    (54) INTERNAL COMBUSTION ENGINE
    one
    The invention relates to mechanical engineering, namely engine-building and, in particular, to structures of internal combustion engines by pre-chambers.
    Diesel cycle internal combustion engines are known that contain the cylinder block, its head and the pre-chamber formed by a cavity in a metal insert placed in the head, bounded from the end by the nozzle body and made of two coaxial parts, the first of which has a cylindrical shape with the bottom part the form of a truncated cone adjoining the second hour is amply cylindrical, connected to the gas outlet channel, the latter being inclined at an angle of 12СР relative to the longitudinal axis of the cylindrical hour predkg1Mery her; the volume of the first part of the pre-chamber is 85% of the total volume of the predgilers, and the volume of the second part is 15% 1.
    However, although these engines are high-speed, they differ in very uneven speed due to the non-optimal shape and size of the pre-chamber.
    The aim of the invention is to simplify the design of the cylinder head. .
    To achieve this goal, the longitudinal axis of the prechamber is inclined at an angle of 20 ± 5 ° to the longitudinal axis of the cylinder.
    In order to place the candlestick in the antechamber, the vent can be provided with a hole in the side wall in the area remote from the channel.
    FIG. 1 shows the engine, a section with the installation of the liner with the pre-chamber at an angle to the axis of the cylinder; 5 in FIG. 2 - the engine, a section with installation of an insert with the precamera in parallel with an axis of the cylinder.
    The diesel cycle internal combustion engine contains a block 1 of a cylinder 2 with a head 3 of block 1, in which prechamber 4 is located, formed by a cavity 5 placed in a metal liner 6. The cavity 5, from the end 7, limited by body 5 of nozzle 8, consists of two coaxial parts 9 and 10, the first of which (9) has a cylindrical shape, the lower part of which is made in the form of a truncated cone 11, and the second (10) also has a cylindrical shape.
    communicated with channel 12 for the exit of gases. Channel 12 is inclined relative to the longitudinal axis 13 of the cylindrical parts of the prechamber 4, i.e. . the longitudinal axis of the precamera, which is inclined at an angle of 20 + 5® to the longitudinal axis 14 of the cylinder 2-. The Ladder B may be provided with an aperture 15 in the side wall 1b in an area remote from the channel 12 for placing a spark plug in it. The volume of the first part 9 of the pre-chamber is 85% of the total volume of the pre-chamber, and the volume of the second part is 15%,
    When the engine is in operation, the prechamber 4 releases fuel through the nozzle 8. After its ignition, the combustion products go through channel 12 to the cylinder 2 of the engine.
