4 PL FUEL SYSTEM

EVAPORATIVE EMISSION CONTROL

SYSTEM :

The car is fitted with an evaporative system to meet all

requirements of evaporative emission.

The system is designed to prevent fuel vapours formed

within the tank and fuel system from escaping into the

atmosphere.Theevaporativeemission systemconsists of :

a) Restrictor

b) Vapour Separator

c) Tank pressure valve

d) Carbon canister

e) Canister Purge valve

a) Restrictor : Fig. 18

The restrictor is welded on top portion of the fuel

tank assy. The restrictor allows the flow of gasoline

vapours only and not liquid fuel in both directions.

b) Vapour Separator : Fig. 19

Theseparator ismadeof highgradeof polypropylene

and is mounted near to the filler neck area on the

rearwheel arch. Avapour liquidseparator allowsonly

liquid free vapour to pass from fuel tank restrictor to

the carbon canister through tank pressure valve.The

vapours getting condensed / liquid fuel goes to the

filler neck.

Removal :

ing slideback the clamps and pull the hoses.

2.Remove quick connector’s joints carefully.

3. Loosen vapour separatormounting screws.

Inspection :

Check for crack or deformation of vapour separator.

Replace if necessary.

Assembly :

Vapour hoses connections varies for each type of

hose. Necessary care to be taken to connect and

clamp each hose correctly. Use suitable tool for

fitment of clamp.

Do not kink or twist hose when they are routed.
