Heat transfer is the exchange of thermal energy between physical systems. The rate of heat transfer is dependent on the temperatures of the systems and the properties of the intervening medium through which the heat is transferred. The three fundamental modes of heat transfer are conduction, convection and radiation.

Detonation is different, butcreates the same problems as pre-ignition. The symptom is also similar, a pinging noise on acceleration.
