    FIELD OF THE INVENTION The invention relates to the field of engine-building and makes it possible to increase reliability. The main combustion chamber and the pre-chamber of the internal combustion engine are connected by a tangential bypass channel, the central axis of which lies in the middle plane. In the same zone there passes a stream of fuel from a nozzle introduced through a glow plug wall. The latter is made in the form of a protruding element near the mid-plane, the heated tip of which, in a normal position, enters the marginal zone of the fuel jet. In the pre-chamber, in the side zone of the fuel jet, there are two glow plugs on both sides of the middle plane and are inclined to it at different angles. This makes it possible, when deflecting a jet of fuel, to always have one of the glow plugs in the marginal zone. 4 hp f-ly, 5 ill. (Y) from "05 About SP 4 CM

    This invention relates to mechanical engineering, in particular to internal combustion engines.
    The aim of the invention is to increase reliability.
    FIG. 1 shows the engine being sold; Fig. 2 is a section of the prechamber with the location of a glow plug (first and second variants); in fig. 3 - the same, with glow plugs located to the side of the fuel stream (the third option); Fig. 4 is the same, with two glow plugs entering the edge zone of the fuel jet with inclination to one another (the fourth option) in Fig. 5 is the same, with two candles being offset one from another and inclined to each other incandescence (fifth variant X20 ° of the middle plane 8, and
    The engine contains the main combustion chamber 1 formed by the head 2 of the cylinder 3 and the bottom 4 of the vessel 5 placed in the cylinder, and the vortex prechamber 6. The pre-chamber 6 is made in the head 2 and connected to the main chamber 1 by means of a tangential bypass channel 7 entering under the blunt an angle in the bottom 4 of the piston 5, the central axis of which is in the middle plane 8. In addition, valves 9 are installed in the head 2 for gas exchange of the main chamber 1 "
    Approximately tangentially, the receiving opening 10 for mounting the fuel injection nozzle 11 in the form of a cone-like expanding fuel jet 12, which runs in the zone of the middle plane 8 through the center of the precalvan, retains the direction of rotation of the air entering through the inlet 13 of the channel 7, and is located at waste side of the whirlwind 14.

    In the second variant, the candlestick 15 (fig. 2) means a candle 15, the axis of the cat is not extended to the middle aperture 16, and the impostor 16 enters the regional pouring jet 12. At the same time, it is also located outside of the turn 13 and as a result of it comes the cold Cool The advantage of the second var compared with the first one is the tip 16 and, with a large jet, remains in its zone,
    According to the third variant, the prechamber 6 is provided with two 15, the axes of which the passage 16 enters the jet 12 in its diameter perpendicular to the plane 8. At this lump of the jet deflecting to the left of one or the other candle, the blob always has access temperature fuel jet. Both candles are outside the projection of the hole 13
    In accordance with the fourth volume (Fig. 4), both candles 15 are one to the other and corresponding to the middle plane 8, followed by their tips 16 are large in the radial direction 12. Moreover, with a small jet 12 in the direction of the middle 8, the tips 16 are light in the regional zone of st
    According to this option (fig. 5), candles 15 are arranged in such a way that their tips enter the marginal zone one relative to another.

    A glow plug 15 is screwed into the head 2 in the form of an element protruding near the middle plane 8, the heated tip 16 of which, in the normal position, enters the edge zone of the jet 12 in the center of the intersection of the planes,
    In the first embodiment, the candle 15 is connected to the fuel jet 12 in such a way that the lateral surface of its tip 16 enters the marginal zone of the jet 12j and its axis runs parallel to the midplane 8 and outside the projection of the inlet 13.

    In the second embodiment (Fig. 2), a dash-dotted line indicates a candle 15, the axis of which is obliquely. The middle air gap 8 is not located, and the tip 16 enters the marginal zone of the fuel jet 12. At the same time, the candle 15 is also located outside the projection of the hole 13 and, as a result, is not blown by the incoming cold air, which could cool it. The advantage of the second variant as compared with the first one is that the tip 16 and in case of large deviations of the jet remains in its marginal zone,
    According to the third variant (FIG. 3), the prechamber 6 is provided with two candles 15, the axes of which are parallel — the tips 16 enter the jet 12 within its diameter perpendicular to the median plane 8. In this case, the deflections of the jet are compensated left or right to one or another candle, due to which the temperature is always high enough to ignite the fuel jet. Both candles 15 are outside the projection of the hole 13.
    In accordance with the fourth variant (Fig. 4), both candles 15 are inclined one to the other and, accordingly, to the middle plane 8, as a result of which their tips 16 more largely enter the stream 12 in the radial direction. Moreover, with a small deflection of the jet 12 the direction of the middle plane 8, the tips 16 of the candles 15 still remain in the marginal zone of the jet 12.
    According to the fifth embodiment (Fig. 5), the candles 15 are arranged in such a way that their tips 16 enter the edge zone of the jet 12 and are displaced one with another in the direction of the middle plane 8, as a result of which the tip of the second candle enters the edge zone of the jet 12 approximately diametrically opposite to the first tip. In this case, in the case of deviation of the jet 12 as in the direction of the middle plane 8 and perpendicular to it. One of the candles 15 is always in contact with the edge zone of the jet 12.
