Engine Lubrication: Description and Operation
The engine lubrication system is the force-feed type in which oil is supplied to these components:
* Crankshaft.
* Connecting rod.
* Valve tappets.
* Camshaft bearings.
From the valve tappets, a controlled volume of oil is supplied to the rocker arms through hollow push rods. All other moving parts are lubricated by gravity flow or splash.
The lubrication system consists of a full-pressure, cast-iron pump driven by the oil pump intermediate shaft from the camshaft synchronizer. The oil pressure is controlled by a relief valve.
The oil pan acts as a reservoir, holding the oil that is pumped through the engine by the oil pump after startup.
