3.2 CHECKING EXHAUST GAS BACK PRESSURE
Checking exhaust gas back pressure
1. Remove the plug from the exhaust bracket
and install a suitable coupling with a pipe.
The first part of the pipe must be made of
metal, to withstand the high temperatures.
2. Connect a pressure gauge to the pipe, with a
range of at least 0.1 - 0.2 bar (10 - 20 kPa).
Note:
Use an attenuated gauge to prevent
excessive shaking of the gauge needle.
The engine brake must not be used during
measurements.
This is to protect the pressure gauge.
3. Measure the exhaust gas back pressure at
full-load engine speed and compare the
measurement to the specified value; see
"Technical data".
