The combustion process in a spark ignition engine is a progressive reaction, and thus certain factors such as the timing of ignition, combustion duration, the end of combustion etc. have considerable effect on performance of an engine. These parameters affect the maximum pressure that is developed inside the cylinder during combustion. Thus the output of the engine can be controlled to a certain extent by variation of important engine parameters mentioned. The effect of ignition timing on parameters such as maximum cylinder pressure, power, torque, fuel consumption is studied in this paper. Thus the optimum value of ignition angle is simulated by single zone model and verified with experimental data.

Keywords: Ignition timing, peak cylinder pressure, combustion duration, FMEP, BSFC.
