Description
본 고안은 냉각수온 조절장치에 관한 것이다.The present invention relates to a cooling water temperature control device.
엔진 시동 후에는 신속하게 냉각수를 적정온도(80℃전후)까지 높이고 또한 장시간의 내리막길 운행등에서는 엔진이 과냉되는 것을 방지할 필요가 있다. 이 때문에 도3에 도시하는 것과 같이 서모스텟(1)을 장치하고 있다.After starting the engine, it is necessary to rapidly increase the coolant to an appropriate temperature (around 80 ° C) and to prevent the engine from being overcooled for a long downhill run. For this reason, the thermostat 1 is provided as shown in FIG.
서모스탯은 수온에 따라 자동적으로 작동하는 밸브로 실린더 헤드의 라디에이터의 냉각수로 출구에 설치되어 냉각수의 온도가 낮을 때는 밸브가 닫히고 냉각수가 라디에이터로 들어가지 않도록 하여 워터재킷내의 수온을 상승시킨다.The thermostat is a valve that operates automatically according to the water temperature. It is installed at the outlet of the coolant of the radiator of the cylinder head. When the coolant temperature is low, the valve closes and prevents the coolant from entering the radiator to raise the water temperature in the water jacket.
다음에 냉각수온이 일정온도(70∼80℃)이상으로 상승하면 밸브는 서서히 열리고 냉각수가 라디에이터 측으로 유입되어 방열 냉각된 후 엔진으로 순환되게 된다. 그러나 서모스탯은 냉각수온에 의하여 펠릿속에 밀봉된 왁스가 열팽창을 하므로써 밸브가 개폐되는 방식이서 밸브의 개폐가 냉각수온이라는 한가지 인자에만 결정되기 때문에 다양한 운전조건을 반영하지 못하여 중저속 운전시 토오크 확보 및 연비개선이 어렵다는 문제점이 있다.Next, when the temperature of the cooling water rises above a predetermined temperature (70 to 80 ° C.), the valve is gradually opened and the cooling water flows into the radiator, radiates and cools, and then circulates to the engine. However, the thermostat is a method in which the wax sealed in the pellet by the cooling water temperature is opened and closed, and the valve is opened and closed. Therefore, since the opening and closing of the valve is determined only by one factor, the cooling water temperature, it is impossible to reflect various operating conditions. Fuel economy is difficult to improve.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 엔진의 중저속 운전시 토오크를 확보하고 연비를 개선할 수 있는 수온 조절장치를 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its object is to provide a water temperature control device which can secure torque and improve fuel efficiency during medium and low speed operation of an engine.

도 2는 본 고안의 동작 흐름도이다.2 is an operation flowchart of the present invention.
도면 중 부호 1은 워터재킷내의 냉각수온을 검출하는 수온센서이며 부호 2는 스로틀 밸브의 개도량을 검출하는 TPS 센서(Thorttle position sensor)이다. 그리고 부호 3은 엔진의 회전수를 검출하기 위한 rpm센서이며, 부호 4는 실린더헤드의 라디에이터의 냉각수로 출구, 즉 종전의 서모스탯이 설치되는 지점에 설치되어 온-오프 작동되는 솔레노이드 밸브로써 전원 인가시에는 라디에이터측을 개방하여 냉각수가 방열·냉각 되도록 하며, 전원 오프시에는 라디에이터측을 차단하고 워터펌프를 통해 실린더블록의 워터재킷으로 즉시 순환시켜 냉각수온을 상승시키게 된다.In the drawing, reference numeral 1 denotes a water temperature sensor for detecting a cooling water temperature in the water jacket, and reference numeral 2 denotes a TPS sensor (Thorttle position sensor) for detecting an opening amount of a throttle valve. In addition, reference numeral 3 denotes an rpm sensor for detecting an engine speed, and reference numeral 4 denotes a coolant of a radiator of a cylinder head, and is supplied with a solenoid valve that is installed at an outlet, that is, a point where a conventional thermostat is installed, and is operated on and off. When the radiator is opened, the coolant is radiated and cooled, and when the power is turned off, the radiator is blocked and immediately circulated through the water pump to the water jacket of the cylinder block to increase the coolant temperature.
상기 각 센서(1)(2)(3)로부터 검출된 정보는 전자제어장치(5)에 인가 되어 전자제어장치(5)는 이들 정보를 기초로 하여 상기 솔레노이드 밸브(4)를 온-오프 제어한다.The information detected from each of the sensors (1) (2) (3) is applied to the electronic controller (5) so that the electronic controller (5) controls the solenoid valve (4) on-off based on these information. do.
이를 도 2의 동작 흐름도에 의해 설명한다.This is explained by the operation flowchart of FIG. 2.
엔진이 가동되면 냉각수온센서(1)로부터 검출되는 냉각수온이 기준치, 예를 들면 냉각수의 적정온도인 80℃와 비교하여 그보다 낮으면 전자제어장치(5)는 솔레노이드 밸브(4)의 전원을 차단하여 냉각수가 라디에이터를 거치지 아니하고 즉시 엔진으로 유입하도록 하며 냉각수온이 기준치 보다 높으면 솔레노이드 밸브(4)를 온 작동시켜 냉각수가 라디에이터 측으로 흐르도록 한다(도 2(가)). 상기 냉각수온과는 별개로 TPS센서(2)로부터 검출된 스로틀 밸브의 개도 변화량의 일정치 이하, 즉 개도변화량이 작다는 것은 급가속이나 고부하 운전 조건이 아니므로 연손실을 줄이기 위하여 솔레노이드 밸브(4)를 오프 시키고 반대로 기준치 이상이면 솔레노이드 밸브(4)를 온 제어한다(도2(나)).If the coolant temperature detected by the coolant temperature sensor 1 is lower than the reference value, for example, 80 ° C, which is the proper temperature of the coolant when the engine is running, the electronic controller 5 shuts off the power supply of the solenoid valve 4. Thus, the coolant does not go through the radiator immediately into the engine, and if the coolant temperature is higher than the reference value, the solenoid valve 4 is turned on to allow the coolant to flow to the radiator side (Fig. 2 (a)). Apart from the cooling water temperature, since the opening degree change amount of the throttle valve detected from the TPS sensor 2 is lower than a certain value, that is, the opening change amount is not a rapid acceleration or high load operating condition, the solenoid valve 4 ) Is turned off and the solenoid valve 4 is turned on if it is equal to or larger than the reference value (Fig. 2 (b)).
상기 솔레노이드 밸브(4)가 온-오프 작동 되는 또다른 요인으로는 rpm센서(3)로부터 검출된 엔진 회전수가 설정치(중저속 운전을 기준점으로 함) 이상일 때에는 엔진이 고속 운전중임을 말하는 것이므로 이때는 엔진이 과열 되는 것을 방지하기 위하여 솔레노이드 밸브(4)를 온 작동 시키며 엔진 회전수가 기준치 이하, 즉 중저속 운전 조건일 때에는 엔진이 과냉되는 것을 피하기 위하여 솔레노이드 밸브(4)를 오프시켜 냉각수온을 높이게 되는 것이다(도2(다)).Another factor in which the solenoid valve 4 is turned on and off is that the engine is running at high speed when the engine speed detected from the rpm sensor 3 is higher than a set value (medium-low speed operation as a reference point). In order to prevent overheating, the solenoid valve 4 is turned on, and when the engine speed is lower than the reference value, that is, at a low and low speed operating condition, the solenoid valve 4 is turned off to increase the cooling water temperature to avoid overcooling of the engine. (FIG. 2 (c)).
이 밖에도 전자제어장치는 냉각수온에 따른 맵핑값(Mapping Value)의 변화량도 감안하여 솔레노이드 밸브를 온-오프제어 할 수도 있다.In addition, the electronic controller may control the solenoid valve on-off in consideration of the amount of change in the mapping value according to the cooling water temperature.
이상과 같은 본 고안에 의하면 냉각수온뿐 아니라 엔진의 운전조건, 즉 엔진의 회전수 및 스로틀 밸브 개도정보에 따라 엔진이 중저속 운전시에는 냉각 수온을 높게 유지시키도록 작동되는 솔레노이드 밸브를 종래의 단순 온도 감응식 서모스탯에 대체하여 설치하므로써 중저속 운전에서의 토오크 확보 및 연비를 개선할 수 있게 된다.According to the present invention as described above, a conventional solenoid valve that operates to maintain a high cooling water temperature when the engine is operated at a low speed according to not only cooling water temperature but also engine operating conditions, that is, engine rotation speed and throttle valve opening information. By installing in place of the temperature-sensitive thermostat, it is possible to improve torque and fuel economy in low and medium speed operation.
