ENGINE COMPONENT VIEW

The concept of modularity allows engine designs to share commonization between concepts and
engine hardware. The four modules are the:

intake module.

cylinder head module (RH).

cylinder head module (LH).

lower engine module.

The modular engine concept supports efficiencies during repairs by allowing the removal and
installation of these modules. While not all in-vehicle repairs can take advantage of the modular
concept, most out-of-vehicle repairs benefit in reduction of time and labor needed to repair the
engine.

The basic engine components consist of:

single overhead camshafts.

two valves per cylinder.

sequential multiport fuel injection (SFI).

aluminum cylinder heads.

cast iron, 90-degree V-cylinder block.

individual ignition coils for each spark plug.

on 4.6L engines, two-piece intake manifold system.

on 4.6L engines, composite-material lower intake manifold with noise insulator.

large-bore throttle body.
