| Abstract: | To reduce emission discharge, fuel consump tion and noise of diesel engine, the steady airflowin intake system under different valve lift is numerically studied for an electronically controlled four valvevehicle diesel engine by 3D Computational Fluid Dynamics (CFD) numerical simulation. The characteris2tics of its intake flow field, valve opening effect on generation of swirl in cylinder, and changing rules ofswirl, are revealed. The simulation results p rovide theoretical directions to design intake port, organize andop timize fuel injection and combustion of electronically controlled four valve diesel engine |
