    FIELD OF THE INVENTION The invention relates to engine-building, in particular, to ignition systems of pre-chamber and flare internal combustion engines.
    Known internal combustion engines include a cylinder block, a cylinder head, intake and exhaust valves, primary and secondary combustion chambers interconnected by a channel, and an ignition system equipped with first and second chambers separated by a diaphragm, connected to the distributor shaft, and the first the camera through the first channel is connected to the pre-throttle space of the inlet pipe, and the second is connected to the throttle space of the inlet pipe through the second channel til
    The lack of known engines is associated with the lack of devices for installing early ignition during starting and warming up the engine at a temperature below a predetermined level, as well as for installing later ignition in acceleration modes at a temperature below a predetermined level. This leads to an increase in the emission of harmful substances.
    The purpose of the invention is to reduce the toxicity of exhaust gases of automobile engines.
    The goal is achieved by the fact that the first channel has an air flow limiter, a shut-off valve and a valve that reacts to a change in engine temperature and is normally closed at a temperature above a predetermined level, and the second channel has a switching valve to communicate the second chamber with the intake manifold from the temperature of the engine.
    The drawing shows the internal combustion engine.
    The engine contains an interrupter 1 zigikigani, a membrane device 2 with two membrane chambers 3 and 4, an ignition control valve roller 5 connected to the membrane 6, twisted springs 7 and 8 located on the x-side of the membrane 6. Membrane chamber 4 is connected to the chamber through channel 9 10 valve 11 pressure delay (vacuum) and thermosensitive valve 12 bimetallic type. The valve 11 pressure delay and the temperature-sensitive valve 12 are connected via channel 13 with
    hole 14 in the throttle space of the intake manifold. The pressure delay valve 11 contains two chambers 10 and 15 separated by a wall 16. An air flow limiter 17 is provided in the dividing wall 16 for communicating the chambers 10 and 15 and a check valve 18 allowing air to flow through the aural stream only into chamber 10 from chamber 15 The heat-sensitive valve 12 is screwed into the cylinder block 19. The diaphragm chamber 3 is connected via a switch 20 to an electromagnetic multi-way valve (1 21 switching, actuated 1 by the output signal of a sensor 22 located in a water jacket 23. A multi-way valve 21 connects channel 20 to the inlet pipe 24, in which throttle valve 25 is placed , through channel 26 and gas filter 27,
    The device works as follows.
    When the temperature of the cylinder block 19 is below a predetermined level, the valve 12 interconnects the channels 9 and 13. When the temperature of the cylinder block 19 is above a predetermined level, the valve 12 blocks the communication between the channels 9 and 13.
    During the engine warm-up period, the coolant temperature in the jacket 23 is below a predetermined level, the channel 20 is open to the atmosphere, and atmospheric pressure is maintained in chamber 3. When the pressure in the diaphragm chamber 3 becomes equal to atmospheric, the ignition advance control roller 5 moves in the direction of the arrow K and more early ignition is established. When warming up the engine is completed and the temperature of the coolant in the jacket 23 is above a predetermined level, the valve 21 connects the channel 20 to the intake manifold 24 through channel 26 and gas filter 27. Under vacuum, the roller 5 moves in the direction opposite to arrow K, and later ignition is established.
    When the temperature of the cylinder block 19 is below a predetermined level, the diaphragm chamber 4 communicates with the throttle bore 14. When opening the damper 25 on the acceleration modes, the vacuum is transferred to the chamber 4; Pad 5 moves in the direction of arrow K, and early ignition is established.
    When the temperature of the cylinder block 19 becomes above a predetermined level, valve 12 divides channels 9 and 13,
    Suppose that throttle valve 25 is open by a certain amount and the vehicle is moving at a slow speed. Since bore 14 is in the pre-throttle space, atmospheric pressure is maintained in channel 13,
    chambers 10 and 15, valve 11 for the delay of the vacuum, channels 9 and the membrane chamber 4. When the throttle valve 15 opens further to create acceleration, the hole 14 is displaced behind the throttle valve 25 and the vacuum in the inlet pipe 24 is applied to the hole 14, However, at this moment Since the non-return valve 18 of the valve 11 is not diluted with the vacuum, the air from the diaphragm valve (Chamber 4 gradually flows out through the restrictor 17 and the opening 14 into the inlet pipe 24, B, then a certain ignition delay time is created, respectively The times and the alignment of the vacuum in the chamber 4 and in the hole 14.
    Since the pressure in the diaphragm chamber 4 does not become equal to the vacuum pressure instantaneously when the throttle valve 25 is open, the roller 5 of the ignition control valve moves in the direction of the arrow K. Accordingly, early ignition is not established during the initial acceleration period. When the throttles 25 are suddenly closed (switching the shift box the transmission, the atmospheric pressure applied to the opening 14 is transferred instantaneously to the chamber 4 through the check valve 18 of the vacuum valve, and as a result the valve is set later ignition.
