Lubrication (page 2 of 2)

From the main longitudinal duct in the crankcase, a vertical duct branches off which lubricates the camshaft bearings. On the intake side of the camshaft lubricating duct there are two special channels through which the oil for operating the timing variator passes. The recovery circuit is formed of a few ducts located in the cylinder head which collect the oil leading from the outlets and then drain it from the head from which it falls back into the sump.

The lubricating system is fitted with an oil vapour recirculation system which recovers the vapours leading from the sump and from the cylinder head.

The system is fitted with a minimum engine oil pressure sensor (7) which indicates insufficient lubricating pressure by turning on the warning light on the instrument cluster.
