Abstract

A pressure washer system includes an engine block, a water conduit, a water pump, and a spray gun. The engine block is for a horizontally-shafted internal combustion engine, and has a chamber therein. The chamber is designed to contain oil for cooling and lubricating the internal combustion engine. The water conduit has a garden hose connector on an end thereof, and is fastened to the engine block. As such, heat transfers from the engine block to a flow of water passing through the water conduit during operation of the internal combustion engine. The water pump is coupled to the water conduit, where the flow of water is driven by the water pump. The spray gun is coupled to the water pump, where the flow of water exits the pressure washer system via the spray gun.
