In the face of the 2020 China's upcoming passenger car average fuel consumption of 5.0 liters / 100 km and energy-saving passenger vehicles 4.5 liters / 100 km below the rigid target, what do domestic car companies to achieve? In addition, in the national strategic plan for new energy vehicles, the cumulative production and sales volume of pure electric vehicles and plug-in hybrid vehicles in 2015 will reach 500,000 vehicles. By 2020, the production capacity of related models will reach 2 million, and the cumulative production and sales volume will exceed 500. 10,000 vehicles, is this plan still possible?
It is possible to achieve these goals through the means of component technology assistance. This is the statement made by the Deputy Secretary-General of the China Association of Automobile Manufacturers Xu Yanhua at the "2014 China Automotive Parts Industry Annual Meeting and China Automotive Parts Development Summit Forum" recently held.
Calculate the average fuel consumption of the company actually realized in each company in 2013 by 7.33 liters/hundred kilometers, and face the country's average annual fuel consumption target (l/100km) achieved from 2015 to 2020 - 2015, 6.9; 2016 Years, 6.7; 2017, 6.4; 2018, 6.0; 2019, 5.5; 2020, 5.0; The annual average drop of 0.38 liters per 100 kilometers is not a small amount. In this regard, Xu Yanhua said that by reducing the driving resistance (oil saving effect 4.0%), achieving efficient combustion (20.6%), improving transmission efficiency (5.2%), reducing auxiliary energy consumption (1.4%), improving energy management (5.7%) In other ways, energy savings of up to 35% can be achieved in a comprehensive manner. This requires improving the thermal efficiency of the engine (direct injection, booster/miniaturization, idle start/stop) and improving the transmission transmission efficiency (a new generation of CVTs without stepping, AT multipoles). (Chemical, dual-clutch DCT) and various comprehensive measures such as lighter weight, lower vehicle wind resistance, and lower tire resistance.
The reporter noted that in the key common topics of energy-saving vehicles provided by China National Automobile Association, the most attention has been paid to the proposal of traditional engine upgrade, advanced start-stop system, hybrid power technology, and advanced diesel technology. In the above four sub-topics, there are many missing technologies in the domestic market, such as in-cylinder turbocharged direct injection and lean, stratified combustion technology, 48-volt start-stop system, hybrid-specific engine, and new diesel high-pressure injection technology. Technology.
In terms of core components, currently included include engine electronic fuel supply systems, engine booster systems, variable valve trains, post-processing and electronic control systems, chain transmission systems, automatic transmissions, high-performance bearings, and power motors. Control systems, exhaust energy recovery systems, and more, there are more parts system technology waiting for the domestic industry to research and development. Of course, the cost of upgrading and installing these systems is also a must for consumers to pay for cleaner, smarter, and safer auto products.
As for key common technical issues of new energy vehicles, Xu Yanhua said that the entire domestic automotive industry is currently in the "five power" -- that is, the power and technical capacity of power batteries, drive motors, electric brakes, electric steering, and electric air conditioning are all in urgent need of improvement. In the future, the country will implement a policy of "reduction and remission" for new energy vehicles and traditional automobiles, committing to a drastic drop in the overall cost of new energy vehicles, to popularizing new energy vehicles as soon as possible, and adding more denominators to the average fuel consumption limit of enterprises. Advantage.
Xu Yanhua pointed out that the parts and components companies, especially the core parts and components enterprises, must through the innovation, scale and other basic elements, through the cooperation of production, education and research, and integrate the resources of the industrial chain, to enhance the quality and management level of related companies. In order to achieve the above energy saving goals, all domestic vehicle and component companies are obliged to shoulder the burden.
