Intake Manifold: Description and Operation
The air intake manifold is a two piece aluminum casting. Runner lengths are tuned to optimize engine torque and power output. The manifold provides mounting flanges for the air throttle body assembly, fuel supply manifold and accelerator control brackets as well as the EGR valve and supply tube. Vacuum taps are included to support various engine accessories. 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.
