Describe various empirical models used for heat transfer coefficient in reciprocating engines. Describe why typically radiative heat transfer is not considered

in SI engine but accounted in a diesel engine as it is significant. Investigate and

find out the suitable heat transfer coefficient for SI, CI, and HCCI engines.
