본 고안은 자동차의 흡기밸브 회전장치에 관한 것으로 보다 상세하게는 밸브의 상하 왕복 운동 중 밸브가 열림과 동시에 회전운동이 가능하도록 한 자동차의 흡기밸브 회전장치에 관한 것이다.The present invention relates to an intake valve rotation apparatus of an automobile, and more particularly, to an intake valve rotation apparatus of an automobile, which enables the rotational movement at the same time the valve is opened during the vertical reciprocating movement of the valve.
근래의 엔진동향은 엔진의 고성능화 및 엄격한 배기규제에 대응하기 위하여 정밀한 전자제어에 의해 최적화된 연료분사 방식을 채택하고 있으나, 이러한 엔진에서는 워엄업시 배기가스의 저감을 목적으로 기화기 방식 엔진보다 희박한 혼합기를 사용하고 있으므로 기존 기화기 방식엔진에서 부각되지 않았던 흡기 밸브 디포지트에 의한 공연비가 더욱 희박해짐에 따라 발생되는 워엄업전 운전성의 악화가 새로운 문제로 대두되기 시작했다.Recent engine trends have adopted fuel injection methods optimized by precise electronic control to cope with high engine performance and strict emission regulations.However, these engines use a thinner mixer than carburetor engines to reduce exhaust gas during warm up. As the air-fuel ratio due to the intake valve deposit, which has not been highlighted in the existing carburetor engine, is becoming thinner, deterioration of pre-warm-operability caused by the carburetor engine has become a new problem.
따라서 전자제어에 의한 연료분사방식을 채택한 엔진에 있어서 흡기밸브 상면에 디포지트 발생을 방지할 수 있는 장치가 필요하다.Therefore, there is a need for an apparatus capable of preventing deposits on the upper surface of an intake valve in an engine employing a fuel injection method by electronic control.
제2도는 종래기술의 흡기밸브가 장착된 상태를 나타내는 도면으로서, 캠(A)의 회전운동에 따라 직선왕복운동하여 선택적으로 개폐가능한 흡기밸브(B)가 흡기매니홀드(C)의 끝단에 고정설치되어 혼합기를 실린더(D)에 충진할 수 있도록 되어 있다.2 is a view showing a state in which the intake valve of the prior art is mounted, the intake valve (B) which can be selectively opened and closed by linear reciprocating movement according to the rotational movement of the cam (A) is fixed to the end of the intake manifold (C) It is installed so that the mixer D can be filled.
또한 캠(E)에 의해 직선왕복 운동 가능한 배기밸브(F)가 배기매니홀드(G)입구에 고정설치되어 연소된 배기가스를 배출토록 되어있다.In addition, an exhaust valve F capable of linear reciprocation by the cam E is fixedly installed at the inlet of the exhaust manifold G to discharge the exhaust gas.
도면 중 미설명부호(H)는 피스턴을 나타내고 있다.In the figure, reference numeral H denotes a piston.
이와 같이 구성되는 종래기술은 캠(A)의 회전에 따라 직선왕복 운동하는 흡기밸브(B)는 탄성부재(도시생략)의 신축작용에 의해 조금씩 자체회전 가능하지만 아주 미미하기 때문에 고온에 의한 산화된 엔진오일의 성상 또는 연료의 성분 및 연소실내의 생성그을음으로 인하여 흡기밸브(B)상면에 디포지트가 형성된다.In the prior art configured as described above, the intake valve B reciprocating linearly in accordance with the rotation of the cam A is self-rotating little by little due to the elasticity of the elastic member (not shown). The deposit is formed on the upper surface of the intake valve B due to the properties of the engine oil or the components of the fuel and the soot produced in the combustion chamber.
따라서 상기한 디포지트가 스폰지처럼 연료를 흡수하여 가속시에는 혼합기가 희박해지고, 감속시에는 이 흡수된 연료가 흡기매니홀드(C)의 부압에 의해 증발되어 연소실내에 유입되므로 더욱 농후해지게 된다.Therefore, the deposit absorbs the fuel like a sponge, and the mixer is lean at the time of acceleration, and at the time of deceleration, the absorbed fuel is evaporated by the negative pressure of the intake manifold (C) and is more concentrated. .
이러한 공연비의 차이가 워엄업전에는 더욱 심하게 나타나서 헤지테이션(Hesitation), 스텀블(Stumble)등이 디포지트 발생초기에 대두된다.The difference in air-fuel ratio is even more severe before warm-ups, so hesitation and stumble emerge early in the generation of deposits.
또한 이러한 형상은 이미션의 증가 및 연비의 악화를 초래하여 디포지트가 더욱 심해지면 연소실 내로 공기 흡입이 방해되어 엔진의 출력 또한 저하되게 되어 주행성이 떨어지는 제반 문제점이 내재되어 있다.In addition, such a shape causes an increase in emission and deterioration of fuel economy, and when the deposit becomes more severe, intake of air into the combustion chamber is disturbed and the output of the engine is also lowered.
본 고안은 상기한 바와 같이 종래기술의 문제점을 해소하기 위해 안출된것으로서, 본 고안의 목적은 밸브의 상하왕복 운동 중 밸브가 열림과 동시에 회전운동이 가능하도록 함으호써 디포지트 발생을 미연에 방지하고 연비를 향상시켜 이미션 저감 및 주행성을 향상시킬 수 있는 자동차의 흡기 밸브 회전장치를 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 prevent the occurrence of deposit by allowing the valve to rotate simultaneously with the opening and closing of the valve up and down The present invention provides an intake valve rotating device for a vehicle that can improve fuel economy and reduce emission and runability.
상기한 바와 같은 목적을 실현하기 위해 본 고안은 흡기밸브의 엔드부 외주에 베벨기어에 형성되고, 상기한 엔드부가 마찰접촉된 캠의 장경에 상기한 베벨기어와 치차결합 될 수 있도록 동일 방향으로 형성된 회전운동부가 형성되어 캠의 회전에 따라 흡기밸브가 열림과 동시에 회전가능하도록 함을 특징으로 하는 자동차의 흡기밸브 회전장치를 제공한다.In order to realize the object as described above, the present invention is formed in the bevel gear on the outer periphery of the end portion of the intake valve, and the end portion is formed in the same direction so that the end portion can be geared with the bevel gear in the long diameter of the cam in friction contact. It is provided with a rotary motion portion is provided with the intake valve rotating apparatus of the vehicle, characterized in that the intake valve is rotatable and rotatable simultaneously with the rotation of the cam.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 본 고안의 자동차의 흡기밸브 회전장치의 구성을 나타내는 도면으로 제1(a)도는 정면도, 제1(b)도는 측면도로서, 흡기밸브(1)의 앤드부(2) 외주에 베벨기어(3)가 형성되고, 상기한 앤드부(2) 탄성부재(4)로 탄발지지 되어 있다.1 is a view showing the configuration of the intake valve rotating apparatus of a vehicle of the present invention, the first (a) is a front view, the first (b) is a side view, the bevel on the outer periphery of the end portion 2 of the intake valve (1) The gear 3 is formed and is elastically supported by the above-mentioned end part 2 elastic member 4.
상기한 엔드부(2)에 마찰 접촉된 캠(5)의 장경에 상기한 베벨기어(3)와 치차결합 가능하도록 동일 방향으로 형성된 회전운동부(6)가 형성되어 캠(5)의 회전에 따라 회전운동부(6)와 베벨기어(3)의 구름접촉에 의해 흡기밸브(1)가 열릴때 회전하도록 되어 있다.In the long diameter of the cam 5 frictionally contacted with the end portion 2, a rotary motion portion 6 is formed in the same direction so as to be geared with the bevel gear 3, and the cam 5 rotates. The intake valve 1 is rotated by the rolling contact between the rotary motion part 6 and the bevel gear 3.
이와 같이 구성되는 본 고안의 자동차의 흡기밸브 회전장치는 캠(5)이 회전되어 장경이 흡기밸브(1)의 엔드부(2)에 마찰접촉되면 상기한 흡기밸브(1)는 탄성부재(4)의 탄성력을 이기고 열림과 동시에 베벨기어(3)와 캠(5)의 회전운동부(6)가 구름접촉되어 회전된다.In the intake valve rotating apparatus of the present invention configured as described above, when the cam 5 is rotated so that the long diameter is frictionally contacted with the end portion 2 of the intake valve 1, the intake valve 1 is an elastic member 4. The bevel gear 3 and the rotary motion part 6 of the cam 5 are rotated in contact with the cloud at the same time as opening and defeating the elastic force.
이러한 상태에서 캠(5)이 계속회전되어 흡기밸브(1)의 엔드부(2)에 마찰접속되면 흡기밸브(1)는 탄성부재(4)의 탄성력에 의해 복원되어 닫히게 된다.In this state, when the cam 5 is continuously rotated and frictionally connected to the end portion 2 of the intake valve 1, the intake valve 1 is restored and closed by the elastic force of the elastic member 4.
이와같이 흡기밸브(1)가 열리면서 회전하기 때문에 분사되는 연료는 실린더(도시생략)내에 균일하게 무화시켜 연비를 향상시킴은 물론 디포지트 발생을 미연에 방지하여 배출가스의 유해성분을 저감시키고, 엔진의 출력이 증대되 주행성이 향상되는 이점이 있다.Since the intake valve 1 rotates as described above, the injected fuel is uniformly atomized in a cylinder (not shown) to improve fuel efficiency and to prevent deposits in advance, thereby reducing harmful components of the exhaust gas, There is an advantage that the output is increased and the runability is improved.
