Heat transfer model
 A more complex model is to incorporate models of heat transfer, crevice effects
and thermodynamic properties of the cylinder charge into the energy conservation
equation. This was first done in [Gatowski et al., 1984]
 The convective heat transfer rate to the combustion chamber wall can be
calculated from relation:
 There are a lot of equations using to calculate heat transfer coefficient hc
