Case ventilation

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

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