An Improvement in Oil Engines.
I, PIERRE GODEFROY ARMAND PEUGEOT, of Valentigney, (Doubs), France,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved oil engine and has for its main object to
enable the engine to be governed by regulating the supply of oil to the oil spraying
chamber of the carburator with which object a centrifugal governor is mounted on
the main shaft and acts through a lever on a valve controlling the supply of oil
to the chamber wherein the oil is converted into spray and inhaled along with air
into the working cylinder, so that when the speed of the engine becomes excessive
the supply of oil is cut off, the engine inhales only air, no explosion takes place,
and the speed is reduced until on again becoming normal the supply of oil is
renewed.
The engine has two parallel cylinders placed side by side and having their
pistons coupled to cranks which may be in line or at 90° or 180° to one another and
between which is mounted a cylinder cam having a peripheral reversed spiral cam
groove for governing the distribution of explosive mixture to the two cylinders.
The valve chambers of the two cylinders may either be quite separate or be con-
tained in one casting comprising the two compression chambers and the two
chambers for the admission and exhaust valves. The admission valves are self
opening whilst the exhaust valves are opened alternately, each once for every two
revolutions, by a rock shaft operated by the reversed spiral cam groove and having
arms which act directly upon the valve spindles.
The carburetter comprises an oil regulating chamber containing a float acting
on a supply valve beneath it through the medium of any suitable device such as
levers, whereby when the float falls the valve is opened so as to maintain a constant
level in the chamber and also an oil spraying and carburetting chamber alongside
the supply regulating chamber and having a mouth open to the admission of air.
The oil passes from the lower part of the regulating chamber to a nozzle having
one or more orifices and leading into the carburetting chamber whence the oil
is projected in a fine stream or streams across the air inlet passage of the car-
buretting chamber so that it meets at right angles the current of air drawn there-
through by the inhaling stroke of the piston whereby the oil becomes pulverized
by the shock and becomes intimately mixed with the air which may or may not
have been previously heated. At the lower part of the carburetting chamber is a
division or divisions formed of wire gauze inclined at about 45°, through which
the air must pass and upon which any oil not immediately taken up by the air
must fall so that the air in traversing the meshes of the gauze will become saturated
with oil and form carburetted air which passes from the carburetting chamber to
the admission valve chambers of the engine.
The oil passage leading from the regulating chamber to the spraying nozzle is
controlled by a governor valve which is opened by a spring and closed by the
action of a centrifugal governor upon the engine shaft within the crank chamber,
the action of the governor being transmitted through a collar sliding on the shaft

page_text: and connected by a rod sliding through the journal bearing with a lever having a
spring arm acting directly upon the stem of the governor valve so that when the
governor balls fly out the valve is closed and interrupts the passage of the oil to
the spraying nozzle so that the engine inhales only air and explosions cease until
the normal speed is regained.
This means of governing may also be applied to other forms of engines than that
described and may be modified to suit the circumstances of the case.

I, PIERRE GODEFROY ARMAND PEUGEOT, of Valentigney, (Doubs), France,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:_
This invention relates to an improved oil engine and has for its main object to
enable the engine to be governed by regulating the supply of oil to the chamber
wherein the oil is converted into spray and inhaled along with air into the working
cylinder so that when the speed of the engine becomes excessive the supply of oil
is cut off, the engine inhales only air, no explosion takes place, and the speed is
reduced until on again becoming normal the supply of oil is renewed.
Reference is to be had to the accompanying drawings wherein Figure 1 is a longi-
tudinal section of an engine and of the carburetter. Figure 2 is a plan of the
same, the carburetter being in section. Figure 3 is a detail view of the lever
actuating the exhaust valves. The same leters indicate the same parts in all the
figures.
The engine has two parallel cylinders placed side by side and having their pistons
coupled by connecting rods ab to cranks which may be in line or at 90° or 180
to one another and between which is mounted a cylindrical cam c concentric with
the crank shaft and revolving therewith and having a peripheral reversed spiral
cam groove for effecting the distribution of explosive mixture to the two cylinders.
d is the fly wheel. The valve chambers of the two cylinders may either be quite
separate or be contained in one casting comprising the two compression chambers
and the two chambers for the admission and exhaust valves. The admission
valves e are self opening whilst the. exhaust valves e¹ are opened alternately, each
once for every two revolutions, by a rock shaft g operated through an arm h and
slide block by the reversed spiral cam groove the rock shaft g having arms f
which act directly upon the valve spindles.
The carburetter comprises an oil regulating chamber j containing a float acting
on a supply valve beneath it through the medium of any suitable device such as
levers whereby when the float falls the valve is opened so as to maintain a constant
level in the chamber j and also an oil spraying and carburetting chamber k along-
side the supply regulating chamber and having a cover and an open mouth m
for the admission of air. The oil passes from the lower part of the regulating
chamber through a channel n to a nozzle o having one or more orifices and leading
into the air inlet passage of the carburetting chamber from which nozzle the oil
is projected in a fine stream or streams across the said passage so that it meets at
right angles the current of air drawn therethrough by the inhaling stroke of the
piston the oil becoming pulverized by the shock and intimately mixed with the air

page_text: which may or may not have been previously heated. At the lower part of the
carburetting chamber is a division or divisions q formed of wire gauze inclined at
about 45° through which the carburetted air must pass and upon which any oil
not immediately taken up by the air must fall so that the air in traversing the
meshes of the gauze will become saturated with oil before passing from the car-
buretting chamber to the admission valve chambers of the engine to which the
outlet p of the carburetting chamber is connected.
The oil chamber n leading to the spraying nozzle is controlled by a valve r
which is opened by a spring w and closed by the action of a centrifugal governor
upon the engine shaft within the crank chamber, the action of the governor being
transmitted through a collar s sliding on the shaft and connected by a rod sliding
through the journal bearing with a lever t pivoted at u and having a spring arm v
which acts directly upon the stem of the valve r so that when the governor balls
fly out the valve r is closed and interrupts the passage of the oil to the spraying
nozzle so that the engine inhales only air and explosions cease until the normal
speed is regained.
It is to be understood that the spraying and carburetting chamber may be other-
wise arranged, for instance the oil may be projected vertically and the air enter
horizontally.
The above described means of governing may also be applied to other forms of
engines than that described and may be modified to suit the circumstances of the
case.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The herein described oil engine characterized by the application of a special
means of governing, consisting of a centrifugal governor mounted on the engine
shaft and operating a lever which acts on the valve which regulates the supply of
oil to the spraying chamber of the carburetter substantially as specified.
2. The herein described means of governing an oil engine, consisting in the
combination, with an air. carburetter, of a spraying nozzle for the oil, a valve to
control the supply of oil thereto, a centrifugal governor actuated by the engine
shaft and acting through a lever on the valve by which the supply of oil to the
carburetter is controlled substantially as specified.
