Intake Manifold: Description and Operation

Intake Manifold:

The intake manifold is a two-piece (upper and lower intake manifold) aluminum casting design. Runner lengths are tuned to optimize engine torque and power output. The manifold provides mounting flanges for the throttle body assembly, fuel supply manifold, accelerator control brackets, EGR valve, supply tube and Air Bypass Valve. Vacuum taps are provided to support various engine accessories and crankcase ventilation. Pockets for the fuel injectors are machined to prevent both air and fuel leakage. The pockets, in which the injectors are mounted, are placed to direct the injector fuel spray immediately in front of each engine intake valve.
