In the case of fixed stroke speeds without dynamic cams, the TDC switch-off
occurs on the leading edge of the over run cam.
For the TDC stop at variable stroke speeds, a separate electronic cam switchgear
is provided that calculates the brake engagement point from the stroke speed. This
dynamic cam switches in the range of 320° to 340°, for example, and takes over
the TDC switch-off on a falling edge.
