Operational misfire
In general, „operational misfire“ means that the engine is operated with non-uniformly
loaded cylinders.
This will cause additional loads which are the higher the more the march of the gas pressu-
re of a defective cylinder deviates from the remaining cylinders.
Attention:
Therefore we strongly recommend not to carry out any adjustments at the engine which
might result in an output reduction of individual cylinders!
In any case, troubles detected at individual cylinders should be remedied immediately!
In case the operational misfire cannot be avoided, i.e. cannot be repaired by means of on-
board tools, we differentiate between the following extreme conditions, depending on the
severity of the troubles:
1.
Misfire
Misfire means engine operation with interrupted injection at any cylinder.
The compression pressure of the troubled cylinder, however, is applied.
At engine operation the following has to be observed:
•
Required output and speed restrictions are indicated in the torsional vibration
calculation (
•
Even if there are not restrictions regarding the position of the torsional vibration, it is
recommended to check a flexible coupling for excessive heating.
•
It has to be
avoided
that with permanently existing engine load variations a „surging“
of the turbocharger occurs in any operating point.
•
In case of an excessive vibration of the control rack you should relocate the operating
point in order to reduce the vibrations.
