Abstract:-
The impacts of a Twin-charged (turbo + super) technology on a single-cylinder four-stroke diesel engine were explored in this experimental investigation under various operating situations. Because the supercharger burns output power and the turbocharger has turbo-lag, we conducted an experimental investigation on the twin-charged system in this research to solve the drawbacks of both the super and turbocharger. The experiments were carried out on a constant speed engine of 1500 rpm with varied load and compression ratio. The load varies from 0 to 12 kg in 2 kilogramme increments, with a compression ratio of 12-18. The results show that super, turbocharged boost air improves volumetric efficiency significantly, however super and turbocharger diminish thermal efficiency at low and part load for all compression ratios. Furthermore, the engine was updated with a twin-charged (turbo + super) boost to improve thermal efficiency. Tri-charging has a positive impact on engine emissions, lowering CO, HC, and NOX. However, managing the combustion phasing, expanding the operating range, and reducing unburned hydrocarbon and CO emissions remain difficult difficulties in the successful operation of HCCI engines. Massive global research has resulted in significant advances in the control of HCCI combustion.
