The current study focuses on the influence of various boosting technologies as well as a comparative examination of single-cylinder four-stroke diesel engines. The experiment was conducted out on a single-cylinder 4-S VCR diesel engine with a crank-driven supercharger, turbocharger, and Tri-charged, which combines the turbocharger, crank-driven supercharger, and electric-driven supercharger system. Because the crank-driven supercharger uses engine power and the turbocharger has turbo-lag, the tri-charged system is used. The trials were carried out at a constant speed of 1500 rpm and a varied loading capacity of 0kg to 12kg at 2 kg intervals. The results increased the volumetric efficiency (VE) of the tri-charger from 81.17 to 122.35 percent. It is also raised in super and turbo running modes. Tri-charging lowered the BSFC from 0.36 Kg/Kwh to 0.31 Kg/Kwh, while thermal brake efficiency rose from 31.34 percent to 32.97 percent when compared to a traditional engine. The tri-charged method also helps to reduce pollution. The CO level dropped from 0.12 percent to 0.07 percent. NOX IS rises from 1015 ppm to 1210 ppm due to super, 1268 ppm due to turbocharger, and further lowered to 1128 ppm owing to super and turbocharger, although higher than conventional. This rise in NOx is caused by the increase in combustion temperature caused by the boost charger. Thus, the findings show that a tri-charged system is optimum for single-cylinder diesel engines in terms of performance enhancement and fulfilling rigorous emissions standards with emission reduction.
