On March 1 this year, Beijing took the lead in implementing the National IV emission standards for vehicle exhaust gases. This is a substantial action taken by the Chinese government in reducing exhaust emissions and improving environmental quality. Beijing implemented the national IV emission standard in advance and reduced the time gap between the original implementation of the European emission standards from ten years to about three years. This proves that the technical level of China’s automobile engines has been substantially improved, and the overall strength of the domestic engine companies has been achieved. Has been greatly improved.
Different from the past, this time, Beijing implemented the national IV emission standard, and the self-owned brand automobile companies did not appear to have affected their car sales in the Beijing market because they did not meet the new emission standards. The increase in costs caused by the upgrading of engine technology has not been passed on to consumers. This shows that automakers of their own brands are fully prepared to deal with the increasingly stringent emission standards.
Although the self-owned brand engine won the first round in the fierce market competition, compared with the advanced level in foreign countries, the gap is still very large. The capacity for independent development is weak and the capacity for innovation is insufficient. High-tech still relies on foreign countries, and products with international competitiveness are insufficient. These have become the weaknesses of domestic engine companies.
For engine parts, the problem may be more serious. In previous years, the main energy of domestic auto companies was focused on vehicle development and manufacturing. There was no attention or even neglected the development and manufacture of components including the engine. This resulted in the lack of key components and technologies for domestic engines. For example, the key parts technology and system integration technologies such as engine management systems that have a significant influence on engine performance and cost are still in the hands of several foreign giants; turbochargers, hydraulic tappets, variable valves, and variable valve lifts. Advanced components and other components are also basically dependent on foreign imports or their domestic production facilities.
Commercial vehicle diesel engines are the areas with the highest level of independent research and development and the highest share of self-owned brands in China's automobile engine industry. Major domestic diesel engine companies such as Yuchai, Weichai, Shangchai, Xichai, Chaochai, and Yunnei have completed their national III technology upgrades for their diesel engine products, and some companies have developed in advance to meet the national IV emission standards. Diesel engines are also ready to implement more stringent emission standards.
Baidu (baidu.com) electronically controlled common rail diesel injection, electronically controlled pump nozzles, multi-valve, turbo-cooled intercooling, exhaust gas purification technology, combustion process control and other mainstream technologies have been mastered by major domestic commercial vehicle diesel engine companies. . While accelerating the technological upgrading, domestic commercial vehicle diesel engine enterprises also actively strengthened the development of joint ventures and cooperation with foreign diesel engine companies and improved the technological level of the products. If Chaochao introduced U.S. U.S. NGD 3.0 diesel engines, Dichai and Deutz of Germany jointly produce German Deutz 4.0 to 7.2 litre diesel engines, but large-displacement high-performance commercial vehicle diesels of over 10 liters are still foreign companies. The world.
Fortunately, after fierce market competition in recent years, companies with independent brand engines have basically stood firm and won the opportunity to continue to compete with international automobile giants on the same stage. Related companies and government agencies have begun to pay attention to key zeros. The development of components. In terms of parts manufacturing and system integration including engine management systems, some domestic companies have made breakthroughs. Only by mastering the technology of key components, the gap between the overall technical level of domestic engines and the advanced level of foreign countries can be reduced. It is possible for China to produce an internationally competitive engine product, and it is possible to become a truly powerful engine manufacturer. .
