| Abstract: | A simulation model was built based on RT-Flex60C marine intelligent low-speed marine diesel engine,and was validated by data from hardware in loop（HIL） simulation test bench developed independently for large intelligent diesel engine’s electrically controlled exhaust valves,as well as data from diesel engine bench test.Based on these research,simulation analysis was carried out on the effect on performance of mairne intelligent low-speed diesel engine by different opening and closing angles of electrically controlled exhaust valves.The optimized opening and closing angles of exhaust valves on RT-Flex60C was given according to the analysis results. |
