Effect of Exhaust Gas Recirculation on a CRDI Engine fuelled with Biodiesel, Ethanol and Butanol

The global community has focused on the sustainability of petroleum-based fuel supply due to increased usage in various sectors, depletion of petroleum resources, and volatile crude oil market prices. We are looking for alternative fuel. As a result, we have chosen biodiesel. In this paper, a diesel blend containing biodiesel, ethanol, and butanol was created to test the characteristics of a common rail direct injection (CRDI) diesel engine equipped with an exhaust gas recirculation (EGR) system. The blends of diesel-biodiesel and diesel-biodiesel-ethanol-butanol were designated as B40 and B40-E10-BUT10 respectively. The experiment is carried out at a rate of 20% EGR. The experimental results show that the mechanical efficiency is higher in biodiesel blends than in diesel. The use of an EGR system with these blends reduces NOx by lowering the oxygen concentration in the combustion chamber.
