Abstract: A method for repairing the cylinder block of an internal combustion engine. The cylinder block engages a standard cylinder head and includes an outer cylinder casting that surrounds an inner cylinder sleeve. The casting has corrosion formed in an end surface that faces the cylinder head. The method includes the steps of providing a repair ring that is separate and distinct from the cylinder sleeve and has a selected thickness. A counterbore is formed in the end surface of the cylinder casting to remove the corrosion therefrom. The counterbore has a depth that is no greater than the thickness of the ring. The ring is installed annularly about and in close tolerance fit with the cylinder sleeve and is introduced into the counterbore. At least one of the cylinder sleeve and the ring are machined for form thereon respective, generally co-planar surfaces that face the cylinder head.

Abstract: An auxiliary power system for an air conditioner and heater of a vehicle includes an auxiliary motor which is selectively connected by an electromagnetic clutch of a jack shaft assembly to drive the compressor of the vehicle's air conditioner. The jack shaft assembly reduces the RPM of the auxiliary motor to an RPM suitable for operating the compressor. The auxiliary engine has a cooling system and an exhaust system which are respectively connected to the cooling and exhaust systems of the vehicle's main engine. A baffle plate is provided at the point of connection to direct the flow of exhaust gases from the auxiliary engine into the exhaust system of the main engine. Solenoid actuated valves circulate coolant fluid from either the auxiliary or main engine to selectively heat water in a tank or to heat the interior of the passenger compartment of the vehicle. An auxiliary fan cools the condenser and radiator of the vehicle when the auxiliary engine is operating.
