VALVE VENTILATION VAPEUR HUILE S/COLLECTEUR "ORIGINE" CADMIEE

The crankcase ventilation system

Currently, despite the rapid development of technology, to create a completely sealed friction of the parts — the cylinder and the piston ring is not possible. Therefore, in the internal combustion engine over time during the operation of combustion products accumulate.In the sump of crankcase gases pass through the piston rings, which are adjacent to the cylinders loose. The result is worse than the heat is removed, reducing the lifetime lubricating fluid and formed excessive pressure on all block seals. The crankcase ventilation system prevents excessive crankcase pressure.



Development device

At the beginning of the mechanism is as follows: from the case just output tube, producing gases into the atmosphere and polluting it. But the norms for emission of gases from vehicles was seriously tightened. Therefore, the crankcase ventilation system had to be developed by manufacturers.



The Principle of operation of mechanism

In the form in which the system currently known, gases are not simply emitted into the atmosphere. They are sent to the motor by means of the derived tube from the crankcase, the other end of which is connected to the intake manifold. From there the gas is directed into the combustion chamber. At the time of the outbreak some of them burned and the other part is discharged through the exhaust mechanism. Only a small fraction of these gases back into the crankcase. So the process occurs without interruption.
