6.8.33. Injection configuration — direct injection (pan_InjectorConfig_DI)

Configures constraints for direct injection.

6.8.33.1. Supported targets

M220-000, M221-000, M250-000 and M670-000

6.8.33.2. Required license

None (Main library). (See Section 2.3, “Licensed Features”.)

6.8.33.3. Description

The pan_InjectorConfig_DI block specifies constraints that are applied to the direct injection scheduling. See Section 6.5.2, “Direct injection” for an overview of direct injection and the mask parameters for this block for specific details.

6.8.33.4. Inports

None.

6.8.33.5. Outports

None.

6.8.33.6. Mask parameters

  • Minimum injection duration

    The minimum duration of any injection pulse. Set to zero if a minimum pulse duration is not required. If a requested pulse duration is greater than zero but smaller than this minimum time, the ECU will generate a pulse equal to this minimum time.

    The exception to the minimum injection duration is when the injection pulse is cut short due to the Drop dead angle.

    Range: [0, 2097] milliseconds

    Value type:Real
    Calibratable:Yes, offline
  • Minimum duration between injections

    The minimum time between pulses for a single injector, applied to all injectors. This parameter ensures a minimum time between pulses for an injector and will override the starting angle of a subsequent pulse if necessary.

    Range: [0.1, 1.0] milliseconds

    Note

    Contact Pi Innovo if application requires injector pulse separation outside of the range above.

    Value type:Real
    Calibratable:Yes, offline
  • Drop dead angle

    The drop dead angle applied to all cylinders, relative to the cylinder's TDC-firing angle (positive angles after TDC-firing). The ECU will stop injections at this point on a given cylinder. That is, it will terminate any pulse in progress (regardless of the Minimum injection duration and not schedule any subsequent pulses until the next cylinder cycle.

    Range: [0, 360) ° crank, for a two-stroke engine Range: [0, 720) ° crank, for a four-stroke engine Resolution: at least 0.1 degrees

    Value type:Real
    Calibratable:Yes, offline

6.8.33.7. Notes
