as 10 the benefit gained in cleaning
out the lubricating oil at regular in
tervals and rehlling with fresh oil.
Thanking you in advance, l am,
Mr.
The benefit derived from regular
ly cleaning out the lubricating oil
and reflling with clean oil viii .
lengthen the life Of the engine and .
cannot be too highly recommended.
Motoring Department, The News
Times Kindly explain what is an
automatically advanced ignition and
how il is accomplished? /. NJ.
In place. of a hand operated spark
lever on the steering wheel there is
a centrifugally operated device incor-
porated with the timer or distribu-
tor. As this depends upon the speed
Of the engine, the ignition timing is
always at the point Of extreme retard 4
when the engine is stopped. The de- /
vice is a small centrifugal governor, !
/ the weights of which expand against |
the action OF a spring under the in
Z fluence Of increasing speed.

gines been abandoned. Respectful /

/ The make and break system" of
ignition has not been used on any
standard stock automobile engines
since 1909.

| Times. / am anxious to learn wheth-
er motors are ever drilled to permit
| the escape OF the burnt gases
| through the sides of the cylinder, be-
sides using the exhaust valve. and
why is this done? r. S.
! In exceptional cases the cylinders
/ of high speed engines have been
/ drilled at the depth of the piston |
stroke to allow the exhaust TO es- |
cape so that the pressure exerted !
on the piston on its upward stroke !
would be greatly reduced. This was
done to gain greater efficiency for !
the engine.

Times Kindly let me know whether |
a magnetic can be run in either di- !
rection. and oblige. D. G.
Owing to the contour of the cam
which serves to open the contact
points the magnetic is made to turn
Iclockwise. or counter clockwise. and
/ is known as either a right-hand or
left-hand machine.

| Times: Some years ago / saw al the
automobile show magnetic spark
plugs, and would like TO know why
they never became popular. Thank
/ ing you in advance. J. ID. II.
! The reason for the magnetic
spark plug not becoming popular is
| because it seldom withstands the
heat of the engine for any length of
! time. so that the insulation fails.
! Apart from this, the troubles encOun-
tered are the same as with any sys-
/ tenn having movable contacts.

Times. I just had the engine of my
car cleaned and two leak proof pis-
I ton rings put in each piston, one
on top and one on bottom OF each
I piston and since this has been done
] 1 notice il gives a terrible lot Of
smoke when in low and second. but
Y is all right when running in high.
IL did not smoke before it was
| cleaned, etc. Still il has more pep
and power than I believe it ever has
had, up hills and through sand. Com
/ preston seems good. Does this
mean any of my rings are leaking?
/ The garage man who worked on the
car says I am putting too much oil
in same, yet no more than I carried
before. Ny car is a 1917 Dodge. AL
so 1 have what is called noisy gear,
luntil / pass the 20-mile speed. Have
been told 20 put cork in. But have
also been told that cork would be
liable TO injure the gears and would
stop the noise only for a short time.
Answers 20 the above will certainly
be appreciated. Valves were also
ground. Have been running the car
only a few days since it has been
worked on.
The increase in power you mention
seems TO Offset the possibility of
leakage past piston rings and ii
seems more likely that the oil you
are using is too light Cork Will only
temporarily relieve the grinding of
the gears. and it may damage the
parts.

that by emptying out the solution in
a storage battery il would keep all

Kindley let me know if this is the
case. W. 3.

battery il may either be stored wet
or dry. The wet method is usually
applied when a battery is put out
