본 고안은 차량의 실린더헤드에 관한 것으로, 특히 실린더헤드의 연소실을 형성하는 원뿔형의 벽면에 계단식 돌출면을 형성하는 동시에 배기포트위치에 타원형 가이드를 형성하여 주므로써, 소용돌이발생으로 유속증대 및 저항감소시켜 미연소가스저감 및 잔류배기가스의 저감을 도모하도록 한 차량의 실린더헤드형상구조에 관한 것이다.The present invention relates to a cylinder head of a vehicle, and in particular, by forming a stepped projecting surface on the conical wall forming the combustion chamber of the cylinder head, and forming an elliptical guide at the exhaust port position, thereby increasing the flow velocity and reducing the resistance by vortex generation. The present invention relates to a cylinder head shape structure of a vehicle designed to reduce unburned gas and reduce residual exhaust gas.
종래에는 제3도 및 제4도와 같이, 실린더헤드(10)는 흡기포트(11)와 배기포트(12)가 형성되어 연소실(13)과 연통하도록 되어 있으며, 연소실(13)의 형상은 원뿔형으로 되어 있다.Conventionally, as illustrated in FIGS. 3 and 4, the cylinder head 10 has an intake port 11 and an exhaust port 12 formed therein to communicate with the combustion chamber 13, and the shape of the combustion chamber 13 is conical. It is.
즉, 원뿔형의 연소실(13)의 벽면(13a)은 평면형으로 되어 있으며, 평단면상 진원으로 형성되어 있어 혼합기의 흡입시 소용돌이를 발생시키지 못하여 불균일하게 혼합되므로 미연소가스의 발생원인이 되었으며, 이로인해 폭발압력의 저하로 배기가스의 배출시 유속이 감소되는 동시에 저항이 커서 연소실(13)내에 배기가스가 잔류하게 되는 문제점이 있었다.That is, the wall surface 13a of the conical combustion chamber 13 has a flat shape, and is formed in a circular cross-section, so that it does not generate a vortex when the mixer is inhaled and is mixed unevenly, thereby causing unburned gas. Due to the lowering of the explosion pressure, the flow rate of the exhaust gas is reduced, and the resistance is large, thereby causing the exhaust gas to remain in the combustion chamber 13.
본 고안은 이러한 종래의 문제점을 해결하고자 하는 것으로, 실린더헤드의 연소실을 형성하는 원뿔형의 벽면에 계단식 돌출면을 형성하는 동시에 배기포트위치에 타원형 가이드를 형성하여 주므로써, 소용돌이발생으로 유속증대 및 저항감소시켜 미연소가스저감 및 잔류배기가스의 저감을 도모하고자 차량의 실린더헤드형상구조를 제공하는 데 그 목적이 있다.The present invention is to solve this conventional problem, by forming a stepped projecting surface on the conical wall surface forming the combustion chamber of the cylinder head, and at the same time to form an elliptical guide in the exhaust port position, increase the flow rate and resistance by vortex generation The purpose of the present invention is to provide a cylinder head shape structure of a vehicle in order to reduce unburned gas and reduce residual exhaust gas.
본 고안은 이러한 목적을 달성하기 위하여, 흡기포트 및 배기포트가 형성된 실린더헤드의 원뿔형 연소실과, 연소실의 벽면에 계단식으로 연속 연결되게 돌출시켜 흡입되는 혼합기가 균일한 혼합기로 형성되도록 소용돌이를 발생하는 돌출면과, 배기포트측의 돌출면에 타원형으로 돌출시켜 배기가스의 저항을 감소시키는 가이드로 차량의 실린더헤드형상구조를 구성한 것이 본 고안의 특징이다.In order to achieve the above object, the present invention provides a conical combustion chamber of a cylinder head in which an intake port and an exhaust port are formed, and a protrusion which generates a vortex so that a mixer that is sucked by projecting continuously connected to the wall surface of the combustion chamber is formed into a uniform mixer. It is a feature of the present invention that the cylinder head-shaped structure of the vehicle is constituted by a surface and a guide that protrudes elliptically on the protruding surface of the exhaust port side to reduce the resistance of the exhaust gas.
이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도면 제1도 및 제2도는 본 고안의 실시예로서, 흡기포트(11) 및 배기포트(12)가 형성된 실린더헤드(10)의 원뿔형 연소실(13)과, 연소실(13)의 벽면에 계단식으로 연속 연결되게 돌출시켜 흡입되는 혼합기가 균일한 혼합기로 형성되도록 소용돌이를 발생하는 돌출면(14)과, 배기포트(12)측의 돌출면에 타원형으로 돌출시켜 배기가스의 저항을 감소시키는 가이드(15)로 차량의 실린더헤드형상구조를 구성한다.1 and 2 are embodiments of the present invention, in which the inlet port 11 and the exhaust port 12 are formed in the conical combustion chamber 13 of the cylinder head 10 and the wall surface of the combustion chamber 13 in a stepwise manner. Protruding surface 14 for generating a vortex so that the mixer to be sucked in continuous connection to form a uniform mixer and the guide (15) to protrude in an oval shape on the protruding surface on the exhaust port 12 side to reduce the resistance of the exhaust gas (15). ) To form the cylinder head shape of the vehicle.
이와같이 구성된 본 고안은, 흡입행정과 압축행정시 흡입된 혼합기는 연소실(13)의 계단식 돌출면(14)에 의하여 유속이 증가하게 되며, 또한 연소실(13)의 양측 돌출면(14)에 각각 다른 각도(θ1θ2또는 θ1θ2)로 형성하여 유속의 저항을 유도하는 동시에 소용돌이를 발생시키게 된다.The present invention configured as described above, the mixer sucked during the suction stroke and the compression stroke is increased in the flow rate by the stepped projection surface 14 of the combustion chamber 13, and also different angles on both side projection surface 14 of the combustion chamber 13 (θ 1 θ 2 or θ 1 θ 2 ) to induce a resistance of the flow velocity and to generate a vortex.
또한 배기행정시 배기밸브가 순간적으로 열릴 때 연소실(13)의 벽면에 의한 저항을 줄이기 위하여 배기포트(12)측의 돌출면(14)을 타원형의 가이드(15)로 형성하여 주므로서 배기가스의 자연스런 배출을 유도하도록 하였다.In addition, in order to reduce the resistance caused by the wall surface of the combustion chamber 13 when the exhaust valve is opened momentarily during the exhaust stroke, the protruding surface 14 on the exhaust port 12 side is formed as an elliptical guide 15, Induce natural emissions.
이와같이 본 고안은 실린더헤드의 연소실을 형성하는 원뿔형의 벽면에 계단식 돌출면을 형성하는 동시에 배기포트위치에 타원형 가이드를 형성하여 주므로써, 소용돌이발생으로 유속증대 및 저항감소시켜 미연소가스저감 및 잔류배기가스의 저감을 도모할 수 있는 것이다.In this way, the present invention forms a stepped projecting surface on the conical wall that forms the combustion chamber of the cylinder head, and simultaneously forms an elliptical guide at the exhaust port position, thereby increasing the flow rate and reducing the resistance by vortex generation, thereby reducing unburned gas and remaining exhaust. The gas can be reduced.
