Experimental Investigation on the Performance and Emission Characteristics of Di-Diesel Engine Using Diesel- Ethanol Blends and Aluminium Oxide Nano Particles

An experimental investigation was carried out to evaluate the performance and emission characteristics of four stroke, single cylinder, constant speed diesel engine using aluminium oxide nano particles as additive in diesel ethanol blends compared with neat diesel. N-butanol (normal butanol) is used to prevent the phase separation between diesel and ethanol. 30nm sized aluminium oxide nano particle additives are used in every diesel and ethanol blends in the mass fraction of 50ppm.Final results are showing that the brake thermal efficiencies of the engine using diesel ethanol with nano additive blends are increased at higher loads compared to neat diesel and diesel-ethanol blends. Specific fuel consumption was slightly increased in diesel–ethanol blends compared to neat diesel due to lower heating value of ethanol. Emissions also controlled by using diesel, ethanol with nano additive blends compared to dieselethanol blends.
