IGNITION AND INJECTION

IDLING REGIME ADJUSTMENT DUE TO BATTERY VOLTAGE
The idle mode of t he engine is influenced by the voltage of the battery with a view t o
compensating the voltage fa ll caused by the coupling of the consumers when the battery is
poorly charge d; this imposes an increase in the idle mode revolution ra tio, so the ratio of
the alternator will be incre ased by increasing the charging voltage. The lower the voltage,
the more significant the correction applied, which begins under 12.7 V.
The idle mode regime can thus be incre ased up to 830 rot/min.
If the injection calculator receives the information “command AC coupling”, then the
idle mode revolution ra tio will go up to 850 rot/min.
VA LUES « IDLING RCO « AND « IDLING RCO ADAPTATION «
P
RINCIPL E:
In order to use the information related to the parameters value “PR 021= RCO idling“
and “ PR 022= RCO idling”, the CLIP tester is to be used, which will be connected at the
diagnosis socket and at the vehicle battery ( or lighter socket). Select on tester m enu “COMPUTERS TEST”, then “PETROL INJECTION” . Find then
“FUNCTIONS TEST” and read here the progress of the PR 021 and PR 022 parameters.
In normal operation conditions, warm engine, the value RCO idling ( PR 022 ) is changing
between a maximal a nd a minimal value, so that nominal idling RPM is obtained. It is
possible that further to an operation dispersion ( runni ng in, engine choking up,etc) the
value “RCO idling” to get closer t o the minimal or m aximal value. The adaptive correction (PR 021 ) on “ RCO idling” (PR 022) is allowing r eaching at slow
variations of the engine air necessities, so that “RCO idling” is re-set on an average nominal
value. The parameters PR 021 and PR 022 are progressing among the following limits :

AT TENT ION
In case of acid slashes on body, abundantly wash with water al l affected parts.
If eyes have been touched, urgently call for a doctor.
1. DANGER = EXPLOSION RISK
During battery charging, connected to a charger-rectifier, oxygen and hydrogen emissions are
occurring. These gases emission is stronger when the battery has reached the complete charge
condition and the produced gas quantity is in direct connection with the charging current. The oxygen and hydrogen are associating in the free spaces, at the plates surface, forming a
detonate mixture, which is very explosive. The littlest spark is sufficient to generate an explosion,
followed by the battery case brooking and a cid splashing in the proximate environment. The
persons, who are a round, are in da nger t o be hurt by t he e xploded case chips or by the acid,
which may come i n contact with the eyes, hands, or face.
AT TENT ION
Strictly observe the following recommendations:
- before connecting or reconnecting a battery, ensure that all consumers are
shouted off; -during battery charging in a room, using a c harger-rectifier, turn it off be fore
connecting or reconnecting the battery to this one;
-do not place m etallic objects on the battery for not producing a short-circuit
between its plugs;
-never bring closer to a battery, an open flame, a welding lamp or another fire
source.
THE ELECTRIC EQUIPMENT PROTECTION
In case of an intervention on the vehicle, some measures must be taken, for the electric equip-
ment protection against damages or for avoiding a short-circuit that may lead to vehicle firing. The
battery is to be allwith disconnected by first disconnecting the negative plug and then the positive
one. Connection is to be done by performing the disconnecting operations in the reverse order.
Before starter acting, check if the battery is correctly connected (the negative plug connected
to the ground), and if the plugs are clean and well tightened. Never disconnect the battery when
the engine is running, in order not to damage the voltage regulator, the alternator or some
components of the vehicle checking electronic systems. The alternator, voltage re gulator
disconnecting, a nd the interventions at their connections, are to be performed only when the
engine is stopped (the alternator is not turning) and the contact is taken off. In case the battery is connected to a charger-rectifier, for charging (without dismounting the
battery off the vehicle), it is obligatory to disconnect the wiring from the battery plugs. BATTERY
