Abstract:
An internal combustion engine having a cooling-air blower such as an axial flow fan having a mounting bolt mounted directly on the cylinder head of the engine and a housing, preferably formed in two shell-halves connected together and mounted on the engine by screws or the like which already exist on the engine. The shell-halves form cooling-air passageways by the engine for air from the blower.
Abstract:
An engine of a motor vehicle has a passage for the flow of fresh cooling air in heat exchange relation with the engine, the passage being closed and isolated from a joint between the engine block and the cylinder head to preclude entry into the passage of gases leaking past the joint. The passage leads to a passenger compartment of the vehicle for heating the interior thereof.
