Intake Air System - General Informa-

tion

The intake air system consists of intake air piping, turbo-

charger, charge air cooler (CAC) piping, and CAC.

The turbocharger uses exhaust gas energy to turn the

turbine wheel. The turbine wheel drives the compressor

impeller which provides pressurized air to the engine for

combustion. The additional air provided by the turbo-

charger allows more fuel to be injected to increase the

power output from the engine.

NOTE: The correct turbocharger must be used. Providing

too much additional air will increase the cylinder pressures

and shorten the life of the engine.

The turbine and compressor wheels and the shaft are

supported by two rotating bearings in the bearing hous-

ing. Passages in the bearing housing direct filtered, pres-

surized engine oil to the shaft bearings and thrust bear-

ings. The oil is used to lubricate and cool the rotating

components to provide for smooth operation. The oil then

drains from the bearing housing to the engine sump

through the oil drain line.

NOTE: An adequate supply of good, filtered oil is very im-

portant to the life of the turbocharger.

As the intake air is compressed by the turbocharger, the

air is heated. This heated air is then passed through the

charge air cooler which cools the air. Because cool air is

more dense than warm air, more air can be compressed

into the cylinder, yielding a much greater combustion

efficiency.
