    Ie) eestsn internal combustion engine
    with a chi; compression pattern containing a cylinder with an ijopunie, a slumped combustion chamber, a body in the form of a rotational body with a constricted bypass hole, with respect to the axis of which the inlet D turns. the edge of the bypass nozzle for fuel injection with one jet to the wall of the combustion chamber in its lower quarter in the Lenin air flow, and the wall of the secondary bypass hole is variable height (1 along the perimeter and parallel axis of the chamber with mountains and distance to spray fuel from the camera axis
    is 0.35-0.7 diameter: the chamber burns 1,
    One) during the operation of a known engine in the range of the rotational speed is too strong a swirl of the air flow negatively affects the combustion, because it deflects a stream of nocTynajoniero fuel to the chamber wall, which in this case has a small kinetic energy, which increases the toxicity of the exhausted gases,
    The purpose of the invention is to reduce the toxicity of exhaust gases.
    This goal is achieved by the fact that in the engine of an internal compression / trennial combustion engine containing a cylinder with a piston, a sabzh khyeroy Commander, made in the body of the rotary body with an O11M 1M bypass OTBcpcnieM, with respect to the axis of which the receiver air cylinder
    and a shinsdra head with an eccentric eccentrically installed near it by the nozzle orifice for injecting a lump with one jet onto the wall of the combustion chamber in its lower quarter in the direction of short air, and the wall of the narrowed bypass orifice is made of a variable height along the perimeter and parallel to the axis of the combustion chamber, and The spraying point of the fuel from the chamber axis is 0.35 - OJ of the diameter of the combustion chamber, the narrowed bypass hole is oval-shaped, the larger diameter is the oval of the bypass hole From the periphery of this hole through the axis of the combustion chamber in the direction to the fuel point, and the geometric direction of the fuel spout, projecting Bainipe to the plane perpendicular to the axis of the combustion chamber, forms a straight line passing through the fuel split point and the chamber axis, 10 50 °, and with a plane, perpendicular to the axis of the 1samer, forms an angle of 20-60 °.
    The diameter of the overflow hole oval is 1.05-1.25.
    The right passing through the spray point of the fuel and the axis of the chamber is, with a large oval diameter, the overflow orifice within ± 20.
    The oval bypass hole is made in the form of an ellipse or an elongated hole, formed by two semi-circles and an intermediate intermediate part.
    The wall of the bypass hole is made of maximum height in the area of large-diameter and minimum - in the area of smaller diameter.
    The minimum wall height of the nepenycKicoro hole is 5-10%, and its maximum height is 15-20% of the diameter of the combustion chamber. FIG. 1 shows the proposed engine; in fig. 2 shows section A-A in FIG. one; in fig. 3. - BB incision on phage. 2; in fig. 4 - scan wall of the bypass hole. The proposed engine comprises a cylinder (not shown) with a piston 1 equipped with a combustion chamber 2 filled in the form of a rotational body, for example, a spherical shape with a diameter D, with a narrowed bypass hole 3, and a cylinder head 4 with an eccentric edge installed in it 3 nozzle 5 for fuel injection. Chamber 2 of combustion through the hole 3 is connected to the cavity b of the cylinder. Hole 7 can be made in hole 3 under nozzle 5. Hole 3 is oval in shape, which is an ellipse or an elongated hole formed by semicircles and an intermediate part, with a larger diameter from the oval of hole 3 extending from its periphery through axis 8 the combustion chamber 2 in the direction to the fuel atomizing point 9, and the ratio of the diameters dj / J of the oval is 1.05-1.25. The wall of the hole 3 is made of a variable height along the perimeter and parallel to the axis 8 of the combustion chamber 2, and the wall reaches the maximum height (15-20% of the diameter D of the combustion chamber 2 or in the region of larger diameter d and the minimum height (5-10% of diameter D chambers 2 combustion 1) - in the region of smaller diameter Ji. The distance E of the point 9 of fuel spraying from axis 8 is 0.35-0.7 of diameter D j The geometric direction of the jet 10 of fuel, projected onto a plane perpendicular to the base 8, forms with direct 11 passing through point 9, spraying and axis 8, angle V, pa 10-50 °, and with a plane perpendicular to the axis 8, forms an angle L of 20-60 °. Moreover, the straight line 11 is with a larger diameter d and the flow is within ± 20 ° and the point 9 of the spray is in the region 12. The engine operates as follows: When Porsch 1 moves to the bottom dead center during the suction stroke, the air entering rotates around the axis 8 of the combustion chamber 2. When the piston 1 moves to the top dead center during compression, air flows into the combustion chamber 2. vortex crushing poth. At the end of the compression, the nozzle 5 injects the fuel in one stream against the wall of the combustion chamber 2 into the first quarter of the combustion chamber in the direction of air rotation. At the same time, the axisymmetric rotation of the air, which reaches its maximum speed at the upper dead point of the piston 1, particularly favorably affects the e-fuel atomized fuel. And since the crushing flow is also connected to the rotational motion, an intensive turbulence is created in the combustion chamber 2, which results in a quickly occurring high-quality preparation of the combustible mixture and significantly more efficient combustion process | . Thus, the implementation of the invention allows to reduce the toxicity of exhaust gases of the engine of internal combustion with compression ignition.
