The rise in domestic oil prices not only affects the truck users engaged in cargo transportation, but also makes long-distance passenger transport and urban public transport into the plight of rising costs. Coupled with the increase in people’s awareness of environmental protection, passenger and bus companies have invariably turned their attention to clean energy products – LNG buses.

LNG bus rapid growth
Prior to this, natural gas buses were mainly based on CNG and were subject to shorter cruising range. They were mainly used in taxis and buses. The most obvious advantage of the LNG road passenger car is its long mileage, and its application scope and scale have been further expanded. It is understood that the total number of LNG buses in Zhuhai City reached 858 during the year, which accounted for “half of the total†of the total number of buses; the existing 564 natural gas buses in Ningbo City, Zhejiang Province accounted for 29.3% of the total number of buses in the city; Baoding, Hebei Province also plans to continue at the end of the year. Put 689 LNG buses. In the whole country, the percentage of gas buses in all buses has reached about 20%, especially in some cities in the west and south, and gas buses have become mainstream.
Today, this "LNG fever" also scratches the long-distance passenger transport industry. “The LNG passenger car is equipped with two cylinders that can safely travel for more than 1,000 kilometers. It takes only three to five minutes to add a single gas. LNG has achieved breakthroughs in key technologies for transportation, storage and vehicle use, and it can meet the needs of intercity passenger transport. "Inner Mongolia Tongda Industrial Co., Ltd. Minister of Security Technology Song Baodong said.
The breakthrough in long-distance transportation of LNG buses has led to a gradual increase in demand. It is understood that some passenger transport companies account for 40% of LNG passenger cars, and even some companies set this target at 80%. The market heat has promoted the maturity of the LNG passenger car market. “At present, we are working with PetroChina, Western Gas and other departments to establish negotiations on gas filling stations. Once it is implemented, we will gradually upgrade existing vehicles to LNG gas buses so as to further improve energy-saving and emission reduction.†Huyun Group Relevant person in charge said.
In addition, the support and promotion of government departments is also an inexhaustible motive force for the development of LNG passenger cars. It is understood that the first batch of special energy-saving and emission reduction projects initiated in 2012 is natural gas vehicles, which has increased the enthusiasm of passenger transport companies in applying natural gas vehicles. At present, Shandong Laiwu Freight Group and 8 passenger transport companies in Jiangsu are actively applying for the second batch of support projects in 2012.
The economic benefits and social benefits of LNG bus operations have already begun to show results, and passengers in other regions are actively trying out LNG highway buses. Several companies, such as Shandong Qingdao Jiaoyun Group, Jining Freight Group and Fujian Putian Transportation Co., Ltd., have started LNG bus plans.
Economic advantage is obvious
According to the relevant person in charge of the Guiyang Transportation Bureau, the current “8†oil price is the root cause of their decision to “oil to gasâ€. At present, Guiyang has updated 1,500 buses, which can save fuel costs by about 30 million yuan each year.
“We have used LNG buses for several years and have not encountered any major problems yet. We have also saved fuel expenses. We don’t have to keep smelling gasoline and driving cars.†The Shandong Public Transport Group opened Li’s LNG bus for many years. The master said.
There are not many drivers who share the same feelings with Master Li. Now they have enjoyed the economy and cleanliness of LNG buses. “Compared with fuel vehicles, LNG buses can save about 30% in fuel costs, reduce overall emissions by 40%, and contain no lead, benzene and other carcinogens in the exhaust gas, which is far more economical and environmentally friendly than fuel vehicles. "The strict driver of Beijing LNG bus driver said that the driving environment of LNG vehicles is cleaner and the air in the car has also been significantly improved compared to diesel vehicles.
In addition, Master Liu of Shandong bus driver also calculated accounts for the reporter. “Taking the Jinan-Qingdao line as an example, a total of 730 km round-trip journey takes 168 liters of diesel fuel for ordinary diesel vehicles, and costs about 1,270 yuan; LNG buses consume 160 kg of liquefied natural gas and the expenditure is about 896 yuan. In this way, an LNG vehicle runs In a glance, it will save fuel expenses by 374 yuan and save nearly 30%, which is a very impressive figure.†Master Liu said that although the price of an LNG bus is 80,000 to 100,000 yuan higher than that of a diesel vehicle of the same type, However, in accordance with the operating savings standards, about one year will be able to make up for the increased cost of car purchases.
"As a low-profit industry, passenger transport companies can only work hard to save costs. Before, fuel consumption accounted for a large proportion of the operating costs of passenger transport companies, and LNG passenger cars can greatly reduce fuel costs. Therefore, the use of LNG passenger cars has become a lot of passenger transport enterprises. Uniform choice." Master Liu said.
In October last year, Tongda Passenger Transport purchased a Suzhou Jinlong LNG passenger car fitted with a Yuchai engine. The car mainly ran short-haul passenger transport. “From the viewpoint of operating results, LNG vehicles can save about 1/3 of the cost, and there is no failure during the operation period.†Song Baodong said.
In addition, Song Baodong also believes that because LNG is a clean energy source, the gas can be fully burned and balanced in the engine, which can prolong the service life of the engine. The time for replacing oil and spark plugs can also be extended by at least half, which can also save vehicle maintenance costs. "As ordinary diesel vehicles run between 14,000 and 17,000 kilometers, they need to be maintained. The maintenance mileage of LNG vehicles can reach 60,000 kilometers. In this comparison, the maintenance cost of LNG passenger cars can be saved several times," said Song Baodong.
Gas filling stations become obstacles
According to statistics, there are currently only more than 300 LNG refueling stations in China. The lack of gas stations and complicated construction procedures have become a stumbling block to the development of LNG vehicles.
“Today, although highway mileage is long in most areas in China, there is a serious shortage of gas filling stations covering highway networks.†Tian Weikun, manager of LNG Division of Kunlun Energy Xinjiang Xinjie Co., Ltd., told reporters: “These issues are The existence is mainly due to the supervision of multi-sectors and the slowness of construction approval procedures for the construction of gas filling stations.At present, the establishment of a gas filling station requires the approval of various departments such as land, planning, safety supervision, construction, fire control, and environmental protection. It will take at least one year to wait for the approval of the project. The investment in manpower and material resources will not be a big deal."
In addition, a heavy truck dealer believes that even if the relevant procedures are completed and gas stations are built, there will be cases where inspections cannot be carried out due to lack of relevant standards. “In order not to take responsibility, the relevant management departments will not easily issue relevant standards. Even if the filling stations are built, they will not accept the inspection because the consequences will be very serious once the problem arises,†said the dealer.
The shortage of refueling stations has a great impact on passenger and bus companies, but long-distance passenger transport has a relatively small impact due to a relatively fixed line and enhanced LNG vehicle life. The bus is different. Because of the need to refuel every day, the reliance on filling stations is very strong. This situation has also caused bus drivers to suffer a lot.
“In 2011, we updated some of the LNG buses and conducted trials on the dedicated lines, which worked well. But the only constraint was the shortage of filling stations.†Liu Liao bus driver in Hebei told “Commercial Automotive News†Reporter: “Usually ordinary LNG buses are filled with mobile gas tankers, but gas tankers may not be able to supply gas in time due to time delays or failures. This may cause the entire class to stop operating and can only be transferred to other buses. Operation."
Master Chang Zhang has the same situation. “Our LNG buses rely on gas tankers for refueling, and we often encounter gas shortages.†Master Zhang told reporters: “This situation has recently appeared because gas tankers have failed and cannot get on-site. The LNG buses on the route are not gas-filled, and in order to ensure normal operation, we drove to the far-distance Outer Ring Bus Station after work to refuel at night, because the entire line of cars were concentrated there, causing waiting For too long, the driver’s master complained.â€
Why stop gas tankers in the station? Master Zhang reluctantly stated: “In the beginning, we parked gas tankers on the station. However, due to reports from the public that the refueling vehicles seriously threatened their lives, we can only let gas tankers arrive at the station every day. Later, when we built the gas filling station, nearby residents even reported us to the Public Security Bureau. Finally, after we negotiated with the government, we built the gas filling station.â€
