본 발명은 자동차 엔진의 윤활장치에 관한 것으로, 더욱 상세히는 엔진의 시동전에 개폐밸브를 조작하여 별도의 오일탱크로부터 엔지내의 크랭크 케이스에 설치된 오일제트로 오일을 공급하여 분사시킴으로써 엔진의 각부에 윤활유가 공급되도록 한 시동전 작동되는 엔진윤활장치에 관한 것이다.The present invention relates to a lubrication device for an automobile engine, and more particularly, by operating an on / off valve before starting the engine, supplying oil to an oil jet installed in a crankcase in an engine from a separate oil tank and injecting oil into each part of the engine. It relates to an engine lubrication device which is operated before starting to supply.

일반적으로 자동차 엔진의 윤활장치는 엔진의 작동을 원활하게 하고, 그 작동이 엔진의 수명을 다할 때까지 오래 유지할 수 있도록 운동마찰부분에 엔진오일을 공급하는 장치로서, 이의 구성은 오일팬, 오일펌프, 오일여과기 및 유압조절기 등으로 구성되어 있다.In general, the lubricator of a car engine is a device that supplies engine oil to the motion friction part so that the operation of the engine is smooth and the operation is long for the life of the engine, and its configuration includes an oil pan and an oil pump. It consists of oil filter and hydraulic regulator.

이를 보다 상세히 설명하면, 먼저 엔지오일을 저장하는 용기인 오일팬은 엔진의 크랭크 케이스 하부에 개스킷에 의하여 빌봉된 상태로 부착되고, 상기 오일 팬의 오일을 빨아올려 엔진의 각 부분에 압송시키는 기구인 오일펌프는 통상 크랭크 샤프트 혹은 캠 사프트에 의해 기어나 체인으로 구동되도록 설치되며, 상기 오일펌프에 의하여 엔진의 각부로 압송되는 오일을 청정하는 역할을 하는 오일여과기 및 상기 오일펌프에서 압송된 오일의 압력을 일정압력으로 조정하는 기능을 갖는 유압조절밸브가 구비되어서 된 것이다.In more detail, first, the oil pan, which is a container for storing the engine oil, is attached to the lower part of the engine crankcase by a gasket, and is a mechanism for sucking up the oil of the oil pan and pumping the oil to each part of the engine. The oil pump is usually installed to be driven by gears or chains by a crankshaft or cam shaft, and the oil filter serving to clean the oil pumped to each part of the engine by the oil pump and the pressure of the oil pumped from the oil pump Hydraulic control valve having a function to adjust the pressure to a constant pressure is provided.

이와 같이 구성된 종래의 자동차 엔진윤활장치에 있어서, 오일팬에 저장되어 있는 오일은 엔진시동시 작동되는 오일펌프에 의해 뿜어올려지고, 뿜어올려진 오일은 오일여과기를 지나면서 청정되며, 청정된 오일은 오일통로를 지나면서 각 메인 베어링, 캠 샤프트 및 커넥팅 로드 등을 윤활하게 되고, 오일통로에서 실린더 헤드로 압송된 오일은 각 밸브개폐기구를 윤활하게 되는 등 오일은 오일펌프에 의해 엔진각부로 압송되어 윤활작용을 하게 되는 것이었다.In the conventional automobile engine lubrication device configured as described above, the oil stored in the oil pan is pumped up by the oil pump operated at engine start, the pumped oil is cleaned through the oil filter, and the purified oil is Each main bearing, camshaft and connecting rod are lubricated while passing through the oil passage, and the oil pumped from the oil passage to the cylinder head lubricates each valve opening and closing mechanism. It was to be lubricated.

한편, 엔진의 각 부분으로 압송되어 스며든 오일은 엔진정지시 모두 엔진의 하부로 흘러내려 오일팬으로 수렴되는데, 상기한 종래의 엔진윤활장치는 그 오일펌프가 엔진의 작동과 연계되어 작동되도록 되어 있었으므로, 자동차가 주차된 상태에서 엔진을 시동하게 되면 엔진 각 동작부에는 충분한 유막이 형성되지 못한 상태에서 엔진이 동작되는 데, 이때 엔진오일이 없는 상태에서 동작되는 피스톤과 실린더 등은 기밀히 유지되지 못하며 마모가 됨으로써 압축압력이 저하되어 엔진의 효율이 떨어지는 문제점이 있었다.On the other hand, the oil that is pumped into each part of the engine flows down to the lower part of the engine when the engine stops and converges to the oil pan. The conventional engine lubrication device is such that the oil pump is operated in conjunction with the operation of the engine. Therefore, when the engine is started while the car is parked, the engine operates without sufficient oil film formed on each engine operation part, and the pistons and cylinders operated without the engine oil are kept confidential. There was a problem in that the compression pressure is lowered and the efficiency of the engine is lowered because it is not worn.

즉, 정차후 엔진시동시 오일통로 및 엔진각부에 엔진오일이 없는 상태에서 엔진이 시동되는 문제점은 자동차의 엔진수명이 단축되는 가장 큰 마모율은 발생시키게 되는 폐단이 있었다.That is, the problem that the engine is started in the absence of engine oil in the oil passage and the engine parts at the time of engine start after the stop has a closed end that causes the largest wear rate shortening the engine life of the car.

본 발명은 상기한 종래의 폐단을 해소하기 위하여 안출된 것으로, 본 발명의 목적은 엔진의 무오일 시동시 발생되는 엔진 각부의 마멸을 최소화할 수 있도록 엔진 시동전에 엔진오일을 미리 엔진각부에 분사시킬 수 있는 수단을 제공하는데 있는 것이다.The present invention has been made to solve the above-mentioned conventional closed end, the object of the present invention is to inject the engine oil to the engine parts before the engine start in advance to minimize the wear of the engine parts generated at the start of the engine oil-free It is to provide a means to do so.

이와 같은 목적으로 차량의 엔진오일이 별도로 저장되는 오일탱크와, 상기 오일탱크의 오일을 크랭크 케이스에 설치된 오일제트로 보내는 유로와, 상기 유로사이에 설치되어 오일탱크의 오일을 공급 및 차단하는 개폐밸브로 구성되고, 상기 오일탱크에 저장되는 엔진오일은 엔진에 설치된 오일펌프의 바이패스통로를 통하여 수시로 공급되도록 한 시동전 작동되는 엔진윤활성장치를 제공한 것으로, 이하, 본 발명의 실시예를 첨부된 도면에 의하여 상세히 설명하기로 한다.For this purpose, the oil tank in which the engine oil of the vehicle is stored separately, the flow path for sending the oil of the oil tank to the oil jet installed in the crankcase, and the opening and closing valve is provided between the flow path to supply and block the oil in the oil tank The engine oil is stored in the oil tank is provided to provide an engine lubrication device that is operated before starting to be supplied from time to time through the bypass passage of the oil pump installed in the engine, hereinafter, attached to the embodiment of the present invention It will be described in detail by the drawings.

제1도는 본 발명의 일 실시예에 의한 시동전 작동되는 엔진윤활장치의 구성을 개략적으로 도시한 것으로, 본 실시예에서는 엔진(1)에 장착되는 오일펌프(10)에는 릴리이프밸브(20)가 설치된 바이패스통로(12)로부터 별도의 오일탱크(30)로 오일 공급로(31)가 연결되고, 이 오일탱트(30)로부터 엔진(1)의 크랭크 케이스(2)에 설치된 오일제트(3)로 오일 배출로(32)가 연결된다.FIG. 1 schematically shows the configuration of an engine lubrication device operated before starting according to an embodiment of the present invention. In this embodiment, the oil pump 10 mounted on the engine 1 includes a relief valve 20. The oil supply passage 31 is connected to the separate oil tank 30 from the bypass passage 12 in which the oil passage 30 is installed, and the oil jet (3) installed in the crank case 2 of the engine 1 from the oil tank 30. ) Is connected to the oil discharge path 32.

상기 오일펌프(10)의 바이패스통로(12)에는 제2도에 도시한 바와 같이 그 상부에 오일탱크(30)로 통하는 오일 공급로(31)가 접속된 제1배출포트(13)가 형성되고, 상기 제1배출포트(13)의 하부에는 제2배출포트(14)가 형성되어 오일펌프(10)의 흡입구(11)로 유로가 형성되며, 이 바이패스통로(12)에는 코일스프링(21)과 이 코일스프링(21)에 의하여 일정한 압력으로 밀림으로써 바이패스통로(12)의 유입구(12a)를 막고 있는 플런저(22)로 구성된 릴리이프밸브(20)가 설치된다. 이 릴리이프밸브(20)는 오일펌프(10) 내의 오일압력이 일정압력 이상으로 상승되게 될 경우 플런저(22)가 오일펌프(10) 내의 오일압력에 의하여 밀리게 되면서 오일펌프(10) 내의 오일이 제1배출포트(13)로 배출되어 오일탱크(30)에 저장되게 되는 것이고, 오일탱크(30)내에 오일이 충분히 공급되고 오일펌프(10) 내의 압력이 상승하게 될 경우에는 상기 플런저(22)가 좀더 후퇴하게 되면서 오일펌프(10) 내의 오일이 제2배출포트(14)를 통하여 오일펌프(10)의 흡입구(11)로 바이패스되도록 구성된 것이다.In the bypass passage 12 of the oil pump 10, as shown in FIG. 2, a first discharge port 13 is connected to an oil supply passage 31 connected to the oil tank 30 at an upper portion thereof. The second discharge port 14 is formed at the lower portion of the first discharge port 13 to form a flow path through the inlet 11 of the oil pump 10. The bypass spring 12 has a coil spring ( The relief valve 20 which consists of 21 and the plunger 22 which blocks the inlet 12a of the bypass passage 12 by pushing by the constant pressure by this coil spring 21 is provided. The relief valve 20 is the oil in the oil pump 10 as the plunger 22 is pushed by the oil pressure in the oil pump 10 when the oil pressure in the oil pump 10 is raised above a certain pressure The plunger 22 is discharged to the first discharge port 13 and stored in the oil tank 30. When the oil is sufficiently supplied into the oil tank 30 and the pressure in the oil pump 10 is increased, the plunger 22 As the retreat more), the oil in the oil pump 10 is configured to be bypassed to the inlet 11 of the oil pump 10 through the second discharge port 14.

한편, 상기 제1배출포트(13)로부터 오일탱크(30)로 연결된 오일 공급로(31)에는 오일탱크(30) 내의 오일이 오일펌프(10)로 역류되는 것을 방지하기 위한 첵밸브(33)가 설치되고, 상기 오일탱크(30)로부터 엔진(1)의 크랭크 케이스(2)에 설치된 오일제트(3)까지 연결된 오일 배출로(32)에는 개폐밸브(34)가 설치되며, 이개폐밸브(34)는 차내의 인스트루먼트 패널등에 설치함으로써 운전자 등이 조작을 용이하게 할 수 있도록 한다.On the other hand, in the oil supply path 31 connected to the oil tank 30 from the first discharge port 13, the check valve 33 for preventing the oil in the oil tank 30 to flow back to the oil pump 10 Is installed, and the oil discharge passage 32 connected to the oil jet 3 installed in the crank case 2 of the engine 1 from the oil tank 30, an on-off valve 34 is installed, the opening and closing valve ( 34) is provided in the instrument panel in the vehicle so that the driver or the like can easily operate.

이와 같이 구성된 본 발명의 엔진윤활장치는 기존의 엔진윤활장치와 병행하여 사용하는 것이며, 자동차의 운행시에는 기존의 엔진윤활장치가 작동되면서 엔진의 각부에 엔진오일이 공급되어 적절한 엔진의 윤활상태를 확보하게 되는 것이며, 이러한 자동차 운행중 오일펌프(10) 내의 압력이 일정압력 이상 상승하게 될 경우에는 바이패스통로(12)에 설치된 릴리이프밸브(20)의 플러저(22)가 상기 오일펌프(10) 내의 오일압에 의하여 코일스프링(21)의 반력을 이겨내면서 밀리게 되어 오일펌프(10) 내의 오일이 바이패스통로(12)의 상부에 형성된 제1배출포트(13)로 배출되어 오일탱크(30) 내에 저장되게 되는 것이다.The engine lubrication device of the present invention configured as described above is used in parallel with the existing engine lubrication device, and during operation of the vehicle, the engine oil is supplied to each part of the engine while the existing engine lubrication device is operated to provide an appropriate lubrication state of the engine. When the pressure in the oil pump 10 rises above a certain pressure during driving of the vehicle, the plunger 22 of the relief valve 20 installed in the bypass passage 12 is the oil pump 10. By overcoming the reaction force of the coil spring (21) by the oil pressure in the oil) the oil in the oil pump 10 is discharged to the first discharge port 13 formed in the upper portion of the bypass passage 12 to the oil tank ( 30) to be stored in.

상기한 오일탱크(30)에는 자동차의 운행도중 여분의 오일압발생에 의하여 오일펌프(10) 내에서 바이패스되는 오일을 수시로 저장하게 되는 것이며, 오이탱크(30) 내에 오일이 일정압력으로 일정량이상 채워지게되면 제1배출포트(13)가 열리게 되더라도 오일펌프(10) 내의 오일이 오일탱크(30)로 공급되지 않게 되는 것이고, 이때 오일 공급로(31)에는 첵밸브(33)가 설치되어 있으므로 오일탱크(30) 내에 저장된 오일은 오일 펌프(10)로 역류되지 않게 되는 것이다.The oil tank 30 is to store the oil which is bypassed in the oil pump 10 due to the occurrence of excess oil pressure during the driving of the vehicle from time to time, the oil in the oil tank 30 at a certain amount of pressure When it is filled, even if the first discharge port 13 is opened, the oil in the oil pump 10 is not supplied to the oil tank 30, and at this time, the oil supply passage 31 is provided with a check valve 33 The oil stored in the oil tank 30 will not be backflowed to the oil pump 10.

이와 같이 오일탱크(30)에 충분히 오일이 채워지게 되고 도 이상 오일이 공급되지 않는 상태에서 오일펌프(10) 내의 압력이 더욱 상승하게 되면 릴리이프밸브(20)의 플런저(22)는 오일펌프(10) 내의 오일압력에 의하여 더욱 밀리게 됨으로써 바이패스통로(12)의 하부에 형성된 제2배출포트(14)를 통하여 오일펌프(10)의 흡입구(11)로 바이패스되게 되는 것이다.As such, when the oil tank 30 is sufficiently filled with oil and the oil is not supplied any more, the pressure in the oil pump 10 increases further, and the plunger 22 of the relief valve 20 is an oil pump ( By being pushed further by the oil pressure in 10, it is bypassed to the inlet 11 of the oil pump 10 through the second discharge port 14 formed in the lower portion of the bypass passage 12.

한편, 차량을 뿡시간 정차한 후 엔진시동을 걸기전에 운전자가 오일펌프(10)로부터 오일제트(3)로 연결된 오일 배출로(32)의 개폐밸브(34)를 수초 정도 열어주게 되면 일정압력으로 저장되어 있던 오일탱크(30) 내의 엔진오일이 오일 배출로(32)를 통하여 오일제트(3)로 공급되어 엔진(1)의 실린더(4) 내벽으로 분사되는 것이며, 이에 의하여 실린더(4)와 피스톤(5) 사이에 유막이 형성되게 되는 것이다.On the other hand, if the driver opens the on / off valve 34 of the oil discharge passage 32 connected to the oil jet 3 from the oil pump 10 before starting the engine after stopping the vehicle for a few hours, the pressure is maintained at a constant pressure. The engine oil stored in the oil tank 30 is supplied to the oil jet 3 through the oil discharge path 32 and sprayed to the inner wall of the cylinder 4 of the engine 1, whereby the cylinder 4 and The oil film is to be formed between the piston (5).

운전자는 상기 개폐밸브(34)를 적당시간 동안 열어주어 오일탱크(30) 내의 오일이 엔진(1)의 실린더(4) 내벽으로 분사되도록 한 후, 개폐밸브(34)를 잠그고 엔진(1)의 시동을 걸게 되면 실린더(4)와 피스톤(5) 사이에 유막이 형성되어 있으므로 엔진(1)의 시동이 원활하고 실린더(4) 내벽의 마모가 줄어들게 되는 것이다.The driver opens the on-off valve 34 for a suitable time so that the oil in the oil tank 30 is injected into the inner wall of the cylinder 4 of the engine 1, and then closes the on-off valve 34 and the engine 1 When starting, since an oil film is formed between the cylinder 4 and the piston 5, the starting of the engine 1 is smooth and the wear of the inner wall of the cylinder 4 is reduced.

이상 설명한 바와 같이 본 발명은 오일펌프 내에서 바이패스되는 엔진 오일의 일부를 별도의 오일탱크 내에 일정압력 이상으로 저장해 두었다가 엔진의 시동을 걸기전에 개폐밸브를 열어 이 오일탱크 내의 오일을 실린더 내벽으로 분사시켜 주도록 한 것으로, 본 발명에 의하면 엔진 시동전에 엔진오일을 미리 엔진 각부에 주입시켜 무오일 시동에 의한 엔진의 마모를 방지할 수 있으며, 이에 따라 엔진의 수명연장은 물론 엔진의 성능을 향상시킬 수 있는 잇점이 있는 것이다.As described above, the present invention stores a part of the engine oil bypassed in the oil pump in a separate oil tank at a predetermined pressure or more, and then opens and closes the valve before starting the engine to inject the oil in the oil tank to the cylinder inner wall. According to the present invention, the engine oil is pre-injected into each part of the engine prior to starting the engine, thereby preventing the engine from being worn due to the start of the engine without oil, thereby extending the life of the engine and improving the performance of the engine. There is an advantage.
