经过一段较长时间的冷落,汽车发动机设计师们又重新对二冲程内燃机产生兴趣。二冲程发动机的功率重量比要比四冲程高15～30％,并具有尺寸小.成本低的优点。重新受到重视主要是基于澳大利亚OEC公司新研制了一种二冲程汽油机用进行内部混合气形成的燃料气动喷雾系统的缘故。装有这种喷油器的二冲程汽油机可望在80年代末用于快艇上,而到90年代初,美国的两家公司准备将这种发动机装到轿车上。
After a long period of neglect, car engine designers are again interested in two-stroke internal combustion engines. Two-stroke engine power than the four-stroke weight ratio of 15 to 30%, and has a small size, low cost advantages. Re-emphasis is mainly due to the Australian OEC company has developed a two-stroke gasoline engine for the formation of the internal mixture of fuel aerodynamic spray system sake. Two-stroke gasoline engines equipped with such injectors are expected to be used on speedboats in the late 1980s, and by the early 1990s, two U.S. companies were preparing to install the engine on a car.
