Ventilation Engine

The ventilation of the engine is required to the crankshaft in the housing did not arise harmful overpressure.

As the piston rings can not be tight enough to carry out sealing, hot gases enter the crankcase. The mixture of hot oil and fuel vapor can be pressurized, which adversely affects the crank mechanism. To avoid this gas must be sucked through the connecting hose from the engine and burned.

Closed ventilation motor requires no maintenance.
