Multidimensional modeling of the effect of fuel injection pressure on temperature distribution in cylinder of a turbocharged DI diesel engine

摘要

In this study, maintaining a constant fuel rate, injection pressure of 275bar to 1000bar (275×102kPa to 1000×102kPa), has been changed. Effect of injection pressure, the pressure inside the cylinder on the free energy, power, engine indicators, particularly indicators of fuel consumption, pollutants and their effects on parameters affecting the output of the engine combustion chamber have been studied in droplet diameter. Finally, the effects of fuel mixture equivalence, Cantor temperature, soot and NOxdue to the increase of injection pressure, engine efficiency and emissions have been examined.
