    As is well known, the internal combustion engine burns the mixer sucked into the combustion chamber, and causes the piston to move up and down linearly with the explosive force generated by the explosion, and converts the linear reciprocating motion into rotational motion as a crank mechanism to obtain rotational power. An example is the engine.
    In such an internal combustion engine, the intake / exhaust valve is moved up and down by a predetermined valve mechanism operated by a camshaft to supply the mixer to the combustion chamber or discharge the combusted gas by opening and closing the intake and exhaust ports in a timely manner. It will play a role.
    Such an intake / exhaust valve is always exposed to a high temperature heat source because the bottom of the valve head is installed in contact with the combustion chamber so as to form part of the combustion chamber.
    Accordingly, when the mixer burns in the combustion chamber, carbon sludge in the combustion gas and carbon sludge generated by the combustion of inevitably leaked lubricating oil are deposited on the head and neck of the valve.
    In this case, the carbon deposit acts as a hot spot during combustion, which causes abnormal combustion, thereby promoting deterioration and aging of the engine, and the carbon deposit attached to the neck of the intake valve is a smooth flow of intake air supplied to the combustion chamber. Will interfere with the power output.

And a torch which protrudes into the intake port and the exhaust port to respectively inject gas fuel toward the valve head portion of the intake / exhaust valve as the operation switch is turned on, and the operation switch is turned on. As a power supply is characterized in that the ignition plug is provided on one end of the torch to ignite the gas fuel injected from the torch.
    The apparatus includes an ECU for performing a control operation for removing carbon deposits when the operation switch is turned on and an engine start switch is turned off, a timer for measuring a required time according to the control operation of the ECU, and a gas. A gas tank in which fuel is stored, a solenoid valve for supplying gas fuel from the gas tank to the torch for a preset time under the control of the ECU, and ON for a preset time under the control of the ECU And a high pressure generator for generating power and generating a high voltage with the power supplied from the relay to generate a spark plug in the spark plug.

    BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view showing an installation state of the present invention. As shown, the present invention is directed to an internal combustion engine in which an intake port 4 and an exhaust port 6 are formed in a cylinder head 2. , The operation switch 20 (see FIG. 2) to be operated to remove carbon deposits accumulated in the exhaust valves 8 and 10 and the operation switch 20 as the operation switch 20 is turned on. Torch 30 and 31 protruding into the intake port 4 and the exhaust port 6 so as to inject the gas fuel toward the valve head portion of the 8 and 10, and the operation switch 20 Consists of an ignition plug 40, 41 provided at one end of the torch 30, 31 to ignite the gas fuel injected from the torch (30, 31) as the power is supplied (ON) do.
    2 is a circuit diagram showing the control system of the present invention as described above, wherein the configuration of the control cylinder of the present invention is determined by the control of the electronic control unit (ECU) according to the operation of the operation switch 20. It is characterized by the ignition for a time to remove the carbon sludge deposited on the intake and exhaust valves (8, 10), the old components are ECU (50), timer (60), gas tank (70), It comprises a solenoid valve 80, a relay 90 and a high pressure generating unit (100).
    The ECU 50 performs a control operation for removing carbon deposits when the operation switch 20 is turned on and the engine start switch 12 is turned off. In this case, the engine start switch 12 If the engine to which the present invention is applied corresponds to the ignition switch of the vehicle, the start switch 12 is off means that the ignition switch is moved from the starting contact to the power contact. In other words, it corresponds to a state where the engine is stopped and power is supplied to each electric device.
    The timer 60 measures the required time according to the control operation of the ECU 50 and applies the signal to the ECU 5.
    The gas tank 70 is a container filled with a predetermined gas fuel, and supplies gas fuel to the torch 30, 31, wherein the gas fuel uses a clean fuel such as propane gas or butane gas. .
    The solenoid valve 80 supplies gas fuel from the gas tank 70 to the torch 30, 31 for a preset time by the control of the ECU 50. It is installed in the middle of the gas pipe connecting the torch (30, 31) to open and close the gas pipe in response to the operation signal of the ECU (50).
    Accordingly, the opening time of the solenoid valve 80 is set in advance in the ECU 50.
    The relay 90 is turned on for a preset time under the control of the ECU 50 to electrically connect the spark plugs 40 and 41 to the power supply unit.
    Accordingly, in the ECU 50, not only the opening time of the solenoid valve 80 but also the ON operation time of the relay 90 are set in advance, and only the operation time of the relay 90 is the solenoid valve ( It is shorter than the opening time of 80).
    The high pressure generating unit 100 is to generate a fire to the spark plugs (40, 41) by the power supplied from the relay (90), thereby the gas fuel injected from the torch (30, 31) Ignite.
    The operation of the present invention made as described above will be described.
    The operation of the carbon deposit removal apparatus of the internal combustion engine valve of the present invention will be described.
    In order to remove the carbon deposits, first, the engine must be operated while the engine is stopped. When the start switch 12 for engine operation is turned off, the operation switch 20 is turned ON to operate the ECU ( 50 operates the timer 60 and opens the solenoid valve 80 and turns on the contact of the relay 90.
    Then, the gas fuel charged in the gas tank 70 passes through the solenoid valve 80 and is supplied to the torch 30 and 31 which protrudes in the intake and exhaust ports 4 and 6, and is injected. The power is supplied to the high pressure generating unit 100, and the high pressure generating unit 100 generates a spark by applying a high voltage to the spark plugs 40 and 41.
    As a result, the gas fuel injected from the torch 30 and 31 is ignited, and thus the flame is radiated from the intake and exhaust valves 8 and 10, and the sludge accumulated in the intake and exhaust valves 8 and 10. Will be burned and removed.
    At this time, the ECU 50 detects the time of the timer 60 at the beginning of flame emission, and then turns off the contact point of the relay 90 after a predetermined operation time of the spark plugs 40 and 41 passes. The power supplied to the spark plugs 40 and 41 is cut off, and the torch 30 and 31 continue to radiate a flame to remove the sludge of the intake and exhaust valves 8 and 10 for a predetermined time. Accordingly, it does not inhibit the normal operation of the engine, and also induces a smooth flow of intake and exhaust, thereby contributing to the increase in engine output.
    Then, when the ECU 50 confirms that the flame emission time set by the timer 60 has passed, the ECU 50 switches the solenoid valve 80 to torch 30, 31 from the gas tank 70. ) To cut off the gas fuel supplied to the flame, thereby stopping the flame emission.
    As described above, according to the present invention, when sludge is formed in the intake and exhaust valves, the sludge is removed by gas fuel, thereby achieving the normal operation of the engine and the desired intake flow.
    Furthermore, this sludge removal operation can be made simply by a switch operation.
