Motoring observation-disclosures a five
passenger car use more gasoline in car
rylng two passengers than it does in
carrying five passengers? Docs it use
more oil? II SO. what would the aver
age be II the car was used but once
week and only then for about so
miles? WIN it injure the tires OF a
car when standing idle, car being
used only once a week?

| A car must, Of necessity, use more
gasoline carrying five passengers in
stead OF two, but the difference would
be 80 slight as to be negligible. The
same answer applies to the oil. but
1t would be almost impossible to meas
lire 1t. The tires would not be dam
aged at all unless they stood In one
spot for several months
! Motoring Department. have a new
1916 Ford, bought last June. 1t does
not run more than II or IL miles on
gallon of gasoline il pleasure driving.
Can you suggest what might be
wrong! G. c.
Either the spray nozzle needs ad-
1ustlng or there is a deftc in it max
ing IL impossible to adjust correctly
Try turning down the spray nozzle
adjusting valve, while the engine is
running, until the carburetor back
tires or the motor slows down appre-
CINE runs best. IL this does not in
crease the mileage have the carbure
tor inspected at service station.
Motoring Department. respectfully
i request to know through your columns,
providing the answers are not to obvi-
Gus to admit your space: % The dif
ference in meaning between expansion
and compression; (2) if the radiator is
for cooling the cylinders, at what at
mospheric low temperature would a.
radiator be practically unnecessary?
f. NJ
Cd One is Just the opposite OF the
other. On the compression stroke the
piston goes upward and both valves
are closed. This congresses the mix
ture into the combustion space at top
OF cylinder. AS crank goes over dead
center the spark sets fire to the COM
pressed gas. The gas burns and ex-
pands, pushing the piston down as it
does So thus producing power. These
two strokes are called the compression
and power strokes respectively. (2)
The air cooled engine has demonstrat-
ed that no radiator is necessary at any
time. 1t, of course, has radiating
, flanges and is cooled by a rush Of air
blown by a fan. If the flanges were
removed greater rush of air would be
, necessary. Even at zero temperature a
. motor would overhead If there we're no
rush of air to carry away the heat.
/ Motoring Departmental have a 1914
Ford which gives me great deal Of
trouble with oil working through TO
piston. The plugs become saturated
! with oil SO that they will not work. l
have had new rings put in to no effect.
Had oversize rings put in, but would
not answer purpose. Had new pistons
put in, and it was all the same. | would
like to know If this trouble can be
remedied. and II So how? The water
in radiator also boils after running six
or seven miles. w. r.
II oversize piston rings have not
