According to relevant regulations, China has fully implemented the country's 3 emission standards this year. In terms of new products, the country's 3 standard models are the products that the diesel engine companies have struggled with in 2007. After preparations in recent years, the 3 diesel engines of major diesel engine companies such as Yuchai, Weichai, Xichai, Dichai, Chaochai, and Dongfeng Cummins have been serialized, and the state-of-the-art 3 technology has transitioned from a conceptualized and trial-type to a practical stage.
Heavy-duty diesel engines are not a big problem in responding to the country's 3 emission standards. It is worth noting that some small and medium-sized diesel engine-based engine companies have also started to use state-standard diesel engines last year, indicating that these companies are not only targeting their own models at light trucks and light weight. In addition to passengers, it has also made technical reserves for future diesel engine upgrade emission standards, which is another breakthrough for the group's diesel engine enterprises after transitioning to multi-cylinder engines. The extension of the 3rd standard diesel engine to the small diesel engine area will make the cost predicament in this area that is already high.
Yangchai cooperated with AVL to jointly develop the National 3 standard diesel engine. At present, Yangchai has successfully developed the YZ4DB1-30 and YZ4DA1-30 engines using the electronically controlled monomer pump technology, which is determined through the National 3 product system. This two-country 3 diesel engine has successfully entered the passenger car market. Quanchai has always been a supplier to Beijing Foton, FAW Hongta, and JAC. In order to further speed up product upgrading in 2007, Quanchai cooperated with Bosch in Germany and Shanghai Internal Combustion Engine Research Institute to successfully develop 4D22E, 4D37E, and 3 series of small-bore vehicles. With a diesel engine, a wide range of supporting light trucks. Changchai's 300,000 multi-cylinder machine base (phase 1) project was put into production on December 28, 2007. The main producing countries were 3 and 4 multi-cylinder diesel engines.
The first phase of the project will have a total investment of 160 million yuan. After the project is completed, it will fully upgrade the product quality of the multi-cylinder machine. The 4B28TC common-rail diesel engine being ignited is based on the technical evaluation of Austrian AVL company and completed using the common rail system of Bosch. of.
Light commercial vehicles are the most difficult sector to implement the country's 3 standard. According to Ni Hongjie, chairman of China National Internal Combustion Engine Industry Association, there are two major problems in the implementation of country 3, one is the oil problem, many small and medium-sized cities are difficult to supply oil, China's national standard diesel engine using standard diesel fuel The emission standards are lower than those of the country 3, but higher than the country 2, and have a certain degree of impact on the life of engine components. The other is the cost issue. In terms of electronic injection systems, the cost of both the common-rail system and the single-unit pump system will increase a lot. This is acceptable for heavy-duty vehicles, but for light-duty vehicles, the engine plant If common rail systems are to be used, the current price of a common rail system at Bosch is between 6,000 and 8,000 yuan. How much is the cost of a four-cylinder light-vehicle engine, that is, 6,000 yuan, and some are even lower? For four or five thousand yuan, if the common-rail system is used, the cost of the engine will have to be doubled. The automobile factory cannot accept it because a light-duty vehicle will be sold for three to four thousand yuan in the market.
Of course, the common rail system developed by domestic manufacturers has also come out, but no batches have yet been formed. In addition, domestic manufacturers use lower-cost fuel injection programs are also under development. Overall, although there are still several months away from the implementation of the National 3 emission standards for light vehicles, the difficult situation created by cost factors cannot be fundamentally alleviated.
