ABSTRACT:
An engine comprises a pump adapted to communicate lubricating oil from the crank case thereof to a directional control valve. Upon engine start-up, the valve is conditioned to communicate oil through a filter and to a first manifold which, in turn, communicates with the crankshaft and rod bearings of the engine. Simultaneously therewith, cooled but unfiltered oil is communicated directly to bearings rotatably mounting a shaft in a turbocharger, mounted on the engine. After start-up, the valve will shift to further communicate unfiltered oil directly to a second manifold which, in turn, communicates with a plurality of jets for the purpose of cooling the pistons employed in the engine. The shifted valve will further function to permit communication of oil through the filter to the bearings of the turbocharger and to the crankshaft and rod bearings of the engine.
