Southeast Automotive: Prospects for new technologies for automotive chassis
Gasgoo.com: Please introduce the current status of your company's automotive chassis and engine development. Xie Junlin: South East Motor Company is a joint venture brand. In the automotive chassis, more is the introduction of the main chassis, in the independent brand to borrow the existing chassis-based, in the engine development, because there is no own engine factory, the current engine is mainly Sources are: < P> Mitsubishi imported, Harbin Dongan Mitsubishi Plant, Shenyang Mitsubishi Engine Plant, may use the Liuzhou 474 engine in the microcar. Gasgoo.com: At present, the design and development of the engine and chassis in China draws on the experience of many foreign countries. What do you think about the current status of China's domestic engine and chassis design? How can we achieve the goal of independent research and development? Xie Junlin: Personally think that the current status of domestic engine and chassis design is relatively backward, there are still a considerable part of the engine design surface borrowed from the strength of international design companies, such as AVL, FEV; There is no shortage of design capabilities in the domestic chassis, but there is no relevant experience in tuning and evaluation. Gasgoo.com: At present, the safety and comfort of automobiles are getting more and more attention, such as EPS electronically controlled steering, ESP electronic stability control system, AS active steering, TPMS tire pressure monitoring system and other new technologies. How do you think these technologies are used in the current domestic vehicle chassis? What are the future application prospects? Xie Junlin: EPS electronically assisted steering is a development trend. Due to the implementation of the third phase of China's fuel consumption law, EPS is more promising. After all, he replaced the mechanical power steering mechanism powered by the engine. improve. The current application of TPMS has become more popular and should be promoted. The main function is to detect the tire pressure of four tires. However, please note that the main reason for the puncture is that under the condition of normal tire pressure, due to the damage of the tread, this situation cannot be solved at present. Please pay attention to the industry. ESP is also widely used today and it is necessary. Gasgoo.com: At present, the country has a support policy for halving the purchase tax on small-displacement vehicles, and engine miniaturization has also become a development trend. Your company plans to introduce the two-displacement Lanceros of 1.8 liters and 2.0 liters. What's your opinion on this? Do you think that engine miniaturization represents energy saving and emission reduction? Xie Junlin: National policy in the face of the support of small-displacement vehicles, mainly from the perspective of increasing vehicle production to ensure that China is moving toward a major automobile country, the main support surface for micro-level models and entry-level cars. The miniaturization of the engine does not constitute a development trend. What really sets the trend is the fuel law of the third stage that the country is currently publicizing. I estimate that most of the current domestic engines will not be able to achieve it. The miniaturization of the engine itself is aimed at optimizing the design, which has an improvement effect on energy conservation and emission reduction, but the extent of the solution is limited. If the application is not good, there will be negative results. Lancer Wings is a coupe with a weight of 1400Kg and is a Class B vehicle. It is equivalent to Mondeo, Fox and Mazda 6, etc. Its 1.8L and 2.0L displacement engine is the power that matches it. If it is miniaturized, the old cow will pull the cart.
