Abstract

The present research experimentally investigates the performance and emission characteristics of LPG-Gasoline dual fuel on a gasoline engine. The engine setup consists of four stroke, four cylinder, water cooled MPFI engine with eddy current type loading unit. Experiments have been conducted with different LPG-Gasoline ratio (0%, 25%, 50%, 75%, and 100%) by mass and different speeds from 2000 to 4500 rpm in steps of 500 rpm at full load condition. From experimental investigation it is found that with the 50% usage of LPG, increases the brake thermal efficiency and volumetric efficiency when compared to gasoline for speed range of 2000 rpm to 4000 rpm. LPG will have much lower CO and HC emissions when compared to gasoline. This is a positive effect on environment. But for other LPG-gasoline ratio these emissions going to increases when compared to LPG but it is well below when compared to gasoline for all speeds. NOx emission is more for LPG almost 4 times that of gasoline for all speed conditions. For other LPG-gasoline ratio NOx emission is lower.
