본 발명은 자동차 기관의 연소실에 공기를 분사하는 공기인젝터(air-injector)의 장착구조에 관한 것으로, 흡기구 내부에서 연료인젝터 측부에 공기인젝터를 장치하여 분사연료의 분무가 빠르도록 하므로 기관의 출력이 향상되도록 한 것에 관한 것이다.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.
일반적으로 기관은 도 1에 도시되는 바와 같이, 흡기구와 배기구가 연소실과 연통되게 형성되는 실린더헤드(20)가 피스톤(30)이 장착되는 실린더블록(10)의 상부에 장치되어, 실린더헤드(20)의 연소실에 흡기구와 배기구를 각기 일정 주기로 개폐하여 주는 밸브(40)가 코일스프링에 상향으로 탄지되고, 캠축의 캠에 의해 개폐가능하게 밀착되며, 흡기구에 연료를 분사하는 연료인젝터(50)가 장착되어 있다.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.
이와같이 구성되는 기관은 흡기행정시 흡기구가 열리고, 전자제어장치에 의해 제어되는 연료인젝터(50)가 연료를 연소실쪽으로 분사함과 동시에 연소실의 부압에 의해 연소용 공기가 함께 연소실로 흡입되어 연소된다. 한편, 연소실에서 연소에 의해 발생되는 동력이 피스톤(30)을 구동하고, 피스톤(30)에 의해 크랭크축이 구동되어 회전력을 얻게 되며, 크랭크축에 의해 구동되는 캠축이 캠을 통해 밸브(40)를 구동하여, 일정 주기로 밸브(40)가 연소실로 연통되는 흡기구와 배기구를 개폐하여 주므로, 새로운 혼합기를 흡입하고 연소된 가스가 배기되도록 한다.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.
여기에서, 종래 연료인젝터의 장착구조는 흡기구의 내측에서 연료인젝터(50)의 분사노즐이 연소실쪽으로 향하여 장치되고, 연료펌프에 연통되게 연결되며, 전자제어장치에 의해 일정시기에 일정시간동안 연료를 분사하도록 장치되어 있다.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.
이러한 종래 연료인젝터의 장착구조는, 밸브(40)가 열렸을 때 전자제어장치의 제어에 의해 연료인젝터(50)가 연료를 분사하게 되며, 이때 분무된 연료가 흡입되는 공기와 함께 열린 밸브(40) 사이의 흡기구를 통해 연소실로 흡입되게 된다.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.
이러한 종래 연료인젝터의 장착구조는, 연료인젝터에서 분사된 연료가 밸브에 부딪히며 연소실로 흡기되기 때문에, 충진효율이 떨이지고, 많은 량의 연료가 흡기구에서 낭비되는 문제점이 있었다.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.
본 발명은 연료인젝터 측부에 압축공기를 분사하는 공기인젝터를 장치하여, 연료인젝터에서 분사되는 연료가 빠르게 분무되고 빠르게 연소실로 흡입되도록 하므로, 충진효율이 향상되어 기관의 출력이 향상되도록 하는데 그 목적이 있다.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.
