THEORITICAL INVESTIGAITON OF INFLUENCE OF COMPRESSION RATIO ON PERFORMANCE AND EMISSIONS OF SPARK IGNITION ENGINE

Ragadia Sadiq Y, Dr. Rajesh Iyer

Abstract :

Fuel consumption and emissions is one of the major challenges in the automotive industry, so that need to improve the performance characteristics of the engine. For improving the performance of the SI engine, compression ratio below detonating values is a good option. The variation of compression ratio affects engine emissions as well as performance. So compression ratio is the important design variable to deal with effective performance of the engine. To enhance the performance and reduce emissions, optimal compression ratio for SI engine should be selected. The paper is focused on influence of compression ratio on performance of and emissions of SI engine.
