6.7. An atomizer of start-up of the cold engine and a thermotimer
THE GENERAL DATA

Atomizer of start-up of the cold engine () and a thermotimer ()

Atomizer of start-up of the cold engine (system Motronic)

Check

PERFORMANCE ORDER
1. Check is carried out at engine temperature not above 30 by S.Otsoedinite from an atomizer a socket and take aside.
2. Turn away 2 screws and get an atomizer, without disconnecting a gasoline pipe line. Exclude ignition operation, having disconnected and having earthed a high-voltage wire of the coil. Start the fuel pump on 1 mines, перемкнув its conclusions to the relay. In this time leaks of fuel from an atomizer it should not to be observed. Otherwise an atomizer replace. Switch off ignition and clean a crosspiece.
System L-Jetronic
3. Attach a socket to an atomizer and substitute under it a vessel. Ask the assistant to include ignition and a starter. The stream of the conic form should be observed. If a stream faltering clean an atomizer or replace.
4. If the stream is absent, check up pressure on a socket at starter inclusion. If pressure is not present, replace the thermorelay.

Thermotimer (the relay of a starting atomizer)

The thermotimer operates an atomizer of start-up of the cold engine, providing opening of a starting atomizer for a certain time which depends on engine temperature. The relay is mounted near to the gauge of temperature of a liquid. Check is carried out at engine temperature not above 30 With.

PERFORMANCE ORDER
1. Exclude ignition operation, having disconnected and having earthed a high-voltage wire of the coil. Remove from the relay a cover and connect the voltmeter to a black-yellow wire of a socket.
2. For this purpose ask the assistant to include ignition and a starter. Pressure should appear at the moment of inclusion of a starter and later 6–10 сек, depending on engine temperature, to disappear.
3. If pressure is, open a socket check up short circuit of contacts of the relay.
4. Attach a wire of the coil and warm up the engine to temperature not more low 41 S.Kontakty of the relay should be opened. Otherwise the relay replace.

Replacement

PERFORMANCE ORDER
Starting atomizer
1. Execute декомпрессию.
2. Disconnect from an atomizer a socket.
3. Turn away the union and disconnect a gasoline pipe line (or disconnect a hose).
4. Turn away 2 screws and get an atomizer.
5. Installation is carried out upside-down.
The thermorelay
6. On the cooled down engine turn away a stopper of a mouth of a tank.
7. Disconnect from the relay a socket.
8. A face key turn out the relay and immediately to prevent liquid loss, wrap the new relay.
