Хайде де колеги, не се срамувайте, ударете по едно рамо! 
Ако предположим че моят двигател е AFC (каквото и да значи това) според долните писаници си е сериино без 5-та дюза, а Байпаса се вкл. от ключето за затворен дросел!
Е да ама аз го проверих това и си РАБОТИ
Според долният текст излиза и че има отделна джаджа която командва свободните обороти, а не ЕКУ-то?
И се намира пред
задният десен стоп ?????И с нея стават три отделни модула: ЕКУ, модул за впръскването на горивото, и модул за свободният ход?
Е, да ама аз намирам само два модула? Къде е третият?

DescriptionThe Bosch AFC Digifant system is a computer-controlled fuel injection system. The
system does not use cold start injector or thermo time switch for cold start enrichment.
Different sensors and switches, along with Electronic Control Unit (ECU), regulate fuel
injection and ignition timing.
Typical Digifant System ControlsElectronic Control UnitThe ECU controls all engine operations, and limits maximum engine speed. It receives
information from various input devices.
Input Devices* Air Flow Sensor (Air Flow Meter)
All intake air is drawn through the airflow sensor. The airflow
sensor contains a tunnel with a measuring flap and dampening
flap. The measuring flap swings with intake air stream against
pressure of a spiral spring and is connected to a potentiometer.
The potentiometer transmits an electrical signal determined by
measuring flap position to inform ECU of engine load. At idle, the
measuring flap is almost closed due to spring pressure.
The potentiometer within the airflow sensor prevents loss of
engine power during engine load or sudden acceleration (along
with engine speed and coolant temperature) by signaling the ECU
of necessary enrichment and timing requirements.
The airflow sensor contains an intake air temperature sensor. An
adjustable idle air by-pass screw influences CO levels at low
engine speeds. A tamper-proof plug is installed over this screw.
* Coolant Temperature Sensor (Digifant I)
The coolant temperature sensor is a temperature sensitive variable
resistor sensor (less resistance as temperature increases). This
sensor returns signals to the ECU to determine amount of cold
start enrichment, ignition timing and idle stabilization during
warmup. The sensor return signal has input to the ECU when the
oxygen sensor, idle stabilization, and full throttle enrichment
functions are activated.
* Coolant Temperature Sensor (Digifant II)
The coolant temperature sensor is a temperature sensitive variable
resistor sensor (less resistance as temperature increases). This
sensor returns signals to the ECU to determine amount of cold
start enrichment, enrichment during warm-up and ignition timing
control.
*
Full Throttle Switch (Digifant II)The full throttle switch closes approximately 10 degrees before
Wide Open Throttle (WOT). The ECU uses this signal for full
throttle enrichment.
* Hall Effect Sensor
See ELECTRONIC IGNITION SYSTEM under IGNITION
SYSTEM in this article.
*
Idle Switch (Digifant II)Idle switch closes when throttle is closed. The ECU uses idle
switch input for idle stabilizer valve, deceleration fuel shut-off and
activation of ignition timing map for deceleration. Idle switch
opens when throttle is opened approximately one degree.
* Intake Air Temperature Sensor
Intake air temperature sensor is a thermistor-type variable resistor
(resistance decreases with increase of temperature). This sensor
voltage signal varies to ECU in relation to engine air temperature.
Sensor is located inside the airflow meter.
* Knock Sensor
Vibrations in engine block will cause the quartz crystal inside
knock sensor to produce a small voltage. The ECU monitors this
small voltage. Ignition timing is retarded 3 degrees initially when
detonation begins to occur. Timing is retarded only in the cylinder
which is detonating.
When detonation stops, ignition timing is advanced in .33 degree
increments until a preprogrammed value is reached. If detonation
continues or reoccurs in a cylinder, ignition timing can be retarded
up to 15 degrees for each cylinder. The difference between any 2
cylinders is limited to 9 degrees.
* Oxygen (O2) Sensor
The O2 sensor detects oxygen content in the exhaust gas and sends
this information to the ECU. In operation, the ECU receives
signals from the O2 sensor and varies the duration during which
fuel is injected. A high voltage signal indicates
The O2 sensor is heated electrically for rapid warm-up and
constant operating temperature. Power to the heating element is
supplied whenever ignition switch is turned to ON position.
* Power Steering (P/S) Pressure Switch
The P/S oil pressure switch signals the ECU when the power
steering load is high. The ECU then sends a voltage signal to the
idle stabilization valve to increase idle speed with power steering
load.
* Throttle Potentiometer (Digifant I)
Throttle potentiometer is used by ECU to sense throttle position.
This signal is also used for activation of idle stabilization system
and deceleration fuel shut-off.
* Throttle Valve Switch
Throttle valve switch supplies ECU with information that throttle
valve is closed. If engine is above 1250 RPM with throttle closed,
fuel will be shut off to the injectors. At idle speed, this switch
signals control unit to regulate amount of fuel injected.
Output Signals• Idle Air Stabilizer Valve - See IDLE SPEED.
• Fuel Injectors - See FUEL CONTROL.
• Ignition Coil Control - See IGNITION SYSTEM.
Fuel Delivery* Electric Fuel Pump
The fuel pump provides fuel under pressure to the fuel pressure
regulator. Power for operation during cranking mode is provided
from starter relay via the fuel pump relay. After the engine has
started, control of the fuel pump is through the ignition signal. The
fuel pump is sealed unit.
* Fuel Pump Relay
When energized by the ignition switch and grounded by the ECU.
The fuel pump relay provides battery voltage to the fuel pumps,
injectors, idle stabilization control unit, oxygen sensor heating
element and the power steering pressure switch.
* Fuel Pressure Regulator
The fuel pressure regulator is a sealed, spring loaded diaphragm
with connection for intake manifold vacuum. Fuel pressure is
maintained at about 36 psi (2.5 kg/cmý) pressure.
A connection for intake manifold vacuum provides a constant
pressure differential which ensures that the amount of fuel injected
is solely dependent upon injector open ON time. Excess fuel is
returned to fuel tank. No service of pressure regulator is required.
The pressure regulator is located on or near fuel rail.
*Fuel Control
Data on engine temperature, engine speed, intake air volume, throttle position,
exhaust oxygen content and intake air temperature are used by ECM to
determine injection pulse width.
*Fuel Injectors
A fuel rail links the fuel pressure regulator with the fuel injectors.
Each cylinder is provided with a solenoid-operated injector which
sprays fuel toward backside of each inlet valve. Each injector is
energized through the ignition coil and grounded through the ECU
to complete the circuit.
Each injector is linked to a resistor (resistor may be external or
integral with injector or ECU) to reduce operating voltage to 3
volts and to protect injectors from power surges. The ECU
controls length of time each injector is open. The ON time of the
injector governs the amount of fuel delivered. The injector
delivers 1/2 the amount of fuel required for an operating cycle
each time they open (twice per cycle).
Idle Speed* Idle Stabilization Control UnitThe idle stabilization control unit is located in front of the right-hand taillight
assembly.
If engine idle speed differs from the value stored in the idle
stabilization control unit, the idle air stabilizer valve adjusts the volume of air
entering the engine at idle. The idle stabilization control unit receives
information from the following:
• Coolant Temperature Sensor
• ECU Control Relay
• ECU
• Oxygen Sensor
• Power Steering Oil Pressure Switch
Ignition System* Electronic Ignition System
The Hall Effect sending unit in the distributor uses a shutter
window wheel, mounted on the distributor shaft. The shutter
blades pass in and out of the air gap of the hall effect sender,
resulting in signal pulses. There is one shutter window for each
engine cylinder.
Signals from distributor hall sender are sent to the ECU. The ECU
sends a switching voltage signal to the ignition coil primary circuit
to discharge secondary spark voltage.
* Ignition Timing Control System
Signals from distributor hall sender are sent to the ECU, which
produces a pulsating signal to the ignition coil. This computed
signal from ECU to ignition coil controls ignition timing
according to engine load (airflow sensor signal), engine speed
(Hall Effect signal) and engine coolant temperature.
Emissions System* Evaporative Emissions System
Fuel vapors are collected in the expansion tank. Liquid gasoline
collects in expansion tank and flows back to the fuel tank through
vent lines. See Fig. 4. When engine is not running, fuel vapors are
drawn from tops of the expansion tanks, and flow into carbon
canister, where vapors are stored.
After engine is started, the control valve is opened by throttle
vacuum. Fresh air is drawn into bottom of the canister. Fuel
vapors from the canister are drawn into the intake manifold.
* Thermostatic Air Cleaner
During cold engine operation a regulator flap located inside air
cleaner assembly is opened so engine can draw warmed air from
around exhaust system. Vacuum from throttle valve operates
regulator flap. The regulator flap is controlled by a temperature
regulator valve located in upper part of air cleaner assembly.
When engine becomes warm, temperature regulator valve should
close causing regulator flap to close, stopping warm airflow from
around exhaust.
Self-Diagnostic System* O2 Sensor Warning Light
All vehicles are equipped with an O2 sensor warning light, located
on the instrument panel. The light illuminates when a mileage
counter reaches 60,000 miles (90,000 miles on Vanagon)
indicating recommended O2 sensor replacement and mileage
counter reset.
* Check Engine Light
California vehicles are equipped with a CHECK engine light and
rocker switch on the instrument panel. The light illuminates when
the ignition switch is turned to the ON position (for bulb check)
and when engine management systems malfunction during normal
engine operation.
