Paper Title
Reducing HC Emissions with Ethanol use in an Internal Combustion Engine

In this study, 1-D numerical analysis model of a spark ignition engine has been created. So, an engine test system has been modeled with using analysis program. Results of the HC emissions analysis which has been used gasoline and ethanol have been obtained for a total of five different engine speeds ranging from 1000 rpm to 5000 rpm with an increment of 1000 rpm. Effects of both gasoline and ethanol on HC emissions of the spark ignition engine based on engine speed have been revealed. Emission value also in terms of HC has been commented. Results of 1-D numerical analysis model have been shown with graphics. Keywords - Spark ignition engine, Emissions, 1-D engine modeling, Ethanol
