All in all , additives are beneficial to improve the ignition of hcci at low engine load and extend the operating range . nevertheless , the knock happens obviously while the range is extending at the high engine speed and load 总之,添加剂有利于改善hcci发动机低负荷着火和拓宽工作范围,但是在发动机高转速和高负荷工况下,在工况范围拓宽的同时, hcci爆震倾向明显,发动机工作不稳定。
Hc and co emissions are very high . to control the ignition timing and extend the operating range of hcci , the experimental research of hcci combustion process was carried out on a 4 - cylinder diesel engine . one of the cylinders was modified for hcci combustion with additives 针对控制hcci发动机着火时刻和拓宽其工况范围,本文在一台经过改造的四缸柴油机的第四缸进行hcci燃烧试验,研究了添加剂对hcci发动机着火和燃烧过程的影响。
Aiming at the insufficiencies in measuring accuracy and operating range of most domestic velometers , this dissertation is focused on the research of ultrasonic spread spectrum speed measurement . 1 . the operating principle and implement method of ultrasonic spread spectrum speed measurement are studied 针对目前国内测速仪器在测量精度和作用距离方面存在的不足,开展了超声扩频测速技术的研究,主要包括以下内容: 1 .研究了超声扩频测速的原理和方法。
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。
