Abstract

The intake air temperature is an important factor that determines the combustion characteristics of the GPPC combustion model, controls the formation of diffuse combustion, and has a direct consequence on the formation of toxic emissions of HC, CO, NOx and soot in the GPPC type. In this study, the author investigates that the injection time changes with the operating conditions being kept constant: keeping the injection mass ratio fixed at 50-50, the pilot start of injection -35 CAD ATDC and the main start of injection time at the point of injection. top dead, engine rotational speed 1500 rpm, intake air temperature varies from 165 oC to 205 oC, intake pressure 1 bar and injection pressure 400 bar. Through the experimental results, the simultaneous effects of the combustion process with the cold flame and the jet of the penetrating main injection are evaluated to affect the combustion rate of the main combustion process. In addition, the maximum combustion temperature, the rate of increase of pressure in the cylinder and the combustion efficiency and indicator efficiency of the engine are also evaluated to find the impact of intake temperature on operating mode of the engine.
