国外新研制的几种摩托车用二冲程发动机

Several Types of 2-Stroke Engines Newly Developed in foreign Countries

当前各国都在对二冲程摩托车发动机不断进行研究和改进。现将已研制出的几种新型二冲程发动机:分层扫气式二冲程发动机;带辅助活塞的二冲程发动机;混合气加热式二冲程发动机;电子控制的燃油喷射装置。虽然目前这几种发动机尚未达到实用化阶段,但对新机型的开发具有重要的参考价值。

At present, 2-stroke engines are being continously researched and improved in many countries. This paper introduces several types of newly developed 2-stroke engines, such as: stratified charge 2-stroke engine, air-petrol mixture gas heating 2-stroke engine,electronic fuel injection 2-stroke engine and 2-stroke engine with supplementary piston. Though the above-mentioned engines are not commercial now,they can be taken as important reference for developing new engines.
