Abstract
The objective of this paper is to prepare Diesel like fuel (DLF) from waste lubrication oil and to study the analysis of the performance and emission characteristics of the diesel like fuel and comparing with petroleum diesel. The tests were carried out on a 3.7kW Four stroke single cylinder, direct injection, Air-cooled diesel engine. The fuel properties of diesel like fuel from 20 to 100% by volume are studied by using results. Engine tests have been carried out with the aim of obtaining comparative measures of Brake power, specific fuel consumption and emissions such as CO2, CO, HC and NOx to evaluate and compute the behavior of the diesel engine.
A minor decrease in thermal efficiency for 20% blend (DLF) when compared with petroleum diesel with significant improvement in reduction of carbon monoxide and hydrocarbons is observed compared to diesel. The experimental result shows that 20% of blend shows better performance with reduced pollution.
