Indication of the firing pressure
Use the following electronic indicator for gauging the pressure:
•
Lemag PREMET LS
This method is useful to determine changes in the firing pressure of individual cylinders. Indication
is always necessary if the assessment of the exhaust temperatures shows that there are changes in
individual cylinders. Even if irregularities cannot be discerned during the monitoring of the exhaust
temperatures, it is advisable to check the engine at regular intervals by means of indication.
Only perfect measuring instruments will make exact measurement results possible. The measuring
device must be, stored with care and the manufacturer's instructions observed.
•
Operating instructions for the indicator: refer to
.
•
Draw indicator diagrams at full load if possible.
•
Blow out the indicator valves so that no carbon deposits can get into the indicator.
Attention:
The screwed connection between the indicator and indicator valve must be gas-tight
during assembly!
A finger-tight, form and force-locking connection must be attained.
•
Indicating
Attention:
Completely close the indicator valve after the indication process.
Loosen the connection when there is no pressure at the indicator.
•
Note the following on the diagram: date, engine number, cylinder number, exhaust
temperature after the cylinder, fuel injection, engine speed, charging air pressure.
Attention:
The firing pressure is not allowed to be corrected by changing a correctly adjusted feed
start. This will reduce the cylinder power!
