Question on smooth running of cylinders
2 Attachment(s)
How is smooth running used in diagnostics? What are the two screens telling me?
These may not be off of a Mercedes Benz but I'm still curious. tia |
It is used in misfire diagnostics. The numerical values allow you to pinpoint a mean deviation from the average speed of the crankshaft. The values -3.5 to 3.5 would be the expected range and values outside that indicate a misfire.
The graph is showing the acceleration and deceleration of the crankshaft. |
