COMPLETE SPECIFICATION.
Self-heating Vaporiser for Mineral Oil Motors.
We, PHILIPP SWIDERSKI and JOSEPH AUGUST SCHWICKER, both Directors-
of the Leipziger Dampfmaschinen und Motoren Fabrik, of Leipzig-Plagwitz,
Germany, 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 has for object to provide means for driving mineral oil motors.
without the use of a heating lamp or electric igniting device.
In the accompanying drawing Fig. 1 is a sectional view of the vaporiser of this
invention shewn in connection with a spraying valve Z and with the explosion.
chamber E of a petroleum motor, and this figure also shews the vaporiser in end
elevation without the cover.
The vaporiser consists of a casing K always in open communication with
the cylinder of the motor, in which casing is inserted the vaporising organ V
having a central bore B, closed at one end, in the longitudinal axis of the
vaporiser and concentrically surrounded by a number of circular passages b
extending through the whole length of the vaporising organ V.
The operation of the self heating vaporiser is as follows:-The petroleum mist
or spray coming from the spraying valve Z and drawn through the small tube r
arranged in the longitudinal axis of the vaporiser strikes against the front end of
the vaporising organ V and then flows equally distributed through the bores or
passages 6 to the side of the cylinder, whereupon vaporisation takes place, by
reason of the contact with the large heating surface. Here the petroleum vapour
now collects to pass through the tube m of the explosion chamber E and be carried
along with the current of air drawn through the suction valve A. In the com-
pression of the charged mixture one portion of the same is forced into the
vaporiser to be there ignited at the hot surfaces of the vaporising organ V and
thus bring about the explosion. As the casing K-protected against radiation.
of heat by an asbestos covering-is in constant open communication with the
explosion chamber, and consequently the vaporising organ V impinged upon
around its surfaces, during the explosion period, by the hot gases of combustion,.
a certain amount of heat will during said period be communicated to the vaporising
organ V which suffices to effect the vaporisation of the petroleum and also the
ignition of the mixture itself even when the motor is running empty.
At first, for the purpose of starting the motor, the vaporiser must be heated
from the outside to a sufficient temperature by means of a lamp of any suitable-
kiud.
The casing K as well as the vaporising organ V may be of any suitable form to
be determined by the particular requirements. Different forms of vaporising-
organs are shewn in Figs. 2 to 6.
Having now particularly described and ascertained the nature of our said inven--
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A self heating vaporiser for mineral oil engines characterised by a casing K in
constant open communication with the explosion chamber, and having inserted in
it a vaporising organ V of any suitable form, which vaporising organ is during the-

page_text: explosion period, impinged upon by the gases of combustion and there with heated
in order, upon the immediately following suction period, to vaporise the petroleum
spray or mist serving for the mixture, and after compression, ignite the charge, for
the purpose of rendering superfluous the external heating of the vaporiser during
the working of the motor, substantially as described and shewn.
Dated this 27th day of October 1896.
