After the exercise, the vehicle is finally driven.
종래에 이와 같은 엔진 내에는 제1도에 도시한 바와 같이 실린더 헤드(1)에 형성된 포트(2)내에는 흡기밸브(3)가 설치되는데, 상기 흡기밸브(3)의 선단의 헤드부(3a)는 포트(2)의 선단에 고정 설치된 밸브 시이트(4)에 밀착되도록 구성되어 있다.Conventionally, such an engine is provided with an intake valve 3 in a port 2 formed in the cylinder head 1 as shown in FIG. 1, and the head portion 3a at the tip of the intake valve 3 is provided. ) Is configured to be in close contact with the valve seat 4 fixed to the tip of the port 2.
그러나, 이와 같이 구성된 종래의 흡기밸브는 엔진의 회전속도에 따라 흡기밸브의 개폐 면적이 동일하게 됨으로써 혼합기의 유속에 대응하지 못하게 됨은 물론 흡기 충진효율을 향상시키는데 한계가 있다고 하는 등의 여러 가지 문제점들이 있었다.However, the conventional intake valve configured as described above has various problems such as not being able to cope with the flow rate of the mixer by increasing the opening and closing area of the intake valve according to the rotational speed of the engine and improving the intake filling efficiency. there was.
본 고안은 상술한 바와 같은 종래 기술의 문제점들을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 흡기밸브의 선단에 헤드부를 탄성적으로 결합시켜 흡기의 유속에 따라 리프트량을 증가시킴과 동시에 흡기의 충진효율을 극대화하여 엔진의 성능을 향상시킬 수 있는 자동차용 엔진의 흡기밸브 구조를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to elastically couple the head to the front end of the intake valve to increase the lift amount in accordance with the flow rate of the intake and at the same time It is to provide an intake valve structure of an automobile engine that can improve the performance of the engine by maximizing the filling efficiency.
이와 같은 목적을 실현하기 위하여 이루어진 본 고안에 따른 자동차용 엔진의 흡기밸브 구조는 혼합기의 흡입이 이루어지는 포트와, 상기 포트내에 탄발설치된 밸브를 포함하는 자동차의 엔진에 있어서, 상기 밸브는 요홈부를 갖는 스템과, 상기 요홈부내에서 리프트 가능케 탄발설치된 헤드부를 더욱 포함하는 것을 특징으로 한다.The intake valve structure of the automobile engine according to the present invention made to achieve the above object comprises a port in which a mixer is sucked and a valve installed in the port, the valve having a stem having a recessed groove And, it characterized in that it further comprises a head portion which is installed in the groove to be lifted.
따라서, 흡기밸브가 스템부에 리프트 가능케 탄발설치된 헤드부로 구성됨에 따라 흡기의 유속에 따라 헤드부가 소정의 길이만큼 리프트됨으로써 흡기의 충진 효율이 증대됨과 동시에 엔진의 성능을 더욱 향상시키게 되는 등의 효과가 있다.Therefore, since the intake valve is composed of a head portion which is installed to be lifted to the stem portion, the head portion is lifted by a predetermined length according to the flow rate of the intake air, so that the filling efficiency of the intake air is increased and the performance of the engine is further improved. have.
이하, 본 고안의 바람직한 실시예를 첨부된 도면에 따라서 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도면 제2도에서 흡기밸브(30)는 요홈부(32a)가 형성된 스템(32)과, 상기 요홈부(32a)내에 스프링(34)으로 탄발설치된 헤드부(36)로 이루어지며, 상기 스템(32)의 선단에는 엔드부(38)가 용접 등의 수단으로 접합 고정되어 있다.In FIG. 2, the intake valve 30 is composed of a stem 32 having a groove portion 32a, and a head portion 36 installed with a spring 34 in the groove portion 32a. At the tip of the end 32, the end portion 38 is joined and fixed by welding or the like.
