In 2009, the overall economic situation in China improved, and the commercial vehicle market in China has fully recovered. The production and sales of commercial vehicles have all broken 3 million. Rejoicing, we must clearly understand the gap between domestic commercial vehicle technology and internationally renowned commercial vehicle companies. How to improve the technical level and develop independent brands is an urgent problem to be solved in the future development of commercial vehicle companies in China.
Raising the Technical Level in Three Aspects and Strengthening the Lightweight Development of Automobiles
At present, domestic commercial vehicle technology continues to innovate and develop. In terms of comfort, domestic commercial vehicles pay more attention to humanistic design. Commercial vehicles produced by some manufacturers are comparable to high-end passenger vehicles in their indoor and outdoor driving settings. In terms of safety, the performance of domestic commercial vehicle owners and passive safety systems has reached national standards. In terms of environmental protection, while domestic commercial vehicles increase engine power, various energy conservation and emission reduction levels are also increasing.
However, the process of stepping forward is not all the way. Take the example of improving environmental protection technologies, China's commercial vehicles are seeking development in the game trade-offs. According to Tong Jingen, China National Heavy Duty Truck Chief Economist, the international mainstream commercial vehicle engine emission standards Euro III, Euro IV, and Euro V are proposed by developed countries and are strongly advocated globally. He said that on the one hand, of course, we must unswervingly increase the level of emission reduction; on the other hand, we must not blindly engage in "equipment competitions" with developed countries, consume empty enterprise development potential, and must gradually improve the environmental performance of our products.
In solving the most important propositions of the automotive industry, energy saving and environmental protection, it is not difficult to understand the advantages of lightweighting because it is an effective way to solve this problem. With its light weight, fuel consumption will surely decrease. But many consumers think that if the car is light, is it not safe? In this regard, Zhang Xiaoping, director of the Department of Mechanical and Electrical Engineering of the School of Automobile Engineering at Chang’an University, said: The weight of a car is not necessarily linked to safety. The two are not contradictory. In fact, the safety of cars has different requirements for different parts. For example, there is no buffer on the left and right sides, and it is necessary to improve the safety by hitting rigid bodies such as steel beams. For the front and rear parts of the buffer zone, the energy absorption of the bumper, engine, and trunk is more important.
Lightweight can also bring better control. As the vehicle is light, the acceleration performance at the start is better, and the braking distance at the time of braking is shorter. The fuel consumption of a car mainly depends on the displacement of the engine and the total mass of the car. Under the premise of keeping the overall quality, performance, and cost of the car unchanged or even optimized, reducing the weight of the car can increase output power, reduce noise, improve handling, and reliability. Improve vehicle speed, reduce fuel consumption, reduce exhaust emissions, and increase safety.
The safety of the vehicle is mainly based on the protection of the person when the accident occurs, rather than on the degree of damage to the car. Heavy cars collide with light cars, and heavy cars have less damage, but the degree of damage is closely related to energy-absorbing body design and active and passive safety configurations. Nowadays, many vehicles use sunken engines and so on. In order to crash, the engine will automatically sink and will not cause harm to passengers. Therefore, lightweight technology itself does not contradict security. The truly safe body should be "rigid when rigid, deformed when deformed." Just in reality, it may be that the "lightweightness" of some models is not due to technological advancement, but rather to the so-called jerry-building cuts, which will affect vehicle body safety.
An unpublished survey report completed by the China Association of Automobile Manufacturers in the second half of 2009 shows that there have been lighter weight and fuel consumption tests on hundreds of domestic models. The results show that there is a significant gap between self-owned brands and joint venture brands, European and American brands, and Japanese brands. Everyone says that he is the “fuel economy king†car market. This report gives specific answers and future trends. Lightweight structural design and analysis are currently the fastest growing domestic and foreign lightweight technologies. Car consumers are increasingly demanding vehicle safety. However, the entire society is increasingly calling for environmental protection and energy conservation. Automobile manufacturers have to turn to more solid, lighter materials for vehicle construction. At present, European large-scale automobile manufacturers are carrying out "ultra-light car" projects, and on the basis of stabilizing prices, reducing the weight of cars by 30%. In the design of ultra-lightweight car bodies in Europe, the proportion of high-strength steels exceeds 80%. In the situation where the new energy route is not yet clear, lighter weight has become the global mainstream automobile company and it is in line with the low energy consumption tradeoff line. In this regard, the time left for China is not much.
The arrival of new energy era Commodity vehicle energy-saving technology must speed up
The "Auto Industry Adjustment and Revitalization Plan" has clearly stated that by 2011, the goal of 500,000 production capacity will be formed. In 2009, it may be called China's first year of new energy vehicle development. From Beijing to Tianjin and from Shanghai to Tangshan, new energy auto industry bases have been established in various regions.
Domestic commercial vehicle companies also accelerate the development of new energy vehicles. It is understood that the development path of new energy vehicles of FAW Group will be based on hybrid vehicles, pure electric vehicles, and fuel cells. It plans to build an annual output in 2012. The production base of 11,000 hybrid cars and 1,000 hybrid buses.
"Daikin Dragon" took the development of new energy buses as a bright spot for expanding domestic and overseas markets, and established a multi-sector new energy bus R&D center. In early 2009, after cooperating with Dongfeng Electric Vehicle Co., Ltd. to develop and produce 100 hybrid buses and deliver them to Wuhan Bus Company, in May 2009, it successfully developed a batch of new energy buses to enter Singapore. Achieved the first export of domestic self-owned brand hybrid buses and took Daijinlong's first big step in expanding overseas markets.
From January to November of 2009, the sales volume of LPG passenger cars, LNG buses, and hybrid buses increased by 178.98% to 3,034 vehicles. Compared to the cold ride in the passenger vehicle market, these "new energy vehicles" have begun to grow rapidly in China's commercial vehicle market. In 2010, the country will further promote the development of new energy vehicles. New energy vehicles have risen to the national strategy and have been separated from the limitations of the automotive industry. We have reason to believe that the upcoming new energy automobile industry in 2010 will drive the development of related industries and enter the "fast track" of development.
