Experimental investigation on performance, combustion and emission characteristics of nanoparticle blends with diesel as fuel in a CI Engine

Abstract

The present work has discussed the following characteristics like performance, combustion and emission characteristics of blends of aluminum (Al), zinc oxide (ZnO) and its mixture of nanoparticles at different ratios with diesel tested on a stationary direct injection compression ignition (CI) engine at five different loads. The fuels have been made by blending of nanoparticles with diesel at different concentrations. The results have shown that the Nano fuels have given lower brake specific fuel consumption (BSFC), higher brake thermal efficiency (BTE) and air-fuel ratio when compared with diesel. In combustion analysis, the Nano fuels have given higher heat release rate, crank angle 50 (CA50) and lower ignition delay when compared with diesel. In emission analysis, the Nano fuels have given higher nitrogen oxides (NOx) and lower carbon monoxide (CO), hydrocarbons (HC) and smoke emissions when compared with diesel. The fuel properties of nano fuels have shown that the kinematic viscosity, calorific values have been higher and flash point, fire point, density have been lower when compared with diesel.
