    A combustion process and apparatus for a spark ignited air compressing internal combustion engine with direct injection of the major portion of the fuel onto the wall of the combustion chamber provided in the piston in the form of a body of revolution, according to which a rotary motion is imparted upon the inflowing air in such a way that the fuel is gradually released from the combustion chamber wall and mixed with the air in the form of vapors. The injection nozzle is positioned in the cylinder head near the combustion chamber throat while the ignition device extends into the combustion chamber at the top dead center position of the piston. The fuel is injected onto the combustion chamber wall by means of a jet from which individual small fuel particles are detached which are immediately mixed with the air on being emitted from the injection nozzle opening. The small amount of combustible mixture formed by the fuel particles detached from the fuel jet and not yet conveyed by the centrifugal forces onto the wall is toward the end of the injection phase ignited close to the injection nozzle opening by the ignition device. The thus initiated combustion propagates in the direction of the revolving air across to the fuel film existing on the wall of the combustion chamber in the piston. Subsequently the main combustion takes place in conformity with the progress of the mixture of the fuel vapors generated in the wall region with the air circulating in the combustion chamber.

    (54) INTERNAL COMBUSTION SWITCHER
    one
    The invention relates to the field of mashing, namely, to internal combustion engines.
    Internal combustion engines are known that contain at least one 5 cylinder with a piston placed in it, a cylinder head with a nozzle installed in it for injecting a liquid jet in the form of a jet into the wall of the combustion chamber which is shaped like a body of rotation, and zazh1p: an ani fuel placed in the combustion chamber at the position of the piston in the top dead center, the nozzle being inclined to the longitudinal axis of the combustion chamber and the central angle formed between the plane perpendicular to Aulnay-axis and a line connecting the injector nozzle to the point of fuel jet hitting the combustion chamber wall 20 is 145-160. In such engines, fuel is injected onto the wall of the combustion chamber located in the piston. Due to the small kinetic energy of the jet and the rotation of the
    In the air in the combustion chamber, the fuel spreads in the form of a thin film on the wall of the combustion chamber, from which it evaporates. A device for igniting the fuel located near the specified wall contributes to the ignition of the vaporized and mixed with the air fuel. As a result, the ignition moment is adjustable and is set in accordance with the engine operating parameters l.
    However, in the known engines, all possibilities are not used to improve the flammability of the fuel, especially that part of it which is distributed in the form of a film in areas of the combustion chamber close to its bottom.
    The purpose of the invention is to ensure reliable ignition and optimum combustion of the air-fuel mixture.

    This goal is achieved by the fact that the combustion chamber is provided with a flat bottom and narrowed neck, the point of impact of the jet on the wall of the combustion chamber is removed from the largest cross section of the combustion chamber to a distance of 10-15% of the diameter of this section, and the ignition device is located between the fuel jet and the wall of the combustion chamber, the distance between the points of intersection of the plane of the cylinder head and the axes of the ignition device and the shape of the barrel is 25% of the maximum cross section of the combustion chamber.
