In the interview, the reporter learned that the diesel engine market in China had peaked in 2007, and the annual sales volume reached more than 2 million units. Among them, the rapid development of the light truck market, as well as the development of short-distance transportation and the rural automobile market, have brought tremendous development opportunities to the light engine industry. Although the growth rate of production and sales at that time was rapid, the problem of lagging technology and excessively rough manufacturing processes of China's light diesel engines has not been effectively improved. With the ever-increasing stringency of emission regulations, enterprises are trying to change the status quo, but suffer from existing problems. Difficulties in product platform upgrades have made the challenges faced by light diesel engines increasingly severe. Industry experts believe that compared with foreign diesel engine oil, China's light diesel engine technology is relatively backward. Faced with the problem of survival, enterprises must guard against arrogance and prudence, improve their technology in a down-to-earth manner, or they will suffer catastrophe in the severe test. Â 
An engineer from Changchai Co., Ltd. said that the upgrade of low-end light diesel engines is very difficult. For diesel engines, the entire emissions system needs to be updated. The second country to upgrade the country three, due to lack of market monitoring, many companies have played a "trimming the ball," did not really bother to do technical upgrading, the product can barely be able to upgrade the three national standards, but to upgrade the national standard, the backward platform must be updated. Such as high pressure common rail technology, post-processing technology. In addition to product upgrade difficulties, the reporter found that in the light truck market, many decks of light diesel engines are more difficult to solve. Although the National IV standard has been implemented, there are still many standard-two machines on the market, and there are many deck products. Under this circumstance, enterprises face the challenges of the country, and need to invest a lot of R&D funds, which takes a relatively long period of research and development. Otherwise, in the fierce market competition and the continuous pressure from OEMs to lower prices, companies can only maintain low profits. In the long run, companies may die in this smoke-free war.
An engine company's sales staff said that the obstacles to the development of the enterprise are also core technology patent issues. Every 3 to 5 years, foreign-funded enterprises will open up their patents for technology research and development, and domestic companies will conduct imitation studies. However, in the process, foreign companies will increase investment in research and development of new technologies, carry out new vehicle loading, product verification, and market launches. New products will always occupy a leading market share. This is a vicious cycle, and domestic enterprises will always be in a backward and backward position. In the end, the strength of the company lies in R&D rather than imitation.
The phenomenon of the light engine market reflects the contradiction between China's economic development and inertial thinking. While China's development has taken over the world, it also shoulders certain responsibilities. Industry experts believe that compared with the technology of foreign engines, the independent brand manufacturing process is not up to standard, the low-end raw materials, and the purchase of expired engine platforms for domestic production have resulted in engine technology lagging behind for 20 to 30 years. In the process of cooperating with foreign companies, they exposed the problem of savoring nothing, only superficially learned design ideas and parameters, and mastered only the imitation ability of high-end technology rather than the overall manufacturing capability.
The person in charge of Quanchai stated that the government has been swaying for years and years, policies have failed to spread in time, enforcement power and supervision are not in place, resulting in the lack of credibility, and the company’s sociality is not high, it is simply pursuing profits, with a sense of fortune, it is responsible to society. not enough. The government should increase publicity to raise awareness of environmental protection among enterprises and consumers. The pressure of environmental protection can not only allow users to bear the burden, but also give partial subsidies to users, and should increase investment in environmental protection industries.
Xin Jianhua, head of the propaganda department of Dongfeng Chaoyang Chaochai Power Co., Ltd., believes that the state should implement a new emission standard and plan ahead to make arrangements for it to give sufficient preparation time to ensure a smooth and orderly market switch. The twists and turns of the country’s four policies have undermined the credibility of the government, allowing companies to slack off, and suddenly implemented them strictly. Companies are caught off guard. In addition, oil products have a great influence on the overall performance and emissions of the engine, and it is hoped that the problems of the four supporting facilities in the country will be solved as soon as possible. In the face of environmental issues, the government must rely on coercive measures to help transform the industry.
