Ventilation картера

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

 The help: if in ventilation картера the engine throws out an appreciable smell of oil, it speaks about considerable deterioration of pistons and cylinders.
