How is the wheel base of a car meas
ured?
The wheel base OF n car Is the dis
lance between the center Of the hui
caps on one side Of the car.
What are the advantages and disad-
v~antages Of an undersIuns carr
The most important feature OF a car
with an underslung frame is that the
center Of gravity is lowered, which In
creases It's stability. Turns may be
taken at greater speed than with cars
whose center Of gravity Is higher,
which makes the undcrslung car a safe
one In this respect. 1t is claimed that
this construction reduces side sway con
siderably and forms an easier riding
car than one with an o~verhung frame.
When an underslung frame is used a
raised auxiliary frame Is used for sup
porting the motor, and In nearly all
cases the construction tends toward II
straight line drive. Cars with under
slung frames require large wheels and,
hence, large tires. The makers OF over
hung cars have succeeded In lowering
the center Of gravity sufficiently to
make the vehicles as safe as the under
slung type. Nearly all the advantages
Of the underslung arc now In the over
hung. and the cost 10 not 30 great.
Can you tell me how oxygen 10 used
to rsmovs carbon from cylinders? !
have an oxyaoetyisns welding outfit,
but cannot understand what method 10
ussd to start combustion bstvvsen tho
carbon and oxygen, ~ the carbon must
be at q vsry high heat before eombus-
ton will commence.
Il Is suggested that the day before
operation are to begin the engine be
given the conventional kerosene treat
ment. A half tumblerful OF kerosene
n poured into each cylinder and per.
mittsd to remain there overnight As
q prscaution against nre the gasoline
b shut OF from the carburetor and the
motor started so that the fuel In the
line will be consumed. Work u done
on one cylinder at q time. Taking the
nnt cylinder. a cylinder plug Is re-
moved. The motor Is then turned over
until the piston Of that cylinder Is on
top dead center. II the spark plugs
are not removed the points will be-
come burned, so As q p~recaution insert
old plugs.
The outfits on the present market
are fitted with gauges, and these should
be made 10 register about twelve
pounds. The hose attached TO the tank
has at its end an injector tube. This
tube is directed into the cylinder. The
injector is controlled by a valve, in
one case a trigger valve, so as to be
manipulated easily. A lighted match is
dropped into the cylinder and the In
jector tube inserted into the cylinder
and moved around as much az posi-
BILE SO as to cover a large area. The
combustion Of the carbon Is accompa-
MED by sparks ana perhaps a little
fame from any oil with which 1t may
be soaked. Once the carbon begins to
burn the action continues without in
terruption as long as oxygen Is being
supplied. The difficulty with many
has been In getting the initial burning.
The use of burning matches, as before
mentioned, Is good, but many state
that the wax taper Is better. insuring
immediate burning. When the sparks
cease flying the operation Is finished.
1t is advisable after cleaning carbon
to grind the valves, but this should
not be done II the motor compression
is good. A little oil should be poured
into each cylinder and the motor turn
ed over a few times after the opera
ton Is over. because the flame leaves
the cylinder and piston dry.
Can you tell me whether or not an
electromagnetic for recharsing magnetic
magnets can be made to operate by al
current?
An electromagnetic operated by alter
mating current cannot be used for re-
charging magnetic magnets. II a rec
tiier is placed In the circuit between
the line and the electromagnet re-
charging Is possible.
My electric starter does not seem to
have power enough to start the car, and
the lights 90 down unless the car is be-
ing run fast. The storage battery has
recently been o~verhauIed. Can you tell
mo what IL the matter7
1t appears that poor regulation may
be the cause Of your trouble. The bat
terry is not properly charged, and hence
the lights burn dimly and the crank
ing motor does not act we'll. The wir-
ing between the battery and generator
may have been disturbed. resulting In
broken insulation or a periodic open
circuit.
