| Abstract: | Exhaust gas recirculation （EGR） technique （：an reduce NOx emissions of diesel engine substantially. The potential reductions are especially significant in the case of cooled EGR and the efficiency of the EGR coolers is one of the most significant factors. The flow field of exhaust gas recirculation was simulated by the method of CFD numerical simulation. The simulation result can help the design and optimization of exhaust gas recirculation cooler which was used in a diesel engine. |
