"Diesel technology is currently the most suitable vehicle technology for China's future development," said representatives from the government, automobile manufacturers, oil companies, and research institutes at the International Diesel Development Forum held in Beijing. All were optimistic about the future of diesel in China. Bosch Group, the world's largest auto parts manufacturer, has made a strong commitment to advancing diesel technology in China, aiming to support energy efficiency and emission reduction goals.
Over the past 15 years, diesel technology has seen significant global advancements. Compared to gasoline vehicles, diesel cars consume 20–30% less fuel and offer better performance. Moreover, modern diesel technology has completely transformed the traditional image of diesel vehicles as smoky and noisy. In 2005, particulate emissions from diesel cars had dropped by 91% compared to 1990 levels. Today, diesel vehicles are widely accepted in many developed countries, with France, Italy, and Germany having diesel cars account for 72%, 66%, and 43% of their passenger car markets respectively.
Experts at the forum emphasized that developing diesel technology could significantly help China save energy and reduce emissions. According to forecasts, China's vehicle ownership is expected to reach 60 million by 2010 and 150 million by 2020. If diesel vehicles make up 10%, 20%, or 30% of passenger car ownership by 2020, the country could save 9.36 million, 18.87 million, and 28.37 million tons of crude oil, respectively. This would lead to a reduction in automotive oil use of 3.3%, 6.7%, and 10.1%, and decrease oil imports by 3.7%, 7.5%, and 11.3%. A 30% diesel share could reduce external oil dependence by over 10%.
Compared to hybrid and electric technologies, diesel remains the most mature and directly applicable option in China. While new technologies like fuel cells, electric vehicles, and natural gas vehicles are gaining attention, experts agree that internal combustion engines, hybrids, and alternative fuels will coexist for the foreseeable future. By 2020, traditional internal combustion engine vehicles are still expected to make up around 30% of the market, while advanced diesel and hybrid vehicles will account for about 65%. The rest will be electric or fuel cell vehicles. However, fuel cell vehicles are still far from mass production.
Bosch believes that advanced diesel technology, due to its maturity and practicality, doesn't require extensive infrastructure changes, making it an efficient path toward energy conservation and environmental protection. Dr. Kong Lude, Bosch Group Director and Head of Asia Pacific Affairs, highlighted that the Chinese government’s 11th Five-Year Plan emphasizes building an energy-efficient and environmentally friendly society. With nearly 80 years of innovation in diesel technology, Bosch is committed to supporting China's development of modern diesel systems.
Bosch has partnered with China Weifu Group to develop diesel technology in China. In November last year, a new plant for Bosch Automotive Diesel Systems was completed. In March of this year, the first domestically produced heavy-duty diesel engine equipped with Bosch’s common-rail system was launched. This engine meets Euro III standards and can be upgraded to meet even stricter European IV and V standards, offering low fuel consumption and noise levels.
