Ventilation of the engine

Ventilation of the engine is necessary that in the case of a bent shaft there was no harmful excessive pressure.

As piston rings cannot carry out rather densely sealing, hot gases get into a case of a bent shaft. Mix of hot oil and vapors of fuel can create the excessive pressure which harmfully influences the krivoshipno-conrod mechanism. In order to avoid it gases have to be sucked away through a connecting hose from the engine and be burned.

The closed ventilation of the engine does not demand maintenance.
