火花点火发动机爆震燃烧测量方法的初步研究 - At the conditions with the same fuel injection quantity per cycle and the same engine speed , with the increase of the additive mass fraction in the fuel , the ignition and heat release timings brought forward , the peak of heat release rate increased and the operating range at low engine load was enlarged obviously . however , excessive additives will make the engine be prone to knock , run rudely and shorten the operating range at high engine load
在相同循环喷油量和相同转速的条件下,随着添加剂质量分数的增加, hcci着火和燃烧放热提前,燃烧放热峰值提高,低负荷工况范围明显拓宽,但过高的添加剂质量分数会使得发动机爆震,工作粗暴,导致高负荷工况变窄。 - This paper analyses the cause of knock phenomena of vehicle engine , its detection method and the way to avoid it by electronic control unit ( ecu ) for vehicle engines . a brief discussion about the ecu structure , control principle and software are presented . through the electronic control , the dynamic performance , fuel economy , and exhaust emission of the engine are considerably improved
