一、燃烧与工作过程的关系在发动机发展的几十年中,燃料品种与发动机工作过程间有着一种固定的相互关系。在外部形成混合气的汽油机,显然是利用了汽油的挥发特性。汽油机的全部燃料在气缸中是处于一种可燃的,即混合良好的状态。很明显,不能采用压缩点燃。这种情况的必然结果是外 First, the relationship between combustion and the working process In the development of the engine for decades, the fuel varieties and the engine has a fixed relationship between the working process. Gasoline engines that form a mixture externally apparently make use of the volatile nature of gasoline. The entire fuel of the gasoline engine is in the cylinder in a flammable, ie well-mixed state. Obviously, you can not use compression ignition. The inevitable result of this situation is outside
