TL;DRAbstract

A supercharging system comprising of a mechanical supercharger and a turbo charger was investigated with experimental and numerical analysis in a diesel engine for use in a commercial vehicle. The frictional losses of the mechanical supercharger were reduced by putting it together with a turbo charger. Furthermore, it was found that the fuel consumption of the vehicle could be improved by optimizing power train specifications. This was accomplished due to the increased low-end torque which was enabled by a mechanical supercharger.
