Nozzle of start-up of the cold engine (And) and a thermotimer (In)
Nozzle of start-up of the cold engine (Motronic system)
Check
PERFORMANCE ORDER |
|
1. Check is carried out at engine temperature not above 30 ° by S.Otsoyedinite from a nozzle the socket and take aside. |
|
2. Unscrew 2 screws and get a nozzle, 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. During this time leakages of fuel from a nozzle it should not be observed. Otherwise a nozzle replace. Switch off ignition and clean a crossing point. |
L-Jetronic system |
|
3. Attach the socket to a nozzle and substitute under it a vessel. Ask the assistant to include ignition and a starter. The stream of a conic form should be observed. If a stream faltering, clean a nozzle or replace. |
|
4. If the stream is absent, check tension on the socket at starter inclusion. If tension is not present, replace the thermorelay. |
|
Thermotimer (relay of a starting nozzle)
The thermotimer operates a nozzle of start-up of the cold engine, providing opening of a starting nozzle for a certain time which depends on engine temperature. The relay is mounted near the sensor of temperature of liquid. Check is carried out at engine temperature not above 30 ° by Page.
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 black yellow wire of the socket. |
2. For this purpose ask the assistant to include ignition and a starter. Tension should appear at the moment of inclusion of a starter and later 6–10 seconds, depending on engine temperature, disappear. |
|
3. If tension is, open the socket check short circuit of contacts of the relay. |
4. Attach a wire of the coil and warm up the engine to temperature not below 41 ° S.Kontakty the relay should be opened. Otherwise the relay replace. |

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