On to figure 1 a cut in a plane containing an axis crankshaft (CS) and axis of two coaxial cylinders is represented Engine -; on to figure 2 a cut on A-A across an axis CS is represented Engine -; on to figure 3 a design version of the bearing, fragment of a cut on A-A is represented; on to figure 4 a plane of sliding of the bearing - cut on B-B is represented; on to figure 5 variant of installation of vents - cut on C-C is represented.
Offered two-stroke Engine contains: installed in crank case 1 CS 2, have Cheeks-Counterbalance 3 and crank 4, mutually On one axis located on crank case cylinders 5, 6, 7, 8, pistons of cylinders 9, 10, 11, 12, is rigid mutually On one axis(axes) connected among themselves by rods 13 and 14 with coulisses 15 and 16, rigidly mounted in a central parts of rods, the horizontal through slot of a coulisse is executed across an axis of a rod, breaking off it and symmetric disperse in the parties, through a slot of coulisses passes crank, on crank are installed bearings 17, 18, external diameter of which there is less height of a slot of a coulisse. On CS the disk 19 with Program by grooves at end faces is installed, with which kinematics connect rods of vents. The cylinder 7 is equipped by combustion chambers (CC) 20, 21 above and under the piston with fuel - giving by injectors 22, 23, fuel piston of two indirect operations 24 and installed in the channel, leaving from an average level of a wall of the cylinder by a vent 25 on rods 26, under a vent the channel from a disk drive approaches, and above a vent there is the exhaust hole (cylinder 5 is equipped similarly to the cylinder 7). The cylinder 8 is equipped by two inlet vents 27, 28 on a rod 29, they are each in the channel, leaving from extreme sites of walls of the cylinder, and two irrevocable vents 30, 31, fixed on shaking support, installed in butt-end walls of the cylinder and being by-pass of the cylinder in a reservoir 32 (the cylinder 6 is equipped similarly to the cylinder 8). As variant: the bearing (s) crank is executed with planes of sliding, interacting to an a surface of an of a slot of an of a coulisse and equipped By recesses 33 on an axis of sliding for grab of oil. As variant: in the cylinder, equipped with two combustion chambers, in channels, leaving from a wall of the cylinder on an average level, two coaxial vents 34, 35, fixed on rods are installed which are connected to the T-shaped thruster 36, Kinematics connected with the disk drive, under the first vent the channel from a disk drive approaches, and above the second vent there is the exhaust hole.
Engine works as follows: When in the cylinder 7 pistons 9 is in To upper Dead Stop (UDS), Under piston volume of the cylinder fills in compressed air, arriving from a reservoir 32 through channels under vent 34, and in CC 20, filled with compressed air, happens an injection of fuel by an injector 22, the fuel is ignited and makes action, moving the piston downwards, in the meantime the piston 10 in the cylinder 8, connected with the piston by 7 rods 13, being go down, makes compression of air in underpiston volume for the consequent receipt it in the tank of a reservoir through the channel under an irrevocable vent 31, and in overpiston volume takes place suction of air through the channel under a vent 27, thus the coulisse 15 transmits an effort on installed to its slot crank 4 through the bearing 17, forcing it to move on a slot across an axis of a rod and on a circle of the rotation on CS 2. When the piston 9, being go down, passes at a level of the channel from the cylinder to vents 34, 35, vents are go down under effect of change of radial distance of a program groove on the disk 19 in a point of kinematic connection with the T-shaped thruster 36, owing to that the exhaust channel above a vent 35 is opened, and further for want of movement of the piston up to lower dead stop (LDS) there is the exhaust from upper volume of the cylinder, and in LDS of a vent return in a upper position, closing the exhaust channel and opening the channel from the tank of a reervoir, thus in underpiston CC 21, filled in by compressed air, there is the injection of fuel by an injector 23, radial distance Program of the track of the disk, Kinematic connected with a valving rod 29 is at the same time changed in a point of a contact which, being go down with vents, overlaps the channel under a vent 27, opens the channel over a vent 28 and closes irrevocable vent 31, overlapping channel to tank of a reservoir. Further, for want of movement of pistons up, the processes, occurring in overpiston and underpiston volumes of both cylinders, change places. (the Cylinder 5 works similarly to the cylinder 7, and cylinder 6 is similar to the cylinder 8, whereas the coulisse 16 on a rod 14 similarly transmits a load on same crank 4, with offset of a phase on CS on 90 degrees).
Construction two-stroke Engine on the basis of the piston of double-side operation in one cylinder (thereby form two independent CC) and piston of double-side operation of greater diameter in the coaxial cylinder (there are two independent cameras of the compressor) allows to increase power of the engine, as all operation load evenly acts on one crank CS, and also because of that in volume each such CC we can burn of fuel more, than in CC of the cylinder of equal volume, but without a piston supercharger, thus achievement of high frequency of revolutions Engine at the expense of large volume of air, under high pressure delivered by the compressor is possible.
Use coulisse of the device for transformation of reciprocating movement of pistons to rotary movement CS allows to increase reliability of the engine at the expense of simplification of a construction, as four independent cameras are served, in effect, by the uniform block - piston (two pistons on a rod with a coulisse). As the rigid fixing of a coulisse on an interrupted rod provides to the block - piston maximum strength and stability, as its base it is possible to consider the relation of diameter of a rod to distance between points of its contact with walls of holes in covers of cylinders. Thus decrease of dimensions of the engine is supplied.
Is the most preferable four cylinder variant of this engine, as the load on crank acts on two axis from four CC the most evenly, thus such engine without superfluous complicating is balanced Counterbalance on CS, as, for example, in the scheme "Star".
Manufacturing bearings crank with sliding planes, equipped oil receiving by recesses, will increase resource of working surfaces of a slot of a coulisse.
Use without spring of the drive of vents in the above described subroutine linkage will allow given Engine to reach high operational frequency, and consequently, and specific power.
The equipment of the cylinder, have two combustion chambers, two vents, and under the first vent approaches the channel from a disk drive, and above the second vent there is the exhaust hole, allows to receive period of a pressurization of the cylinder at the moment of movement of vents, not complicating Kinematic of the scheme, that will increase profitability Engines.
The given subroutine linkage of the engine allows to improve efficiency two-stroke Engines, as the relation of total square of friction to made power decreases, as the main seals are installed on the piston, servicing two CC, and on Forcing the piston of double-side operation them is installed on a minimum. Besides diameter Interacting by friction of seals of the working piston there is less diameter Interacting by friction of seals Forcing of the piston, which determines working volume of air. Thus the pistons not interact with walls, as basic and directing functions are executed by a rod. And main, in because of that we have a large difference in volumes of the working cylinder and compressor and possibility to create large pressure of air in a reservoir, it is necessary after an exhaust to overlap the exhaust channel at the moment of opening the inlet channel, that to exclude loss of air. And the above described difference of volumes will allow to lower concentration of spent gases in CC, that maximum combustion of fuel will ensure. All this and will allow to reach stated increase efficiency.
