Description
본 발명은 엔진오일 온도 조절장치에 관한 것으로, 좀더 상세하게는 엔진오일의 온도에 따라 오일쿨러를 바이패스하는 엔진오일량과 오일쿨러를 통과하는 엔진오일량을 조절하여 엔진오일의 온도를 최적으로 유지하는 엔진오일 온도 조절장치에 관한 것이다.The present invention relates to an engine oil temperature control device, and more particularly, by adjusting the amount of engine oil bypassing the oil cooler and the amount of engine oil passing through the oil cooler according to the temperature of the engine oil. An engine oil temperature control device is provided.
일반적으로, 엔진오일의 온도에 관계없이 항시 오일쿨러를 통해 엔진오일이 흐르게 되면 겨울철 냉시동시나 저속 냉간 운행시 과도한 엔진오일의 냉각으로 인해 마찰 손실이 증가할 뿐만 아니라 적정 오일온도 까지 상승하는데 걸리는 시간이 증가하게 된다.In general, if the engine oil flows through the oil cooler at all times regardless of the engine oil temperature, the time required to rise to the proper oil temperature as well as the friction loss increases due to excessive engine oil cooling during cold start-up or low speed cold operation in winter. Will increase.
따라서, 종래에는 바이패스 통로를 이용하여 엔진오일이 오일쿨러를 통과하지 않도록 바이패스시키는 방법이 사용되고 있는데, 이러한 방법도 엔진온도와 무관하게 고정된 엔진오일량만을 바이패스시켜서 단순히 냉간 시동시의 적정 오일온도 상승시간을 줄이는 것으로, 변화하는 운전조건에 적절한 온도로 엔진오일의 온도를 조절하기가 어려운 문제점이 있었다. Therefore, the conventional method of bypassing the engine oil does not pass through the oil cooler using a bypass passage has been used. This method also bypasses only a fixed amount of engine oil regardless of engine temperature and is simply appropriate for cold start. By reducing the oil temperature rise time, there was a problem that it is difficult to control the temperature of the engine oil to a temperature suitable for changing operating conditions.
이에, 본 발명은 상기한 바와 같은 종래의 제 문제점을 해소하기 위해 안출된 것으로, 엔진오일의 온도에 따라 오일쿨러를 통과하지 않고 바이패스하는 엔진오일량과 오일쿨러를 통과하는 엔진오일량을 조절하여 엔진오일의 온도를 최적으로 유지함으로써, 엔진의 내구성 및 엔진오일의 수명을 향상시킬 수 있는 엔진오일 온도 조절장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, according to the temperature of the engine oil to adjust the amount of engine oil to bypass and the amount of engine oil passing through the oil cooler without passing through the oil cooler. Therefore, the object of the present invention is to provide an engine oil temperature control device capable of improving the engine oil temperature and durability of the engine oil by optimally maintaining the temperature of the engine oil.

상기 도 1에 도시된 바와 같이, 오일펌프(10)로부터 공급되는 엔진오일은 유량조절밸브(20)의 작동 상태에 따라 오일쿨러(30)와 오일필터(40)를 차례로 통과하여 엔진으로 순환되거나, 바이패스 통로(50)와 오일필터(40)를 차례로 통과하여 엔진으로 순환되도록 되어 있다.As shown in FIG. 1, the engine oil supplied from the oil pump 10 is circulated to the engine by sequentially passing through the oil cooler 30 and the oil filter 40 according to the operation state of the flow control valve 20. In order to circulate through the bypass passage 50 and the oil filter 40 in order to the engine.
이때, 상기 유량조절밸브(20)는 전자제어유니트(60)의 제어에 따라 상기 오일펌프(10)에서 공급되는 엔진오일을 상기 바이패스 통로(50) 및/또는 오일쿨러(30)로 적절히 분배하도록 되어 있다.At this time, the flow control valve 20 properly distributes the engine oil supplied from the oil pump 10 to the bypass passage 50 and / or the oil cooler 30 under the control of the electronic control unit 60. It is supposed to be.
그리고, 상기 전자제어유니트(60)는 상기 오일필터(40)에 설치되어 상기 오일필터(40)를 통과하는 엔진오일의 온도를 감지하도록 되어 있는 엔진오일 온도센서(70)에 의해 감지된 엔진오일의 온도에 따라 엔진오일량을 상기 바이패스 통로(50) 및/또는 오일쿨러(30)로 적절히 분배시키도록 상기 유량조절밸브(20)를 제어하는 것으로, 상기 엔진오일 온도센서(70)에 의해 감지된 엔진오일의 온도에 반비례하여 상기 바이패스 통로(50)로 공급되는 엔진오일량을 증가시키고, 상기 엔진오일의 온도에 비례하여 상기 오일쿨러(30)로 공급되는 엔진오일량을 증가시키도록 상기 유량조절밸브(20)를 제어한다.In addition, the electronic control unit 60 is installed in the oil filter 40, the engine oil detected by the engine oil temperature sensor 70 is configured to detect the temperature of the engine oil passing through the oil filter 40 By controlling the flow rate control valve 20 to properly distribute the engine oil amount to the bypass passage 50 and / or the oil cooler 30 according to the temperature of the engine oil temperature sensor 70. To increase the amount of engine oil supplied to the bypass passage 50 in inverse proportion to the sensed engine oil temperature, and to increase the amount of engine oil supplied to the oil cooler 30 in proportion to the temperature of the engine oil. The flow control valve 20 is controlled.
상기와 같이 구성된 본 발명에 따른 엔진오일 온도 조절장치의 작용 및 효과를 좀더 상세히 설명하면 다음과 같다.Referring to the operation and effects of the engine oil temperature control device according to the present invention configured as described above in more detail.
전자제어유니트(60)는 온도센서(70)에 의해 감지된 엔진오일의 온도에 따라 유량조절밸브(20)를 제어하여 오일펌프(10)에서 바이패스 통로(50)를 통해 오일필터(40)로 순환되는 엔진오일량과 오일펌프(10)에서 오일쿨러(30)를 통해 오일필터(40)로 순환되는 엔진오일량을 조절한다.The electronic control unit 60 controls the flow control valve 20 in accordance with the temperature of the engine oil detected by the temperature sensor 70 to the oil filter 40 through the bypass passage 50 in the oil pump 10. The amount of engine oil circulated to and the amount of engine oil circulated to the oil filter 40 through the oil cooler 30 in the oil pump 10 are adjusted.
즉, 전자제어유니트(60)는 온도센서(70)에 의해 감지된 엔진오일의 온도가 미리 설정되어 있는 최대 기준치 이상이면 오일쿨러(30)를 통해서만 오일필터(40)로 엔진오일이 순환되도록 유량조절밸브(20)를 제어하고, 이에 따라 유량조절밸브(20)가 오일펌프(10)로부터 공급되는 엔진오일을 오일쿨러(30)를 통해서만 오일필터(40)로 순환시킨다.That is, the electronic control unit 60 flows so that the engine oil is circulated to the oil filter 40 only through the oil cooler 30 when the temperature of the engine oil detected by the temperature sensor 70 is greater than or equal to a predetermined maximum reference value. The control valve 20 is controlled, whereby the flow control valve 20 circulates the engine oil supplied from the oil pump 10 to the oil filter 40 only through the oil cooler 30.
또한, 온도센서(70)에 의해 감지된 엔진오일의 온도가 미리 설정되어 있는 최소 기준치 이하이면 전자제어유니트(60)가 바이패스 통로(50)를 통해서만 오일필터(40)로 엔진오일이 순환되도록 유량조절밸브(20)를 제어하고, 이에 따라 유량조절밸브(20)가 오일펌프(10)로부터 공급되는 엔진오일을 바이패스 통로(50)를 통해서만 오일필터(40)로 순환시킨다.In addition, when the temperature of the engine oil detected by the temperature sensor 70 is less than the predetermined minimum reference value, the electronic control unit 60 so that the engine oil is circulated to the oil filter 40 only through the bypass passage 50. The flow rate control valve 20 is controlled, whereby the flow rate control valve 20 circulates the engine oil supplied from the oil pump 10 to the oil filter 40 only through the bypass passage 50.
또, 온도센서(70)에 의해 감지된 엔진오일의 온도가 미리 설정되어 있는 최소 기준치 보다 크고 미리 설정되어 있는 최대 기준치 보다 작으면, 전자제어유니트(60)가 엔진오일의 온도에 따라 바이패스 통로(50)를 통해서 오일필터(40)로 순환되는 엔진오일량과 오일쿨러(30)를 통해서 오일필터(40)로 순환되는 엔진오일량을 적절히 조절 분배하도록 유량조절밸브(20)를 제어하고, 이에 따라 유량조절밸브(20)가 오일펌프(10)로부터 공급되는 엔진오일을 바이패스 통로(50)와 오일쿨러(30)를 통해 오일필터(40)로 순환되도록 적절히 분배한다. In addition, when the temperature of the engine oil detected by the temperature sensor 70 is larger than the preset minimum reference value and smaller than the preset maximum reference value, the electronic control unit 60 passes the bypass passage according to the temperature of the engine oil. The flow rate control valve 20 is controlled to properly adjust and distribute the amount of engine oil circulated to the oil filter 40 and the amount of engine oil circulated to the oil filter 40 through the oil cooler 30 through 50. Accordingly, the flow rate control valve 20 properly distributes the engine oil supplied from the oil pump 10 to be circulated to the oil filter 40 through the bypass passage 50 and the oil cooler 30.
이상에서 설명한 바와 같이 본 발명에 따르면, 엔진오일의 온도에 따라 오일쿨러를 통과하지 않고 바이패스하는 엔진오일량과 오일쿨러를 통과하는 엔진오일량을 조절하여 엔진오일의 온도를 최적으로 유지함으로써, 엔진의 내구성 및 엔진오일의 수명을 향상시킬 수 있다. As described above, according to the present invention, by adjusting the amount of engine oil bypassed without passing through the oil cooler and the amount of engine oil passing through the oil cooler according to the temperature of the engine oil, by maintaining the temperature of the engine oil optimally, The durability of the engine and the life of the engine oil can be improved.
