Analysis of components of self-ignition engine exhaust gases powered with biofuels

Abstract

Ecological approach to transport including the fuel which is used in combustion engines involves a necessity of alternative solution application. The study shows test result analysis of the amount of exhaust gases affecting natural environment. The tests were performed for a 81W self-ignition engine with a direct fuel injection. The experiment was conducted for a fuel mixture containing 70% of diesel oil 30% of fatty acid methyl esters. The results regarding concentration of fuel components obtained for the analyzed mixture were compared with the results obtained for a diesel oil without fatty acid methyl esters. Based on the analysis, it can be said that 30% additive of fatty acid methyl esters to diesel oil is not enough to decrease the amount of harmful substance emission to the atmosphere by a power unit.
