EN The paper presents an explanation of the formation process of toxic exhaust gas components during combustion process of oxygen-enriched mixtures in SI engine. In order to explain this phenomenon the simulation process was carried out, in which the experimental data from dynamometer tests of the 4-stroke SI engine were used. The tests were done at different oxygen volumetric ratios and at increased exhaust gas recirculation ratios until the mixture of oxygen and exhaust gases has not contained any nitrogen. The EGR system was applied in order to decrease gas temperature in the cylinder. Simulation of engine combustion process with oxygen-enriched mixture and with different EGR ratios was carried out by using the program Kiva3v for calculation of full engine phenomena with simple combustion model. This combustion model took into account 10 kinetic and equilibrium chemical reactions. Both experimental and simulation test indicated nonlinear variation of mole fractions of carbon monoxide and carbon dioxide with increasing of oxygen amount in the charge from 21% to 32% by volume. The engine has higher emission of carbon monoxide and carbon dioxide in comparison to the emission of the engine filling with air-fuel mixture in normal conditions. The paper explains from chemical reactions point of view a non-linear change of CO and CO2 emission in a function of the charge oxygen mass ratio at constant oxygen excess ratio. The paper presents the graphs showing variations of emission and volumetric concentration of chosen chemical species in the charge in a function of crank angles and variation of the engine parameters at different EGR and oxygen ratios in the engine charge.
