW Volkswagen sedan diesel engine in 2008 (Unit: Taiwan) Engine Market Forecast in 2009 In order to stimulate the Chinese economy in 2009, the Central Government and local governments have introduced supporting facilities. In the trillions of bailout plans, only a few hundred billion yuan are currently invested. It is expected that about 2 trillion yuan will be put into place by the end of February. It is expected that the amount of infrastructure projects in China will be large in 2009, and diesel engines will still have a certain market demand. From the situation of Xichai, Yuchai, Laidong and Jianghuai, the relevant policies to stimulate agricultural machinery have taken initial effect. From the statistics of auto vehicles, even in the most difficult period after September 2008, the sales volume of trucks with a mass of less than 1.8 tons is also higher than 15%. Therefore, light diesel engines may be the first to get out of winter. For the heavy machine market, it is analyzed that the heavy truck industry will resume its upward trend in the second half of 2009. It is expected that the demand for heavy trucks will fall slightly by 5% in 2009, but the demand growth rate in the second half of 2009 and 2010 will be 15 %the above. Taking into account comprehensively, the total market demand for diesel engines in 2009 may be about the same as in 2008, with about 333 to 340,000 units.
