摘要
柴油机因具有热效率高、经济性好、低速大转矩、中大负荷CO、HC排放低、可靠性好和寿命长等特点,而广泛应用于各类汽车上。在欧洲,每年对柴油机的需求量以23%的速度增长,我国对柴油机的需求量也逐年增大。为了缓解能源危机和环境污染,开发柴油机代用燃料已经迫在眉睫。文章分析了柴油机代用燃料生物柴油、二甲醚和天然气的应用现状及特点。
Diesel engine is widely used in all kinds of automobiles because of its thermal efficiency, good economy, low speed and high torque, medium and large load CO, low HC emission, good reliability and long life. In Europe, the demand for diesel engine is increasing at 23 % per year, and the demand for diesel engine is increasing year by year. In order to alleviate the energy crisis and environmental pollution, it is urgent to develop alternative fuel for diesel engines. This paper analyzes the application status and characteristics of diesel fuel, dimethyl ether and natural gas.
