To Study of Dual Sparkplug In Two Stroke IC Engine

Mechanical Engineering

This paper describes some results of the research in the area of multiple spark ignition engines. Dual spark ignition system has proved their potential in improving the performance of the engines. On applying the dual spark plug in two stoke gasoline engine the combustion could be made proper and the specific fuel consumption could be made to decrease. In this two Stroke gasoline engine the scavenging process will also be improved which is poor in the present single spark plug. The present two-stroke twin spark plug gasoline engine can be made to operate either with single or dual spark plug as per the user’s requirement. 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. An effort is been made to improve the engine parameters i.e. specific fuel consumption and Thermal Efficiency of the engine. This is achieved by using dual spark plug in two stroke gasoline also its effect on the engine parameter is analyzed. A spark-ignition (SI) engine cycle model was used to study the effects of spark plug location on a four spark plug SI engine performance
