A study of the engine combustion, instantaneous heat transfer and exhaust emissions during the warm-up stage has been carried out on a Rover K16 four-cylinder four-valve spark ignition engine. The instantaneous heat transfer has been obtained by an unsteady two-dimensional analysis of the instantaneous surface temperature measurements. The effect of the wall temperature during warm-up on these engine parameters has been investigated under different load and speed conditions. A simplified single-zone heat transfer model has been used to model the engine heat transfer during the warm-up stage. The experimental results show that the increasing wall temperature during warm-up has an impact on the burn duration, in-cylinder heat transfer, and exhaust emissions, such as hydrocarbons and NOx.
