UNITED STATES PATENT OFFICE.
COMBUSTION-ENGINE- Specification of Letterl Patent.
Patented Nov. 16, 1909.
Application filed Kay 28, 1908.. Serial No. 435,600.
To all whom it may'concem:
Be it known that I, CASIMIR STANISLAS lmsrmn, a subject of His Majesty the Emperor of Austria-Hungary, residlng at 97 Fleet street, London, E. (1, England, civil engineer, have invented a new and useful Internal-Combustion Engine, of which the following is a specification.
My invention relates to internal combustion engines of the type in which combustion takes place at constant pressure and in which the air for combustion is 00111- pressed in a separate air compressor outside of the working motor or motors, and has for its object the recovery of a portion of the waste or lost heat of such an engine, 2'. e. the heat of compression, the heat passing to the cooling fluid in the jackets of the cylinders or motors, and the heat of the exhaust gases.
This invention contemplates the realization of this object by the production of intense cold with liquefaction of the air prior to combustion in the engine cylinders, thereby making possible the heat transference above referred to.
Under the invention either reciprocating compressors and motors, or turbine compressors and motors, or a combination of bothmay be used, the operation thereof being as follows Air is drawn in and compressed in an air compressor in one or more stages and cooled to a temperature about or below that of the atmosphere, and is then used as the working fluid in a compressed air motor which is. insulated to prevent the flow of heat into the expanding air, and this air in expanding cools itself to a temperature approaching that of the liquefaction point of air.
The pressure to which the air is compressed, the temperature to which it is cooled before entering the compressed air motor and the volume to which it expands in the compressed air motor are so. proportioned that this result is obtained. The cooled air then passes into a temperature exchan er, wherein the whole or a portion of it isurther cooled and liquefied and the liquid air is then pumped into a receiver or system of piping at a pressure rather higher than the initial pressure in the internal combustion motors. The liquid air is then volatilized at this pressure and heated by passing it through a series of temperature exchangers, wherein it receives heat from the compressed air, the compressor jackets, the motor 'ackets' and the exhaust ases, or some 0 them. Into the air thus eated is injected fuel which may be in the form of compressed gas, or a spray of liquid, or of coal dust, combustion taking place spontaneously, or if necessary with the assistance of an i iting mechanism of any suitable known rind, such combustion taking place either in an external chamber or inside the motor or motors themselves. The hot gases then operate in the Working motors in the usual manner and exhaust to the atmosphere after parting with a portion of their heat to the compressed air.
In the accompanying drawings Figure 1 is an elevation showing diagrammatically the arrangement of a plston engine according to this invention. Fig. 2 is a similar view representing a turbine engine of this kind.
Referring to the drawings, air is drawn at Ainto the compressor j by which it is compressed, and is cooled by the volatilized liquid air in a temperature exchanger k. The compressed and cooled air is stored up in a receiver Z, from which it passes into any suitable and well known expansion cylinder m, wherein it expands to about the point of liquefaction of air and, in actingon the piston m, produces effective work. On leaving the expansion cylinder m, the air passes to a temperature exchanger 11, which may be of any appropriate or known type, and wherein the whole or aportion of the air is liquefied, and through which it is forced by means of a pump 11.. It is then pumped into the temperature exchanger it, into the jacket of the compressor j, and into the cooling jackets of the engine cylinder or cylinders 0, 7), wherein it takes up heat given off by the walls of said cylinders. From the engine jackets the air produced by the volatilize.- tion of the liquid air and now heated enters the chamber t, wherein take place, at the same time as the transference to the air of heat from the exhaust gases of the engine, the mixing of the air with the fuel, and also the combustion of the mixture thus obtained, in the case in which the combustion takes place outside of the cylinder. From such chamber t the gases of combustion pass through a pipe u to the engine cylinders 0, p, {the exhaust of which is connected by a pipe 'v, with the said chamber t, from which the exhaust products escape at E after giving up a portion of their heat to the compresse alr.
The engine represented in Fig. 2 is similar to that shown in Fi 1 and operates m hke manner, with the ifierence that the cylinders y, m, 0, 1p and the pistons working therein are rep aced by turbines 7", m", 0* which constitute respectively the compressing turbine, the expansion turbine, and the motive-power turbine.
While I have described in the foregoing s ecification the construction of parts essential to the operation of this invention, I am aware that numerous changes of construction and o eration may be made without departing om the spirit and scope of the invention, and I therefore do not wish to understood as limiting myself by the pos1- tive terms employed in connectlon with the description, excepting such as the state of the art may require.
