Air Management System (AMS)
Air Flow
Air flows through the air cleaner assembly and enters
the low-pressure turbocharger.
The low-pressure
turbocharger increases the pressure, temperature,
and density of the intake air before it enters the
Interstage Cooler (ISC). Cooled compressed air flows
from the ISC into the high-pressure turbocharger. The
high-pressure turbocharger increases the intake air
pressure up to 345 kPa (50 psi). The hot compressed
air flows into the Charge Air Cooler (CAC) where it
is cooled, and then directed to the Engine Throttle
Valve (ETV) and mixing duct area of the throttle valve
assembly.
If the EGR control valve is open, exhaust gas passes
through the EGR system into the mixing duct where it
is mixed with the filtered intake air. This mixture flows
through the mixing duct into the intake manifold and
