Comparison of Smoke Emissions in Different Combustion Engine Fuels

Goal of this study was to investigate and evaluate an impact of two alternative fuels on smoke emissions in comparison to diesel fuel. This study observes three different combustion engine fuels: biodiesel produced by Meroco, Inc. Company (Alternative fuel I); biodiesel produced in factory situated in Sereď (Alternative fuel II); and conventional diesel fuel (Diesel fuel) from Slovnaft, Inc. Company service station. All measurements were repeated three times. Measurements were conducted by free acceleration test at different engine loads. A statistically significant difference ( 0.05). Tested engine has met the requirements of the EURO 3 emission limit values in relation to the measurement results of particulate matter emissions.
