본 발명은 자동차의 엔진의 피스톤에 관한 것으로, 특히 탑링의 부상을 방지하여 플루터링에 의한 오일소모를 감소하도록 한 자동차의 엔진의 피스톤에 관한 것이다.The present invention relates to a piston of an engine of a motor vehicle, and more particularly, to a piston of an engine of a motor vehicle which prevents injuries of the top ring to reduce oil consumption due to fluttering.

종래의 자동차에 있어서, 엔진이 고속으로 회전하면 피스톤이 폭발/흡입행정으로 하강과 상승을 반복하여 크랭크축을 운전시키게 된다. 피스톤이 폭발행정으로 하강시에는 제1도에 도시된 바와 같이 피스톤 헤드부의 최상측에 위치하는 톱 링과 제2링 사이의 가스압(P1)이 연소실압(P2)와 거의 같게 되는 시점이 존재하게 된다. 이 시점에서 톱 링에는 아직 관성력이 작용하고 있고, 그 외주측에서의 마찰력이 상향하여 작용하여 톱 링이 부상하게 되는 경우가 있다. 이 경우 톱 링이 부상하면서 윤활유를 함께 가지고 상승하게되어 오일의 소모가 증가하게 되는 문제점이 있었다.In a conventional vehicle, when the engine rotates at a high speed, the piston drives the crankshaft by repeatedly descending and raising the explosion / suction stroke. When the piston descends to the explosion stroke, as shown in FIG. 1, there exists a time point at which the gas pressure P1 between the top ring and the second ring located at the uppermost part of the piston head is substantially equal to the combustion chamber pressure P2. do. At this point, the inertia force still acts on the top ring, and the friction force on its outer circumferential side may act upward to cause the top ring to float. In this case, there is a problem that the top ring rises with lubricating oil while rising, so that the consumption of oil increases.

본 발명은 이러한 종래의 기술의 문제를 해결하기 위한 것으로, 톱 링의 부상을 방지하여 톱 링의 부상에 의한 오일의 소모를 감소시킬 수 있는 자동차의 엔진의 피스톤의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, and an object of the present invention is to provide a piston of an engine of an automobile that can prevent the injuries of the top ring and reduce the consumption of oil caused by the injuries of the top ring.

상기 목적을 달성하기 위하여, 본 발명의 자동차의 엔진의 피스톤은, 헤드부의 최상측에 위치하는 톱 링홈과, 상기 링홈에 삽입 설치되고, 한편 자화된 톱 링과, 상기 톱 링에 하향 자력을 작용하는 수단을 구비함을 특징으로 한다.In order to achieve the above object, the piston of the engine of the motor vehicle of the present invention is provided with a top ring groove located in the uppermost part of the head portion, and inserted into the ring groove, while a magnetized top ring and a downward magnetic force are applied to the top ring. It is characterized by having a means for.

한편, 상기 수단은 상기 링홈의 상측에 설치되어 상기 톱 링과 척력이 작용하는 제1자석편과, 상기 링홈의 하측에 설치되어 상기 톱링과 인력이 작용하는 제2자석편으로 구성됨을 특징으로 한다.On the other hand, the means is characterized in that it is composed of a first magnet piece installed on the upper side of the ring groove and the top ring and the repulsive force acts, and a second magnet piece installed on the lower side of the ring groove acts the top ring and attraction force. .

이하 본발명을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명의 자동차의 엔진의 피스톤을 나타낸 것으로, 피스톤(10)의 상부에는 톱 랜드(11)와 제2랜드(13)와 제3랜드(15)가 순차로 형성되어 있다. 상기 톱 랜드(11)와 제2랜드(13)사이에는 톱 링홈(16)이 형성되어 있고, 상기 톱 링홈(16)의 상부에는 상측은 N극을 갖고, 하측은 S극을 갖는 제1영구자석편(17)이 설치되고, 또한 상기 톱 링홈(16)의 하부에도 상측은 S극을 갖고, 하측은 N극을 갖는 제2영구자석편(18)이 설치되어 있다. 상기 톱링홈(16)에는 상측에는 S극을 갖고, 하측에는 N극을 갖도록 자화된 톱 링(19)이 삽입설치되어 있다. 따라서, 상기 톱 링홈(16)의 상부의 제1영구자석편(17)과 상기 톱 링홈(16)에 삽입된 톱 링(19)과의 사이에는 상호 반대의 자극이 마주하게 되어 척력이 작용하고, 상기 톱 링홈(16)의 하부의 제2영구자석편(18)과 상기 톱링(19)과의 사이에는 서로 같은 자극이 마주하게되어 인력이 작용한다. 따라서, 상기 톱링(19)은 항상 톱 링홈(16)의 하면에 밀착되도록 하향하는 힘을 받게된다. 폭발행정시, 상기 톱링(19)에 작용하는 관성력과 마찰력에 의해 피스톤(10)의 상부의 링홈(16)에 삽입 설치된 상기 톱 링(19)에 관성력과 마찰력에 의해 상향력이 작용하게 되어도, 위와 같이 톱 링을 하향시키는 자력에 의해 톱 링이 부상되는 것은 방지된다.2 shows the piston of the engine of the motor vehicle of the present invention. The top land 11, the second land 13, and the third land 15 are sequentially formed on the piston 10. As shown in FIG. A first ring groove 16 is formed between the top land 11 and the second land 13, and an upper side of the top ring groove 16 has an N pole and a lower end having an S pole. The magnet piece 17 is provided, and the 2nd permanent magnet piece 18 which has an S pole on the upper side and an N pole on the lower side is provided also in the lower part of the said top ring groove 16. As shown in FIG. The top ring groove 16 is provided with a magnetized top ring 19 so as to have an S pole at an upper side and an N pole at a lower side thereof. Therefore, mutually opposite magnetic poles face each other between the first permanent magnet piece 17 of the upper portion of the top ring groove 16 and the top ring 19 inserted into the top ring groove 16 so that the repulsive force acts. In addition, the same magnetic poles face each other between the second permanent magnet piece 18 and the top ring 19 at the lower portion of the top ring groove 16 so that the attraction force acts. Therefore, the top ring 19 is always subjected to downward force to be in close contact with the bottom surface of the top ring groove 16. When the explosion stroke, even if the upward force is applied to the top ring 19 inserted into the ring groove 16 of the upper portion of the piston 10 by the inertial force and friction force acting on the top ring 19, As described above, the top ring is prevented from being lifted by the magnetic force that lowers the top ring.

이상, 설명한 바와 같이, 본 발명에 따르면, 자력에 의해 톱 링에 하향력을 발생시킴으로서 톱 링이 부상하는 것을 방지하여 톱 링의 부상에 따른 오일의 소모를 감소시킬 수 있는 효과가 있다.As described above, according to the present invention, by generating a downward force on the top ring by magnetic force, it is possible to prevent the top ring from rising, thereby reducing the consumption of oil caused by the top ring.
