Engine Component View: Notes

The concept of modularity allows engine designs to share commonization 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 throttle body
