On May 21, 2009, the second China Green Transportation International Summit 2009 was held in Changfugong, Beijing. More than 100 participants including government officials, Chinese and foreign technical experts, auto companies, China Bus Network, and China Truck Network media representatives participated in the event. With this international-level seminar, Bosch, as a pioneer and leader in modern diesel technology, was invited to the conference. During the coffee break, Mr. Stefan Frantz, Marketing Director of Bosch Automotive Diesel Systems Co., Ltd., was invited by China Bus Network and China Truck Network to introduce Bosch's commitment to the development of clean diesel technology yesterday, today and tomorrow. In the past 10 years, the proportion and application level of diesel engines used in passenger cars and trucks in China have developed rapidly. The Chinese government has controlled the environmental protection of motor vehicles in the shortest 10 years and has passed the European automotive industry for nearly 20 years. Mr. Stefan Frantz said: "China's emissions regulations continue to rigorously promote the development of diesel technology. This is the government's requirements for the automotive industry. It also requires that automobile-related companies develop and provide corresponding products and technologies to meet regulatory requirements. , As a supplier of fuel injection technology, we provide customers with advanced diesel technology according to market requirements, and support customers to develop a new generation of clean diesel engines. Bosch's common rail system can cover and match almost all automotive and engineering diesel engines, so customers The most suitable common rail system can be selected.†It can be seen that Bosch has rich experience in reducing emissions, optimizing performance and improving economic efficiency of diesel engines, and has played an important and positive role in the improvement of the technical level of Chinese diesel engines. In the past year, discussions about "EGR" and "common rail" were even called "controversy," but Mr. Stefan Frantz said: "I don't call this argument, EGR and common rails are just Different solutions on the market: In some areas, customers choose EGR, while others still respect and use common rail systems. Customers choose common rail because common rails have their own advantages: Existing engines have a common rail system installed. The flexibility in engine matching is very strong, easy to achieve emissions, performance and driving characteristics. In addition, the mature common rail system has very good reliability. Forum is discussing more stringent emission standards, such as European V Euro VI emission standards There are also countries V and VI. It is understood that the common rail system can fully meet all current emission standards. “According to the official disclosure of the Chinese government, China will introduce the national IV standard next year,†said Mr. Stefan Frantz. “In terms of technology and products, Bosch is fully prepared. Its injection system is still a common rail system, only in certain Under this circumstance, it is necessary to make some improvements on the basis of the China Common Rail System, such as increasing the injection pressure, and different vehicle model improvements are also different, such as heavy-duty commercial vehicles that require the addition of tail gas after-treatment systems—selective catalytic reduction devices. (SCR).†We have always believed that diesel is the most reliable and convenient source of power. Bosch has been working tirelessly for cleaner diesel engines. This is in line with the environmental protection policies of governments around the world. Mr. Stefan Frantz said: “In Europe, the proportion of diesel passenger vehicles is more than 50%. However, Chinese users’ understanding of diesel vehicles is still based on the “black smoke†and “noiseâ€, so they are not willing to Paying for diesel passenger cars; on the other hand, there are not a large number of diesel passenger cars of various types available on the market, people do not have the opportunity to learn advanced diesel technology.The situation is changing, and many new models are equipped with Bosch. The diesel passenger car of the common rail system has already been introduced to the market and has been recognized by users.†The author of this article once drove the Audi Q7 using Bosch common-rail diesel technology and experienced first-hand that the power and comfort of the car was very good. “The particulate emissions of the Euro 5 diesel engine using Bosch diesel technology are now 98% lower than in the early 1990s. Technology is continuously improving, but people also need time to accept it.†“In order to better support the development of modern diesel technology in China, Bosch has established a joint venture with Weifu and established Bosch Automotive Diesel Systems Co., Ltd. in Wuxi to produce and develop localized products to better serve the Chinese market.†Mr Stefan Frantz said, “The injectors used in commercial vehicle common rail systems now being manufactured for Chinese customers have all been domesticated, and we are also stepping up to achieve more localized production of other components. We are not only local Production and assembly, and development and production of localized products suitable for the Chinese market." Reports from China Bus Network and China Truck Network believe that in China, the widespread use of diesel engines in passenger cars and trucks has benefited greatly. Diesel engines are more powerful and more reliable than other conventional powertrains. The development of diesel engine technology supports China's huge fleet of passenger trains and trucks. We also hope that there will be more opportunities for more truck users and bus users to learn more about the new generation of diesel technologies that are energy-efficient and environmentally friendly, and to allow Chinese passenger cars and Chinese trucks. Enjoy more energy, environmental protection and more powerful diesel power.
