Improvements in Motor Engines Worked by Ether Vapour or other
Volatile Fluids in Combination with a Gas Motor Engine for the
Utilisation of the Waste Heat thereof.
I, PAUL DE SUSINI, of 6 Rue de Sfax, Paris, France, Doctor of Medicine,
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 excellent results which I have obtained with the arrangements of motor
engines worked by ether vapour &c. described in my applications for Letters
Patent bearing equal date herewith in which I effected the combination of a closed
circuit of ether vapour or other volatile fluids, either with a circuit of exhaust
steam from a steam engine, or with a circuit of live steam, supplied by a boiler,
have led me to combine the said closed circuit of ether vapour &c. on the one hand
with the casing of the cylinder of a gas motor engine and on the other hand with
the escape pipe or passage of such cylinder, with the object, firstly, of utilising the
calories that are ordinarily carried off by the cooling water circulating through
the cylinder jacket, and which represent one half of the calories expended; and
secondly, of utilising also the waste heat contained in the discharged combustion
gases, which represent the fifth part of the calories expended.
According to the results which I have obtained with the above mentioned
previous arrangements, I am enabled, when using the present new combination, to
reckon upon a development of power which shall be equal to, more or less, the
double of the power developed by the gas engine itself.
I will proceed to describe my said invention with reference to the accompanying
drawings which shew by way of example one arrangement for carrying the invention
into practice.
Fig. 1 shews a sectional elevation of the complete apparatus, and Fig. 2 shews
a sectional plan. X is the motor engine worked by ether vapour &c. and which is
of the same construction as that described in the Specifications to my said other
applications; Y is the gas motor engine of any known construction, through the
cylinder jacket of which the ether vapour is made to circulate and Z is the ether
vapour generator.
From the cylinder A of the gas motor engine, the combustion gases are discharged
through the pipe B either to the ether vapour engine through the branch pipe a
or to the ether vapour generator through the pipe b, the discharge in the one
direction or the other being controlled by a three way cock c by means of which
also the quantity of gases so conveyed is regulated.
When the gases are conveyed to the engine X they are made to pass from the
pipe a into the jackets D. D. of the engine cylinders E. F., and escape through
the pipe G which, surrounds the supply pipe for ether vapour H leading to the
cylinders E. F in order to prevent condensation of ether vapour therein.
The gases then pass into the chamber 1 of the generator of ether vapour Z where
they give up the remainder of their heat in producing ether vapour, the generator Z
being for this purpose constructed in the same manner as described in my said other
applications. The cooled gases eventually pass off through the pipe J.
Should the combustion gases heat the jackets D to too great an extent, they may
be conveyed partly or wholly through the pipe b to the vapour generator Z by
suitably regulating the cock c. The liquid ether contained in the generator in the
chamber surrounding the small tubes through which the combustion gases pass, as
described in my other applications, passes through the pipe K to the jacket L of
the gas motor cylinder A, where it takes up heat from such cylinder, producing

some ether vapour, which together with the heated liquid ether passes back to the
generator Z through the pipe M.
The ether vapour, after having performed work in the cylinders E and F escapes
through pipe N to a condenser such as described in my said other applications and
whence after condensation, it is drawn through a pipe o to the pump O by which it
is forced back into the generator Z through a pipe o'.
Having now particularly described and explained 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. The combination of a generator of ether vapour or other volatile fluid with
the jacket of the cylinder of a gas motor engine in such manner that the liquid
ether is made to flow through a pipe from the generator to the cylinder jacket and
after circulating through the same is made to flow back to the generator through
another pipe, whereby the liquid ether is made to take up heat from the cylinder
so as to cool it and at the same time to effect the vaporization of the ether by such
heat, the ether vapour so produced being then used to work an ether vapour
engine, substantially as described.
2. The combination of the cylinder jacket of an ether vapour engine, the jacket
of the ether vapour supply pipe of such engine, and of the jacket and evaporating
tubes of the ether vapour generator, with the discharge pipe or passages of a gas
motor engine through which the hot combustion gases escape, in such manner that
the said combustion gases, in being made to circulate through the cylinder jacket,
the ether supply pipe jacket, and the jacket and tubes of the ether vapour
generator, or through any one of them, is made to give off its heat to those parts
so as to prevent condensation of ether vapour and to effect the vaporization of
the ether substantially as described.
3. The combination of a gas motor engine, a motor engine worked by ether
vapour or other volatile fluid, and a generator of ether vapour or other volatile
fluid the said parts being arranged and operating substantially as herein described
with reference to the drawings for the purpose of utilising the waste heat of the
gas motor engine for producing ether vapour for working the ether vapour engine.
