Research on Effects of Diameter and Arrangement of Nozzles on Combustion and Emissions in Cylinder

Abstract:

Based on the YD4A75-C3 electronically controlled common rail diesel engine, using CFD simulation software, the combustion and emission’s behavior in cylinder was simulated on the numbers, diameter and arrangement of nozzles. The research results showed: in the condition of the certain total nozzle flow area, the proper nozzle numbers could improve fuel’s atomization quality and increase the uniformity degree of gas mixture. The staggered arrangement of nozzles could reduce interference and overlap among the adjacent fuel sprays and increase the air utilization and the space distribution of fuel, finally, the degree of mixing was increased obviously.
