Type 2:
With most engines it is recommended to use only this
acceleration type 2. However type 2 can be combined
with type 1 (for some engines useful).
Acceleration enrichment type 2 is always linked to main
engine load.
The initial burst is one pulse that is directly injected
when needed no matter what crank position and will
intervene to avoid a short lean mixture. The sensitivity is linked to opening speed of the throttle. A low
value for sensitivity means that the initial burst won’t occur fast, a high throttle opening speed is
needed. For a high sensitivity value a lower throttle opening speed is needed for initial burst
enrichment to occur. The amplifier is more or less a factor for the amount of fuel injected. A higher
amplifier results in more enrichment.
Additional enrichment follows after the initial burst. After the initial burst, the mixture briefly can get
lean again. More enrichment is
needed. You can choose how
many rotations the additional
enrichment is needed. The amount
of extra fuel will slowly decrease
during these rotations. Sensitivity
and the amplifier function the same
as they do with the initial burst.
The additional enrichment can be
increased by a percentage for the
water temperature. More
enrichment is needed with a low
water temperature.
The figure on the right gives an
indication of how these two types
of enrichments affect the mixture,
when suddenly the throttle valve is
opened.
3.4.1.6
Interpol. to limits and Fuel cut
This function can disable the interpolation between
values of the fuel map when the outer limits of the map
are 0.0. This enables a safe engine speed limiter to be
set or to stop injection entirely when the accelerator is
released. In the case of the speed limiter, the engine
can be prevented from running on an increasingly poor
fuel air mix, which might cause engine damage. This
does not apply when the speed limiters are set to a
lower maximum engine speed. We recommend to use
the standard limiters (see also section:
