Effect of Higher Content N-butanol Blends on Combustion, Exhaust Emissions and Catalyst Performance of an Unmodified SI Vehicle Engine
Original language description
To reduce exhaust emissions and dependency on petroleum based fuels, various alcohols have been considered as neat fuels or gasoline substitutes for spark ignition engines. In this study, the effects of blends of 30% and 50% of nbutanol (1-butanol) withgasoline on combustion process, engine control unit adaptation and exhaust emissions before and after a three-way catalyst were examined on a 1.2-liter, three-cylinder spark ignition engine coupled to engine dynamometer. The adaptation of engine controlunit and its effects on the fuel injection rates and air-fuel ratio, along with in-cylinder indicated pressures, exhaust gas temperatures and gaseous emissions were investigated at thirteen steady-state operating points. Where the engine maintained stoichiometric air-fuel ratio on gasoline, the engine control unit has adapted relatively successfully: Stoichiometric operation was observed on both butanol blends, with lower HC both before and after catalyst, comparable CO, and slightly hig
