Performance and Emission Study on Diesel Engine using Waste Cooking Oil with Methanol as Additive
Main Article Content
Abstract
As the years are passing by, the number of vehicles used for transportation is increasing. Due to this the environment is degrading and also the fossil fuels are depleting. This paper presents the performance and emission study on diesel engine using waste cooking oil with methanol as additive in various proportions. The properties such as the flash point, fire point, kinematic viscosity and the calorific values of the blends with and without additive are determined. Then all the biodiesel blends are used as fuel separately in the diesel engine. The engine performance as well as emission characteristics have been determined and compared at different blends. The blends with additive showed better properties and reduction in emission characteristics compared to diesel. The emission of CO is decreasing with increasing waste cooking oil and methanol quantity in the blends. Fuel consumption was more for the higher percentage blends with respect to increasing brake power. The emission of un-burnt hydrocarbon and oxides of nitrogen are reduced significantly with addition of methanol to fuel mixture due to higher oxygen and heat of vaporization.
