Experimental Investigations on 4-Stroke Single Cylinder Diesel Engine with Diesel-Butanol Blends and Tetra Nitro Methane as Additive

Abstract

The main concern of any automobile is to improve efficiency and reduce emissions. The depletion of Fossil Fuels has posed an alarming consequence for the field of Automobile engineering. To reduce emissions and increase efficiency, Butanol is adopted as an alternative fuel and tetra nitro methane (TNM) as an additive. The experiments were carried out on a 4-stroke single-cylinder diesel engine 5Hp rated power at different loads. The performance parameters like brake power, total fuel consumption, brake thermal efficiency and the emissions CO, CO2, HC and NOx are measured carefully. Among all the blends, 70%D-30%B has shown a more interesting change in thermal efficiency and emissions. At this proportion, TNM was added as an additive in different proportions. All the performance parameters were calculated, and emissions were measured at all proportions of TNM. There was a further increase in thermal efficiency and a reduction in emissions when the TNM was added. The higher thermal efficiency was achieved at a 70%D-30%B-15%TNM proportion with lower emissions when compared to diesel alone.
