Abstract

An arrangement for driving the oil and water pumps of an internal combustion engine in which the pumps are driven independently of the engine's speed. In one arrangement the oil pump is activated prior to starting the engine to provide adequate lubrication to the engine during the starting operation. The activation of the water pump may be controlled by the temperature of the engine such that it is not needlessly driven when the engine is cold.
