The performance and heat transfer characteristics of a single cylinder diesel engine in the metal and in the ceramic-coat-insulated configurations were compared at the same speeds, loads and air flow rates. Compared to the metal engine, the insulated engine had a higher brake specific fuel consumption which was attributed to a slower combustion process; the exhaust as well as the time averaged surface temperatures of the insulated engine were higher. The unsteady heat flux amplitudes in the insulated engine were lower which suggested a lower overall heat flux. This lower heat flux was attributed to the lower flame temperatures because of the poor combustion quality in the non-optimized insulated engine.
