Study on Single Cylinder Engine for Performance and Exhaust Emission with Diesel, Bio Diesel, LPG and CNG.

The present work deals with Study of performance and emission on single cylinder air cooled naturally aspirated direct injection diesel engine. Same engine was converted into spark ignition engine with suitable compression ratio to adopt LPG and CNG as a dual fuel application. CFD analysis was done to review and subsequently increase the cooling capacity of the engine. Same spark ignition engine was further converted into water cool version to study improvement in engine performance.

Engine performance comparison has shown 17% improvement in power with gasoline as compare to its parent diesel engine and there was drop in power by 12% with LPG and CNG as fuel when compared with gasoline engine. Engine has met proposed Bharat Stage-III emission norms with all fuel on chassis dynamometer. Substantial Reduction in CO₂ emission was observed with CNG fuel.
