Injection Timing Secondary

Injection Timing Secondary

Injector timing units are values in degrees.

Units are described as an “Advance Table”, so values are BTDC.

IE - 400 degrees = 400 degrees before TDC Cylinder 1 compression, or also 40 degrees before TDC between exhaust and intake stroke (overlap) - Valves Closed 

360 degrees = TDC between exhaust and intake stroke (overlap period)

300 degrees = 60 degrees after intake valve has opened 

SOI/EOI (Determines start of injection or end of injection) function is controlled under : Injection Timing Sec

Config -> Fuel -> Fuel Secondary Setup -> Injection Timing Sec

Allows the Timing of the Secondary Injectors to operate independently of the Primary Injectors.  The Sec Injectors can be advanced up during the initial transition into staged mode to help improve the overall smoothness during this event,
