| Abstract: | 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. |
