Abstract

This paper deals with the measures that may be taken in the engine and outside the engine in an effort to reduce the harmful motor exhaust gas concentration emissions. These measures are being taken and elaborated with the prospect of meeting the increasingly requiring legal provisions on allowed concentrations of harmful exhaust emissions. This is meant to show the extent to which individual measures influence the level of emission of individual components, discussing at the same time the character of individual measures. The paper further reiterates the indispensability of optimization of all measures taken in the engine to reduce the emission of harmful exhaust gases to the minimum.
