Experimental investigation of the influence of adding alumina to diesel fuel on the engine performance and emission characteristics

الملخص EN

The present experimental work is conducted to examine the influence ofadding Alumina (Al2O3) nanoparticles to diesel fuel on the characteristicof the emissions and engine performance.

The size of nanoparticles whichhave been added to diesel fuel to obtain nano-fuel is 20 nm.

Three doses of Aluminum oxide were prepared (25, 50 and 100) ppm.

The nanoparticlesmixed with fuel by mechanical homogenous (manual electrical mixer) andultrasonic processor.

The study reveals that the adding of Aluminum oxide (Al2O3) to gas oil (Al2O3+DF) enhances the physical properties of fuel.

Also, the adding of (Al2O3) reduce CO emissions by 20.

5%, decrease NOxemission by 12.

2%, increasing CO2 emissions by about 2.

27% anddecrease UHC emission about 13.

5%.

Furthermore, reduces the brakespecific fuel consumption by 14.

3%, decreasing the equivalence ratioby 14.

87% and improving the brake thermal efficiency by about 10.

89%
