DIX_Firing_Window_Start / DIX_Firing_Window_End
Tip Strip: Start of angle-based window around all injection events for a channel, End of angle-based window
around all injection events for a channel
Units: DBTDC
Detail: The three channels within a DI Driver module share driver circuitry and are multiplexed. Only one
channel within a DI Driver module is able to operate at one time. Therefore angle-based firing windows are
used to define a period during which an injection event can take place for a given DI Driver channel. A firing
window is created around each DI Driver channel, specified by a firing window start and end parameter for
each DI Driver module. The firing window must not be greater than a span of 240 degrees, such that the
firing windows around each of the three channels overlap. If the windows around each of the three DI Driver
channels overlap, then the
the three injector channels may not operate.
DIX_Firing_Window_Start: Defines the start of the window in Degrees Before Top Dead Center (DBTDC).
The TDC reference for the window is the
channel.
DIX_Firing_Window_End: Defines the end of the window in Degrees Before Top Dead Center (DBTDC).
The TDC reference for the window is the
channel.
Firing Window Overlap Detected
Tip Strip: Indicates that the firing window for one channel overlaps with the next multiplexed channel within
the module
Detail: This indicator will be set to TRUE if any
a single DI Driver or PFI Driver module.
