Technical characteristics


Exhaust ventilation of a case

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

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