Title: Exhaust cooling system for internal combustion engine

Abstract

A compact exhaust cooling system is described for an internal combustion engine consisting of: an exhaust manifold adapted to be mounted to the engine block of an internal combustion engine for receiving hot exhaust gases therefrom, the manifold having an integral manifold cooling jacket including coolant inlet means and a manifold outlet including one or more coolant discharge ports adjacent a gas discharge port; a duct terminating in a gas distribution header, the duct and header being double walled so as to define a continuous cooling jacket fully enveloping both the duct and header, the duct having an inlet end, the inlet end including coolant inlets into the second cooling jacket and a gas inlet to the duct, means for connecting the inlet end to the manifold outlet with the coolant and gas inlets in respective alignment with the coolant and gas outlets such that coolant from the manifold jacket flows through the continuous cooling jacket and returns to the engine through one or more coolant return ports in the header while engine exhaust gas flows from the manifold gas outlet into the duct gas inlet; a heat exchanger comprising a vessel having an upstream end, a downstream end andmore » gas tubes extending through the vessel between the ends, the tubes open at each end exteriorly to the vessel, the header being connected to the upstream end for supplying engine exhaust gas to the gas tubes, and means for circulating coolant through the interior of the vessel in heat exchanging contact with the gas tubes for cooling the exhaust gas passing through the gas tubes.« less
