    The invention relates to mechanical engineering, in particular to internal combustion engines, and can be used in engines with a combustion chamber located in a piston.
    A known internal combustion engine with direct injection, air compression and self-ignition, comprising a piston in which a combustion chamber is located, made in the form of a body of rotation, in which rotary motion is attached to the incoming air for combustion, installed in the head opening of the unit fitted with a nozzle holder, through which fuel is injected into the combustion chamber
    In a known engine, the required power is provided with satisfactory fuel efficiency. However, a known engine is not sufficiently reliable due to the high rigidity of the combustion process.
    Also known is an internal combustion engine with direct injection, air compression and self-ignition, comprising a piston in which a combustion chamber is disposed in the shape of a rotation body in which a rotary motion is attached to the incoming combustion air around the longitudinal axis of the combustion chamber mounted in the head hole cylinder block displaced relative to the center of the combustion chamber and fitted with a nozzle holder through which fuel is injected into the combustion chamber in one stream into the flow Rotating air and forms a fuel film on the wall of the combustion chamber, the injector injection hole being located in the combustion chamber below the piston bottom when it is in the top dead center, and the injector neck is installed in the opening of the cylinder block with a gap of 2J.
    Known engine has sufficient reliability.
    A disadvantage of the known engine is the increased toxicity of the exhaust gases due to the unsatisfactory combustion of the fuel.
    The aim of the invention is to reduce the toxicity of exhaust gases.
    To achieve a permanent goal in an internal injection engine with direct injection, compression
    air and self-ignition containing a piston in which the combustion chamber is located, made in the form of a body of rotation, in which the inlet air for combustion of fuel is given a rotational movement around the longitudinal axis of the combustion chamber mounted in the cylinder head bore offset relative to the center of the combustion chamber and a nozzle fitted with a holder through which fuel is injected into the combustion chamber with one stream in the direction of the rotating air and forms a fuel film on the wall of the combustion chamber the injection nozzle opening is located in the combustion chamber below the piston bottom when it is located at the top dead center, and the nozzle neck is installed in the hole of the cylinder block with a gap, the hole of the cylinder block of the cylinder block is provided with a sleeve with a longitudinal slit and an open end, located 5 times wide -she injection holes.
    The open end may be located 0.52 mm below the injection port.
    The width of the slotted slot in the cold state during installation can be 0.5–2 mm.
    The outer diameter of the liner in the free state can be made 1-1.3 times the diameter of the hole in the cylinder head,
    The sleeve on the side of the nozzle holder can be provided with a collar.
    Figure 1 shows an internal combustion engine with direct injection, air compression and self-ignition, a general view; in Fig.2 a sleeve and a nozzle, a cross-section (section A-A in Fig.1); in FIG. 3, an engine indicating the direction of gas movement after passing the top dead center and fuel, a general view5 of FIG. 4 is a diagram of the movement of the piston during the injection process with an image of the depth of the injection hole in the combustion chamber.
    The internal combustion engine contains a piston I in which the combustion chamber 2 is located, made in the form of a body of rotation. The combustion chamber 2 has, in the direction of the cylinder head 3 of the cylinders 3, a narrowed neck 4 in which the connecting channel 5 is made. In the opening 6 of the cylinder head.

    on the nozzle 7, provided with a holder 8. The nozzle 7 is installed with an offset from the center 9 of the combustion chamber 2 in the connecting channel 5, the injection port 10 of the nozzle 7 is located in the combustion chamber 2 below the bottom II of the piston 1 at the top dead center
    (t).
    Hole 6 is provided with a sleeve 12 with a longitudinal guide 13 and, with the open end 14 located below, the injection holes 6 are 0.5-2 mm, more preferably 1.0 mm.
    The outer diameter of the sleeve 12 in the free state is 1-1.3 times (mostly 1.1 times) larger than the diameter of the hole 6 in the cylinder head 3.
    The width of the slotted sleeve in the cold state during installation is 0.5-2 mm.
    Between the sleeve 12 and the neck 15 of the nozzle 7 is made a gap 16, and from the side of the holder 8, the sleeve is equipped with a flange 17,
    During the operation, the internal combustion engine injects combustion air with a rotary motion around the longitudinal axis 18 of the combustion chamber 2. The fuel is injected through the nozzle 7 into the combustion chamber with one jet 19 in the direction of the rotating air 20 and forms a fuel film on the wall 21 of the combustion chamber (not shown).
    Around the injected fuel line B-19 there is in ialichii fuel mist 22, consisting of not having
    514
    energy droplets-fuel. After the passage into MT, the radial movement of gas 23 begins, and the immersion of the nozzle injection hole into the combustion chamber during the injection process prevents fuel from entering between the piston head and the cylinder head, i.e. in relatively cold places.
    The immersion depth of the injection port, measured in the vertical direction, is equal to the piston bottom at the end of the fuel phase at the nominal speed and full load from the bottom position in MT. Fuel mixed by rotating air is deposited in the base on the lower, protruding front wall of the liner.
    Since this area of the liner is very hot, there is a rapid evaporation of the fuel. Sleeve protects
    the overheating nozzle, which prevents the injection hole from coking and the nozzle warping. A longitudinal slot ensures free stress, good contact of the sleeve.
    with cooled cylinder head.
    Thus, by making the cylinder head bore, provided with a sleeve with a longitudinal slit and an open end located below the injection bore, it is possible to reduce the toxicity of exhaust gases.
