Description
본 발명은 배기가스를 이용한 오일팬의 오일 온도조절장치 및 그 방법에 관한 것으로서, 보다 상세하게는 엔진시동 직후에 오일의 성능향상을 위해 배기가스의 일부가 오일팬 측으로 유도되도록 하고, 배기가스의 열과 오일팬 내의 오일이 열교환되도록 하므로서 오일의 온도가 상승되도록 하는 배기가스를 이용한 오일팬의 오일 온도조절장치 및 그 방법에 관한 것이다.The present invention relates to an oil temperature control apparatus and method of an oil pan using exhaust gas, and more particularly, to direct a part of the exhaust gas to the oil pan side to improve the performance of the oil immediately after the engine is started. The present invention relates to an oil temperature regulating apparatus and method of an oil pan using exhaust gas to allow heat and oil in the oil pan to exchange heat.
일반적으로 엔진의 마찰마력은 그 크기가 클수록 엔진의 동력손실을 크게 한다. 특히, 엔진의 냉간시동이나 엔진의 난기운전 조건에서 낮은 오일온도는 엔진의 운동부로 점도가 높은 오일을 공급하게 되므로서 엔진의 마찰마력을 증대시키는 원인이 된다.In general, the larger the frictional horsepower of the engine, the greater the power loss of the engine. In particular, the low oil temperature in the cold start of the engine or the turbulent operation conditions of the engine is to supply a high viscosity oil to the moving part of the engine, thereby increasing the frictional horsepower of the engine.
그래서 엔진을 시동한 직후에 오일의 온도를 상승시키기 위한 장치로서 오일팬 내에 전기로 발열하는 열선히터를 설치므로서 운전 전이나 시동 후에 일정시간동안 오일을 가열하여 오일의 점도가 적정한 수준을 유지하도록 하는 장치가 제공되고 있다.Therefore, as a device for raising the temperature of oil immediately after starting the engine, a heating heater that generates electricity in the oil pan is installed so that the oil viscosity can be maintained at an appropriate level by heating the oil for a predetermined time before or after the operation. An apparatus is provided.
도 3은 종래의 오일팬의 오일 온도조절장치의 구성을 설명하기 위한 도면으로서, 엔진의 하부에 취부되는 오일팬(10)의 내부 일측으로 열선히터(11)가 돌출형성된다. 그리고 운전자가 엔진을 시동하게 되면 열선 스위치가 온(On)되어, 알터네이터의 교류전원이 상기 열선히터(11)에 인가되도록 설정된다. 따라서 오일팬(10) 내의 차가운 오일에 전열이 가해져 온도가 상승되므로서 오일은 저점도의 상태를 유지하게 된다.3 is a view for explaining the configuration of the oil temperature control device of the conventional oil pan, the hot wire heater 11 protrudes to one side of the inner side of the oil pan 10 mounted on the lower part of the engine. When the driver starts the engine, the hot wire switch is turned on so that AC power of the alternator is applied to the hot wire heater 11. Therefore, as the heat is applied to the cold oil in the oil pan 10 and the temperature is increased, the oil maintains the state of low viscosity.
그러나 종래 오일팬의 오일 온도조절장치의 경우에 열선히터에 소요되는 전원을 발생시키기 위해서는 엔진의 보기류 벨트에 의해 구동되는 알터네이터의 용량이 증대되어야 하므로서 차량의 중량이 증가되는 문제점이 있었다. 또한, 차량의 중량이 증가되면 연비개선의 측면에서는 불리하므로서 모든 차량에 적용되지 못하고 엔진시동 후에 급출발이 요구되는 순찰차나 소방차 등의 일부의 차량에서만 엔진의 냉간운전의 무리를 피하기 위해서 장착되고 있는 실정이었다.However, in the case of the oil temperature control device of the conventional oil pan, in order to generate power required for the heating heater, the capacity of the alternator driven by the accessory belt of the engine must be increased, thereby increasing the weight of the vehicle. In addition, when the weight of the vehicle is increased, it is disadvantageous in terms of improving fuel efficiency, and therefore, only some vehicles such as patrol cars or fire trucks, which are not applied to all vehicles and require rapid start after the engine starts, are installed to avoid cold driving of the engine. It was.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위해서 안출된 것으로서, 엔진시동 직후에 오일의 성능향상을 위해 배기가스의 일부가 오일팬 측으로 유도되도록 하고, 배기가스의 열과 오일팬 내의 오일이 열교환되도록 하므로서 오일의 온도가 상승되도록 하는 배기가스를 이용한 오일팬의 오일 온도조절장치 및 그 방법을 제공하는 데 목적이 있다.Therefore, the present invention has been made to solve the above problems, so that a part of the exhaust gas is guided to the oil pan side to improve the performance of the oil immediately after the engine start, so that the heat of the exhaust gas and the oil in the oil pan heat exchange It is an object of the present invention to provide an oil temperature control device for an oil pan using an exhaust gas and a method for allowing the temperature of the oil to rise.

도면 중에 표시되는 도면부호 30은 본 발명에 의한 형성된 오일 히터를 지시하는 것이고, 도면부호 20은 엔진을 지시하는 것이다.Reference numeral 30 indicated in the drawing indicates an oil heater formed according to the present invention, and reference numeral 20 indicates an engine.
엔진(20)은 실린더 블럭(21)과 실린더 헤드(22)로 구성되며, 실린더 블럭(21)의 하부에는 엔진(20)을 윤활 및 냉각하기 위한 오일이 저장되는 오일팬(23)이 취부된다.The engine 20 is composed of a cylinder block 21 and a cylinder head 22, and an oil pan 23 for storing oil for lubricating and cooling the engine 20 is mounted below the cylinder block 21. .
상기한 오일 히터(30)는 엔진(20)의 일측에 마련된 터보차저(25)를 통과한 배기가스 중의 일부를 순환시켜 배기가스의 열이 오일팬(23) 내부로 전열되도록 하므로서 오일이 가열되도록 하기 위한 것이다. 이를 위해, 상기 오일 히터(30)는 금속재의 파이프로써 오일팬(23) 내부에 지그재그 형식으로 배열되고, 그 일측 끝단의 유입파이프(31)는 터보차저(25) 측에 연결되고, 다른 일측 끝단의 유출파이프(32)는 배기파이프(27) 측에 연결된다. 이 때, 오일 히터(30)를 이루는 금속 파이프의 직경은 배기파이프(27) 직경의 1/10 정도인 것이 바람직하다.The oil heater 30 circulates a part of the exhaust gas passing through the turbocharger 25 provided at one side of the engine 20 so that the heat of the exhaust gas is transferred to the inside of the oil pan 23 so that the oil is heated. It is to. To this end, the oil heater 30 is arranged in a zigzag form inside the oil pan 23 as a metal pipe, the inlet pipe 31 of one end thereof is connected to the turbocharger 25 side, the other end The outlet pipe 32 of is connected to the exhaust pipe 27 side. At this time, the diameter of the metal pipe constituting the oil heater 30 is preferably about 1/10 of the diameter of the exhaust pipe 27.
그리고 상기한 오일 히터(30)의 유입파이프(31)가 터보차저(25) 측에서 분지되는 위치에는 배기가스의 흐름방향을 선택적으로 제어하기 위한 밸브(33)가 형성된다. 밸브(33)는 진공펌프(26)의 진공압에 의해서 작동되는 액츄에이터(34)에 의해서 단속되도록 구성되는데, 진공펌프(26)의 진공압이 액츄에이터(34)로 공급되는 것이 제어되도록 상기 진공펌프(26)와 액츄에이터(34) 간에는 솔레노이드 밸브(35)가 장착된다. 참고로 밸브(33)는 버터플라이 타입의 밸브인 것이 바람직하다.And the valve 33 for selectively controlling the flow direction of the exhaust gas is formed at a position where the inlet pipe 31 of the oil heater 30 is branched on the turbocharger 25 side. The valve 33 is configured to be interrupted by an actuator 34 operated by the vacuum pressure of the vacuum pump 26, so that the vacuum pressure of the vacuum pump 26 is controlled to be supplied to the actuator 34. The solenoid valve 35 is mounted between the 26 and the actuator 34. For reference, the valve 33 is preferably a butterfly valve.
솔레노이드 밸브(35)는 배터리(36)의 전원이 공급되는지의 여부에 의해서 그 단속이 이루어지는데, 상기 배터리(36)의 전원과 솔레노이드 밸브(35) 간에는 전원의 흐름을 단속하기 위한 바이메탈 스위치(37)가 마련된다. 바이메탈 스위치(37)는 오일팬(23) 내의 오일의 온도를 측정하기 위한 수단으로서, 오일팬(23) 내의 오일 온도가 일정수준 이하가 되면 배터리(36)의 전원이 연결되도록 하며, 오일의 온도가 일정수준 이상이 되면 배터리(36)의 전원이 끊어지도록 구성되는 것이다. 이 때, 바이메탈 스위치(37)의 작동온도는 80~90℃ 인 것이 바람직하다.The solenoid valve 35 is intermittent depending on whether or not the battery 36 is supplied with power. The bimetal switch 37 for controlling the flow of power between the power source of the battery 36 and the solenoid valve 35 is performed. ) Is provided. The bimetal switch 37 is a means for measuring the temperature of the oil in the oil pan 23. When the oil temperature in the oil pan 23 is below a certain level, the power of the battery 36 is connected, and the oil temperature When the predetermined level or more, the battery 36 is configured to be cut off. At this time, the operating temperature of the bimetal switch 37 is preferably 80 ~ 90 ℃.
이상과 같이 구성되는 본 발명의 작동을 플로우차트와 함께 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above with a flowchart as follows.
운전자가 시동키를 돌려 엔진을 시동하게 되면, 상기한 바이메탈 스위치(37)가 오일팬(23) 내의 오일온도를 측정하게 된다.When the driver starts the engine by turning the ignition key, the bimetal switch 37 measures the oil temperature in the oil pan 23.
엔진(20)의 냉간 시동시에 오일의 온도가 바이메탈 스위치(37)의 설정온도보다 이하인 것으로 측정되면, 바이메탈 스위치(37)가 연결되어 솔레노이드 밸브(35)로 전원이 인가된다. 솔레노이드 밸브(35)에 전원이 인가되어 솔레노이드 밸브(35)가 개방된 상태가 되면, 진공펌프(26)의 진공압이 상기 액츄에이터(34)로 전달되어 버터플라이 타입의 밸브(33)가 개방되도록 제어한다.If the temperature of the oil is measured to be lower than the set temperature of the bimetal switch 37 at the cold start of the engine 20, the bimetal switch 37 is connected to supply power to the solenoid valve 35. When power is applied to the solenoid valve 35 and the solenoid valve 35 is opened, the vacuum pressure of the vacuum pump 26 is transmitted to the actuator 34 to open the butterfly valve 33. To control.
버터 플라이 타입의 밸브(33)가 개방된 상태가 되면, 엔진(20)의 배기 매니폴드(24)와 터보차저(25)를 통과한 고온고압의 배기가스 중의 일부가 상기 오일 히터(30)의 유입파이프(31) 측으로 흐르게 된다.When the butterfly valve 33 is opened, a part of the high temperature and high pressure exhaust gas which has passed through the exhaust manifold 24 and the turbocharger 25 of the engine 20 is transferred to the oil heater 30. It flows to the inflow pipe 31 side.
오일 히터(30) 측으로 유입된 배기가스에 수반된 고열은 오일팬(23)에서 오일의 차가운 열과 열교환되어 오일의 온도를 높인 후, 유출파이프(32)를 통해 배기파이프(27) 측으로 배기된다.The high heat accompanying the exhaust gas introduced into the oil heater 30 is heat-exchanged with the cold heat of the oil in the oil pan 23 to increase the temperature of the oil, and is then exhausted to the exhaust pipe 27 through the outlet pipe 32.
한편, 오일팬(23) 내의 오일온도가 적정수준으로 상승되면, 오일의 온도는 바이메탈 스위치(37)에 감응되고, 배터리(36)의 전원이 솔레노이드 밸브(35)로 인가되는 것을 차단하게 된다. 솔레노이드 밸브(35)가 닫힘상태로 되면 진공펌프(24)의 진공압이 액츄에이터(34)로 전달되는 것이 차단되고, 유입파이프(31)의 입구를 단속하는 밸브(33)가 닫힘상태가 되므로서 배기가스가 오일 히터(30) 측으로 흐르는 것이 차단된다. 따라서 오일팬(23) 내의 오일이 너무 과열되어 오일의 점도가 필요이상으로 낮게 되는 것을 방지하게 된다.On the other hand, when the oil temperature in the oil pan 23 rises to an appropriate level, the temperature of the oil is sensitive to the bimetal switch 37, and the power of the battery 36 is blocked from being applied to the solenoid valve 35. When the solenoid valve 35 is in the closed state, the vacuum pressure of the vacuum pump 24 is blocked from being transmitted to the actuator 34, and the valve 33 for controlling the inlet of the inlet pipe 31 is closed. The exhaust gas is blocked from flowing to the oil heater 30 side. Therefore, the oil in the oil pan 23 is prevented from being overheated so that the viscosity of the oil becomes lower than necessary.
이상과 같이 구성되는 본 발명은 엔진의 냉간시동시에 오일 팬 내의 오일의 온도를 신속히 상승시켜 저점도 오일이 엔진에 공급되도록 하므로서 오일이 엔진의 모든 운동부에 원활하게 공급되어 엔진의 마찰손실마력을 감소시켜 불필요한 동력손실을 저감하게 되는 커다란 장점이 있는 것이다. 또한 엔진의 웜업시간이 단축되며, 시동직후 급출발에 대한 엔진보호 능력이 향상되고, 엔진이 연비가 향상되는 커다란 장점이 있는 것이다.The present invention is configured as described above, so that the oil temperature in the oil pan during the cold start of the engine to quickly increase the low-viscosity oil to be supplied to the engine, the oil is smoothly supplied to all the moving parts of the engine to reduce the friction loss horsepower of the engine There is a huge advantage to reduce unnecessary power loss. In addition, the warm-up time of the engine is shortened, the engine protection against rapid start immediately after starting is improved, and the engine has a great advantage of improving fuel economy.
