在陆军采用的各种类型发动机中,柴油机占居主要位置。虽然这种柴油机被认为是最过时的,但人们仍继续不断对其进行改进。在美国、西德、日本、加拿大以及其它一些资本主义国家里,风冷式柴油机已开始装备在坦克、步兵战车、装甲运输车、自行火炮、工程车辆和多用途汽车上。目前生产的发动机主要是4和6缸直列式以及8、10和12缸V型。 Among the various types of engines used by the Army, diesel engines dominate. Although this type of diesel engine is considered the most out of date, people continue to improve it. In the United States, West Germany, Japan, Canada and other capitalist countries, air-cooled diesel engines are beginning to be equipped on tanks, infantry fighting vehicles, armored carriers, self-propelled guns, construction vehicles and utility vehicles. The engines currently produced are mainly 4 and 6 cylinder in-line and 8, 10 and 12 cylinder V-type.
