    In an internal combustion engine, an injection hole is provided in the cylinder head to inject narrow streams of air towards the spark gap, particularly during idling and lowload running conditions. The injected air is 5 to 30% by weight of the intake fuel-air mixture provided via the intake manifold and creates a swirl or turbulence thereby increasing combustibility. The hole is connected via a sub-intake passage to the main air intake passage upstream of the venturi in the carburetor or between the venturi and throttle valve.

The longitudinal axis of the nozzle 11 is inclined to the surface 15 of the piston 4 and is directed to the spark gap 14 of the spark plug 13. The drive mechanism of the control valve 12 40 is made with the possibility of opening the latter during the suction stroke of the piston 4 and contains a rocker arm 16 in contact with the cam 17 of the camshaft 18. An additional 45 inlet channel 10 through a pipe 19 Communicated with ~ carburetor 1 on the section between the Venturi nozzle 2 and the throttle valve 3 (Fig. 2), and the Venturi nozzle 2 is connected to the sprayer 20 of the main dosing system of the carburetor 1, and at the throttle valve. ki 3 made 'channels 21 of the idle system. The carburetor 1 has an air cleaner 55 located at its inlet. ' Tel. 22.
    An exhaust channel 23 is made in the head, the last and main inlet channel 8 having valves (not shown in the drawing) located in the head 1 and driven from the camshaft 18.

In this regard, a strong vortex motion of the combustible mixture in the combustion chamber 7 is created, and at the same time, the air leaving the nozzle 11 is mixed with the combustible mixture, providing dispersion under conditions of uneven distribution of fuel. Since the air stream leaving the nozzle 11 is directed to the spark gap 14 of the spark plugs 13, the exhaust gases located in the latter are removed and supplied to it. fresh combustible mixture.
    Since at the moment of supply of the spark in the combustion chamber 7 there is a vortex movement of the charge of the combustible mixture having a significant stratification, its rapid combustion is ensured and misfire is prevented, in connection with which the reliability of the engine increases, and the fuel consumption last decreases.
    When the engine is operating under medium and nominal load conditions, through 5 an additional inlet channel a fuel-air mixture of almost the same composition as the combustible mixture entering through the main inlet channel is supplied.
    Thus, the vortex movement of the charge of the combustible mixture in the cylinder 5 of the engine is ensured; however, due to its uniformity, increased power indices of the engine are ensured at medium and nominal loads. 15 Thus, this embodiment of the internal combustion engine provides an increase in the reliability of its operation.
