Description And Operation: Engine

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
• Individual ignition coils for each spark plug
• Composite-material lower intake manifold with noise insulator
• Large-bore coolant heated throttle body
