PROVISIONAL SPECIFICATION.
Petroleum Motor.
I, OSCAR BRÜNLER, of Eutritzsch-Leipzig Braustrasse 15 in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is a contrivance as shown by the enclosed
drawing, for the gasification of the petroleum, and for the ignition of the petroleum-
gas-mixture and of the air in petroleum-motors working with four-times motion.
The cooled compression-space a is continued by the passage al in the wall of
which a plate f, curved to the outside and heated from outside to red heat is
inserted.
Immediately before, or at the beginning of the suction-period, a pump conveys a
measured quantity of petroleum through the pipe and the passage g into the
passage a', the petroleum being dispersed and immediately evaporated at the red
hot plate f. The air sucked through the valve e, drives the gases to the compression
space a, without being able-on account of its great velocity-to enter the hollow
plate. During the compression, the mixture formed in the meantime, is driven
back into the passage a' the spaces being proportioned so that at the end of the
compression the inflammable mixture reaches the red-hot plate f, effecting the
explosion which throws down the piston. If the plate f, instead of being curved
to the outside were curved to the inside, or if it were a straight continuation
of the passage-wall, a combustion of the mixture would take place already during
the suction-period. As it is, the air passes inside, without touching the red-hot
plate f.

Petroleum Motor.
I, OSCAR BRÜNLER of Eutritzsch-Leipzig, Germany, 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 :-
The object of the present invention is a contrivance as shown by the enclosed
drawing, for the gasification of the petroleum and for the ignition of the petroleum-
gas-mixture and of the air in petroleum-motors working with four-tact motion.
The cooled compression-space a is continued by the passage a in the wall of
which a plate f, curved to the outside and heated from outside to red heat is
inserted.
Immediately before, or at the beginning of the suction-period, a pump conveys a
measured quantity of petroleum through the pipe and the passage g into the
passage a', the petroleum being dispersed and immediately evaporated at the red
hot plate f. The air sucked through the valve e, drives the gases to the compression-
space a, without being able-on account of its great velocity-to enter the hollow
plate f. During the compression, the mixture formed in the meantime, is driven
back into the passage a' the spaces being proportioned so that at the end of the
compression the inflammable mixture reaches the red-hot plate f, effecting the

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 :
In a petroleum motor the combination of the passage a being a continuation of
the compression space a, the hollow plate f which is heated from outside and the
passage g for dispersing the petroleum, as and for the purpose set forth.
Dated this 20th day of May 1893.
