Performance and Emission Analysis of Two Stroke Dual Sparkplug SI Engine

An internal combustion (IC) engine has a predominant role in a low power generation and a virtual monopoly in mobile applications today.One of the best methods to improve the engine performance and reduce the exhaust emission in a SI engine is by using introduction of twin spark into the combustion chamber.Two stroke spark ignition engines have high exhaust emissions and low brake thermal efficiency due to the short circuiting losses and incomplete combustion, which occur during idling and at part load operating conditions.Dual spark ignition system has proved their potential in improving the performance of the engines and improved emissive characteristics as compared with the single spark plug ignition system.Experiments were conducted at different load conditions and different types of engines have proved that dual spark plug ignition engines are surely better than a single spark plug engine.To compare, single-spark plug configurations were also considered for other selected spark plug locations.Current paper investigates the effect of multi spark plug to the single spark plug on the basis of the performance of engine and emissive characteristics of engine.The result shown that the considerable improvement in the performance of engine output and considerable reduction in BSFC, HC and Co emission in multi spark plug mode.
