Abstract

The paper describes the results of research on the emission of limited exhaust components from a single-cylinder, research engine of the AVL series 5402 powered by mixtures of rapeseed oil and diethyl ether. Rapeseed oil was used in the research, to which 10, 20, 30 and 40% by volume of diethyl ether was added. The physicochemical properties of the prepared fuel mixtures and their impact on the emission of limited exhaust components, in particular particulates, nitrogen oxides and unburned hydrocarbons, were evaluated. It was found that the addition of DEE to rapeseed oil helps to reduce the emission of harmful exhaust components to the environment, in particular soot particles and unburned hydrocarbons. Diethyl ether added to rapeseed oil has no significant effect on changing the emission of nitrogen oxides. The indicated problem is a barrier typical of the fuel combustion process and is slightly dependent on its type. With this in mind, it should be noted that reducing NOx emissions to the environment requires a change in fuel combustion towards the implementation of the so-called low temperature process. In conventional combustion systems, the reduction of NOx emissions will still require the use of additional treatment systems such as SCR, i.e. selective catalytic reduction.
