Optimization Of Performance Parameters Of A Super-Turbocharged Single Cylinder Four Stroke Diesel Engine Using A Taguchi Approach

Abstract

One of the major concerns worldwide is related with eventual depletion of fossil fuels, growing ambient pollution and global warming hazards occurring on regular basis. The Internal combustion engine used for transportation and agriculture purpose consume more fossil fuels and emit significant amounts of atmospheric pollutants. Hence there is need to have complete combustion of fuel with less emissions, the super-turbocharged system is the best option to optimize the performance of diesel engine. In this paper, an attempt has been made to optimise the performance of super-turbocharged engine in comparison with conventional engine. The various parameters such as Load (W) varies from 0 to 12 kg , Mass fuel consumption (Mf) varies from 0.332 to 1.22 Kg/Kw h, Mass of air consumption (Hw) from 0.063 to 0.166 Kg/ h and Speed (N) maintained at 1500 rpm constant. Experiments have been performed under different conditions of load, fuel and air consumption. Taguchi’s L9 orthogonal array was used to investigate the optimum performance of using super-turbocharged technology. It has been found that the volumetric efficiency increase from 88.29 % to 107.64 using supercharged and combined super-turbocharged technology and to 119.74 %. The experimental results indicate that multiple response characteristics such as volumetric and thermal efficiency can be improved effectively through the relational analysis and significant parameter was determined by analysis of variance.
