Optimizing Spark Timing of Spark Ignited Ethanol Engine


Alcohol is a good alternate fuel by comparing its performance, availability and renewability against fossil fuels. Ethanol is widely used in IC engines by blending small amount with petroleum fuels, but it is not solely used because its high boiling point and self-ignition temperature makes it difficult to burn in engines because, auto ignition also is not possible because of its high octane number and engine needs spark ignition. In order to overcome this problem we need a spark ignited engine with high compression ratio. So a high compression ratio engine is modified into spark ignited engine. A carburetor with 2mm main jet to supply excess fuel into engine is used in order to compensate its low calorific value. The engine used in this experiment was a single-cylinder direct injection diesel engine with a cylinder bore of 95mm, a stroke of 110 mm and a compression ratio of 13:1. The rated power was 5.3 kW at 1500 rpm. The engine has been tested at different loads for Ethanol against spark timings when piston is at TDC, 5 degree before TDC, 10 degree before TDC, 15 degree before TDC respectively. The optimum spark timing is found among the experimental basis for Ethanol.
