Fasi di funzionamento
Funzionamento normale
In condizione di motore termicamente regimato la
centralina calcola la fase, il tempo di iniezione, l’anticipo
di accensione, esclusivamente attraverso
l’interpolazione sulle rispettive mappe memorizzate, in
funzione del numero di giri e posizione farfalle; Inoltre la
sonda Lambda controlla il corretto funzionamento dei
catalizzatori.
La quantità di carburante così determinata viene eroga-
ta in due mandate in sequenza ai due cilindri.
La determinazione dell’istante di inizio erogazione, per
ogni cilindro, avviene per mezzo di una mappa in funzio-
ne del numero di giri.
Fase di avviamento
Nell’istante in cui si agisce sul commutatore di accensio-
ne, la centralina alimenta la pompa carburante per
alcuni istanti ed acquisisce angolo farfalla e temperatu-
ra relative al motore.
Procedendo alla messa in moto la centralina riceve
segnale di giri motore e fase che le permettono di
procedere a comandare iniezione e accensione.
Per facilitare l’avviamento, viene attuato un arricchi-
mento della dosatura di base in funzione della tempera-
tura dell’olio
Ad avviamento avvenuto ha inizio il controllo dell’antici-
po da parte della centralina.
Operation phases
Normal operation
When the engine is in standard thermic conditions, the
unit calculates the phase, the injection time, the ignition
advance, only by interpolation on the corresponding
stored presettings, according to rpm and throttle
position;Furthermore, the Lambda sensor checks for
catalytic converter proper operation.
The resulting amount of fuel is delivered to the two
cylinders with two subsequent injections.
The count of the initial delivery moment, for each cylin-
der, is made by means of a presetting that depends on
the number of revolutions.
Starting phase
When the ignition switch is in operation, the unit feeds
the fuel pump for few time and detects the throttle angle
and the temperature of the engine.
After starting the engine, the unit receives the revolution
and phase signals, which allow it to control the injection
and the ignition.
To make the starting phase easy, an enrichment of the
main quantity, upon the oil temperature, is performed.
After the starting phase, the unit begins the check of the
advance.
