Experimental analysis of performance and emission of a turbocharged diesel engine operated in dual-fuel mode fueled with bamboo leaf-generated gaseous and waste palm oil biodiesel/diesel fuel blends

Abstract

ABSTRACT In the present situation of emergencies of energy demand, rising oil cost, exhaustion of nonrenewable energy source assets. Biodiesel as well as producer gas acquired from vegetable oil, that is, waste palm cooking oil and biomass, that is, waste bamboo leaves are likely to be designated as the promising substitute fuel. Therefore, the goal of this research is to access the reduction in global warming gases mostly NOx and smoke associated with the introduction of producer gas along with waste cooking oil biodiesel. The current investigation draws out a test of preparing biodiesel from used waste palm cooking oil at different blending proportions and its application on a dual fuel mode turbocharged direct injection diesel engine, with varying load at a fixed speed of 1500 rpm. From the experimentation, it was seen that exhaust gas temperature and brake thermal efficiency reduced while, brake specific energy consumption increased by 10.81%↓, 14.08%↓, and 46%↑ relative to diesel fuel in single fuel mode. Taking into account the emission characteristics of smoke intensity, nitric oxide lowered by 63.59%↓, 91.71%↓but on the cost of higher hydrocarbon and carbon monoxide value of 40.63%↑ and 65.71%↑ in comparison to diesel mode when loaded to the maximum limit. Hence, it can eventually be concluded that waste palm cooking oil methyl ester blended biodiesel with bamboo leaf generated gaseous fuel can partially substitute existing diesel fuel with few engine alternations.
