본 발명은 연속가변밸브타이밍 시스템의 오일공급장치에 관한 것으로, 더욱 상세히는 연속가변밸브타이밍 시스템이 적용된 엔진의 실린더헤드에 상기 연소각변밸브타이밍 시스템을 오일을 공급해줄 수 있는 오일공급장치를 설치함에 있어서, 오일공급장치의 구성부품이 설치되는 별도의 보조헤드를 구성하여 상기 실린더헤드에 간단히 결합시킬 수 있도록 구성함에 따라 실린더헤드의 설치면 가공 및 오일공급장치의 설치를 더욱 용이하게 할 수 있으며, 엔진의 전체적인 길이가 연장되는 것을 최소화시켜 엔진룸의 공간활용도를 더욱 향상시킬 수 있도록 한 연속가변밸브타이밍 시스템의 오일공급장치에 관한 것이다.The present invention relates to an oil supply device for a continuously variable valve timing system, and more particularly, to an oil supply device for supplying oil to the combustion angle variable valve timing system in a cylinder head of an engine to which a continuous variable valve timing system is applied. In this case, by configuring a separate auxiliary head to be installed in the component parts of the oil supply device to be easily coupled to the cylinder head, it is possible to facilitate the installation surface processing of the cylinder head and installation of the oil supply device, The present invention relates to an oil supply device of a continuously variable valve timing system that minimizes the overall length of an engine and further improves space utilization of an engine room.

일반적으로 내연기관 엔진은 외부로부터 공기 및 연료를 공급받아 연소실에서 연소시키므로서 동력을 발생시키는 장치로서, 상기 공기 및 연료를 연소실로 흡입하기 위하여 흡기밸브를 구비하고 있으며, 연소실에서 연소된 폭발가스를 배출하기 위하여 배기밸브를 구비하고 있고, 이러한 흡,배기밸브는 크랭크축의 회전에 연동하여 회전하는 캠축의 회전에 의해 개폐되는 것이다.In general, an internal combustion engine engine generates power by receiving air and fuel from the outside and combusting it in a combustion chamber. The engine is provided with an intake valve for inhaling the air and fuel into the combustion chamber. An exhaust valve is provided for discharging, and the intake / exhaust valve is opened and closed by the rotation of the cam shaft which rotates in conjunction with the rotation of the crank shaft.

한편, 엔진의 효율을 높이기 위해서는 차량의 주행조건에 따라 엔진 회전수의 고저나 엔진부하의 고저 등에 따라 밸브의 개폐시키를 달리할 필요가 있다.On the other hand, in order to increase the efficiency of the engine, it is necessary to change the opening and closing of the valve according to the height of the engine speed, the height of the engine load, and the like depending on the running conditions of the vehicle.

특히, 흡기밸브의 개폐시키는 충진효율에 많은 영향을 주게 되는데, 흡기밸브를 미리 열어주게 되면 밸브 오버랩 기간이 길어지게 되면서 고속에서는 흡,배기 관성유동을 충분히 이용할 수 있으므로 체적효율이 증가하지만, 저속에서는 잔류 가스량의 증가로 오히려 체적효율이 떨어지고 HC(탄화수소)의 배출량이 증가하게 되는 것이다.Particularly, the filling efficiency of opening and closing the intake valve has a great effect. If the intake valve is opened in advance, the valve overlap period becomes longer and the volume efficiency increases because the intake and exhaust inertial flow can be sufficiently used at high speed, but at low speed. Increasing the amount of residual gas results in lower volumetric efficiency and increased HC (hydrocarbon) emissions.

따라서 크랭크축의 회전에 따라 캠축의 밸브 오버랩 기간이 정해지지 않고, 설정된 변위를 갖도록 하여 엔진의 구동상황에 따라 적절한 밸브 타이밍을 제어하는 기술이 개발되어 적용되고 있으며, 이를 연속가변밸브타이밍(CVVT : Continuously Variable Valve Timing) 시스템이라고 한다.Therefore, the valve overlap period of the camshaft is not determined according to the rotation of the crankshaft, and the technology to control the proper valve timing according to the driving situation of the engine by having a set displacement has been developed and applied. Valve Timing) system.

즉, 연속가변밸브타이밍 시스템이란 엔진의 회전수 및 차량의 부하 상태에 따라 흡기 및 배기쪽 캠샤프트의 위상을 변화시켜 흡기 및 배기밸브의 개폐 시기를 연속적으로 변경하는 시스템으로서, 다시 말하면 밸브 오버랩을 변화시키는 시스템이며, 그 목적은 배기가스의 저감과 성능의 향상 및 공회전의 안정화를 목적으로 하는 것이다.In other words, the continuous variable valve timing system is a system that continuously changes the opening and closing times of the intake and exhaust valves by changing the phase of the intake and exhaust camshafts according to the engine speed and the vehicle load condition. It is a system for changing, and the purpose is to reduce exhaust gas, improve performance and stabilize idling.

여기서 밸브타이밍이란 흡기밸브와 배기밸브가 열림 또는 닫힘 시기를 말하는데, 흡기과정은 흡기밸브가 열려 닫히기까지의 신기가 들어오는 과정이며, 배기과정은 배기밸브가 열려서 닫힐 때까지의 연소가스 배출과정으로서 이러한 밸브의 여닫는 시기는 엔진의 성능에 영향을 주게 되는 것이다.Here, the valve timing refers to the timing of opening or closing the intake valve and the exhaust valve, and the intake process is a process of entering the fresh air until the intake valve is opened and closed, and the exhaust process is a process of discharging combustion gas until the exhaust valve is opened and closed. The opening and closing time of the valve will affect the performance of the engine.

또한 밸브 오버랩은 흡,배기 밸브가 동시에 열려 있는 구간으로 일반적인 엔진의 경우 한번 밸브오버랩이 설정되면 엔진속도의 전구간 영역에서 일정하게 사용되므로 저속 또는 고속영역에서는 불리한 점이 있다.In addition, the valve overlap is a section in which the intake and exhaust valves are open at the same time. In the case of a general engine, once the valve overlap is set, the valve overlap is uniformly used in the entire range of the engine speed, which is disadvantageous in the low or high speed range.

따라서 밸브 오버랩을 엔진 부하에 맞게 제어한다는 것은 곧 엔진 출력의 향 상으로 나타나며, 이와 같이 엔진 부하에 맞게 제어하는 것이 연속가변밸브타이밍 시스템인 것이다.Therefore, the control of the valve overlap to the engine load is indicated by the improvement of the engine output, and thus the control to the engine load is a continuously variable valve timing system.

그리고 이와 같은 연속가변밸브타이밍 시스템의 구성요소는 연속가변밸브타이밍 유니트와, 오일공급장치인 오일 컨트롤 밸브(OCV : Oil Control Valve)와, 오일 온도 센서(OTS : Oil Temperature Sensor)와, 오일 컨트롤 밸브 필터 및 오일통로, 그리고 오토 텐셔너 등으로 구성되는데, 상기 연속가변밸브타이밍 유니트는 배기쪽 캠샤프트에 장착되며, 내부는 하우징, 로터(Rotor)로 구성되어 있고, 하우징과 로터 베인(Vene) 사이에는 진각실과 지각실이 구성되며, 오일 컨트롤 밸브를 통해 오일이 유입되어 로터 베인이 움직이게 되는 것이다.The components of the continuous variable valve timing system include a continuous variable valve timing unit, an oil supply valve (OCV: oil control valve), an oil temperature sensor (OTS), and an oil control valve. It consists of a filter, an oil passage, and an auto tensioner. The continuously variable valve timing unit is mounted on the exhaust camshaft, and consists of a housing and a rotor, and between the housing and the rotor vane. The chamber and the perception chamber are composed, and oil flows through the oil control valve to move the rotor vane.

또한 오일 컨트롤 밸브는 연속가변밸브타이밍 시스템의 핵심 부품으로 오일펌프로부터 공급된 엔진오일을 엔진 컴퓨터(ECU)의 제어를 받아 연속가변밸브타이밍 유니트로 가는 유체 통로의 방향을 변경시켜 밸브 개폐 시기를 조정하는 역할을 한다.In addition, the oil control valve is a key component of the continuous variable valve timing system. The engine oil supplied from the oil pump is controlled by the engine computer (ECU) to change the direction of the fluid passage to the continuous variable valve timing unit to adjust the timing of opening and closing the valve. It plays a role.

그리고 오일 온도 센서는 연속가변밸브타이밍 유니트의 작동 유체인 엔진오일의 경우 온도에 따라 밀도에 변화가 생기게 되므로 이러한 온도에 따른 변화량을 보상해주는 센서로서, 오일 컨트롤 밸브로 엔진오일이 들어가기 전에 온도를 측정하여 ECU 에 보내고 ECU 는 오일 컨트롤 밸브를 구동하여 보정하게 된다.In addition, the oil temperature sensor is a working fluid of the continuous variable valve timing unit. In this case, the density changes depending on the temperature of the engine oil, which is a fluid that compensates for the change according to the temperature, and measures the temperature before the engine oil enters the oil control valve. The ECU is sent to the ECU for correction by driving the oil control valve.

또한 오일 컨트롤 밸브 필터는 오일 컨트롤 밸브로 가는 엔진오일속의 불순물을 여과시키는 역할을 하게 되며, 오토 텐셔너는 연속가변밸브타이밍 시스템이 설치되는 배기쪽 캠샤프트의 스프로킷과 흡기쪽 캠샤프트의 스프로킷을 서로 연결 해주는 체인의 장력 조절장치로서 상기 오토 텐셔너는 연속가변밸브타이밍 시스템의 응답성 지연 또는 편차 및 기능상의 문제를 방지하여 성능의 안전성을 확보하게 된다.In addition, the oil control valve filter serves to filter impurities in the engine oil to the oil control valve, and the auto tensioner connects the sprocket of the exhaust camshaft and the intake camshaft with the continuous variable valve timing system. As a tension control device of the chain, the auto tensioner ensures the safety of performance by preventing the responsiveness delay or deviation and functional problems of the continuously variable valve timing system.

한편, 이와 같은 연속가변밸브타이밍 시스템은 엔진을 개발할 당시에 적용하는게 엔진의 설계측면에서 여러가지 유리하지만 이미 양산된 엔진에 적용할 수도 있는 것인데, 이와 같이 기존의 엔진에 연속가변밸브타이밍 시스템을 적용하는 경우에는 다음과 같은 문제점이 있었다.On the other hand, the continuous variable valve timing system is advantageous in terms of the design of the engine, but may be applied to the already mass-produced engine, which is applied at the time of engine development. In this case, the continuous variable valve timing system is applied to an existing engine. There were the following problems.

즉, 종래에는 도 1 과 도 2 에 도시한 바와 같이 엔진의 실린더헤드(10)의 일측으로 연속가변밸브타이밍 시스템을 적용함에 있어서, 배기쪽 캠샤프트(30)의 끝단에 연속가변밸브타이밍 유니트(22)가 설치되며, 실린더헤드(10)의 한쪽 설치면은 가공된 상태에서 오일공급장치(21)가 설치되고, 상기 오일공급장치(21)와 연속가변밸브타이밍 유니트(22)는 누유방지를 목적으로 하는 커버(40)에 의해 가려지게 되는 것이다.That is, in the conventional application of the continuous variable valve timing system to one side of the cylinder head 10 of the engine, as shown in FIGS. 1 and 2, the continuous variable valve timing unit is disposed at the end of the exhaust cam shaft 30. 22) is installed, the oil supply device 21 is installed in one of the mounting surface of the cylinder head 10, the oil supply device 21 and the continuous variable valve timing unit 22 to prevent leakage It is to be covered by the cover 40 of the purpose.

그러나 상기와 같이 엔진의 실린더헤드(10)에 연속가변밸트타이밍 유니트(22)와 오일공급장치(21)가 설치될 경우 그 폭이 실린더헤드(10)의 폭에 비하여 커지게 되면서 상기 실린더헤드(10)의 설치면을 가공할때 공구의 출입을 위한 공간의 확보 등으로 인하여 결국 엔진의 전체적인 길이가 필요 이상으로 길어지게 되면서 엔진룸의 타 부품과의 간섭을 일으키게 됨에 따라 타부품의 설계변경 및 기타 추가 설치작업 등이 필요하게 되며, 엔진룸의 공간활용도가 떨어지게 되는 문제점이 있었다.However, when the continuous variable belt timing unit 22 and the oil supply device 21 are installed in the cylinder head 10 of the engine as described above, the width thereof becomes larger than the width of the cylinder head 10 and the cylinder head ( When machining the installation surface of 10), the overall length of the engine becomes longer than necessary due to the securing of space for access of the tool, which causes interference with other parts of the engine room. Other additional installation work is required, and there is a problem that the space utilization of the engine room is reduced.

따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 오일공급장치가 설치된 보조헤드를 개별적으로 제작하여 실린더헤드의 가공된 설치면에 간단히 체결하여 연속가변밸브타이밍 시스템이 구성될 수 있도록 함에 따라 연속가변밸브타이밍 시스템을 적용하면서 오일공급장치에 의해 엔진의 길이가 필요 이상으로 길어지는 것을 방지함과 동시에 오일공급장치의 오일홀 가공시 작업성이 더욱 향상될 수 있는 연속가변밸브타이밍 시스템의 오일공급장치를 제공하는데 있다.Therefore, an object of the present invention is to solve the problems as described above, to make the continuous variable valve timing system by simply fastening to the machined installation surface of the cylinder head by separately manufacturing the auxiliary head is installed oil supply device Therefore, the continuous variable valve timing system is applied to prevent the engine length from being longer than necessary by the oil supply device, and at the same time, the workability of the continuous variable valve timing system can be further improved during the oil hole processing of the oil supply device.
