Abstract:
1. An engine including a screw type supercharger having an outlet end cooling system comprising: an engine intake manifold providing a flow of compressed air into the engine; a screw type supercharger in fluid communication with the engine intake manifold providing the flow of compressed air into the intake manifold; an inlet end of the screw type supercharger receiving ambient air; an outlet end of the screw type supercharger opposite the inlet end of the screw type supercharger; a path for the ambient air from the inlet end of the screw type supercharger to the outlet end of the screw type supercharger with increasing pressure and temperature as the ambient air is compressed along the path to produce the flow of compressed air; a coolant to air heat exchanger for cooling a flow of coolant and having a heat exchanger coolant inlet and a heat exchanger coolant outlet; a first coolant line connecting the heat exchanger coolant outlet to a supercharger coolant inlet; a supercharger coolant path located at the outlet end of the supercharger, the coolant path to the outlet end of the supercharger receiving the coolant flow from the supercharger coolant inlet and wherein all of the supercharger coolant path is on the outlet end of the supercharger ahead of the supercharger housing; a supercharger coolant outlet receiving the coolant flow from the supercharger coolant path; and a second coolant line connecting the supercharger coolant outlet to the heat exchanger coolant inlet.
