Exhaust ventilation of a case

The engine passes 50–70 liters of exhaust gases a minute through piston rings in a case. Pressure which should have an exit from the engine is created not to overstrain laying. Poisonous gases not to harm to environment, from the engine come back to canals of absorption or in soaking-up collector. From there gases are once again soaked up by the engine for complete combustion.

 Council: If the engine too intensively blows pairs of oil in exhaust ventilation of a case, it testifies to already considerable wear of pistons and cylinders.
