After entering into the software the calibration data that you've in your carburetoror that you want testing, together with the
operating and the weather conditions, clicking the
START buttonsoftware SET-UP Carburetor calculates the carburetion
that your carburetor determines.
This carburetion is compared with that which the
carburetor should provide to allow the engine to have the
maximum performance.
In fact, in a 2-stroke engine with carburetor admissionthe
air / fuel ratio which allows to obtain the best performance
varies depending on the operating conditions (throttle opening
butterfly, engine speed) in that it must take into account, for example,
of the incomplete vaporization of the mixture which there is a low
load, or of the additional demand of fuel that is necessary at high
speed, etc.
The comparison is done both at partial loads (in the different
throttle openings), both at full load (in all speed
of operation), thus it will be possible to optimize the
jetting in all operating conditions and therefore have
maximum performance at all points of the track and in all
the driving conditions.
The green line is the optimum carburetion for the engine, while the red line is the carburetion that carburetor gives with the
calibration that you've entered, so already just looking at the graphs
understands immediately what are the points to be improved in order to obtain
the carburetion better for the engine.
In the figure shown for example of the carburetion at the partial loads
you see that you have a good carburetion in first opening,
then the carburetion is a bit richer than it should be,
until it becomes lean in thetransition.
While in the figure relative to the carburetion at full load you can see that with the calibration inserted the carburation is lean in all
the operation range.
In addition to the green and red lines the software also shows lines
which indicate the limits of lean carburetion (light blue) and
of rich carburetion (orange), beyond which it is not advisable
in any case go to avoid reliability problems or
malfunction.
In addition to graphics software SET-UP Carburetor immediately recommended interventions
to be made to correct the jetting and close as
possible to the optimum carburetion
In fact, for every operating condition the software SET-UP
Carburetor will indicate the situation (rich mixture, lean, or ok),
the percentage of the deviation from the optimum value, and especially how to act to improve the situation in the different zones,
indicating for first the calibration element most influential in that
area and to follow the others that affect.
