| Abstract:Research was carried out on the black smoke phenomenon of a marine high power medium speed diesel engine，the key performance parameters such as the loading process and the excess air coefficient of the diesel engine were analyzed to determine the generation conditions and mechanism of black smoke of the diesel engine，and the fuel injection strategy was optimized.The real ship test shows that the black smoke phenomenon of the optimized diesel engine has been significantly improved. |
| Key words: supercharged diesel engine excess air coefficient black smoke control strategy |
