3232820 - 1016E cylinder head/s - various operations

CONSTRUCTION FEATURES

The cylinder head is of the monolithic type, of aluminium-silicon alloy.The four valves per cylinder are mounted in their respective guides in V formation at about 47° and controlled by two camshafts via hydraulic tappets.A calibrated jet (1) fitted inside the cylinder head lubricates the high fuel pressure control coupling.

The space layout enables the combustion chambers to accommodate:

• the four valve heads;
• the spark plug hole;
• the injector hole;

with the advantage of improving the engine's thermal efficiency and reducing harmful exhaust emissions.The valve guides are installed by interference fit in their seats in the cylinder head.The inner diameter is finished off after assembly, using a specific reamer.The cylinder head gasket is metallic and there is no need to retighten the cylinder head at all during the life of the engine.
