Air Intake System Description
| Air Intake System Description |
The primary function of the Air Intake System is to provide filtered air to the engine. The system uses a cleaner element mounted in a housing. The cleaner housing is remotely mounted and uses intake ducts to route the incoming air into the throttle body. The secondary function of the Air Intake System is to muffle air induction noise. This is achieved through the use of resonators attached to the air intake ducts. The resonators are tuned to the specific powertrain. The mass air flow (MAF)/intake air temperature (IAT) sensor is used to measure the temperature and the volume of the air entering the turbo.
A combined pressure/temperature sensor is located in the charge air pipe. The pressure is used by the ECM to control the turbo charger boost pressure. The temperature is used by ECM to request the right amount of air for the combustion (hot air requires a high volume).
