Technical characteristics



Exhaust ventilation картера

The engine passes 50–70 litres of the fulfilled gases a minute through piston rings in картер. Pressure which should have an exit from the engine is created not to overstrain a lining. Poisonous gases not to harm to environment, from the engine come back in channels всасывания or in soaking up collector. Therefrom gases are once again soaked up by the engine for full combustion.

 Council: If the engine too intensively blows oil steams in exhaust ventilation картера, it testifies to already considerable deterioration of pistons and cylinders.
