二冲程发动机自1881年投入实用以来,一直在轻汽车制造业中占有重有地位,可是到了本世纪70年代其地位却日益下降。目前,除了摩托车使用二冲程发动机以外,几乎看不到采用二冲程发动机的汽车了。不久前在日本东京举办的汽车展览会上,日本丰田汽车公司和富士重工业公司展出了他们的新一代二冲程发动机,该发动机已解决了效率不高和污染严重等缺点。现在世界许多汽车公司都在大力开发新一代的二冲程发动机,二冲程发动机大有东山再起之势。 美国福特汽车公司已研制成一种1.2L3缸二冲程发动机,并用在新设计的“扎克牌”货车上。该公司
The two-stroke engine has enjoyed a significant position in the light automotive industry since it was put into operation in 1881, but its status has been declining by the 1970s. Currently, except for two-stroke motorcycles, almost no two-stroke engines can be seen. At a motor show recently held in Tokyo, Japan, Toyota Motor Corporation and Fuji Heavy Industries Co., Ltd. exhibited their next-generation two-stroke engine that has solved the shortcomings of inefficiency and pollution. Now many car companies in the world are vigorously developing a new generation of two-stroke engines, two-stroke engines have a comeback. American Ford Motor Company has developed a 1.2L 3-cylinder two-stroke engine, and used in the newly designed “Zack” trucks. The company
