Engine: Description and Operation

Modular Engine - Typical:

The concept of modularity allows engine designs to share communization between concepts and engine hardware. The illustration (modular engine-typical) represents the basic cross sectional view of a modular V8 engine. 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.
- Two-piece intake manifold system.
- Composite-material lower intake manifold.
- with noise insulator.
- Large-bore throttle body.
