Design of exhaust gas recirculation system (EGR) for diesel engine

The exhaust from vehicles pollutes the environment and contributes to global warming, acid rain, smog, odors, respiratory and other health problem.

Astronautics The exhaust from vehicles pollutes the environment and contributes to global warming, acid rain, smog, odors, respiratory and other health problem. This thesis aims to design a novel system of exhaust gas recirculation (EGR) system for diesel engine. A full system of EGR was built based on the design to reduce the exhaust temperature back to the combustion chamber in order to reduce the NOx emission. The new technique design consists of pipe, heat exchanger, valve and flow meter. The experiment used a diesel engine Mitsubishi 4D68 operated with diesel fuel and PME100 fuel. A gas analyzer was used to measure the emission level on the diesel engine. The experiment was conducted to identify the effect of the quantity of NOx emissions in diesel engine using EGR, new EGR and without EGR. The results of the emissions level on exhaust gas using EGR, new EGR and without EGR are compared. Result shows that NOx emission level using EGR is lower than using new EGR and without EGR. This is because the exhaust temperature is low when using EGR. The NOx concentration was reduced due to the decreasing exhaust temperature. The new EGR did not reduce enough exhaust temperature compared to the original EGR. However, compared to not using EGR, the new EGR still reduced the NOx emission. Finally, the study conforms to its objective where it provides a new and effective technique of EGR that reduces the NOx concentration in diesel exhaust. This study is conducted in order to design a new heat exchanger and a more effective cooling system made with different materials. The experiment was conducted using various type of fuel at difference engine RPM and engine loading. 2012-06 Undergraduates Project Papers NonPeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/4641/1/cd6596_103.pdf Syahmi, Ahmad Ramly (2012) Design of exhaust gas recirculation system (EGR) for diesel engine.
