摘要
为改善轻型商用车柴油机的排放,在喷油过程中采用后喷射控制策略,研究了后喷射控制参数对发动机性能和排放的影响。试验结果表明,通过对后喷射定时、后喷射喷油量的优化,排气烟度大大降低,而其他性能指标和排放指标无明显恶化。
The post-injection control strategy was used to improve the emission of light-duty commercial diesel engine.The influence of post injection parameters on engine performance and emission was researched.The results show that the exhaust smoke decreases greatly by the post-injection timing and injection quantity optimization,while the other performance and emission indices have little deterioration.
