So, in the engine compartment, there is an adsorber for the fuel vapor recovery system: 1 – adsorber; 2 – electromagnetic valve for purging the adsorber; 3 – connecting hoses.
This subsystem is used in the feedback injection system. It uses a method of vapor capture with a carbon adsorber. It is installed in the engine compartment and is connected by pipelines to the fuel tank and throttle assembly. On the adsorber cover there is an electromagnetic valve, which switches the operating modes of the system according to signals from the control unit.
Fuel vapor recovery system components (adsorber, adsorber purge valve) removed for inspection or replacement if a persistent smell of gasoline appears, caused by leaks in the units and pipelines, as well as failure of the purge valve of the adsorber. In addition, a violation of the tightness of the adsorber and a failure of the purge valve can cause unstable engine operation at idle speed up to a stop.
1. To replace the purge valve, disconnect the wiring harness connector from the valve…
2. … loosen the clamps securing the vacuum and purge hoses and disconnect them, after marking them so that they can be installed in their original locations.
3. Press the plastic holder with a screwdriver…
4. …and remove the purge valve.
