Improvements in or relating to Gas Motors.
A cominunication from EMIL CAPITAINE, of Berlin, in the German Empire, Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows:-
The present invention relates to gas motors in which preferably petroleum is
introduced and atomized and converted into gas, and the combustible mixture then
compressed and ignited; and the object of the invention is to convert the atomized
petroleum into gas on the comparatively small surfaces of the combustion chamber, to
avoid the contact of the atomized oil with those walls or surfaces which have been
cooled, and to mix the gas obtained intimately with the air.
The peculiarity of the present invention consists essentially in the form of the jet of
air and atomized oil introduced into the combustion chamber which also is formed in
such a manner as to permit a uniform moistening or sprinkling of the whole of
its surface.
While in the atomizers used up to the present the jet was straight and full, in this
arrangement the jet is hollow and extending or funnel shaped and the walls of the
combustion chamber are formed in such a manner that no particles of the atomized
oil reach the cylinder, but that the hot walls of the combustion chamber are almost
uniformly moistened or sprinkled with the atomized oil and that the air following
takes up and mixed with the gas produced.
.
The angle at which the atomized oil enters the combustion chamber depends upon
the conical form of the valve and the valve seat, and must be adjusted according to
the shape of the combustion chamber which in the case of a motor with long stroke
and small cylinder diameter would be rather flat and elongated, and in a motor with
a short stroke and large cylinder diameter would be rather round and short.
The peculiar construction of the valve and seat serves to protect the valve against
becoming damp and lamp-black settling thereon.
The oil distributor is annular in shape and has a fine annular slot through which the
oil escapes. An annular current of air passes around the oil distributor with great
velocity and atomizes the oil which is extended by a current of air passing on the
inner side of the oil distributor and impinging against the circular and slightly
conical valve extends laterally and with it the circular jet of the atomized oil.

A communication from EMIL CAPITAINE, of Berlin, in the German Empire, Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.,
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:
The present invention relates to gas motors in which preferably petroleum is intro-
duced and atomized and converted into gas and the combustible mixture then
compressed and ignited; and the object of the invention is to convert the atomized
petroleum into gas on the comparatively small surfaces of the combustion chamber,
to avoid the contact of the atomized oil with those walls or surfaces which have been
cooled and to mix the gas obtained intimately with the air.

page_text: The peculiarity of the present invention consists essentially in the form of the jet
of air and atomized oil introduced into the combustion chamber which also is formed
in such a manner as to permit a uniform moistening or sprinkling of the whole of its
surface.
While in the atomisers used up to the present the jet was straight and full in this
arrangement the jet is hollow and extending or funnel shaped and the walls of the
combustion chamber are formed in such a manner that no particles of the atomized
oil reach the cylinder but that the hot walls of the combustion chamber are almost
uniformly moistened or sprinkled with the atomized oil and that the air following
takes up and mixes with the gas produced.
The angle at which the atomized oil enters the combustion chamber depends upon
the conical form of the valvo and the valve seat and must be adjusted according to the
shape of the combustion chamber which in the case of a motor with long stroke and
small cylinder diameter would be rather flat and elongated and in a motor with a
short stroke and large cylinder diameter would be rather round and short.
The peculiar construction of the valve and seat serves to protect the valve against
becoming damp and against an after evaporation and consequent settling of lamp
black thereon.
The oil distributor a is annular in shape and has a fine annular slot a through which
the oil escapes. An annular current of air as indicated by the arrow passes around
the oil distributor a and circumference with great velocity and atomizes the oil
oozing through the slot this spray being then extended by a current of air as
indicated by the arrow y passing on the inner side of the oil distributor and impinging
against the circular and slightly conical valve, extends laterally and with it the
circular jet of the atomized oil which is prevented from impinging on the surfaces of
the valve and valve seat by being interposed between the two streams of air.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what claim is ;-
1. The introduction of the atomized explosive mixture in a round wide spreading
stream and the formation of the combustion chamber to correspond so that the
particles of the explosive mixture strike upon the whole of the interior surface at
or about the same time substantially as herein described.
2. For the production of the above mentioned wide spreading ring-shaped hollow
stream the atomizer by which the oil enters through a fine annular opening such
as a and between the two currents of air which pass between the valve-box and the
oil-distributor the oil being so surrounded that a moistening of the valve and the
valve-seat can be prevented substantially as described.
