Ventilation of a case

Even the serviceable engine throws out through piston rings in a case 50–70 l of the fulfilled gases a minute. This pressure has to leave an engine case not to overload sealing laying. It occurs by means of ventilation of a case. Poisonous gases from engine interiors for environment protection come back once again to inlet channels or to the case of the air filter. From there they for full combustion are once again soaked up by the engine.

 Help: if in ventilation of a case the engine throws out a noticeable smell of oil, it speaks about considerable wear of pistons and cylinders.
