Description
The air is sucked through a foam air cleaner. The air enters the air cleaner housing at the bottom and
leaves at the top.
The air cleaner is made up of 5 different layers of foam. Each layer is having different cleaning
efficiency.
After filtration the air goes to the turbocharger.
A HFM sensor is attached to the outlet of the air cleaner. The air to the turbocharger has to go
through the HFM. The HFM measures the air mass going to the engine. The quantity of the air going is
used to compute the fuelling.
After the HFM and before turbocharger there is mechanical or electrical service indicator. In case of
electrical service indicator, signal of choked air cleaner goes to the instrument cluster. In case of
mechanical one, red band appears in choked condition.
The waste gated turbocharger controls the boost to 1.6. The compressed air is cooled by the charge
intercooler, which is mounted just below the radiator. The cooled air enters the inlet manifolds. It
enters the Cast iron cylinder head through the inlet valves having a 45-degree angle.
