slightly
while
the
car
is

EF

deceleration

During
deceleration

the

rises
and

the

quan

is

not

suffICient
for

combustion
to

continue

consequently
a

great

amount

emitted

Carburetors

equipped
with

the

supply
the

engine
with

an

adequate
charge
of

combustible

mixture
to

At

Under
