Performance and Emission of a Single Cylinder Stationary Diesel Engine with Exhaust Gas Recirculation

In today's modern world the internal combustion engine has a predominant role in stationary low power generation and a virtual monopoly in mobile applications. Concentrations emitted from the internal combustion engines thus build up to levels sufficient to have adverse effects on plants and animals. From the literature we find that any technique employed to mitigate emissions has adverse effect on the performance. EGR is considered as a most efficient method to reduce the NOx exhausted. This method is employed to a single cylinder naturally aspirated DI diesel engine. The test is carried for different injection pressures and percentage of exhaust gas recirculation. Its effect on engine performance except for the smoke measurement is presented in this paper. There is a remarkable reduction in the NOx concentration but a marginal reduction in brake power and thermal efficiency are also observed.
