Experimental Investigation of Diesel Engine Using Gasoline as an Additive

Abstract—In the present study the effects of gasoline has been investigated empirical in a single cylinder vertical diesel engine for gasoline-diesel mixture. The effects of 0% 4%, 8% and 12% (by volume) gasoline mixed directly to diesel and the effect has been looked upon experimental at speed of 1000 (rpm). From experimental results it is determined that by application of gasoline addition effective power output increases at the level of 4-9% and fuel consumption decreases by approximately 6%. In this study we found that increasing the gasoline volume fraction decreased the fuel density, kinematic viscosity, and surface tension. The blending of gasoline caused a decrease in droplet size by increasing the small droplets and decreasing the large droplets because the surface tension decreased with the addition of gasoline fuel, thereby inducing an increase in droplet instability. On the other hand, gasoline blending resulted in an extension of the ignition delay and the formation of a more homogeneous mixture. These combustion characteristics caused the simultaneous reduction of NOx and soot. However, the HC and CO emissions were slightly increased. The difference in HC and CO emissions between pure diesel and gasoline blended diesel fuels decreased as the engine load increased. An increase in engine load diminished the effects of gasoline blending on combustion performance and exhaust emissions
