Simulation Study on Single Cylinder Spark Ignition Engine with Varying Ethanol Gasoline Blends

This study investigates the effect of a mixture of ethanol and gasoline in a four cylinder cycle spark ignition OHV engine in a cylinder fitted with a generator. The simulation is performed in professional engine simulation software from AVL Austria designated as BOOST. AVL BOOST is used as a computational thermodynamic simulation tool to analyze performance and emission characteristics for individual mixtures of ethanol and gasoline 0 , 10 , and 30 of ethanol by volume . . Studies are performed for 40 , 50 , 60 , 70 , 80 , 90 , 100 load conditions for constant engine speed. The results were compared to pure gasoline. This showed that as ethanol content increases, power and torque decrease. Fuel consumption increases with an increase in ethanol percentage. CO emissions decrease with an increase in ethanol percentage while HC emissions decrease at higher percentage loads. NOX emissions increase with increase in ethanol percentage.
