EngineStatus
Tip Strip: Engine status based on StallSpeed and CrankRunThreshold
Detail: Indicates the status of the engine crankshaft as stalled, cranking, or running, depending on the values
of
STALLED:
CRANKING:
RUNNING:
Crank speed is greater than
MaxCAT
Tip Strip: Maximum crank angle ticks for complete engine cycle
Units: CAT
Detail: Maximum Crank Angle Ticks per engine cycle. A Crank Angle Tick (CAT) is a single unit of angular
is reported as power-of-two angular ticks of crank position travel,
having a resolution dependent on binary extrapolation level and the number of physical teeth per crankshaft
rotation. For example, if using the
, which has an extrapolation of 7, the number of CAT per
crank tooth would be 2^7=128, and the internally calculated CurrentPosition would be evenly incremented
by 128 CAT from one physical tooth to the next. If a 60-2 pattern were used and the engine was a 2-stroke,
the
per engine cycle would be 60*128=7680. If the engine was a 4-stroke, the
per engine
cycle would be 2*60*128=15360.
CrankCount
Tip Strip: EPT crank pulse count while in sync
Units: pulses
Detail: The latest tooth count referenced to crank tooth 0. Tooth 0 is determined according to the pattern that
is being tracked and is discussed within the
pattern specific EPT documentation
.
is provided in terms of a complete engine cycle and is reported as if there
were no missing or extra teeth in the pattern. For example, if
and
will range from 0 to 119.
