Abstract :
Results of numerical analysis of mixture preparation and combustion in SI engine with prechamber are presented in the paper. The numerical model of the engine cycle was built using KIVA-3V code. Calculations were carried out for four values of air excess number: 1.4, 1.6, 1.8, 2.0. Spatial distribution of air-fuel mixture in prechamber and main combustion chamber of the test engine was obtained as a result of modeling. Pressure and temperature variations in function of crank angle as well as spatial distribution of above mentioned quantities at selected crank angles were determined.
