Intake air

Intake air
If the intake line is located close to exhaust pipes or other hot parts, radiation protection should be used to limit unnecessary heating of the intake air.
REQUIREMENT!
The intake air temperature upstream of the turbocharger must be below 30°C.
Measure the temperature when the installation is complete. Refer to 02:08 Measur-
ing instructions for installation inspection.
If the intake air temperature upstream of the turbocharger continuously exceeds
30°C, then engine power may drop. If the engine is enclosed in some manner, make
sure that there is an adequate flow of intake air.
The dependence of the engine power on intake air temperature is shown in the chart
on the right. 100% engine power is shown under actual test conditions at the factory.
The engine air consumption in kg/min at full power and at different engine speeds is
indicated in the tables showing the air consumption and radiated heat for the relevant
engine type in 02:06 Technical data.

Intake air
02:02 Issue 4.0 en-GB 5
Intake air taken from outside engine room
In engine systems where the engine intake air comes from outside the engine room
and is led via a fresh air line to the engine, the vacuum for the intake system should
be measured.
The air intake should be located so that the intake air is as clean as possible and so
that neither the engine exhaust gases nor heated air from the engine room can mix
with the intake air. The air intake should be designed to exclude water, snow and contamination.
The intake air must not contain chemical pollutants, such as CFCs.
REQUIREMENT!
The maximum permissible vacuum in the intake system is 30 mbar. This value includes the vacuum in the new air filter, connected coarse filter and in the fresh air
line.
Measure the vacuum when the installation is complete. Refer to 02:08 Measuring in-
structions for installation inspection.
