Engine: Description and Operation: Description and Operation
EngineThe 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
