Check of system of catching of vapors of fuel

Fig. 2.223. Scheme of check of system of catching of vapors of fuel



Disconnect a vacuum hose from the case of a butterfly valve and connect the manual vacuum pump to a vacuum hose.
Check depression on the specified power setting when the engine cold (temperature of cooling liquid of 60 °C or below) and when the engine is heated-up (temperature of cooling liquid of 80 °C or above).

Check of an adsorber
Check pipelines of system of catching of vapors of fuel for lack of weakening of connections, sharp excesses or damage.
Check lack of deformation, cracks and leak of fuel.

Fig. 2.224. Adsorber


After removal of an adsorber check it for lack of cracks and deformation (fig. 2.224).
Check of the electromagnetic valve of a purge of an adsorber

NOTE
At a detachment of vacuum hoses always previously you put adjusting tags that at connection hoses were established in a starting position.

Disconnect a vacuum hose from the electromagnetic valve of a purge of an adsorber.
Disconnect the socket of a plait of wires from the electromagnetic valve.
Connect the manual vacuum pump to the union of the electromagnetic valve from which the hose with a red strip was disconnected.



Fig. 2.225. The scheme of check at a connection / detachment of power supply from the rechargeable battery to conclusions of the electromagnetic valve


Create depression and check operation of the valve at a connection / detachment of power supply from the rechargeable battery to conclusions of the electromagnetic valve (fig. 2.225).

Fig. 2.226. Measurement of resistance between conclusions of the electromagnetic valve


Measure resistance between conclusions of the electromagnetic valve (fig. 2.226).
Electromagnetic valve of a purge of an adsorber: winding resistance – 26 Ohms (at a temperature of 20 °C).
