Experimental Investigation on Single Cylinder Modified Compression Ignition Engine to Spark Ignition Mode

A lot of research has been going on in the field of modification of IC engine and work on dual fuel mode. Most of the modified engine can work on dual fuel mode, but they need to require a pilot fuel to start the working on another fuel. In this research work we modified single cylinder diesel engine that work on dual fuel mode without adding any pilot fuel and focus the performance and emission analysis of that modified engine working on gasoline and LPG at constant speed and same compression ratio 7.6 and compare the result with Diesel engine. Result show that the maximum brake thermal efficiency of modified engine using LPG fuel give higher efficiency then diesel engine but using petrol in modified engine its maximum efficiency will be 31% which is higher than diesel engine .Simultaneously reduction in HC and CO emission using LPG fuel and Brake specific fuel consumption also reduce.
