Abstract
The CFD simulation model of the spray and combustion in the cylinder of the diesel engine was built by mean of the FIRE software and was checked through the test; the influence of the common rail pressure and the injection period on the velocity field, fuel-air equivalent ratio distribution and the temperature field were studied when the injection mass was constant; the influence of injection timing on the velocity field, fuel-air equivalent ratio distribution and the temperature field was studied when the common rail pressure and the injection period were constant. The study provided the foundation to match the high pressure common rail system parameters.
