Abstract

The present experimental work analyses the effect of zinc oxide and aluminium oxide nanoparticles addition in canola biodiesel in single-cylinder water cooled direct injection four stroke compression ignition engines. The nano fluids are prepared from 50 ppm of zinc oxide and aluminium oxide nanoparticles with distilled water through ultrasonication process. Various engine loads of 0, 7, 14, 21 and 28 Nm at a constant engine speed of 1,500 rpm were applied during engine testing. The fuel outcomes were obtained by calculating the average three times repetition of engine testing. Findings reveal that the highest maximum pressure of zinc oxide and aluminium oxide nanoparticles fuel increased by 12.3% compared to canola test fuel. Other than that, the engine brake thermal efficiency and specific fuel consumption show a significant increase by 23% and 9.3%, respectively. Meanwhile, the emissions of zinc oxide and aluminium oxide nanoparticles fuel show a large NOx decrease of 41.6%, 28.5% HC and 40% CO. Addition of zinc oxide and aluminium oxide nanoparticles in biodiesel show positive improvements when used in compression ignition engines.
