Engine: Description and Operation

Engine Identification


The concept of modularity allows engine designs to share communization 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° V-cylinder block.
^ two-piece intake manifold system.
^ composite-material lower intake manifold with noise insulator.
^ Large-bore throttle body.
