在世界上,机车柴油机的发展趋势主要是不断提高柴油机的功率、经济性、可靠性和寿命。已展出的现代化机车用低速柴油机的主要参数示于表1,机车用高速柴油机的主要特性见表2。从这两张表上可以看出,目前已经有许多4000马力(2940瓩)的柴油机,而5000马力(3675瓩)以及5000马力以上的柴油机也不是绝无仅有的了。各柴油机厂为提高功率而所 In the world, the development trend of locomotive diesel engines is mainly to constantly improve the power, economy, reliability and life expectancy of diesel engines. The main parameters of the modern low-speed diesel engine for locomotives exhibited are shown in Table 1, and the main characteristics of the high-speed locomotive diesel engine are shown in Table 2. As you can see from these two tables, there are already many 4,000 horsepower (2,940 kilowatts) diesel engines, and 5,000 horsepower (3,675 kilowatts) and diesel engines over 5,000 horsepower are not uncommon. The diesel engine plant to improve the power of the place
