This paper presents results of investigations and the assessment of the effects of basic significant parameters of the injection process in an AD3.152UR engine fed with diesel oil and fatty acid methyl esters (FAME) on the concentration of nitrogen oxides and carbon dioxide in the exhaust gas. The basic parameters of the injection process were: the fuel dose per engine operation cycle, spray tip penetration and spray angle, and also the Sauter mean diameter. Tests were carried out on a dynamometer stand equipped with an exhaust gas analyzer, a system for the measurement of fast-varying quantities, and control and measuring instrumentation for the measurement of the engine operating parameters.
