Optimization of Marine Medium Speed Diesel Engine Performance based on Multi-Injector System
نویسندگان
چکیده
Multi-injector system is potential to improve thermal efficiency and NOx emission of diesel engine at the same time. In order optimize combustion Marine medium speed engine, with a multi-injector simulated analyzed by CFD software Converge. this research, two injectors are installed side cylinder head while central injector maintained. Various injection directions strategies fuel spray combustion. The analysis results show that angle plays key role for effective improvement, since complex jet-jet interaction impingement may deteriorate if arrangement was not set properly. Once direction has been optimized, ratio three optimized improved lower emission. could increase rate into cylinder, leading high brake power consequently increased 1.26% decreased 16% best optimization.
