In close contact with the opening and closing, the spark plug 70 is mounted in the combustion chamber of the cylinder head 20.

이와같이 구성되는 기관은 흡기행정시 흡기구가 열리고 연소실의 부압에 의해 연소용 공기와 연료가 흡기구를 통해 연소실로 흡입되며, 흡입된 공기 및 연료가 압축된 상태에서 점화플러그(70)에서 점화되는 전기불꽃에 의해 연소된다. 한편, 연소실에서 연소에 의해 발생되는 동력이 피스톤(30)을 구동하고, 피스톤(30)에 의해 크랭크축이 구동되어 회전력을 얻게 되며, 크랭크축에 의해 구동되는 캠축이 캠(40)을 통해 밸브(60)를 구동하여, 일정 주기로 밸브(60)가 연소실로 연통되는 흡기구와 배기구를 개폐하여 주므로, 새로운 혼합기를 흡입하고 연소된 가스가 배기되도록 한다.In the engine configured as described above, the inlet opening is opened during the intake stroke, and combustion air and fuel are sucked into the combustion chamber through the inlet by the negative pressure of the combustion chamber. Is burned by. 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 valve through the cam 40 By driving the 60, the valve 60 opens and closes the inlet and exhaust ports communicating with the combustion chamber at regular intervals, so that a new mixer is sucked in and the burned gas is exhausted.

여기에서, 종래 기관의 흡기구는 2개의 구멍으로 분리 형성되어 연소실에 연통되고, 각기 밸브가 개폐 가능하게 장치되며, 외측이 흡기다기관에 의해 공기청정기에 연통되어 있다.Here, the intake port of a conventional engine is formed into two holes and communicates with a combustion chamber, each valve is provided so that opening and closing is possible, and the outside is in communication with an air cleaner by the intake manifold.

이러한 종래 기관의 흡기구는, 2개의 구멍이 연소실에 연통되도록 하여 빠른시간에 많은 량의 연소공기 및 연료를 연소실로 흡입하도록 하고 있다.The intake port of such a conventional engine allows two holes to communicate with the combustion chamber so that a large amount of combustion air and fuel can be sucked into the combustion chamber in a short time.

이러한 종래 기관의 흡기구는, 흡기구의 구멍을 2개로 형성하여 빠른시간에 많은 량의 연소공기 및 연료를 연소실로 흡입하도록 하므로 기관의 성능이 향상되도록 하고 있으나, 흡기구 크기의 한계로 인해 출력증강의 제한이 따르는 문제점이 있었다.The intake port of the conventional engine is formed by two holes of the intake port to suck a large amount of combustion air and fuel into the combustion chamber in a short time to improve the performance of the engine, but limited output increase due to the limitation of the intake port size There was this following issue.

본 발명은 실린더헤드의 흡기구 및 흡기구에 장착되는 밸브의 구조를 개선하여 시간당 흡입공기의 량이 증가하도록 하므로 기관의 출력이 향상되도록 하는데 그 목적이 있다.The present invention is to improve the structure of the valve mounted on the inlet and inlet of the cylinder head to increase the amount of intake air per hour is to improve the output of the engine.
