Kindly note that logging events regularly (every month) during normal operation of the Engine and during issues is consider as good practice. The same can be very helpful for the troubleshooter as well as for comparison purposes.

One of the most obvious ways to find a problem is if you know how to decipher the parameters and graphical interpretation of the marked groups of graphs. in real practice, I always try to record graphs when the engine is in good condition at various loads…then this helps a lot in finding an error or malfunction.

Dear Collogues, If anyone has examples of graphs (I’m attaching them as an example), you can post them in the chat for discussion, of course, if you don’t mind. Brgds

…this signal jump is present in all operating modes and does not affect the operation of the diesel engine, gas temperatures are normal…(MAN ME 6S60 С )

This overshoot in the exhaust valve graph is perfectly normal.
It shows that the exhaust valve is opening normally and the dumping force is present (meaning that the valve returns in a higher position as a result of dumping force found usually on the high force exhaust valves)
