Performance prediction of single cylinder four stroke Tri-charged diesel engine using Taguchi approach

Abstract

The ultimate depletion of fossil resources, rising ambient pollution, and frequent global warming threats are major worries throughout the world. Internal combustion engines used in transportation and agriculture consume more fossil fuels and release considerable amounts of pollution into the atmosphere. As a result, there is a requirement to complete fuel combustion while emitting less pollutants; the super-turbocharged system is the greatest alternative for optimising diesel engine performance. This research seeks to maximise the performance of a tri-charged engine in comparison to a regular engine. Load (W) fluctuates from 2 to 12 kg, Mass fuel consumption (Mf) ranges from 0.332 to 1.22 kg/kW h, Mass of air consumption (Hw) varies from 0.063 to 0.166 kg/h, and Speed (N) remains constant at 1500 rpm. Experiments were carried out under various load, fuel, and air consumption situations. The optimal performance of tri-charged technology was investigated using Taguchi's L9 orthogonal array. The volumetric efficiency rises from 88.29% to 107.64% when supercharged and combined super-turbocharged technology is used and to 119.74 percent when supercharged and combined super-turbocharged technology is used. The current study proposes the ideal engine operating settings to maximise engine efficiency.
