    Mounting Structure of Air Injector
    The present invention relates to a mounting structure of an air injector (air-injector) for injecting air into the combustion chamber of the automobile engine, the air injector is installed on the fuel injector side in the inlet port so that the spraying of the injection fuel is fast, so It's about making things better.
    In general, as shown in FIG. 1, a cylinder head 20 having an inlet and an exhaust port communicating with a combustion chamber is installed on an upper portion of a cylinder block 10 on which a piston 30 is mounted. The valve 40 which opens and closes the inlet and the exhaust port in the combustion chamber at regular intervals, respectively, is upwardly supported by the coil spring, and is tightly opened and closed by the cam of the camshaft, and the fuel injector 50 which injects fuel into the inlet is It is installed.
    In the engine configured as described above, the intake port is opened during the intake stroke, and the fuel injector 50 controlled by the electronic controller injects fuel into the combustion chamber, and the combustion air is sucked into the combustion chamber by the negative pressure of the combustion chamber and combusted. On the other hand, the power generated by the combustion in the combustion chamber drives the piston 30, the crankshaft is driven by the piston 30 to obtain a rotational force, the camshaft driven by the crankshaft through the cam valve 40 Drive the valve 40 to open and close the intake port and the exhaust port which communicate with the combustion chamber at a predetermined cycle, so that a new mixer is sucked and the burned gas is exhausted.
    Here, the mounting structure of the conventional fuel injector is equipped with the injection nozzle of the fuel injector 50 toward the combustion chamber from the inside of the inlet port, connected in communication with the fuel pump, and by the electronic control device for a predetermined time at a predetermined time. It is equipped to spray.
    In the conventional fuel injector mounting structure, when the valve 40 is opened, the fuel injector 50 injects fuel by the control of the electronic controller, and the valve 40 opened together with the air in which the sprayed fuel is sucked. It is sucked into the combustion chamber through the intake port therebetween.
    In the conventional fuel injector mounting structure, since the fuel injected from the fuel injector hits the valve and is taken into the combustion chamber, the filling efficiency is lowered, and a large amount of fuel is wasted in the intake port.
    The present invention is equipped with an air injector for injecting compressed air to the fuel injector side, so that the fuel injected from the fuel injector is quickly sprayed and sucked into the combustion chamber, the filling efficiency is improved to improve the engine output have.

    First, as shown in FIG. 2, the cylinder head 20, in which the inlet and the exhaust port are formed in communication with the combustion chamber, is mounted on the upper portion of the cylinder block 10 on which the piston 30 is mounted. A valve 40 which opens and closes the inlet and the exhaust port in the combustion chamber at a predetermined cycle, respectively, is upwardly supported by the coil spring, and is tightly opened and closed by the cam of the camshaft, and injects fuel into the inlet. Is fitted.
    However, in the present invention, the air injector 60 connected to the air compressor 70 inside the intake port in which the fuel injector 50 is mounted and controlled by the electronic controller 80 is directed toward the fuel injector 50 and the combustion chamber. The basic features of the technical construction.
    According to the present invention configured as described above, when the valve 40 is opened during the intake stroke, combustion air is sucked through the intake port by the negative pressure of the combustion chamber, and the fuel injector 50 is driven into the combustion chamber by the control of the electronic controller 80. The fuel is directly injected, and at the same time, the air injector 60 injects compressed air toward the fuel injector 50 and the combustion chamber, and the sprayed fuel is pumped together with the sucked air into the combustion chamber.
    The present invention allows the fuel injected from the fuel injector 50 to be sucked into the combustion chamber by the negative pressure of the combustion chamber and the compressed air injected from the air injector 60, thereby improving the filling efficiency of the fuel.
    The present invention constructed and operated as described above is equipped with an air injector for injecting compressed air to the fuel injector side, so that the fuel injected from the fuel injector is quickly sprayed and sucked into the combustion chamber, thereby improving the filling efficiency of the engine. This has the effect of improving the output.
