DIX_HVTarget

Tip Strip: DI Driver high voltage setpoint for internal boost supply

Units: V

Detail: The working voltage set point of the internal boost power supply.

DIX_BackBoostTime

Tip Strip: Time period during which injector solenoid energy is directed back to the module boost power supply (after

end of pulse)

Units: msec

Detail: The time period at the end of the injection pulse for which the back-electromotive force (EMF) of the injector

solenoid is directed to the internal boost power supply.

IPhaseArray

When operating solenoid injectors, the

IPhaseArray

defines up to eight sequential current-drive phases within each

injection command. Each phase is implemented sequentially and can specify

and

current dithering

, and

drive circuit – high voltage or battery voltage

. The high voltage drive circuit should

only be used as little as necessary so that the internal boost power supply energy is conserved and not overloaded.

Please refer to the

DI Driver Rev F

manual for various

IPhaseArray

configurations and the resulting current profile of

the Solenoid injector. The

IPhaseArray

consists of the following parameters:

IPhaseDrive

Tip Strip: Selects low voltage or high voltage for the associated phase

Detail: When operating solenoid injectors, selecting these buttons will toggle the voltage drive source of the

associated phase between

high voltage (HV)

and

battery voltage (LV)

IPhaseArray

is used differently in piezo mode by enabling

DIX_PiezoEnable

. The eight elements of the

IPhaseArray

are divided into two groups. The first four elements are used for charging the piezo load at the beginning of injection,

and the last four elements are used for discharging the piezo load at the end of injection. The ability to select HV or

LV for each phase is not available for piezo injector operation because the high voltage driver circuit is always used

(as shown below).
