Thermostatic Air Cleaner: Description and Operation
OPERATION
The air cleaner is open to ambient air. The blend door and vacuum motor used in previous model years to supply heated air is no longer used. The
air cleaner housing assembly contains an air filter.
The Engine Controller monitors air temperature in the intake manifold through the Charge Air Temperature sensor. The controller adjusts injector
pulse width and ignition timing to compensate for intake air temperature.
