EVAPORATIVE LOSS CONTROL
To
sliminote fuel vapourisation into the atmosphere, and thus comply W :+h ' jerol
Motor Vehicle Safety Standards, an 'evaporotive circuit' is incorporated in'
the fuel
system of cars fitted with Zenith carburetters.
This
'eve :motive circuit' consists basically of an activated charcwl canister which
collects the fuel vapour given off from the
frrel tank vents or the filler neck:
0
Mounted alon
g
side the fuel tank is o catch tank, for the purpose of prever
neot'
fuel reaching the chorcoal canister, under conditions of extreme heav
,r biolent
vehicle manoeuvres. The catch tank cannot receive petrol via the filler necks of :he
main tank. Petrol vapour obsorbed by the charcwl canister is Ipurged1 by clean air
while the engine
is running, through throttle edge drillings in the corburetters.
The system
is effectively maintained by renewing the charcoal canister at intervals
of every
25,000 miles (or 40,000 km).
