Improvement of Combustion and Exhaust Gas Emissions in a Passenger Car Diesel Engine by Modification of Combustion Chamber Design

An Experimental Investigation on a New Combustion System of Diesel Engine for Performance Optimization

“…As we known, the fuel injection system, the intake swirl and the combustion chamber geometry determine the mixture formation of the fuel and air in diesel engine, and also affect the diesel engine performance. Among these three aspects, the relationship between the fuel spray and the combustion chamber geometry is the key factor which influence mixture formation in combustion chamber, further affect the mixture ignition and the combustion process, and finally determine the brake specific fuel consumption and emissions of diesel engine [1][2][3]. Currently, many researchers have pay their efforts to match the fuel spray and combustion chamber geometry in diesel engine [4][5][6].…”
