Heat flux and temperature distribution studies were carried out in the combustion chamber of a precombnstion chamber diesel engine running on dual fuel of diesel and natural gas. The test rig consisted of a pre-combustion chamber single cylinder diesel engine fully equipped for temperature measurements across different points in the cylinder head, cylinder liner and other critical areas of the combustion chamber. Four traversing thermocouples were installed across the cylinder head and five were fitted along the cylinder liner. Fixed thermocouples were fitted in the pre-combustion chamber tip, fuel injector nozzle tip, exhaust valve scat and exhaust port. The effect of engine load on the heat flux and temperature level in the different places of the combustion chamber of the engine is presented for both diesel engine and dual fuel engine. The use of natural gas in the dual fuel engine considerably affected the temperature level and heat flux in the combustion chamber.
