EVAPORATIVE EMISSION
CONTROL SYSTEM
Dependinguponthemarketforwhichthevehicle
is destined,  the  emission control  system will
comprise one or more of the following emission
control devices.
The Evaporative  Emission Control  System is
designedtopreventfuelvapoursfromescaping
into the atmosphere through the fuel tank venti-
lation system.
Whilst the engine is  not running, fuel vapours
generatedinsidethefueltankareabsorbedand
storedinacharcoalcanister.Whentheengineis
started, the vapours stored in the  canister are
drawn into  the  induction system  through the
purge control  solenoid  valve and  are subse-
quentlyburned.

the canister.  Under normal running conditions
when the engine is warm, the valve opens and
the vapours are  drawn into the inlet  tract and
subsequently burned in the combustion cham-
ber.

that care is exercised  to prevent damage, the
catalyst will operate efficiently for the life of the
vehicle.
