A HCCI-DI engine is examined using fish oil bio-fuel at various proportions with neat diesel in DI fuels and petrol as the pilot energy. 20% of petrol is admitted as premixed fuel and the 80% of the charge is injected straight away to chamber at 23°bTDC. The effect of Al 2 O 3 nano additive on DI engine is also investigated. An investigational observation is analysed with DI engine. First, HCCI-DI engine firing is compared at premature stage of combustion. Upto 1.84% improvements in the brake thermal efficiency is witnessed at petrol mixed HCCI-DI engine compared as DI combustion. The blending of Al 2 O 3 nano additive showed 5.88% increase in the performance of the engine. Significant reduction in NOx is observed from the HCCI-DI ignition matched via DI combustion. Fish oil biodiesel fuelled combustion showed decrease in the HC besides CO issues
