Improvements in Petroleum Engines.
1, WILLIAM DE COURTNEY, in the firm of Huelser & Co., of Temple Chambers,
London, International Patent and Trade Mark Offices, do hereby declare the
nature of this invention, a communication to me from abroad by Oscar Brüenler,
Engineer of Eilenburg, Germany, to be as follows :-
-
This invention relates to improvements in petroleum engines and has for its
object to cause a portion of the air supply to pass through a suitable tube,
diffuse the petroleum admitted therein and carry the same into the explosion
chamber.
In carrying my invention into practice, I arrange between the air inlet valve of
a petroleum engine and the combustion chamber a valve which has for its object to
so throttle the air on its way to the explosion chamber as to cause a portion thereof
to pass sideways through a curved pipe connected to the explosion chamber and to
which leads the petroleum supply pipe, this air diffusing the petroleum on its way
to the explosion chamber wherein it is ultimately conveyed.
The air supply valve is situated above the cylinder, and the lateral pipe is bent
at 180°, the lower end communicating with an evaporating pipe which leads to the
space situated between the said throttle valve and the combustion space. The
lower end of the lateral pipe has a cavity for the reception of the petroleum
supplied from below.
Or the lateral pipe may be horse-shoe shaped and serve as evaporator, so as to
dispense with a separate evaporating pipe. In this case the petroleum is supplied
to the inlet end or upper part of the lateral pipe together with the air, through a
nozzle. The base of the nozzle communicates with the air inlet and contains the
small cavity or collecting chamber for the petroleum entering from below.
air current flowing to the nozzle is deflected by a block or plate, so as to come into
close contact with the petroleum.

Improvements in Petroleum Engines.
I, WILLIAM DE COURTNEY c/o Huelser & Co. of Temple Chambers, London,
International Patent Agency do hereby declare the nature of this invention, &
communication to me from abroad by Oscar Brüenler, Engineer of Eilenburg,
Germany, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of this invention is a contrivance represented by the accompanying
drawings, in which
Fig. 1 is the section of the respective portion of the cylinder of a petroleum
motor.
Fig. 2 represents a modified arrangement.
This device has for its purpose to utilise the air-current, which is drawn by suction
into the charge chamber for forming the mixture, at the same time for diffusing the
petroleum and for introducing the same into the evaporator. With the suction
stroke, valve b opens, and air enters into the combustion chamber. According to
the position of the throttle valve c a greater or smaller portion of the drawn-in air

evaporator g located below the throttle valve c and terminating in the charge
space a of the cylinder. At the curved end of the tube d is provided the inlet e for
the petroleum supplied through tube e and accumulated in the cavity of tube d in
front of the evaporator, and carries this petroleum with it. The throttle valve e
being located above the opening of the evaporator, no diffused petroleum is blown
against the said valve.
For the modified construction shown by Fig. 2 the curved tube d serves at the
same time as evaporator. The channel e through which the petroleum is supplied
is disposed in a short tuble d' connecting the upper end of the tube d to the cylinder.
This tube d is provided with a nozzle and with a block / deflecting the air current
to the cavity f.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
(1.) In a petroleum motor, the arrangement whereby the air supplied through
valve to the charge space for forming the mixture is so throttled by a throttle
valve e as to partly penetrate into tube d communicating with the evaporator, and
press the quantity of petroleum present at f into the evaporator, substantially as and
for the purpose set forth.
(2.) The application of a cavity f in the tube d, as referred to in Claim 1, serving
to receive the liquid fuel, said cavity being in open communication with the
evaporator, substantially as and for the purpose set forth.
