Analytical Model for Combustion Process and Heat Exchange in Spark Ignition Engines

The method of temperature calculation in a combustion space of spark ignition engine is presented with regard to differentiation of this temperature in consequence of flame front existence.

The method of utilization of this calculation for determining of a distribution of surface heat transfer coefficient between working medium and piston head surface is described. Results of these calculations are utilized for the analysis of temperature distribution in piston cross-section.
