1t is not likely that your trouble is

buretor TO give richer mixture. The
gasoline flow, due to the low position

pint directly In front and slightly
above the carburetor. This tank ,is
merely connected in the line, has no
valves and is only reservoir, but with
suficient capacity to carry the car
over the longest hills, even though the
supply of fuel were cut of.
Can YOU give me some information
as TO automobile valve timins3
The timing of a motor depends on
whether the greatest torque or twist
! ing effort is wanted at low OF high
speeds and whether 1t Is desirable to
have a silent motor. For instance, IL
motor with q particularly good torque
at low speed is wanted, then the ex-
shaust opening should be delayed more
than usual so that the expansive force
fof the gas will be exerted to the ut
most. On the other hand, If the motor
lis to develop maximum torque at q
high speed it is better to open the ex-
ilaust valve earlier so us to give the
gas plenty OF time to flow out The
reduction In hack pressure due to this
more than compensates for the small
amount OF expansive energy that is
| thus thrown away.
Exhaust closure should occur at dead
center or slightly after. On a slow
speed motor it would be all right to
clos the exhaust valve right on dead
center, but lie this were done on q
motor that had a maximum speed OF
say 1000 revolutions or more the
lscavenging Of the. cylinder would not
be as complete as If the closing We're
DELAYED few degrees. The reason for
this is simple. When the gas Is HOW
/ ing out through the exhaust valve Mt
the high speed that Is obtained when
| the motor is running mt this rate 1T has
| perceptible amount OF momentum, Ill
though its actual mass Is very small.
Therefore the tendency is for the
! column of gus to keep on flowing when
the piston reaches upper dead center
I, This action naturally helps to suck out
| n little gas after the piston has ceased
to force it out.
The opening of the inlet vnlve should
take place shortly after the exhaust
valve closes. its exact point of opening
depending on whether the designer
considers IT best to begin to fill tile
cylinder with a rush. In the former
case the valve is made to open 4 at
about top deadscenter and in the latter
case the opening is delayed possibly as
much as twenty degrees. If the open
ing, IS delayed a partial vacuum Is
formed in. the. cyHnder, due TO the fact
| that the piston moves out and expands
the gas below atmosphere: Then when
(, the inlet valve is finally opened the
charge PUSHES in to fill this vacuum.
| This action Is believed to give better
carburetion by a great many design
ers. The closing of the intake valve,

ends on the speed of the motor. II
