SECTION 8
ENGINE OIL SYSTEM

V2500 Line and Base Maintenance Engine Oil System
Revision 4 Page 8-1
Engine Oil System Introduction
Purpose
The oil system is a self-contained, full flow recirculating type designed to ensure reliable lubrication, cooling and vibration suppression under all operating conditions.
Description
Oil cooling is controlled by a dedicated Heat Management System, which ensures that engine oil, IDG oil and fuel temperatures are maintained at acceptable levels while ensuring the best cooling configuration for optimum engine performance.
The engine oil system can be divided into three sections:
 Pressure feed.
 Scavenge.
 Venting.
Pressure feed
The pressure feed system uses the full flow generated by the pressure pump. The pressure pump moves the oil through:
 The pressure filter.
 Air Cooled Oil Cooler (ACOC)
 Fuel Cooled Oil Cooler (FCOC).
The oil is then distributed to the engine bearings and gear drives.

Scavenge
The scavenge system is designed to retrieve the oil that is present in the bearing chambers and gearbox for cooling and recirculation.
There are six scavenge pumps that are designed to recover the oil and pass it through:
 Six magnetic chip detectors
 A scavenge filter and a master chip detector.
The oil is then returned to the oil tank.
Venting
The venting system is designed to allow the air and oil mix that develops in the bearing chambers and gearbox to go to the de-oiler where it is centrifuged to separate the oil from the air.
No: 4 bearing does not have a scavenge pump. It relies upon the build up of air pressure in the bearing chamber to force the air and oil through the No: 4 bearing scavenge valve and into the de-oiler.
Separate venting is not necessary for No: 5 bearing because with only one carbon seal, the airflow induced by the scavenge pump provides the required pressure drop across the seal.
Indications
There are flight deck indications that allow the oil system to be monitored.
There are also messages generated by ECAM for further flight crew awareness.
