The Performance of Exhaust Gas Recirculation (EGR) on a Single-Cylinder Diesel Engine Fueled B10 Biodiesel and Diesel

Mohamed Hussin Abdullah Altaher


Abstract: Increasing global population in present years means more vehicle ownership which leads to the increasing of oxides of nitrogen (NOx) and greenhouse gas emission. Oxides of nitrogen (NOx) are produced from the fuels which burned at high temperatures; contributes to the formation of ozone smog, harmful unseen particles, acid rain, and oxygen depletion that reduced the water quality. The use of higher oxygenated nature biodiesel as an alternative fuel also contributes to the increasing formation levels of NOx emission. In respond to the matters arise, exhaust gas recirculation (EGR) has been introduced to control NOx emissions from diesel engines effectively which lower the oxygen concentration in the combustion chamber. Experiments will carry out by implementing EGR consisting a non-insulated stainless steel pipe together with an industrial grade ball valve on a 219 cc single cylinder four- stroke Yanmar L48N diesel engine. An effort has been taken to study the 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. Palm-biodiesel blends will use as a baseline fuel. The objective is to understand the effect of EGR on diesel engine performance and emissions levels of NO in particular, C0, C02, and HC contained in exhaust gas. The engine will operate at an increasing engine speed from 1200rpm up to 3000rpm and significant data such as power, torque and exhaust gas emission levels its record at various EGR loads. The EGR flow rate will be regulated using the ball valve. The results obtained with biodiesel (B10) 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 the 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. Objective of this research paper is the fabricate the EGR line for single cylinder diesel engine, engine performance (power and torque) for the different EGR opening and investigate the effect of Exhaust Gas Recirculation (EGR) on the emissions levels of palm-biodiesel B10 and diesel.
