This invention relates to improvements in the cbnstruction, arrangement and in the mode of operating reciprocating engines of the type in which the pistons reciprocate 5 along lines parallel to the axis of the shaft of the engine, such engines being designated herein, for the sake of brevity, crankless engines.
fThJe object of the invention is to produce 10 an engine of that type which shall have greater flexibility and which shalladmit of more convenient and eflicient methods of control than existing internal combustlon or explosion engines. 0
By the expression greater flexibility: is meant that the engine is capable of operating at any given speed, with a greater range of turning moment and consequently of power, without limitations due to defectlve 1gnition or combustion of the fuel.
It is a well-known defect of existing internal combustion (and explosion engines, that the range of turning moment which they are capable of exerting at given speed s comparativel small. For this reason lt'IS usual to com ine with such engines a vanable transmission gear which enables the turning moment applied to the driven shaft to be increased or diminished independently of that exerted by the engine.
It is one of the aims of the present invention to dispense, either completely or partially, with such transmission gear. In particular, the improvements in construction and operation are intended to be applied to internal combustion and explosion engines of the crankless type for the propuls on of land vehicles, including railway locomot ves, with the object of conferring on such engines the characteristic of flexibilit which enables steam engines to be used or such purposes without the addition of change-speed mechanical gearing or other variable transmission apparatus. I r
The accompanying drawing is a longitudinal sectional view through a multi-cylinder engine to illustrate one of the cylinder units incorporating a practical example of the invention.
5 For the purpose 'of illustration the invention iss hown in application to a crankless engine of thekind described in the specification of United States Patent N 0. 1,409,057, Reissue No. 15,756. For the description of thev mechanism of this engine, and for definition of the terms hereinafter used in describing that mechanism, reference is directed to the above citedspecification.
' The engine is constructed with one or more internal combustion cylinders 1 which operate on one or other offthe. well-known internal combustion or explosion cycles, either four-stroke or two-stroke 'Where a plurality of cylinders are arranged about the main shaft the construction may accord with that described in the above cited patent. As in all such engines, the essential operations are that the working fluid. is compressed during the upward stroke of the piston 2 with a rise of pressure depending on the ratio of the clearance volume 3 to the volume swept by the piston. The fuel is either introduced before compression or is injected after compression and ignited either by the heat generated by the compression of theair or by electric spark or other suitable means. The
mately proportional to the volume of the compression space.
In internal combustion and explosion engines as usually constructed the volume of the compression space is fixed. Constructions are, however, already known, in which,
the compression volume is variable.- The;pre-. sent inventlon consists of means producing such variation in a crankless engine, and also includes .means for varying the air supply to the said compression space. I
The main shaft 4 of the engine on which is mounted the slant 5 is carried in journal bearings 6, 7 and its longitudinal position is determined by the thrust bearing 8. The engine piston 2, is rigidly connected through the yoke 9 to a piston 10, the two pistons thus reciprocating together as the slant revolves. The piston 10 reciprocating in the cylinder 11 serves to supply air for the combustion in the power cylinder through connecting passages or pipes not shown in the drawing.
Valves 11"? are provided in the'cylinder head 12 for admitting air into the cylinder 11 from the atmosphere and for controlling. delivery of air compressed in that cylinder to the power cylinder 1. These "alves may be either automatically or mechanically operated. A portion 13 of the cylinder wall at the end remote from the head 12 of the cylinder 11, is perforated but is constructed so as to be capable of being closed and rendered effective as a cylinder wall by the movable sleeve 14. In the drawing, the position of the sleeve 14 is such as to give the maximum degree of opening to the perforations,-and as the piston 10 overruns these perforations in its working stroke only the portion of the cylinder, between the cylinder head and the perforations nearest thereto is available for delivering air to the power cylinder 1. By moving the sleeve 14 towards the left, a
larger and larger portion of the cylinderbecomes so available, and a larger and larger quantity of air is compressed at each working stroke into the power cylinder 1.
As already stated,the pressure to which such air can be compressed is limited by practical consideration. In order that the power cylinder 1 mayreceive the larger quantities of air without exceeding the permissible pressure, means are provided for increasing the effective volume of the compression space when required. For this purpose the thrust hearing Sis mounted in a movable housing'15, which is made capable of being moved longitudinally with respect to the frame 16 of the engine, and to the cylinder 1 which is fixed to the said frame. For this purpose the housing may be furnished with a screw 17 which is provided with means, such as a gear wheel'18, for rotating it in the nut 19 attached to the engine frame. Rotation of the gearwheel 18, which may be effected by hand,
vor bygearing from the engine itself, or by "an independent motor, thus moves longitudinally the engine shaft, slant 5 and pistons2 and 10. If the motion is towards the right the compression space 3 in the cylinder 1 is increased, while the compression space 20 in the head of the cylinder 11 and the ex- 'tent to which the piston 10 overruns the perforated portion 13 of the cylinder 11 are both diminished. Thus simultaneously the cylinder 1 is adapted to receive more air, and
' the cylinder 11 to supply an increased quantity. The latter'eifect is enhanced if atthe same time the sleeve 14 is moved longitudinally to the left over the perforated portion 13 of the cylinder 11, and for this purpose the gear Wheel 18 may be arranged to engage with a gear wheel 21 mounted on a screw 22 engaging in nut 23 attached to the sleeve 14. Alternatively, the sleeve 14 may be actuated by means'independent of the means employed for moving the thrust hearing 8.
In addition to the variation of the quantity of air admitted to the power cylinder 1 by the means above described, the quantity of fuel supplied to the cylinder may also be varied, as by varying the stroke of the fuel pump, or by opening or closing a bypass valve on the fuel-supply pipe, or by other known means. Such mechanism controlling the fuel supply, may be automatically coupled to the mechanism for varying the air supply, so that the quantities of air and fuel increase or diminish together. .But, in order to give a Wider range of variation of power of the engine, the diminution of the fuel supply may be continued, after the air supply has been reduced'to the limit which the means of its control permits and down to the point at which the proportion of fuel to air is so low that efficient combustion no longer takes place. When more than one of the intake cylinders 11 are used, they may be arranged to deliver separately into corresponding power cylinders 1, or may deliver into a common reservoir from which each of the power cylinders is supplied in turn.
It is to be understood that in placeof the sleeve 14 operating in connection with the perforated cylinder wall 13, other means may be employed for varying the effective volume of the cylinder 11, and in certain cases such means may be omitted altogether if sufficient variation'of the quantity of combustion mi 1' is provided by the variation of the limits of the the stroke of the piston 10 consequent ou the movement of the thrust bearing 8. It is also to be understood that the thrust bearing 8, mnylw applied directly to the slant 5 instead of to a collar on the shaft 4 and that the slant 5 may be arranged to slide longitudinally on the shaft instead of being rigidly mounted thereon, and that various means other than a screw, may be employed for moving the slant longitudinally. Thus it may be moved by 'the plunger of a small hydraulic press sup plied with oil under pressure from a pump driven by the engine. The movement of the thrust bearing whether by a screw or other means may be controlled directly by the driver or may be effectedautomatically according to the speed or load of the engine through a centrifugal "governor or like contrivance.
