| Abstract: | Taking a marine high power and high turbocharged diesel engine as the research object, the influence of different scheme of exhaust pipe and different Miller timing on diesel engine performance had been studied through simulation method. The results showed that under the premise of meeting the emission regulations, the thermal load and fuel consumption rate could be reduced by matching exhaust pipe with higher diesel engine exhaust energy utilization ratio and Miller timing with appropriate intensity, which was beneficial to improve the reliability and economy of diesel engine. |

| Keywords: | marine high turbocharged diesel engine Miller cycle exhaust pipe simulation |
