Abstract

The paper presents an experimental investigation and comparative analysis on the effects of crank driven supercharger, exhaust-driven turbocharger and Tri-charged (C-Super + E- Super with One Turbo) system on a single-cylinder four-stroke diesel engine. Manufacturers generally adopt single charged boosting systems due to challenges associated withachieving appropriate tuning, compatibility, and controllability of multi-charger boosting systems.In earlier works, experimental trials were conductedeither on supercharger alone,turbocharger, or twin- charger on multi-cylinder engines.The drawback of a supercharger is that it consumes output power and the problem witha turbocharger is it has turbo-lag. The single-cylinder small capacity engine produces uneven power and cost isa significantfactor. Thus tri-charged single-cylinder enginehasan advantage intermsof power, efficiency and economy. In the present work, experimental trials were conducted at a constant speed of1500 rpm and variable loading capacity of 0kg, 2kg, 4kg, 6kg, 8kg, 10kg, and 12kg.The results showed that there is a significant improvement in volumetric efficiency using the tri-charged system,which is 60.08 %, compared  to 18.04 % with conventional and supercharger, and 45.72 % with a turbocharger,  when  operating at full load. Brake thermal efficiency improved by 1.34%, 1.08%, 0.22% due to tri,  turbo and supercharging. The tri-charged system is also beneficial to reduce emissions.CO  reduced from 0.11 % to 0.08 % by volume., HC from 39 to 31 ppm, CO2 from 5.90 to 4.9 % by volume. O2 increased from 12.42 % to 13.83 % and NOx reduced from 1336 ppm to 1040 ppm. The use of a tri-charged boosting systemresulted in a slight increase in fuel consumption.
