RPM meter

Page 4 of 24

Injection time threshold up to

the rpm meter determine

the engine phase

Number of injection per

cycle.

Rpm meter:

The current engine RPM calculation it is elaborated regarding aquired

parameters checking the signal on the elaborated channel

Prescaler:

(Injection number per cycle of combustion on one petrol injection)

This parameter is used by the system to get the correct RPM value.

The value must be set relatively of injection strategy adopted by petrol

injection system ECU.

Example:

Prescaler = 1

Minimun threshold = 1,2 ms

Injectionj 1 Extrapulse

The injection time is lower than

minimun threshold

therefore that’s not considered.

Injection 2

1 = SEFI (sequential) : The injectiors are active singularly,

one cylinder therefore it’s fed in just one time

per combustion cycle.

2 = Batch fired 2 Banks : The injectors are divide in two bank

one cylinder therefore it’s fed two time per combustion cycle.

4 = Batch fired 1 Bank (4 cylinders) : The injectors are drived

simultaneously therefore one cylinder in a 4 cylinders engine it’s

fed 4 times.

6 = Batch fired 1 Bank (6 cylinders) : The injectors are drived

simultaneously therefore one cylnder in one 6 cylnders engine it’s

fed 6 time.

CommutAtor

Switcher:

The switcher operation is characterized by logical functions customizable wich:

- Iterative control of switching processes.

- Assisted switching to gas on regarding the pressure reducer thermal status.

- Assisted switching to gas on regarding the engine load.

- Automatic switching to petrol if a lead pneumatic or a thermal reducer anomaly has been found

- Gas pressure management while assisted commutation phase.

required to enable the

gas switching.

Phase 1; Wait

: The system will wait a time

corresponding to setted seconds value during

the engine will be feeded to petrol.

Phase 2 ; Temperature test

: It comes verified

temperature of the reducer and if this is

insufficient attends the heating. When the

temperature is sufficient comes executed a gas rail

load until attainment the ideal pressure in order then

attends an equal time to the set up value in second

before proceeding to successive phase.

Phase 3 ; Drainage rail

: It comes unloaded

the present rail gas until attainment the

ideal gas pressure in order then switch to gas

if that is completed in an lower time

to that set time, otherwise passes to the

successive phase.

Phase 4 ; Switching wait

: The system attends an

set up value in second equal time during

which the engine is fed to petrol to

allow the alignment of petrol feeding system

integrators.

- Automatic switching

- Automatic switching

Phase 2 = 1 second

Phase 3 = 5 seconds

Phase 4 = 2 seconds

Warning: During the autocalibration procedure the auto switching function

is auto disabled to avoid unexpected auto switching, so if you want to enable

this function must you enable her by checking appropriate flag present in the

switching setup window.
