PERFORMANCE AND EMISSION CHARACTERISTICS OF DIESEL ENGINE WITH EGR FOR VARIOUS BIODIESEL BLENDS: A REVIEW

Abstract

Nowadays, Internal Combustion engines are the essential parts of transportation and mechanized agricultural system. So the consumption of diesel and petroleum has been upsurged. As petroleum is a nonrenewable source and recent surge in petroleum prices have regenerated interest in bio-fuels. In this present work, study has been carried out to find effect of biodiesel blends on Engine performance with Exhaust Gas Recirculation (EGR). Most of the researchers have reported that biodiesel-fueled engines produce less CO, unburned HC and smoke emissions compared to diesel fuel, but higher NOx emissions. The literature shows that, Exhaust Gas Recirculation (EGR) is an efficient technique to reduce NOx emission as it lowers the flame temperature in the combustion chamber with higher fuel consumption.
