Adjusting the throttle priotkryvaniya second
Camera
Throttle position is adjusted at the factory and during operation adjustment is required. If the adjustment has been broken, it can be restored in the same way as in the carburetor 2E3 (see. Subsection 3.1.12.4).
Check the air damper actuator
Checks are made in the same way as in the carburetor 2E3 (see. Subsection 3.1.12.4).
Check the heating element
Checks are made in the same way as in the carburetor 31R1S-7 (see. Subsection 3.1.12.2).
Adjusting the accelerator pump
| PERFORMANCE ORDER | | 1. Remove the carburetor. | | 2. Disconnect the vacuum hoses from the actuator 13 (see. Fig. Details carburettor Pierburg / Solex 2E2) throttle the first chamber. | | 3. Connect to the union and the vacuum pump. The close fitting plug (if the actuator with four nipples, stifle and choke C). | | 4. Create a vacuum in the actuator to the rod 3 (see. Fig. Adjustment priotkryvaniya throttle first chamber) moved away from the adjusting screw 1. |  | 5.

Remove the cover of the carburetor float chamber to fill with fuel and set the carburettor cover. | | 7. Put a carburetor measuring beaker with a funnel. | | 8. Turn the throttle to the first chamber from stop to stop 10 times, resulting in this action the accelerating pump, spending every turn about 3 seconds. | | 9. Measure the amount of fuel in a beaker and divide by 10; get the amount of fuel which is pumped in one cycle. This value should be for engines in working volume of 1,6 l 1,0 ?� 0,15 cm 3 engine capacity of 1.8 liters 1,1 ?� 0,15 cm 3. | | 10. If necessary, adjust the performance of the accelerator pump rotating cam 6 (see. Fig. Adjustment priotkryvaniya throttle first chamber), previously releasing the locking screw 7. |
|
Adjusting the idle speed
Regulation to make a warm engine to adjust the clearance in the mechanism of the valve is installed and ignition timing at full choke in the following order:
| PERFORMANCE ORDER | | 1. Turn off all power consumers (lights, fan, radio and so on. D.). | | 2. Disconnect the hose from the air filter crankcase ventilation and drown him. | | 3. Connect the control tachometer and analyzer. | | 4. Check that the rod 3 (see. Fig. Adjustment priotkryvaniya throttle first chamber) is in the idle position, and the screw shaft 3 concerned 1. | | 5. Turn the valve 5 (see. Fig. Pneumatic throttle first chamber) to adjust the idle speed within 950 ?� 50 min -1. | | 6. The adjustment screw 24 (see. Fig. Details carburettor Pierburg / Solex 2E2) the quality (composition) of the mixture to set levels of carbon monoxide (CO) in the exhaust 1,0 ?� 0,5%. Check and, if necessary, to restore the idle speed. Check and, if necessary, to restore the CO content in the exhaust gases. |
|
Adjust the valve to increase idle speed
On vehicles equipped with automatic transmission (release till December, 1984) or the air conditioner, the actuator 4 (see. Fig. Pneumatic throttle first chamber) with four connections for connecting the vacuum hose and valve 6 to increase idle speed. When the large number of energy consumers (headlights, radio, heating tailgate window glass and so on. D.) And changing modes of movement or turn on the air conditioner as a result of a large load is reduced idling speed. When this valve 6 is activated, giving an additional amount of fuel, which increases the idle speed to the nominal value. The valve is controlled increase if the idle speed under load is too low or if the engine stops. Regulation to make a warm engine to adjust the clearance in the mechanism of the valve is installed and the moment of ignition at full choke in the following order:
| PERFORMANCE ORDER | | 1. Connect the tachometer and the control analyzer. | | 2. Tighten the hand brake, under the front wheels to set stops (such as wooden wedges). | | 3. Start the engine. Turn the heater fan on high, the high beam headlights, heated glass tailgate window. | | 4. Sitting in the car all the way up to the assistant should press on the brake pedal and move the selector lever to the transmission control switch ?�D?�. | | 5. Check whether abuts stop screw 1 (see. Fig. Adjustment priotkryvaniya throttle first chamber) in the control rod 3. tachometer to check engine speed. If it is below 800 min -1 (see. Fig. Pneumatic throttle first chamber) rotating valve 6 to adjust it. | | 6. Disconnect vacuum hose 2 from the tee 1 and drown him. Start the engine and check the speed of the start-up. If it is below 3000 ?� 200 min -1, adjust the screw 1 (see. Fig. Adjustment priotkryvaniya throttle first chamber). After the adjustment screw Lock the paint. | | 7. Connect the vacuum hose 2 (see. Fig. Pneumatic throttle first chamber) to a tee 1. Check idle speed. |

Check the heater inlet pipe Heater inlet pipe | 1 - inlet pipe;
2 - a lining;
3 - O-ring;
4 - heater;
5 - the holder;
6 - a collar;
7 - heater hose inlet pipe |
To improve the evaporation of gasoline at the start when the engine is cold, the bottom inlet pipe installed electric heater. It is heated for a few seconds and is turned off when the coolant temperature reaches 65 ?� C, then heated liquid inlet pipe of the cooling system. Check the heater on a cold engine as follows:
| PERFORMANCE ORDER | | 1. Disconnect the heater 4 from the connecting pads. | | 2. To connect the heater wire ohmmeter ohmmeter second wire connected to "weight". Measure the resistance of the heater, it must be 0.25-0.50 ohms. If resistance differs from specified, replace the heater. | | 3. When replacing the heater to replace the gasket 2 and the O-ring 3. |
|
Checking the thermal switch Heater inlet pipe
Switch turns off the heater inlet pipe, when the coolant temperature reaches 65 ?� C temperature switch installed at the engine working volume of 1,1 and 1,3 l in the hose between the inlet pipe and thermostat housing, at engines in working volume of 1,6 and 1,8 l thermal switch 16 (see. Fig. Parts of the cooling system of engines in working volume 1,6 and 1,8 liters) installed in the pipe 18 of the cooling jacket.
| PERFORMANCE ORDER | | 1. Remove the surge tank cap to reduce the pressure in the cooling system. | | 2. Remove the temperature switch and seal the hole to avoid leaking coolant. | | 3. Connect the thermal switch to the terminals ohmmeter. | | 4. Lower the temperature switch part to water heated to 65 ?� C for engines working volume of 1.1 liters or 55 ?� C for engines volume of 1.3; 1,6 and 1,8. Measure the resistance switch, it must be equal to zero; thermal switch contacts are closed. | | 5. Heat the water to 75 ?� C for engines volume of 1.1 liters and 65 ?� C for an engine capacity of 1.3; 1,6 and 1,8. Measure the resistance of the switch; it must be infinite, ie. e. switch contacts open. Otherwise, replace the thermal switch. |
|
Checking the thermal switch automatically trigger device
Switch disables automatic start-up electric heating device when the coolant temperature reaches 42 ?� C. After that, the starter only heated coolant.
To verify temperature switch 27 (see. Fig. Parts of the cooling system of engines in working volume of 1,6 and 1,8) is the same as the thermal switch heater inlet pipe. Resistance temperature switch to 33 ?� C - zero above 42 ?� C - infinity.
Check the automatic starting arrangement
| PERFORMANCE ORDER | | 1. Remove the air filter. | | 2. Slowly click once on the accelerator pedal. Choke the carburetor should be closed. | | 3. Start the engine. Air damper should be opened after about 5 minutes, depending on ambient temperature. If the air damper is closed too early or too late, you can rotate the cover 32 (see. Fig. Details carburettor Pierburg / Solex 2E2) starting device for a maximum of 5 mm from the label on the housing of the starting device. If this does not work, replace the starter. |
|
Checking the air valve with a thermal time relay
| PERFORMANCE ORDER | | 1. Disconnect from the valve 17 (see. Fig. Details carburettor Pierburg / Solex 2E2) vacuum hose and remove the valve. | | 2. Purge valve. At temperatures below 18 ?� C, the valve must be opened, at a temperature above 28 ?� C - closed. If necessary, the valve can be cooled in a refrigerator or heated in a water bath. |
|
In the vacuum hose between the valve and pneumatic throttle set the throttle of the second chamber, which is the mark: Blue - Engine 1.6-liter, yellow - for the engine capacity of 1.8 liters.
Short hose, wearing an external choke valve to be opened. This hose protects the valve against contamination.
