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. |
