Keywords: Keywords: reciprocating engines, fuel combustion, chemical turbulent heat-mass exchange, combustion in flame front.

Mathematical models have been developed to describe generation of air/gasoline mixture and its combustion in flame front based on chemical kinetics principles. Simulation yielded thermal flux function, combustion velocity, flame front output temperature and mix composition for various flame front areas, taking account of mix non-uniformity.

Keywords: engine cylinder head

New method is offered to calculate boundary conditions for the analysis of thermal load exerted on engine cylinder head from gas/air passages and combustion chamber. The analysis procedure is split into several steps, each step being considered in detail. The results of experiments and simulation are shown to be satisfactorily converging.
