Effect of Tri-Charged Boosting on Single Cylinder Four Stroke Diesel Engine at Different Compassion Ratio

Abstract

The paper presents the effects of crank driven supercharger, turbocharger and electric supercharger called a Tricharger on a single-cylinder four-stroke diesel engine. Because the supercharger burns output power and the turbocharger has
turbo-lag, the tri-charged system is designed to alleviate the drawbacks of both the supercharger and the turbocharger. The
testing were carried out on a 1500 rpm constant-speed engine with varied load and compression ratios. The load increases
from 0 to 12 kg in 2 kg increments, with a compression ratio of 16 to 20. The results show a considerable gain in volumetric
efficiency as a result of super, turbo, and tri-charged boost air. Thermal efficiency, on the other hand, decreases at low and part
load owing to super and turbocharger for all compression ratios. Furthermore, when operating at half and full load capacity, the
engine equipped with a tri-charged boost enhanced thermal efficiency by 0.41 and 0.78 percent, respectively. The impact of tricharging on engine emissions, CO, HC, and NOX is decreased by 0.38, 0.73, and 0.53 percent, respectively, for CR18. As a result,
the tri-charger may be applied to a single-cylinder diesel engine without requiring any design changes, and engine performance
and pollution criteria can be met.
