Diesel passenger vehicles are rare in China, and there are only about 100,000 vehicles. Compared with the number of passenger vehicles in China that have more than 11 million vehicles, they only account for 1%, which is a kind of better than nothing. In Europe, the diesel passenger car has already accounted for 50%. The dieselization of passenger cars has become a big deal.
Compared with the gasoline engine, the development of small diesel engine technology not only consolidates the traditional advantages of fuel economy, but also overcomes the disadvantages of large vibration, high noise, and high emission, and becomes comparable to gasoline engines. It is precisely because the combined performance of small diesel engines exceeds that of gasoline engines that diesel passenger cars have become a trend of development and have occupied half of the country in Europe. In China, the promotion of diesel passenger vehicles has been difficult. The reason is not limited to one end.
â– Small diesel engines are superior to petrol engines The biggest advantages of diesel engines are the power and torque. Passenger cars equipped with diesel engines can generally save more than 30% of their fuel consumption per 100 kilometers compared with gasoline vehicles of the same model. 30% of the world is not a small number. The earth, which is increasingly in short supply of oil resources, is certainly a great advantage for China whose foreign oil dependence has reached 53%. For this reason alone, the dieselization of passenger cars is worth trying.
The diesel cars left a bad impression on the Chinese people. Diesel engines are generally installed on heavy trucks, construction machinery and ships in China. In the past, the discharge standards were not strictly related to the heavy diesel engines installed on these transportation or engineering tools. The development of small diesel engines for passenger cars has overcome technical problems such as noise, vibration, and emissions, and has even surpassed gasoline engines in some indicators. For example, in terms of carbon dioxide emissions, small diesel engines emit only 20% to 30% of gasoline engines.
It is the advancements in the technology of small diesel engines that have made dieselization of passenger cars a good thing to do. In this regard, Europe has taken the lead. In recent years, China has made great strides in small diesel engine technology. According to Wei Anli, deputy secretary-general of the China Internal Combustion Engine Industry Association, Yunnei and Yuchai have their own research and development diesel engine for passenger vehicles; Yangchai, Euro-Yide, and Jiangling have also mastered the technology of purchasing Italian VM companies. The technology for manufacturing diesel engines for passenger cars is also available; Great Wall, JAC and two automobile companies can independently manufacture passenger car diesel engines.
Yang Yongzhong, general manager of Yunnei Power Co., Ltd., said that China's small diesel engine technology does not lag behind those of Europe and the United States. The performance of small diesel engines manufactured by China is not much different from that of well-known European and American manufacturers.
It seems that the technical conditions for promoting the dieselization of passenger vehicles in China have matured, and the insufficiency of taking the Chinese passenger vehicles into dieselization is not a technical factor.
â– Difficulties in the dieselization of passenger vehicles There are many factors that restrict the dieselization of passenger cars in China. Wei Anli has long paid attention to the dieselization of passenger cars and promoted the promotion of diesel cars. In his view, in addition to the aforementioned consumer's negative impression on small diesel engines, there are four reasons that restrict the large-scale dieselization of cars.
First, the internal combustion engine produced by the main engine plant is mostly a gasoline engine, which makes auto companies unwilling to promote the dieselization of passenger vehicles because of their behavioral inertia and maintenance of their own interests.
Second, joint ventures are subject to the restriction that foreign parties cannot make favorable choices for the Chinese society. The main force of Chinese passenger vehicle companies is joint ventures. Foreign partners of joint ventures generally only care about making more money. They are not interested in the long-term development of China. The promotion of diesel passenger vehicles is time-consuming and laborious, and the market acceptance at the start is doubtful. Foreigners do not want to spend much effort.
Among the joint ventures, European and American companies accounted for a considerable part of the vehicles sold to European and American markets by more than half are diesel vehicles, but there is no diesel vehicle except for a Jetta in the Chinese market. In addition to the unwillingness to spend extra efforts, the main reason is that the foreign partners of the joint venture company are fully aware that the diesel passenger vehicle represents the direction of the development of the passenger vehicle power in the next 30 years. They hope to permanently occupy the technical commanding height of the diesel passenger vehicle and are reluctant to see China. The smaller diesel engines achieved greater technological advancement due to dieselization.
More importantly, the small diesel engine is more advanced than the gasoline engine. If the large-scale promotion is bound to receive huge economic and social benefits, the western political and economic forces behind the joint venture's foreign parties do not want China to promote small-scale diesel engines for the sake of curbing the development of China.
Third, the fuel injection system has limited the promotion of diesel passenger vehicles. China's fuel injection system has previously set gasoline for passenger vehicles and diesel for commercial vehicles and construction machinery. Therefore, in the central area of ​​many cities, there are a total of 10 refueling guns for 5 refuelling stations in gas stations that can only be filled with gasoline, and there are diesel refueling machines at the edge of the city. For example, in Beijing, because of the inability to allow commercial vehicles such as heavy trucks to enter the urban area, there are few gas stations that can fill diesel fuel in the Fourth Ring Road. Many auto companies, including some independent brands, believe that if they can't refuel, then making a car can't be sold. It's better not to make it. The supplier of refined oil thinks that since there is no diesel passenger car, why should it provide diesel in the urban area? So he fell into the vicious circle of "since there was no car, why oil is needed" and "since there was no oil, why build a car?"
Fourth, the benefits of fuel economy cannot offset the gap in car prices. At present, the production scale of small diesel engines is much smaller than that of gasoline engines, and the process precision is higher than that of gasoline engines, which causes the cost of producing small diesel engines to be higher than that of gasoline engines. In response, Wei Anli said with a smile: "China's oil price is not high enough. If it is higher, the temptation to save 30% of oil will enable a large number of consumers to switch to diesel vehicles." Mr. Li Chunpei, general manager of Euro-Italy believes that Chinese consumers The consumer psychology is more focused on the benefits that can be realized immediately, and is more concerned with the number of lump sum payments, and is relatively weak on the amount of money that can be saved by saving fuel in the future.
Yang Yongzhong also believes that the previous diesel shortage is one of the reasons restricting the dieselization of passenger cars. He said that the problem can be effectively solved after the refined oil is allowed to be supplied through imports.
