The basis of the work of the recirculation system on four-stroke engine is located on a difference in the way the oil is stored in the machine.
There are two systems:
1, System Oil Dry Place (Dry-Sump System)
Accommodated in a separate oil tank and oil pump pressure supplied through the same channel in a wet sump system. After lubricating oil back into the crankcase and routed back to the tank by the pump. Clutch and transmission is lubricated by splashing oil from the oil tank to the pump.
2 The System Oil Wet (Wet sump system)
Lubricating oil are placed in the space below the crankcase oil, rose oil from the room and given under pressure. Most of the oil supplied to the crankshaft and partly to the valve actuator. Most of the oil in the crankcase lubricant is used to lubricate the cylinder walls. Oil lubricates the cylinder piston and piston rings and excess oil swept down by the ring and then back into the crankcase. Clutch and trasmisi lubricated by splashing oil from the oil pan or oil pump pressure.
Wet sump system advantages:
a. Very simple construction purposes
b. Heat the engine is not too long.
c. If the oil in the vessel is reduced easily extended.
d. Faster oil circulation and quick washing.
e. Efficiensi cooling lower.

2, Inlet camshaft 5, Bypass valve, 8, Oi, l pump,
3, Exhaust camshaft, 6 Pressure relief valve, 9, Sump (oil pan),
The bottom of the crankcase oil is pumped up by the pump system Trochoid with tap and filtered by the filter before it is introduced to all the components that need lubrication.
