Description And Operation
The air intake system consists of the following components:
- Air Duct
- Air Filter Cold Air Intake Tube
- Air Cleaner Body
- Turbocharger Air Intake Tube
- Turbocharger
- Surge Valve
- Air Outlet Pipe From Turbocharger To Throttle Body
- Intercooler built into the Intake Manifold
The engine intake air is delivered to the air filter located between the engine and the cooling system module (radiators). From the air filter outlet, air enters the turbocharger inlet through the intake tube. The turbocharger compresses the air and sends it under higher pressure to the throttle body through a rigid plastic tube.
The air filter is located in the plastic air cleaner body. The top is closed by a cover, also made of plastic.
The plastic cover is fastened to the lower body by interlocking tabs and four screws.
The intercooler is built into the intake manifold. Heat is removed from the air entering the intercooler by low-temperature water that is circulated within by a dedicated cooling system through the coolant inlet and outlet ports (1).
The intercooler is inside the intake manifold "box" and is fastened to the manifold with screws.
The airflow from the turbocharger is controlled by the throttle body and enters the bottom of the intake manifold. Once inside the manifold, the air gives off heat as it passes through the intercooler plates, which are maintained at a lower temperature by the coolant circulating within. This lower temperature air mixes with the idling engine oil vapor inlet (1) and exits from the manifold to enter the cylinder head intake ports.
