由于能源危机,目前世界各国都在为解决由此而引起的主要问题进行着大量的研究工作。但是在没有找到一种价廉的、并有丰富资源的燃料之前,内燃机的燃料仍是以石油产品为主。从这个基本观点出发,本文对现有各种汽车发动机加以比较,认为近期的汽车发动机仍以往复活塞式内燃机为主,指出活塞式汽油机和柴油机仍有改进的必要和潜力。综合英、美、法、西德、日本和意大利等国最近有关汽车发动机各方面的研究动向可见,近期的汽车汽油机和柴油机的竞争是很激烈的。但是柴油机以它固有的特点,在各种汽车上装用日益增多,并且使用范围已扩大到小客车。
Due to the energy crisis, a great deal of research work is being carried out in various countries in the world to solve the major problems caused by this. However, until a cheap fuel with abundant resources is found, the internal combustion engine’s fuel is still dominated by petroleum products. From this basic point of view, this paper compares the existing automobile engines, and considers that the recent automotive engines are still mainly reciprocating piston engines, pointing out that the piston gasoline engine and diesel engine still have the necessary and potential for improvement. Based on the recent research trends in automobile engines in various countries such as Britain, the United States, France, West Germany, Japan and Italy, the competition between the recent gasoline engines and diesel engines is very fierce. However, with its inherent characteristics of diesel engines in a variety of cars loaded with increasing, and the use has been extended to the small passenger car.
