3.4 CHECKING EXHAUST GAS BACK PRESSURE
Checking exhaust gas back pressure
1. Remove the plug from the exhaust elbow
attachment or bore a hole and install a
suitable coupling with a pipe. The first part of
the pipe must be made of metal, to withstand
the high temperatures.
Note:
Use an attenuated gauge to prevent
excessive shaking of the gauge needle.
2. Connect a pressure gauge to the pipe, with a
range of at least 0.1 - 0.2 bar (10 - 20 kPa).
Note:
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
measurements to the specified value. See
"Technical data". Check the exhaust system
if the exhaust gas back pressure is too high.
4. Remove the pressure gauge and the
coupling and fit the plug.
