Engine Component View

The concept of modularity allows engine designs to share concepts and hardware. The following illustration represents the basic cross-sectional view of a modular V10 engine. The four modules are:

• Intake module
• Cylinder head module (RH)
• Cylinder head module (LH)
• Lower engine module

Due to the modular design, most out-of-vehicle repairs benefit in reduction of time and labor needed to repair the engine.

Bi-fuel vehicles differ from gasoline vehicles through the addition of hardened valves and valve seats.

The basic engine components consist of:

• Single overhead camshafts
• Two valves per cylinder
• Balance shaft
• Sequential multiport fuel injection (SFI)
• Aluminum cylinder heads
• Cast-iron, 90-degree V-cylinder block
• Individual ignition coils for each spark plug
• Two-piece intake manifold system
• Composite-material lower intake manifold
• Large-bore throttle body
