COMPLETE SPECIFICATION.
An Improved Oil or Gas Motor.
I, OTTO LUDWIG PHILIPP SWIDERSKI, of Leipzig-Plagwitz in the German
Empire, Engineer and Machine Manufacturer 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 engines which are driven by the combustion of heavy
oils mixed with air in the form of finely divided sprays. The object of the inven-
tion is to insure a more perfect combustion of the inflammable mixture without the
formation of soot. This object has hitherto been rendered difficult of attainment
by reason of the comparatively small size of the combustion chamber in which for
the purpose of the intimate mixing together of the air and oil these latter must
have a high velocity, owing to which a quantity of the oil particles are thrown
against the wall of the combustion chamber before they are reached by the flame.
The central velocity of the spray within the combustion chamber is greater than
that at which the flame is propagated but as the size of the combustion chamber
cannot well be increased in view of the utility of high compression of the air of
combustion the former difficulty remains. The invention consists in a construction
of the combustion chamber of oil or gas motors with two spraying tubes or nozzles
leading into the combustion chamber, the one diametrically opposite to the other,
whereby the energy of the one spray is destroyed by that of the other, so as to
bring the inflammable mixture nearly to a state of rest at a point between the two
spraying nozzles, and form a compact body in form corresponding to that of the
combustion chamber.
In the accompanying drawing
Figs. 1 and 2 are sectional views of so much of an oil engine as is sufficient to
illustrate the invention.
a is the combustion chamber. 6, 6³, nozzles arranged diametrically opposite each
other. c, c, respectively the oil and air supply pipes. d the inflammable mixture
in the middle of the combustion chamber.
In Fig. 1 the spray from each nozzle is composed of oil and air. In Fig. 2 this
arrangement is modified in that the mixture of oil and air is delivered into the
combustion chamber at e in the form of spray and air only at f, through a tubular
channel.
The ignition of the inflammable mixture is effected at 9 by means of an electric
spark or other known means. The body of finely divided inflammable spray is
formed at the end position of the piston as shewn, when the spray is in a compressed
state.
In this way the charge is completely consumed without the formation of soot.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In oil or gas motors the arrangement in the wall of the combustion chamber
of two spraying nozzles or tubes by which the sprays issuing therefrom at the end
position of the piston are caused to meet each other, so that the energy of the one
spray is destroyed by that of the other and so that the greater quantity of the oil
particles come to rest in the middle of the combustion chamber, for the purpose of
producing a steady compact flame substantially as described with reference to Fig. 1
of the drawing.
2. The arrangement of one spraying nozzle for inflammable mixture and one

the purpose specified, substantially as described, and shewn in Fig. 2 of the
drawing.
