    1467394 Charging IC engines W FRANKE 18 Feb 1974 [19 Feb 1973] 7291/74 Heading F1B [Also in Division F2] A two-stroke I.C. engine comprises a cylinder 1 divided by a partition 13 into a power chamber 10, 30 and a compression chamber 33, 36, which are respectively divided into working chamber 10 and auxiliary chamber 30 and into a first subsidiary compression chamber 33 and a second subsidiary compression chamber 36. A power piston 12 and compression piston 24 are movable in unison and connected to a crank-shaft 2 and input and exhaust ports 32, 16 communicate with the working chamber 10 when the pistons are at BDC and with the auxiliary chamber when the pistons are at TDC. A valve controlled air intake 19 communicates with the first subsidiary compression chamber 33 and a transfer duct 31, 37 connects via a valve 48 the chamber 33 to the input port 32 and to the chamber 36. A second intake 25 is connected to the chamber 36 via a second valve 27. Mixture drawn in through the second intake 25 is compressed in chamber 36 then conveyed via duct 31, 37 to working chamber 10 as the pistons descend towards BDC. Air drawn in through first intake 19 is compressed and admitted to duct 31 when the pistons are near TDC opening the port 46 and closing duct 37, the air scavenging the exhaust duct 15. If an intake port 56 for an admission of mixture to the working chamber 10, air instead of mixture may be drawn in through the second intake 25. In the Fig. 6 embodiment, on the upward stroke of the pistons, air is expelled from chamber 33 via opening 46, duct 31 and chamber 30 to the exhaust duct 17, mixture in chamber 10 is compressed; air is drawn into chamber 30 through inlet 54 and mixture is drawn into chamber 50 via one-way valve 27. During the working stroke of the pistons air is drawn into chamber 33 via one-way valve 21 and when the mixture in chamber 50 is sufficiently compressed, two way valve 48 moves from the position shown to allow the mixture to flow via ducts 37, 31 to the working chamber 10. If a further inlet 56 as in Fig. 5 for mixture is provided, air instead of mixture may be supplied via valve 27.

    The invention relates to mechanical engineering, namely to engine building, in particular, to two-stroke internal combustion engines.
    Known are two-stroke internal combustion engines containing at least one pair of cylinders, of which the first, with a smaller cross section, is equipped with inlet bodies 10 and a spark plug, and the second with adjustable exhaust bodies, pistons kinematically connected to each other, located in the cylinders and separating a cylinder on the over-piston and under-piston cavities, and a connecting channel connected to the cylinders adjacent to the piston bottoms when they are at bottom dead center in the over-piston cavities. In such engines, the fuel-air mixture is introduced into the cylinder with a smaller cross-section, where it is compressed and ignited using a spark plug. When approaching the bottom dead center, the piston 25 of this cylinder opens its connecting edge with its upper edge, and the exhaust gases flow into the second cylinder with a large cross-section, where they further expand and move the piston located in this cylinder. An additional expansion of the exhaust gases in the second cylinder allows the amount of useful heat L11 to be increased.
    . However, in these engines no measures are taken to increase the completeness of combustion of the fuel-air mixture.
    The purpose of the invention is to increase the completeness of combustion.
    This goal is achieved by the fact that the second cylinder is equipped with an additional spark plug, the under-piston cavities of the cylinders are interconnected using an additional channel and additional windows made in the under-piston cavities, and the first cylinder is made with a channel for transferring charge from the under-piston cavity to the over-piston cavity.
    In addition, the cylinders are placed in pairs in three groups located in the same plane, and their pistons are kinematically connected to each other by means of; three rods displaced relative to each other, and the pistons are located on each rod on both sides, one of the pistons is made with a smaller cross section.
    In FIG. 1 shows an engine in a rotary design with one cylinder-piston unit, a longitudinal section; 'in FIG. 2 is a view A in FIG. 1, in FIG. 3 section BB in FIG. 1; in FIG. 4 - a rotary engine used as a gyroscope for stabilization, cross section; in FIG. 5, the rotor of the engine with the smaller and larger 'pistons 57 and 58, which are connected to the inlet and outlet nozzles by means of slip rings similar to those shown in FIG. 1 slip rings 55 and 56.
    c. The essence of the invention most fully covers the engine depicted in FIG. 5. Pistons 57-62 are kinematically connected with each other by means of rods 63, 64 and 65 in such a way that there are pistons with smaller cross-sections on each rod with one hundred and roons, a cross section; in FIG. 6 is a variant of the design of the valve, which can be installed on the described engine;
    in FIG. 7 - another version of the plate-15 chaty valve.
    In the engine (Fig. 1), the stator 1 mounted on the support 2 forms a cavity 3 bounded by a round wall '4 .. On the support 5 of the stator 1 there is a driven shaft 6 provided with a flange 7, on the protrusion 8 of which the left wall is fixed rotor 9.
    The right wall of the rotor 9 is mounted by means of a bearing 10 on the protrusion 25 pe 11 located on the stator 1.
    On the opposite side of the driven shaft 6 in the wall of the stator 1 there is a root neck 12 of the cranks 13 and 14 connected by rods ..η
    15-18 pistons 19-22. Inside the rotor are cylinders 23-26 offset by 90 ° relative to each other.
    Cylinders divided by partitions 1
    27-3 (5 (see. Fig. 3), mounted on rods and partitions 31-34, mounted on the walls of the cylinders.
    In the caps of the cylinders 35-38, ignition devices 39-42 are placed, which, by means of their sliding contacts, communicate with the contact strip 40 43 located on the inside of the round wall'4. The outlet pipe 44 (see Fig. 2), equipped with an additional spark plug 45, is connected to the channel 46 with valves 47. 45 The inlet pipe 48, equipped with a valve 49, is in communication with the channel 46 and connected to the cavity 50 formed by the baffles. 27 and 31. The second inlet 51 includes a valve 52 and is connected to the cavities formed by the cylinder cover 35 and the piston 20, the baffle: 31 and the piston 20 through the channels 53 and 54, and the outlet 44 and the inlet 48 and 51 of the pipe during rotation • the torus 9 is connected to the corresponding • channels by means of slip rings 55 and 56. The engine variant (Fig. 4) contains the same elements as the motor in Fig. 1-3 except for the partitions fixed to the rods, because of which there are no cavities between the partitions and, therefore, the inlet pipe with valves in these cavities. The inlet of the fuel-air mixture and the exhaust gas are discharged through an ok-65 cross section, with the pistons of various cross sections lying nearby. Pistons are placed in the cylinders and divide them into a supra-piston cavity 66-70 (one supra-piston cavity in Fig. 5 is not indicated) and a sub-piston cavity 71-76. All cylinders are equipped with ignition devices 77-81 (one ignition device in Fig. 5 is not indicated). The connecting channels 82, 83 and 84 are connected to the cylinders adjacent to the piston bottoms when they are located at the bottom dead center in the over-piston cavities, and the under-piston cavities are interconnected by additional channels 85, 86 and 87, and cylinders with smaller cross sections are made with overflow channels 88, 89 and 90 in the over-piston ones.
    The under-piston cavities of the cylinders with large cross sections are provided with inlet bodies 91 (the rest are not shown in Fig. 5), and the over-piston cavities are equipped with outlet 92 and 93 (the remaining are not indicated), and the under-piston cavities of the cylinders with smaller cross sections are also equipped with inlet bodies 94 and 95 located respectively in the sub-piston and supra-piston cavities.
    When the piston 58 moves at the top dead center, the freshly absorbed mixture enters the piston cavity 73, where it is liquefied by the reverse movement of the piston 58 and is transferred via the channel 88 to the over-piston cavity 68 for purging and filling. The exhaust gases generated as a result of ignition with the aid of a candle 79 of the previous charge, rush into the super-piston cavity 67 of the cylinder with a large cross-section, where they are additionally compressed and burned using the spark plug 78. The under-piston cavity of the cylinders with smaller and larger cross-sections is communicated via channel 85 and a fresh charge when the pistons move to the top dead center is fed into the piston cavity 72 ^ of the cylinder with a large cross section.
    The use of the proposed engine allows to increase the completeness of combustion and, therefore, to reduce the toxicity of exhaust gases.
