본 발명은 가변밸브 타이밍장치와 오일 제어 밸브 사이에 설치되어 상기 가변 밸브 타이밍 장치의 진각실과 지각실로 공급되는 오일의 양을 가변적으로 조절하여 사용할 수 있는 차량용 가변 밸브 듀레이션 장치에 관한 것이다.The present invention relates to a variable valve duration apparatus for a vehicle that is provided between a variable valve timing device and an oil control valve so as to variably adjust the amount of oil supplied to the advance chamber and the perception chamber of the variable valve timing device.

일반적으로, 차량의 엔진 효율을 높이려면 차량의 주행조건에 따라 엔진의 고속회전시와 저속회전시에 각각 밸브 개폐시기를 달리할 필요가 있게 된다.In general, in order to increase the engine efficiency of the vehicle, it is necessary to change the valve opening / closing time at high speed and low speed rotation of the engine according to the driving conditions of the vehicle.

특히, 흡기 밸브 개폐시기는 충진효율에 지대한 영향을 주는 인자로서, 흡기밸브를 일찍 열어주면 밸브 오버랩 기간이 길어져서, 고속에서는 흡,배기 관성유동을 충분히 이용할 수 있으므로 체적효율이 증가하지만, 저속에서는 잔류가스량의 증가로 오히려 체적효율이 떨어지고 HC의 배출량이 증가되는 경향이 된다.In particular, the opening and closing of the intake valve is a factor which greatly affects the filling efficiency. When the intake valve is opened early, the valve overlap period becomes longer, and the volume efficiency increases because the intake and exhaust inertia flow can be sufficiently used at high speed. Increasing the amount of residual gas tends to reduce volumetric efficiency and increase HC emissions.

이러한 문제를 해결하기 위해 흡기 밸브의 개폐시기를 가변시키기 위한 방법으로는 연속가변 밸브 듀레이션 장치(CVVT:Continuously Variable Valve Timing)가 있는데, 연속가변 밸브 듀레이션 장치는 오일펌프와 오일제어밸브(OCV: Oil-Flow Control Valve)와 유압에 의해 흡기 캠샤프트를 위상각을 진각 또는 지각시키기 위한 오일회로로 구성된다.In order to solve this problem, there is a continuously variable valve timing device (CVVT) for changing the opening and closing time of the intake valve. The continuously variable valve duration device is an oil pump and an oil control valve (OCV: Oil). It consists of an oil circuit for advancing or retarding the phase angle of the intake camshaft by the flow control valve and hydraulic pressure.

그 작동관계는 오일제어밸브(OCV)에 의해 오일펌프로부터 공급되는 유압을 연속가변 밸브타이밍 장치의 진각유로 또는 지각유로로 공급함으로써, 흡기 밸브 타이밍을 진각 또는 지각시키는 작용을 하는 것이다.The operation relationship is to act to advance or perceive the intake valve timing by supplying the hydraulic pressure supplied from the oil pump by the oil control valve (OCV) to the advance passage or the perceptual passage of the continuously variable valve timing device.

즉, 엔진의 아이들 상태나 저속회전시에는 상기 오일제어밸브(OCV)에 의해 유압을 진각유로로 공급하여 흡기 밸브의 클로징 타임(closing time)을 진각시키고, 엔진의 고속회전시에는 유압을 지각유로로 공급하여 흡기 밸브의 클로징 타임(closing time)을 지각시킨다.That is, when the engine is idle or at low speed, the oil control valve (OCV) supplies the hydraulic pressure to the advance passage to advance the closing time of the intake valve. To close the closing time of the intake valve.

종래의 가변 밸브 듀레이션 장치는 캠 샤프트와 스프라켓 사이의 각도만을 조정하여 타이밍만을 변화시키도록 작동된다.The conventional variable valve duration device is operated to change only the timing by adjusting only the angle between the cam shaft and the sprocket.

상기와 같이 가변 밸브 타이밍 장치만 적용된 경우에 듀레이션은 고정되어 있으므로 흡기 밸브 타이밍과 필요한 밸브 타이밍 오버랩 구간 설정 사이의 모순이 발생하여 성능 향상에 한계가 있는 문제점이 발생 되었다.When only the variable valve timing device is applied as described above, since the duration is fixed, a contradiction occurs between the intake valve timing and the required valve timing overlapping interval setting, thereby causing a problem in that the performance is limited.

상기 가변 밸브 타이밍 장치와 더불어서 밸브 듀레이션을 변화시키는 가변 밸브 리프트 방식의 경우에는 대부분 유한한 단계(2단 또는 3단)로 작동되도록 구성되며, 연속적인 변화를 갖으며 작동되게 하기 위해서는 설계 단가와 안정적인 품질 확보가 곤란한 문제점이 발생 되었다.In addition to the variable valve timing device, the variable valve lift method that changes the valve duration is configured to operate in a finite stage (two or three stages), and in order to operate with a continuous change, the design cost and stable There was a problem that it was difficult to secure quality.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 차량의 엔진상태 또는 속도에 따라 흡기밸브의 열리는 시간이 가변 가능한 차량용 가변 밸브 듀레이션 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a variable valve duration apparatus for a vehicle in which the opening time of the intake valve is variable according to the engine state or speed of the vehicle.
