Noise is a pollutant by the combustion process that may have direct effect upon surrounding environment. In this study, noise measurements were taken for multi cylinders, four stroke Fiat engine converted to run as dual fuel engine on diesel and gaseous fuels of liquefied petroleum gas (LPG) and natural gas (NG). The study focused on the influence of some operating parameters. These parameters included: engine load, pilot fuel injection timing, pilot fuel mass, and engine speed. It was found that using LPG as the main fuel in duel fuel mixture exhibits higher engine noise compared to NG or neat diesel. The results showed that advancing injection timing from optimum ones increased engine sound pressure levels.
