1-D Simulation of a Diesel Engines Injection Timing

Abstract

Using GT-POWER to simulate a diesel engines injection timing, calibrating simulation model has been done according to experimental data. Analysis of the effect on engine power characteristics and emission characteristics caused by different pre-injection timing and main injection timing is the main work. The simulation results show that, the output torque and NOx increased when the injection timing is advanced. In contrast, the soot emission is decreased when the injection timing is advanced.
