ABSTRACT:
A cooling system comprises at least one common feed manifold carrying a series of nozzles and forming a mechanically rigid assembly, with fixing means for fixing in the engine and with hydraulic connection means for making a hydraulic connection to a feed circuit in the engine. The mechanically rigid assembly is fixed into the engine block from the lower face thereof, the fixing lugs being fixed to easily accessible regions of the engine block before fitting the crankcase. The connection means are fixed into the crankcase and connected to the outlet of the oil filter by a common valve. An internal combustion engine piston cooling system may therefore be fitted without having to modify the structure of the engine block.
