Numerical Simulation on the Effects of Angle of Nozzle on Combustion and Emission for Diesel Engine

Abstract:

A double ω-combustion chamber matched with a double-row nozzle combustion system was proposed to improve the spray space distribution and the mixture formation quality for diesel engines. The cylinder spray, mixture formation and combustion process of a double ω-combustion chamber were simulated by using AVL FIRE software. With different nozzle angles, the effect of which on air velocity, concentration and temperature fields as well as combustion and emission characteristics in the combustion chamber was analyzed. The results show that the spray angle of the nozzle has a great influence on combustion and emission performance. Using the double-row nozzle injector can effectively improve the quality of the mixture, moreover, compared with single-row nozzle injector, the max soot emission was reduced by 57.8% and the ultimate formation was also lower.
