NOTE

Pressurizing the inlet air causes the air to heat up.

The low pressure turbocharger (2) compresses the air.

NOTE

•

The high pressure turbocharger is used to compress the air to a

higher pressure.

•

This increase in pressure continues to cause the inlet air's

temperature to increase.

Pressurized air exits the low pressure turbocharger (2) through an outlet (3) and the air is

forced into the inlet (4) of high pressure turbocharger (5).

NOTE

•

The precooler uses engine coolant to cool the air.

•

Without the precooler, the inlet air would be too hot in order to be

cooled sufficiently by the aftercooler

As the air is compressed, the air is forced through the high pressure turbocharger's outlet

(6) and into the precooler (7).
