Adjustment of the valve of increase in frequency of rotation of idling

On the cars equipped with automatic transmission (release till December, 1984) or the conditioner, there is a pneumodrive 4 (see fig. Pnevmoprivod of a butterfly valve of the first chamber) with four unions for connection of vacuum hoses and the valve 6 of increase in frequency of rotation of idling. At inclusion of a large number of consumers of energy (headlights, a radio tape recorder, heating of glass of a window of a back etc.) and change of modes of movement or turning on of the conditioner as a result of big loading frequency of rotation of idling decreases. Thus works the valve 6, submitting additional amount of fuel that increases frequency of rotation of idling to the nominal. The valve of increase regulate, if frequency of rotation of idling under loading too low or if the engine stops.

Adjustment to make on the heated-up engine with the adjusted gaps in the mechanism of a drive of valves and correctly established the ignition moment at completely open air zaslonka in the following order:

Heater of an inlet pipe

1–inlet pipe;

2–laying;

3–sealing ring;

4–heater;

5–holder;

6–collar;

7–hose of heating of an inlet pipe

For improvement of evaporation of gasoline at start when the engine cold, from below an inlet pipe is established an electric heater. It heats up within several seconds and is disconnected, when the temperature of cooling liquid reaches 65 ° With after that the inlet pipe is warmed up by liquid from cooling system.

Check a heater on the cold engine as follows:

PERFORMANCE ORDER
1. To disconnect a wire of a heater 4 from a connecting block.
2. To a wire of a heater to connect an ohmmeter, the second wire of an ohmmeter to connect to "weight". To measure resistance of a heater, it should be 0,25–0,50 Ohm. If resistance differs from specified, to replace a heater.
3. At replacement of a heater to replace laying 2 and a sealing ring 3.

Check of a thermoswitch of a heater of an inlet pipe

The thermoswitch disconnects a heater of an inlet pipe when the temperature of cooling liquid will reach 65 ° S.Termovyklyuchatel the thermoswitch 16 (see fig. is established at engines in working volume of 1,1 and 1,3 l in a hose between an inlet pipe and the thermostat case, at engines in working volume of 1,6 and 1,8 l. To a detail of system of cooling of engines in working volume of 1,6 and 1,8 l) it is established in a branch pipe of the 18th shirt of cooling.

PERFORMANCE ORDER
1. To remove a stopper of a broad tank, to reduce pressure in cooling system.
2. To turn out a thermoswitch and to muffle an opening that cooling liquid did not follow.
3. To connect to thermoswitch conclusions an ohmmeter.
4. To lower a working part of a thermoswitch in the water which has been heated up to temperature of 65 ° With for engines by working volume of 1,1 l or 55 ° With for engines in volume 1,3; 1,6 and 1,8 l. To measure resistance of the switch, it should be equal to zero, i.e. contacts of a thermoswitch are closed.
5. To heat up water to temperature 75 ° With for engines in volume of 1,1 l and 65 ° With for engines in volume 1,3; 1,6 and 1,8 l. To measure resistance of the switch; it should equal infinity, i.e. contacts of the switch are opened. Otherwise to replace a thermoswitch.

Check of a thermoswitch of the automatic starting arrangement

The thermoswitch disconnects electroheating of the automatic starting arrangement when the temperature of cooling liquid reaches 42 ° S.Posle etogo the starting arrangement is warmed only with cooling liquid.

Procedure for test of a thermoswitch 27 (see fig. Details of system of cooling of engines in working volume of 1,6 and 1,8 l) same, as thermoswitch of a heater of an inlet pipe.

Resistance of a thermoswitch to 33 ° With – a zero, above 42 ° With – infinity.

Check of the automatic starting arrangement

PERFORMANCE ORDER
1. To remove the air filter.
2. Slowly once to press an accelerator pedal. The air zaslonka of the carburetor should be closed.
3. To start the engine. The air zaslonka should open approximately through 5 mines, depending on air temperature. If the air zaslonka is closed too sooner or later, it is possible to turn a cover 32 (see fig. Pierburg/Solex 2E2 carburetor details) the starting arrangement at most on 5 mm from a label on the case of the starting arrangement. If it does not help, to replace the starting arrangement.

Pneumovalve check with a thermal timer

PERFORMANCE ORDER
1. To disconnect from the valve 17 (see fig. To a Pierburg/Solex 2E2 carburetor detail) a vacuum hose and to turn out the valve.
2. To blow the valve. At temperature below +18 ° About the valve it should be open, at temperature above +28 ° With – it is closed. If it is necessary, it is possible to cool the valve in the refrigerator or to heat up on a water bath.

In a vacuum hose between the valve and a pneumodrive of a butterfly valve of the second chamber the throttle which has marks is established: the dark blue – for the engine in working volume of 1,6 l, yellow – for the engine in volume of 1,8 l.

The short hose dressed on the external union of the valve, should be open. This hose protects the valve from pollution.
