Abstract

Abstract: In order to improve the spatial distribution of injection spray and the mixture formation quality for diesel engines, a combustion system with double ω combustion chamber is proposed to strengthen the motion of airflow in the combustion chamber. The preliminary performance test of combustion system with double ω combustion chamber is made on ZS1100M diesel engine. The results show that the geometrical shape of double ω combustion chamber has a great influence on the fuel consumption and emission performance of combustion system for diesel engine. The fuel consumption and soot emission of 57-type combustion chamber are the lowest under the rated operating condition. Compared with the original combustion chamber, the fuel consumption and soot emission of 65-type double ω combustion chamber are reduced by 2.2% and 8.3%, respectively, at rated operating condition while the NO_x emission remains basically unchanged. 65-type combustion chamber with 2.6 mm nozzle height possesses the optimal fuel consumption and soot emission performance at the rated rotating speed. At the rotating speed of 1 500 r/min, the double ω combustion chamber with double-row nozzle holes shows better fuel consumption rate under the small and medium loads. The proper increment of the upper-row nozzle holes and a decrease in throat diameter could further reduce the fuel consumption rate.
