Improvements in Apparatus for use in connection with Engines
Operated by Gas Generated from Petroleum or other Liquid
Hydrocarbon.
We, JULES DHEYNE, Mechanical Engineer, of Schaerbeck, and COUNT DE
NYDPÜRCK, Gentleman, of 5 Rue Van Orley, Brussels, and FREDERIC DE LA HAULT,
Banker, of 154 Rue Royale, Brussels, all in the Kingdom of Belgium, 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 operated by gas generated from petroleum or
other liquid hydrocarbon wherein it is necessary to submit the portions of the
apparatus wherein the gas is generated from the petroleum or other liquid hydro-
carbon to very high temperatures.
The invention is more particularly applicable to gas generating coils arranged as
described in the Specification of Letters Patent No 11459 granted to us and dated
the 17th day of July 1889 and in the Specifications of our applications for Letters
Patent No. 5933 dated the 18th day of April 1890 and of even date herewith.
In the use of these coils it has been found that when the usual metals such as iron
or ordinary copper are used for the making of these coils the high heat to which
they have to be subjected in order to generate a gas suitable for use in the making
of the explosive mixture the said usual metals are subjected to considerable oxidation
or corrosion and the corroded portions or oxides formed become separated and thus
the coils become rapidly deteriorated and unfitted for use whilst the corroded
portions or oxides which form on, and become detached from, the interior of the coils
are very detrimental and injurious to the apparatus, blocking, or contracting, the
passages and being carried into the cylinder and other parts of the engine and causing
injury thereto. After considerable experiment and investigation it has been found
that either nickel (which should be pure) or an alloy of copper and tin in, or about,
the proportion of 67 parts of copper to 33 parts of tin (constituting what may be
termed a yellow copper) will withstand the action of the high temperature satis-
factorily without the corrosion or oxidation and consequent objectionable results
herein before referred to. The said nickel or alloy of copper and tin can be used for
any of the parts which are subjected to the high temperature of the gas generating
portions of the apparatus and wherein the oxidation or corrosion referred to is
objectionable. For instance the whole of the parts situated in proximity to the gas
generating flame may be so made or the coils alone may be so made; or if desired
only that coil in which the gas is generated for use in the explosion chamber of the
engine cylinder may be so made.
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
In, or for use with engines operated by gas generated from petroleum or other
liquid hydrocarbon a gas generating coil or coils, or parts forming, or in proximity
to the gas generating appliances, made of nickel or of a yellow copper consisting of an
alloy of copper and tin in, or about, the proportions hereinbefore indicated.
Dated this 1st day of October 1890.
