With the “Opinions on Encouraging the Development of Energy-saving and Environment-friendly Small-displacement Vehicles†jointly drafted by the six ministries and commissions, the State Council approved that small-displacement vehicles also seem to have reached a point where they can see and see the world.
But think about it carefully, it seems that the state has clearly stated that it is not the first time to encourage the development of small-displacement vehicles: the “Tenth Five-Year Plan†clearly puts emphasis on the development of economical cars; the “Development Policy for the Automobile Industry†promulgated in 2004 clearly expresses encouragement. Development of small displacement cars. However, with regard to the various policies before it, the local government has also introduced many countermeasures, and small-displacement vehicles have still not been able to truly enjoy healthy development.
In fact, it is not difficult to see that all kinds of restrictions on small-displacement vehicles have been found before. Local government restrictions on small-displacement vehicles mainly focus on “impacting city appearance, poor reliability, poor safety, poor discharge, and poor dynamic performance.†aspect. With the emphasis placed on the design of small-displacement vehicles on a global scale, the small-displacement vehicles in the shuttle city have become a beautiful landscape, affecting the appearance of the city, and the remaining points are limited from the technical point of view. The reason for the small displacement car. So, can these points still stand still? Have domestic small-displacement vehicle manufacturers made corresponding technical preparations?
Safety, Emissions: Guaranteed by Certification System
“Actually, there is absolutely no need to question the safety and emissions of small-displacement vehicles.†An automotive expert told reporters: “In terms of safety and emissions, our products are on the market due to the entry system of our automotive products. Previously, it was necessary to pass relevant laws and regulations in order to qualify for listing. In other words, small-displacement vehicle products currently on the market have passed national tests of collision regulations and meet the corresponding national emission regulations.†In fact, not only that In the same way that the emission regulations are met, the small-displacement vehicle will have a significantly lower total amount of pollutants discharged during the driving process than the large-displacement vehicle.
Reliability: Enterprises give full attention
Reliability is a problem that would inevitably be considered when talking about small-displacement vehicles. Due to the low selling price, manufacturers of small-displacement vehicles often have some loopholes in the quality control of their products, resulting in insufficient product reliability. “Buying a car is cheap, but it is afraid of repairing it for three days.†It can be said that the reliability issue is not only an important reason for the relevant departments to be small, but also a direct reason why many consumers say “no†to small-displacement vehicles.
A director of the Geely company responsible for research and development told reporters that Geely attaches great importance to vehicle reliability analysis. At present, Geely has established a product validation system including product testing analysis system, reliability analysis and environmental analysis. Guo Junyi, deputy chief engineer of Hafei Automobile Group, told reporters that Hafei has extensive experience and technical resources in aviation, including strict quality control. In addition, in order to improve the quality of its products, Hafei cooperated with a South Korean company to reconstruct the company's product production processes and achieved good results in quality control. Similarly, during interviews with Chery, Changan, and other manufacturers, the reporters all expressed their concern for product quality and reliability.
Power Performance: Starting from the engine and vehicle matching
The power performance mainly includes the maximum speed and acceleration performance of the vehicle. When it comes to small-displacement vehicles, people are often associated with slow acceleration and low speed. Previously, it was reported that the Development and Reform Commission will issue a standard for economical cars. One of the requirements for the engine is to increase the power to 45 kw/L or more. Although the increase in power does not fully reflect the dynamic performance of the engine, this, after all, indicates that the relevant authorities of the country hope to use this provision to upgrade the technical upgrading of small-displacement vehicles. So, what is the company's preparation for improving the power performance of vehicles?
“The vehicle's dynamic performance is the result of good matching in all aspects. Enhancing the vehicle's dynamic performance is also one of the main directions of our current research and development. I think that for small-displacement vehicles, further improvement of the dynamic performance is completely achievable. On the other hand, by adopting advanced electronic control technologies and other means, we have developed more advanced engines for small-displacement vehicles to improve fuel efficiency; on the other hand, we are still debugging and improving the matching of various parts of vehicles. When driving at speeds above 120 km/h, the impact on power performance is relatively large, so we will take measures to reduce the vehicle's windward area and rolling resistance.†Hua Fulin, the minister of technology at Geely, told reporters.
Independent brands are actively conducting R&D. Many small-displacement vehicles abroad have shown good dynamic performance. Taking Shanghai Volkswagen POLO as an example, a 1.4-liter manual transmission can reach a speed of 170 km/h, while an acceleration time of 0-100 km/h is only 14.8 seconds. Although the POLO still does not meet the requirements of an economical car according to the standards with a power rating greater than or equal to 45kw/L, when reporters interviewed the experts of enterprise technicians and research institutions, the general view was to measure “upgrade power†as a measure. The performance of the power performance indicator is still to be discussed, after all, the vehicle's high-speed driving capability and acceleration performance is the most direct reflection of the vehicle's dynamic performance.
According to the results of interviews with reporters, companies have given sufficient attention to the few technical thresholds for which small-displacement vehicles have encountered restrictions, and have actively conducted corresponding research and development. Compared to whether they can meet the technical standards, they are more concerned with whether the policy can actually be implemented. We hope that this “Limiting the ban on small bans†will not flow into a dead letter. (Reporter Jiang Donglei)
