Description
본 발명은 자동차용 엔진의 냉각 장치에 관한 것으로, 보다 구체적으로는 냉각수의 온도에 따라 냉각수 펌프의 작동을 제어하는 자동차용 엔진의 냉각수 펌프 제어 장치에 관한 것이다.The present invention relates to a cooling apparatus for an automotive engine, and more particularly to a cooling water pump control apparatus for an automotive engine for controlling the operation of the cooling water pump according to the temperature of the cooling water.
엔진의 과열을 방지하기 위한 엔진의 냉각 장치에는 수냉식과 공냉식이 있으며, 자동차용 엔진에서는 주로 수냉식이 많이 사용된다. 수냉식 냉각 장치는 실린더와 연소실을 둘러싸는 물 재킷, 냉각수를 실린더 내로 압송 순환시키는 냉각수 펌프, 온도가 높은 냉각수의 열을 외기에 전달하여 냉각하는 라디에이터, 라디에이터의 통풍을 돕는 냉각 팬 등으로 구성되어 있다. 이와 같은 수냉식 냉각 장치는 냉각수 펌프에 의해 순환되는 냉각수가 물 재킷에서 실린더와 연소실의 열을 흡수하여 데워지고, 라디에이터에서 외기와의 열교환에 의해 온도가 저하되는 것에 의해 엔진을 냉각시키게 된다.The cooling device of the engine to prevent the engine overheating is water-cooled and air-cooled, the car engine is mainly used for water cooling. The water-cooled cooling system consists of a water jacket surrounding the cylinder and the combustion chamber, a coolant pump for pumping and circulating the coolant into the cylinder, a radiator for transferring the heat of the coolant to the outside and cooling it to the outside, and a cooling fan for ventilation of the radiator. . Such a water-cooled cooling device cools the engine by cooling the water circulated by the cooling water pump by absorbing heat from the cylinder and the combustion chamber in the water jacket, and lowering the temperature by heat exchange with the outside air in the radiator.
여기서, 냉각수를 순환시키는 냉각수 펌프는 원심 펌프가 사용되며, 벨트에 의해 크랭크 축과 연결되어 있어 크랭크 축의 회전에 의해 작동된다.Here, the cooling water pump for circulating the cooling water is a centrifugal pump is used, is connected to the crank shaft by a belt is operated by the rotation of the crank shaft.
그런데, 엔진의 과열 뿐 아니라 과도한 냉각도 출력, 연비의 악화 및 실린더의 저온 마멸과 같은 현상을 발생시키기 때문에 냉각수의 온도가 절절한 수준으로 유지되는 것이 매우 중요하다. 그러나, 종래에는 냉각수를 순환시키는 냉각수 펌프가 엔진의 크랭크 축에 연결되어 엔진과 동시에 작동되기 때문에, 엔진의 초기 시동시 냉각수의 온도가 낮음에도 불구하고 냉각수 펌프가 작동되어 냉각수를 순환시킴으로써 엔진이 과도하게 냉각되어 상기와 같이 출력과 연비가 악화되고 불완전 연소에 의해 배기 가스 중에 HC, CO와 같은 유해 성분이 많이 발생되는 단점이 있었다.However, it is very important that the temperature of the coolant is maintained at an appropriate level because not only the engine overheating but also excessive cooling causes phenomena such as power output, fuel economy deterioration and low temperature wear of the cylinder. However, conventionally, since the coolant pump for circulating the coolant is connected to the crankshaft of the engine and operated simultaneously with the engine, the coolant pump operates and circulates the coolant even though the temperature of the coolant is low at the initial start-up of the engine. Cooling is deteriorated as described above, the output and fuel economy is deteriorated, there is a disadvantage that a lot of harmful components such as HC, CO generated in the exhaust gas by incomplete combustion.
따라서, 본 발명은 상기와 같은 단점을 해소하기 위해 안출된 것으로, 냉각수의 온도에 따라 냉각수 펌프의 작동을 제어함으로써, 엔진의 초기 시동시 낮은 냉각수 온도에 따른 엔진의 출력 및 연비 악화와 불완전 연소에 의한 배기 가스 중의 HC, CO의 발생을 방지할 수 있도록 된 자동차용 엔진의 냉각수 펌프 제어 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above disadvantages, by controlling the operation of the coolant pump in accordance with the temperature of the coolant, thereby reducing the power output and fuel economy of the engine according to the low coolant temperature at the initial start-up of the engine and incomplete combustion SUMMARY OF THE INVENTION An object of the present invention is to provide a cooling water pump control apparatus for an automotive engine that can prevent generation of HC and CO in exhaust gas.

[실시예]EXAMPLE
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 일 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 냉각수 펌프 제어 장치는 전자식 클러치와, 냉각수 온도 센서, 및 전자 제어 유닛으로 구성된다.The cooling water pump control device according to the present invention is composed of an electronic clutch, a cooling water temperature sensor, and an electronic control unit.
전자식 클러치는 공지의 것으로서, 도 1에 도시된 바와 같은 구조를 가지며, 도 2에 도시된 바와 같이 냉각수 펌프의 펌프 몸체(1)와 펌프 풀리(2) 사이에 설치된다. 즉, 피동 부재(11)는 냉각수 펌프의 축(3)에 축(3)과 함께 회전되도록 고정, 지지되며, 구동 부재(12)는 펌프 풀리(2)와 함께 회전되도록 펌프 풀리(2)에 고정된다.The electronic clutch is known and has a structure as shown in FIG. 1 and is installed between the pump body 1 and the pump pulley 2 of the coolant pump as shown in FIG. That is, the driven member 11 is fixed and supported on the shaft 3 of the cooling water pump so as to rotate together with the shaft 3, and the driving member 12 is connected to the pump pulley 2 so as to rotate together with the pump pulley 2. It is fixed.
펌프 풀리(2)는 벨트(미도시)를 통해 크랭크 축 풀리와 연결되어 있으며, 베어링(4)을 통해 냉각수 펌프의 축(3) 상에 회전가능하게 지지된다. 이와 같은 전자식 클러치(10)는 코일(13)에 전류가 인가되지 않은 상태에서는 구동 부재(12)와 피동 부재(11)가 함께 회전되며, 구동 부재(12)로부터 피동 부재(11)로 회전력이 전달된다. 그러나, 코일(13)에 전류가 인가되면, 코일(13)이 전자석의 역할을 하여 피동 부재(11)가 클러치 스테이터(14)에 고정되고, 구동 부재(12)만 회전되어 구동 부재(12)로부터피동 부재(11)로의 동력 전달은 차단된다.The pump pulley 2 is connected to the crankshaft pulley via a belt (not shown) and is rotatably supported on the shaft 3 of the coolant pump via the bearing 4. In the electronic clutch 10, the driving member 12 and the driven member 11 are rotated together in a state where a current is not applied to the coil 13, and a rotational force is applied from the driving member 12 to the driven member 11. Delivered. However, when a current is applied to the coil 13, the coil 13 serves as an electromagnet so that the driven member 11 is fixed to the clutch stator 14, and only the driving member 12 is rotated to drive the driving member 12. Power transmission from the driven member 11 is interrupted.
그리고, 냉각수 온도 센서(미도시)는 엔진의 냉각수 통로 일측에 설치되어 냉각수의 온도를 감지하여 전자 제어 유닛(미도시)으로 입력한다. 전자 제어 유닛은 또한 전자식 클러치와 연결되어 있으며, 냉각수 온도 센서에서 감지된 냉각수의 온도를 미리 저장된 기준 온도와 비교하여 냉각수의 온도가 기준 온도보다 높은 경우에만 전자식 클러치(10)의 코일(13)에 전류를 인가하고, 그렇지 않은 경우에는 전류를 인가하지 않는다.In addition, the coolant temperature sensor (not shown) is installed at one side of the coolant passage of the engine to sense the temperature of the coolant and input it to the electronic control unit (not shown). The electronic control unit is also connected to the electronic clutch and compares the temperature of the coolant detected by the coolant temperature sensor with a pre-stored reference temperature to the coil 13 of the electronic clutch 10 only when the temperature of the coolant is higher than the reference temperature. A current is applied, otherwise no current is applied.
상기와 같은 구성을 가지는 본 발명에 따른 자동차용 엔진의 냉각수 펌프 제어 장치의 작동에 대하여 설명하면 다음과 같다.Referring to the operation of the coolant pump control apparatus for an automotive engine according to the present invention having the configuration as described above is as follows.
우선, 엔진의 초기 시동시 냉각수의 온도는 전자 제어 유닛에 저장된 기준 온도보다 낮은 상태이다. 따라서, 전자 제어 유닛은 전자식 클러치(10)에 전류를 인가한다.First, the temperature of the coolant at the initial start of the engine is lower than the reference temperature stored in the electronic control unit. Thus, the electronic control unit applies a current to the electronic clutch 10.
따라서, 전자식 클러치(10)의 구동 부재(11)는 클러치 스테이터(14)에 고정되어 회전되지 않으며, 구동 부재(12)의 회전력은 피동 부재(11)로 전달되지 않아 냉각수는 순환되지 않는다. 엔진이 계속 구동되어 냉각수의 온도가 전자 제어 유닛의 기준 온도 이상 올라가면, 전자 제어 유닛은 전자식 클러치(10)에 인가되던 전류를 차단한다. 이에 따라 전자식 클러치(10)의 피동 부재(11)는 클러치 스테이터(14)로부터 떨어져 구동 부재(12)를 따라 회전된다. 따라서, 구동 부재(12)의 회전력이 피동 부재(11)를 통해 펌프 축(3)으로 전달되어 냉각수는 순환된다.Therefore, the drive member 11 of the electronic clutch 10 is fixed to the clutch stator 14 and does not rotate, and the rotational force of the drive member 12 is not transmitted to the driven member 11, so that the coolant is not circulated. When the engine continues to be driven and the temperature of the coolant rises above the reference temperature of the electronic control unit, the electronic control unit cuts off the current applied to the electronic clutch 10. Accordingly, the driven member 11 of the electromagnetic clutch 10 is rotated along the drive member 12 away from the clutch stator 14. Thus, the rotational force of the drive member 12 is transmitted to the pump shaft 3 via the driven member 11 so that the coolant is circulated.
상기된 바와 같은 본 발명은, 냉각수 펌프와 펌프 풀리 사이에 전자식 클러치가 설치되어 냉각수의 온도가 낮은 경우 핌프 풀리로부터 펌프 축으로의 동력 전달을 차단하여 냉각수가 순환되지 않도록 하므로, 엔진의 초기 시동시 낮은 냉각수온도에 따른 엔진의 과도한 냉각으로 인한 엔진의 출력 및 연비 악화가 방지되고, 완전 연소가 촉진되어 배기 가스 중의 HC, CO 등 유해 성분이 저감되는 장점이 있다.As described above, the present invention provides an electronic clutch installed between the coolant pump and the pump pulley to block power transmission from the pimp pulley to the pump shaft when the temperature of the coolant is low, thereby preventing the coolant from being circulated. Engine deterioration and fuel economy deterioration due to excessive cooling of the engine due to the low coolant temperature is prevented, and complete combustion is promoted to reduce harmful components such as HC and CO in the exhaust gas.
