The reporter learned on November 2nd, 2010 that China's largest-powered CA6SN1-42E4N2 natural gas engine recently successfully fired once at FAW Wuxi Diesel Engine Factory, filling the gap of domestic high-power natural gas engines of 400 horsepower or more. Qian Hengrong, director of FAW Wuxi Diesel Engine Factory, said that this is a major achievement brought by the company in response to the national energy conservation and emission reduction, strategic adjustment of energy structure, and accelerating the implementation of scientific and technological innovation, and won new competition for FAW to participate in the international natural gas heavy truck market. Advantage.
In recent years, FAW Wuxi Diesel Engine Plant has increased its investment in science and technology, accelerated the introduction of talents, expanded international cooperation, accelerated the development of a number of core technology products with independent intellectual property rights, and has become one of the domestic heavy-duty engine research and production bases. In September 2009, faced with the development trend of the international natural gas heavy truck market, the plant relied on the advantages of scientific research and development formed by the Group and, in conjunction with FAW Technology Center, started the development of the CA6SN1-42E4N2 natural gas engine with the largest domestic power.
According to the person in charge of the project, the CA6SN1-42E4N has a power of 420 horsepower and can be extended down to 390 horsepower. It matches the J5P and J6P liberation heavy trucks and is used in natural gas-rich regions such as Xinjiang, Inner Mongolia and Shanxi, with a driving range of 1,000 kilometers. . At the same time, the CA6SN1-42E4N2 engine has the advantages of advanced technology, superior economic performance, low carbon emission, and reliability and durability. Its large displacement, high degree of enhancement, maximum torque of 1700N.m; use of diesel than the economic, environmentally friendly natural gas as fuel, 100 kilometers to save fuel costs more than 30%; compared with the same power of the diesel engine, carbon monoxide emissions decreased by 90%, carbon dioxide reduction 20%, hydrocarbons reduced by 60%, nitrogen oxides reduced by 60%; no carbon deposition, no dilution of lubricating oil, can effectively reduce component wear, can withstand strong heat load, and extend engine life.
The successful ignition of the A6SN1-42E4N2 natural gas engine reflects the development of high-power natural gas engines by Xichai . The technical level has reached the international advanced level. At present, Xichai has established a new energy automotive subsidiary and will fully implement the industrialization of the CA6SN1-42E4N2 natural gas engine, accelerate the development of natural gas vehicles, and seize the international natural gas heavy truck market.
