| Abstract: | A corresponding physical and mathematical model was established for Daihatsu 6PSHdM-26H supercharged four-stroke turbocharged marine diesel engine,and the thermal process was simulated and analyzed.Taking surging as an entry point,a numerical method of turbocharging system was set up.The calculation results and analysis of the impact of increased delayed combustion on the running performance of diesel engine were given.Fuel injection system failure or poor quality low-grade heavy fuel oil would raise the ex... |
| Keywords: | 4-stroke medium-speed turbocharged marine diesel engine fuel injection system failure delayed combustion compressor surging performance analysis |
