摘要
研究了扫气对充量系数、燃烧以及排放的影响。试验结果表明,随着扫气的增强,充量系数增大,THC升高而NOx下降;受气流运动的影响,混合气的燃烧并未随着扫气的增强而增大,在气门重叠角为0℃A时,发动机的燃烧最好,扭矩最大。
The influence of scavenging on volumetric efficiency, combustion, power and emission were studied. The results show that with scavenging enhanced, volumetric efficiency, THC was increased and N0x was reduced. The combustion was affected by the state of dynamic mixture, The best combustion and torque were obtained at the overlap angle was 0 ℃A.
