ESTTL2-X_Firing_Window_Start / ESTTL2-X_Firing_Window_End
Tip Strip: Start of angle-based window around all engine synchronous TTL-trigger-based events for a channel, End
of angle-based window around all injection events for a channel
Units: DBTDC
Detail: Even though the channels within the ESTTL2 module are independent and the output pulses can overlap,
the pulse sequence needs to be reset each engine cycle. The span of this window depends on the stroke of the
engine. For example, for 2-Stroke engines, the span is 360 Crank Angles, i.e. ±180 degrees around the reference
TDC. For 4-Stroke engines, the span is 720 Crank Angles (two crank rotations), i.e. ±360 degrees around the
reference TDC. The window may not overlap from cycle to cycle. For example, for 4-Stroke engines, the ESTTL2-
X_Firing_Window_Start and ESTTL2-X_Firing_Window_End cannot be exactly 360 and -360 DBTDC respectively. It
is recommended that the Start and End windows are offset by One Crank Angle degree from these absolute bounds
respectively.
ESTTL2-X_Firing_Window_Start:
Defines the start of the window in Degrees Before Top Dead Center (DBTDC).
The TDC reference for the window is the
value associated with the applicable ESTTL 2 module channel.
ESTTL2-X_Firing_Window_End:
Defines the end of the window in Degrees Before Top Dead Center (DBTDC).
The TDC reference for the window is the
value associated with the applicable ESTTL 2 module channel.
