[Pressure plot] shows the cylinder pressure at the respective indicator valve
depending on the crankshaft angle, at the top with activated first deriva-
tive.
A: Axis for the cylinder pressure, scaling in bar
This axis is automatically adjusted to the max. cylinder pressure of
the current measurement.
B: Crankshaft angle, scaling in °
This axis shows the position of the crank angle for the measured
Cylinder.
C: axis for the curve of the first derivative (dp / da)
D: 0 bar - line for the curve of the 1st derivative
E: TDC (top dead center) line
F: This cylinder pressure curve shows the pressure (rising / falling) de-
pending on the crank angle of the measured cylinders.
