The recycling system crankcase

-
The recycling system crankcase (PCV) has a valve mounted in the oil recycling crankcase gases separator (attached to the cylinder block) and two flexible. A hose connecting the PCV PCV valve to the intake manifold and the other connects the valve cover to the outlet pipe of the air filter.

At idle and part load, the vapors pass from the crankcase oil recycling gas separator housing, through the manifold and into the combustion chambers, where they are burned during combustion.

At full load, the crankcase gases pass from the cylinder head cover in the outlet pipe of the air filter, through the flexible PVC.

Outils spéciaux / Equipement d'atelier et outillage standard Kit de testeurs de bornes 29-011A Multimètre digital. Outil de diagnostic. Contrôle et vérification Note : Le module électronique générique (GEM) fait partie du boîtier électrique central (CJB). Note : Si le module GEM est remplacé, le module neuf doit être configuré après la pose. A cet effet, les données spécifiques au véhicule sont extraites du module à remplacer à l'aide de l'équipement de diagnostic et sont transférées dans le module neuf. Note : Avant d'extraire les données spécifiques au véhicule, s'assurer que toutes les connexions électriques du véhicule sont de nouveaux raccordées, de sorte que le module et l'outil de diagnostic puissent communiquer correct
