Effect of Gasoline Fumigation on Diesel Engine Performance and Emissions

Abstract

The present study investigates theoretically the effects of gasoline fumigation on single-cylinder diesel engine performance and emissions. The results indicate that a premixed charge can be obtained by early injection of gasoline because of the high volatility of gasoline. More homogenous mixture was obtained and the fuel burned faster and efficient. The smoke emission was reduced and engine output was increased. Coupling with EGR technique could reduce the NOx emissions simultaneously.
