Turbo supercharger acts as lungs in a CI engine. They enhance the performance of a CI engine by pushing in more air into the cylinder which leads to complete burning of the fuel thus delivering more power to weight ratio.
This work deals with the performance of turbo supercharger used in Locomotives. This includes the role played by the turbo chargers in increasing the mean effective pressure which in turn leads to greater power to weight ratio being developed by the engine. This on the other hand leads to an effect of increasing the peak temperature of the inlet air into the cylinders.
