ABSTRACT
The article presents the differences in emissions of a passenger car with a compression-ignition engine fueled by vegetable fuel - rapeseed oil with n-hexane and diesel fuel. Emission tests were carried out on a chassis dynamometer in selected phases of the world harmonized light vehicle test procedure. Carbon monoxide, carbon dioxide, nitrogen oxides, total hydrocarbons and non-methane hydrocarbons were measured based on the WLTC Class 3b driving cycle. The effect of engine operating conditions on exhaust emissions when fueled with the fuels studied was described. A regression model was developed to estimate the level of pollutants in the exhaust gas.
