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
process is known as exhaust gas recirculation (EGR) and is one of the principal methods used to reduce nitrogen drive systems. MTU has produced a very com- pact design that permits all the exhaust gas recirculation components to be integrated into the engine concept (see Figure 1), so that any Principle of operation.

It is added either at the exhaust manifold or at the intake air system, or it is located in a heat- resistant exhaust-gas pipe

17 Oct 2015 In modern turbocharged engines it can be problematic to provide the amount of EGR that is needed to reach the emission limits. Other concerns can be the transient response of both the EGR-system and the engine. This work provides a simulative comparison of different EGRsystems,such as long-route
