Abstract:
-This study aimed to determine the emission gases and performance of diesel engine using 20, 40, 60 & 80 % of waste cooking oil methyl ester and diesel on volume basis. The blends were tested in a four stroke single cylinder diesel engine. The essential physical and chemical properties like specific gravity, viscosity, flash point and calorific value were determined after the study. The emission map of the CO, CO2, NO, HC emissions and smoke opacity were determined and the performance parameters like brake specific fuel consumption, brake power and brake thermal efficiency were obtained and analyzed at varying engine speeds, such as 1400, 1800, 2200, 2600 and 3000 rpm, and constant engine load. Results showed that there is a decrease in the brake thermal efficiency and brake power whereas there is an increase of brake specific fuel consumption for different blends of waste cooking oil methyl ester and diesel compared with diesel fuel. For the emissions results, there was a reduction in smoke opacity and carbon monoxide but there was a slight increase in the amount of unburned hydro carbon emissions and NOx emissions.
