Smooth-Running Values




Smooth-Running Values
- Temperature at the radiator outlet at start of measurement: (#tka_beginn1#) °C
- Engine temperature at start of measurement: (#tmot_beginn1#) °C
- Desired speed during measurement: (#solldrehzahl#) ± (#toleranz#) rpm
- Actual speed during measurement: (#durchschnitt_drehzahl#) rpm






- Standard deviation:
If the standard deviation is greater than 0.15, the measurement is invalid.

- Mean value:
The smooth-running values indicate whether a cylinder accelerates or decelerates the crankshaft during its operating cycle. A negative value indicates an accelerating cylinder, while a positive value indicates a decelerating cylinder.
