Experimental investigation of various Spark Plug gap on Four Stroke Single Cylinder S.I. Engine.

Abstract

The SI engines are the most common for passenger cars and their development is therefore very important. It is believed that not only the spark energy, but also the spark location may play an important role in the interaction with mixture composition and charge motion; moreover the spatial distribution, between the spark electrodes gap, of the energy supplied by the discharge can also play a role in the development of Engines and performance and emissions, in this study experiments were carried out on a single cylinder petrol engine to understand the effect of spark plug gap on SI engine.
