The 2EE carburetor represents the carburetor 2Е2 with electronic control. The drive of an air zaslonka and a drive of a butterfly valve of the first chamber cope the electronic control unit with the microprocessor. The control unit is established in car salon about a ware box on the dashboard. The lambda probe, established in the additional exhaust silencer, measures the content of oxygen in the fulfilled gases and gives a signal in the control unit. The control unit on the basis of a signal from a lambda probe changes composition of gas mixture so that fulfilled gases optimum дожигались in converter.

The following operations carry out the same as on the carburetor 2Е2:

 – removal and carburetor installation;
 – adjustment of a priotkryvaniye of a butterfly valve of the second chamber (see subsection 3.1.12.5);
 – check of a heater of an inlet pipe (see subsection 3.1.12.5);
 – check of a thermoswitch of a heater of an inlet pipe (see subsection 3.1.12.5).

Check of frequency of rotation of idling

In the 2EE carburetor there is no screw of adjustment of quantity of a mix.

PERFORMANCE ORDER
1. To warm up the engine, the temperature of oil should be not less than +60 ° Page.
2. To muffle the engine, to switch off everything consumers of energy (headlights, the fan, a radio tape recorder etc.).
3. To disconnect a hose of ventilation of a case.
4. To connect a control tachometer.
5. To start the engine and to leave to idle.
6. To check frequency of rotation of idling, it should equal 750 mines-1. If frequency of rotation of idling differs from specified, to define malfunction by system of diagnostics and to eliminate it.

Check and adjustment of the maintenance of an oxide of carbon in the fulfilled gases

The maintenance of an oxide of carbon (WITH) in the fulfilled gases check the special indicator of tension with VAG 1527 light-emitting diode. By character of light impulses of a light-emitting diode determine the contents WITH in the fulfilled gases. It is forbidden to use usual control lamps since electronic systems can be damaged.

Check carry out on the heated-up engine at oil 60 temperature ° With in the following order:

PERFORMANCE ORDER
1. To connect a gas analyzer to a special branch pipe for measurement WITH on the additional exhaust silencer of the first step.
2. To disconnect a hose of ventilation of a case.
3. To connect the indicator of tension of VAG 1527 to the control socket 1 on a blue wire.
4. To start the engine and for 1 mines to finish frequency of rotation above 2000 mines-1 that a lambda probe got warm to working temperature.
5. The light-emitting diode on the indicator of tension 2 at frequency of rotation of idling should blink with frequency 1,5 times a second (2 times for 3 c). If the light-emitting diode burns constantly, the mix too rich if the light-emitting diode does not burn means, the mix poor means. If the light-emitting diode blinks with frequency of 25 times a second, the lambda probe means or did not get warm to working temperature either is faulty, or the wire to a lambda probe is damaged.

Prevention

The lambda probe can be hammered by a soot that can cause probe misoperation. To clear a probe, it is necessary to make a smooth trip on the highway during 20 mines after that to repeat check.


6. To check level WITH by means of a gas analyzer. It should make 0,6 %. If, despite the correct indications of a light-emitting diode of the indicator of tension, level WITH differs from specified, it needs to be adjusted. For this purpose to disconnect a wire from a lambda probe, a nest a lambda probe заизолировать an insulating tape. The light-emitting diode of the indicator of tension thus should blink. To take out a plastic cap of the screw 6 (see fig. 2EE carburetor details) for what to drill in a cap an opening to screw in it a screw and for it to pull out a cap. Rotating the screw 6, to adjust the contents WITH in the fulfilled gases.
7. To insert a new cap, to disconnect a gas analyzer and the tension indicator. To connect a wire to a lambda probe. To connect a hose of ventilation of a case.

The simplified check of work of Ecotronic system

At failure a lambda probe the Ecotronic system works according to the emergency program. For check of work on the emergency program it is necessary to disconnect a lambda probe and to track opening and closing of an air zaslonka. If the zaslonka functions, means works an emergency control.

PERFORMANCE ORDER
1. To warm up the engine, the temperature of oil should be not lower 60 ° than Page.
2. To remove the air filter.
3. To disconnect from the carburetor a vacuum hose 24 (see fig. Air filter of engines in working volume of 1,1 and 1,3 l). To muffle a branch pipe on the carburetor.
4. To start the engine and to leave to idle.
5. To disconnect a wire a lambda probe 1 from a connecting block 2. Thus the air zaslonka should open on a corner about 60 °. If it does not occur, the emergency control means does not work or the drive of an air zaslonka, or a wire a lambda probe does not work closes on "weight".
6. If the air zaslonka opened correctly, to connect a green wire with a block 2 to "weight" approximately on 2 villages. The air zaslonka should be slightly opened slowly a little. If it did not occur, to check, whether conducting and if is not present is damaged, to replace the control unit with the microprocessor.
7. To increase frequency of rotation of the engine to 2000 mines-1 approximately on 1 mines that a lambda probe got warm to working temperature.
8. To connect a wire 1 lambda probe to a block 2.
9. At operation of the engine idling to remove a cap from a carburetor branch pipe. The air zaslonka should be covered slowly a little. If it does not occur, the lambda probe means is faulty and it is necessary to replace it. If a lambda probe it is hammered by a soot, it is necessary to make a trip on the highway during 20 mines and after that to repeat check.
10. To muffle the engine. To connect a hose 24 (see fig. The air filter of engines in working volume of 1,1 and 1,3 l) to a branch pipe of the carburetor and to establish the air filter.

Check of elements of Ecotronic system

The schedule of dependence of resistance of the sensor of cooling liquid from temperature


Check of the sensor of temperature of cooling liquid

The sensor of temperature of cooling liquid is established in an inlet pipe of the engine or in a branch pipe of a shirt of cooling. The signal of the sensor arrives in the control unit. At failure of the sensor engine start-up worsens at low temperature of air.

PERFORMANCE ORDER
