Title (EN) CRANKCASE VENTILATION SYSTEM WITH ENGINE DRIVEN PUMPED SCAVENGED OIL
(FR) SYSTÈME DE VENTILATION DE CARTER DE MOTEUR AVEC HUILE DE RÉCUPÉRATION POMPÉE ENTRAÎNÉE PAR MOTEUR
Abstract:
(EN) A crankcase ventilation system for an internal combustion engine has an engine driven pump pumping scavenged separated oil from the oil outlet of an air- oil separator to the crankcase, preferably using engine generated pulsating oscillatory positive and negative relative pressure pulses.
(FR) L'invention concerne un système de ventilation de carter pour un moteur à combustion interne, qui comprend une pompe entraînée par moteur pompant une huile de récupération séparée de la sortie d'huile d'un séparateur air/huile vers le carter, de préférence au moyen d'impulsions de pression relatives positives et négatives oscillatoires pulsatiles générées par moteur.
