The paper deals with problems of model analysis of the process of exhaust gases components formation in internal combustion engine working with combustion initiation from ignition dose of fuel injected directly into the working space. In result of scientific-research works carried out in the Chair of Internal Combustion Engines of Cracow University of Technology on the basis of a four stroke engine a driving unit was elaborated which may work both with spark ignition and combustion initiation from a ignition dose of fuel. Application of two combustion systems in engine aimed at combining the advantages of spark ignition with compression ignition driving units. Such an engine is characterized by fuel consumption comparable with that gained by compression ignition engines, whereas, the exhaust gases composition is similar to that occurring in up-to-date spark ignition engines. Similar assumption concern the Homogenous Charge Compression Ignition - HCCI system which seems to be a future solution of internal combustion engines, nevertheless, up till now, in spite of intensive works in many countries all over the world, one did not succeed to control the combustion process in a large range of rotational speeds and loads what would give the possibility of using it in traction application. The solution proposed in the patent application by Prof. B. Sendyka is not burdened with this drawback since the moment of occurrence of volumetric ignition of the formed mixture in the process of filling is tightly connected with the moment of fuel dose injection. In result of simulative studies carried out by use of KIVA-3V software on the discussed solution it was stated that the process of exhaust gases toxic components formation in engine working in the mode of ignition from pilot dose does not depart in generally form from that which occurs at work with spark ignition.
