Performance and Emission Analysis of Four Stroke Twin Spark Single Cylinder SI Engine Fuelled with Gasoline and CNG –a Technical Review

Imran G. Qureshi, Prof. R. J. Jani

Abstract :

This paper describes review on performance and emission characteristics of twin spark ignition engine fuelled by gasoline and natural gas. Here, it will be shown that due to lower volumetric efficiency and lean effect in CNG Fuelled SI engine, the maximum torque generated is diminished compared to gasoline fuelled engines. We showed that the torque reduction can be recovered and performance of single spark CNG engine can be enhanced by modifying twin spark ignition system
