Abstract

흡, 배기 밸브가 동시에 열려있는 오버 랩 구간에서 혼합기 및 배기가스가 흡기포트나 배기포트로 역류하는 것을 방지하고, 연속속도를 증대시키기 위하여, 흡기밸브에 의해 개폐되는 흡기포트 및 배기밸브에 의해 개폐되는 배기포트가 형성된 실린더 헤드와, 상기한 실린더 헤드의 아래측에 고정되며 보어를 형성하고 있는 실린더 블럭과, 상기한 보어에 이동가능하게 배치되며 상기 실린더 헤드의 저면과 함께 연소실을 형성하는 피스톤을 포함하며, 상기한 실린더 헤드의 저면은 흡기밸브 시이트 면과 배기밸브 시이트 면이 상이한 각도로 형성되어 이들 시이트 면 교차부위에 단부를 형상하고 있으며, 상기한 피스톤의 상면은 배기밸브 시이트 면과 동일한 경사각으로 이루어지는 피스톤 제1경사면과, 이 제1경사면과 반대방향으로 경사진 피스톤 제2경사면과, 실린더 헤드의 저면과 평행한 수평면을 포함하는 내연기관의 연소실 구조를 제공한다.In order to prevent the mixer and exhaust gas from flowing back to the intake port or the exhaust port in the overlap section in which the intake and exhaust valves are open at the same time, and to increase the continuous speed, the intake port and the exhaust valve opened and closed by the intake valve are opened and closed. A cylinder head having an exhaust port formed therein, a cylinder block fixed to the lower side of the cylinder head and forming a bore, and a piston arranged to be movable in the bore and forming a combustion chamber together with a bottom surface of the cylinder head. And the bottom surface of the cylinder head is formed at different angles between the intake valve sheet surface and the exhaust valve sheet surface to form end portions at these sheet surface intersections, and the upper surface of the piston has the same inclination angle as the exhaust valve sheet surface. A piston first inclined surface and a piston inclined in a direction opposite to the first inclined surface A combustion chamber structure of an internal combustion engine is provided comprising a two inclined surfaces and a horizontal surface parallel to the bottom of the cylinder head.
