Experimental Investigation of the Effect of Exhaust Gas Recirculation on Performance and Emissions Characteristics of a Diesel Engine Fueled with Biodiesel

A. Paykani, A. Akbarzadeh and M. T. Shervani Tabar

Abstract—An effort has been taken to study performance and emission characteristics of a diesel engine fueled with biodiesel and diesel fuel using EGR. All the experiments were conducted on a single-cylinder, four-stroke, water cooled, indirect injection (Lister 8-1) diesel engine at the engine full load operation and constant engine speed of 730 rpm. The results obtained with biodiesel (canola oil ethyl ester) were compared with the diesel fuel as reference fuel. The engine performance and efficiency obtained in biodiesel case were less, which could be attributed to lower calorific value of biodiesel. CO and UHC emissions for biodiesel were lower than that of diesel fuel. However, it was observed that NOx emissions for biodiesel were higher than that of diesel fuel. Exhaust gas recirculation (EGR) is a very effective technique to reduce NOx emissions from a diesel engine. In this study the venturi type EGR system was used. When similar percentages (%by volume) of exhaust gas recirculation (EGR) were used in the cases of diesel and canola oil ethyl ester, NOx emissions were considerably reduced to lower values.

Index Terms—Canola oil ethyl ester; Biodiesel; Diesel engine performance; Exhaust emissions; Exhaust Gas Recirculation (EGR).
