Description
본 고안은 디젤엔진의 구동시 엔진에서 발생되는 열을 냉각시켜 주는 디젤엔진의 냉각시스템에 관한 것으로써, 좀더 구체적으로는 초기 엔진의 시동시 냉각수라인으로 순환되는 냉각수의 이동을 한시적으로 제어하여 연소실 및 실린더 헤드의 냉각수온도를 빠른 시간내에 상승시킬 수 있도록 한 냉각수순환 제어장치에 관한 것이다.The present invention relates to a cooling system of a diesel engine that cools heat generated from an engine when the diesel engine is driven. More specifically, the combustion chamber is controlled by temporarily controlling the movement of the cooling water circulated to the cooling water line during initial engine start-up. And a cooling water circulation control device capable of raising the cooling water temperature of the cylinder head in a short time.
일반적으로 자동차와 같은 내연기관에서는 실린더의 내부를 피스턴이 고속으로 왕복운동하면서 운동에너지를 얻기 때문에 장시간 운전시 연소실 및 실린더 헤드에 온도가 상승되어 내구성 저하 및 성능저하를 초래하게 되므로 이들을 냉각시켜 주기 위한 냉각시스템을 구비하게 된다.In general, internal combustion engines such as automobiles obtain kinetic energy by reciprocating the inside of cylinders at high speed, so that the temperature rises in the combustion chamber and cylinder head during long periods of operation, resulting in deterioration of durability and deterioration of performance. It will have a cooling system.
도 1은 냉각수를 순환시키는 워터펌프가 설치된 상태의 사시도로써, 하우징(1)내에 회전가능하게 설치된 원심펌프식 워터펌프(2)는 크랭크축(도시는 생략함)에 고정된 폴리에 의해 V-벨트로서 구동되면서 냉각수라인을 통해 냉각수를 실린더 블럭과 라디에이터사이를 반복적으로 순환시키게 된다.1 is a perspective view of a state in which a water pump for circulating cooling water is installed, in which a centrifugal pump type water pump 2 rotatably installed in the housing 1 is formed by a pulley fixed to a crankshaft (not shown). Driven as a belt, the coolant is circulated repeatedly between the cylinder block and the radiator through the coolant line.
즉, 엔진의 구동에 따라 실린더 헤드(도시는 생략함)에서 과열된 냉각수가 라디에이터로 이동되어 냉각팬의 회전에 따른 강제 냉각 및 대기와의 열교환으로 자연 냉각된 다음 써모스태트를 거쳐 다시 실린더 헤드측으로 순환된다.That is, as the engine is driven, the superheated coolant from the cylinder head (not shown) is moved to the radiator, naturally cooled by forced cooling due to the rotation of the cooling fan and heat exchange with the atmosphere, and then through the thermostat to the cylinder head side again. Circulated.
이때 상기 써모스태트는 냉각수라인으로 이동하는 냉각수의 온도에 따라 체적이 변화되면서 냉각수라인의 열림량을 조절하여 라디에이터와 워터펌프(2)로 흐르는 냉각수의 양을 조절하게 되므로 냉각수의 온도를 적절하게 유지시키는 역할을 한다.At this time, the thermostat maintains the temperature of the cooling water properly by adjusting the amount of cooling water flowing to the radiator and the water pump (2) by adjusting the opening amount of the cooling water line by changing the volume according to the temperature of the cooling water moving to the cooling water line. It plays a role.
상기 써모스태트에 설치된 지글밸브(3)는 도 3a와 같이 정상적인 상태에서는 하사점에 위치되어 있어 엔진내의 공기가 지글밸브(3)와 브리더 홀(4)사이의 간극을 통해 라디에이터로 유입되므로 냉각수의 공급을 쉽게 한다.The jiggle valve (3) installed in the thermostat is located at the bottom dead center in the normal state as shown in Figure 3a so that the air in the engine flows into the radiator through the gap between the jiggle valve (3) and the breather hole (4) of the cooling water Make supply easy
그러나 이러한 종래의 냉각수 순환장치는 엔진이 초기 시동시부터 워터펌프(2)에 의해 냉각수를 냉각수 순환경로로 계속해서 순환시키도록 되어 있어 연소실의 주위 온도가 상승될 때까지 오랜시간이 걸리게 되었으므로 특히, 겨울철과 같이 대기온도가 낮을 경우에는 시동후 워밍 업(warm up)에 따른 시간이 오래 걸리게 되었음은 물론 미스 화염(Miss fire) 및 화이트 스모그(white smoke)현상이 많이 발생되는 문제점이 있었다.However, such a conventional coolant circulator has been designed to continuously circulate the coolant in the coolant circulation path by the water pump 2 since the engine is initially started, and thus it takes a long time until the ambient temperature of the combustion chamber is raised. When the air temperature is low, such as in winter, it takes a long time due to warm up after starting, and there is a problem that a lot of miss fire and white smoke occur.
본 고안은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로써, 실린더 블럭내부에서 유동하는 냉각수의 흐름을 일시적으로 차단하여 미스 화염을 줄임과 동시에 화이트 스모크(white smoke)현상도 줄일 수 있도록 하는데 그 목적이 있다.The present invention has been devised to solve such a problem in the related art, and temporarily blocks the flow of the coolant flowing in the cylinder block to reduce the miss flame and reduce the white smoke phenomenon. There is a purpose.
상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 써모스태트 하우징과 라디에이터사이에 연결된 냉각수라인에 콜드스타트 스위치 온시 냉각수라인을 폐쇄하는 마그네틱 밸브를 설치하고 콜드스타트 스위치와 마그네틱 밸브사이에 연결된 신호선에는 냉각수의 온도를 감지하는 온도센서를 연결하여 상기 온도센서가 설정된 온도를 감지함에 따라 마그네틱 밸브가 자동으로 오프되어 냉각수라인을 개방하도록 됨을 특징으로 하는 디젤엔진의 냉각수순환 제어장치가 제공된다.According to a form of the present invention for achieving the above object, a magnetic valve is installed in the cooling water line connected between the thermostat housing and the radiator to close the cooling water line when the cold start switch on, and the cooling water is connected to the signal line connected between the cold start switch and the magnetic valve. By connecting a temperature sensor that detects the temperature of the magnetic sensor is automatically turned off as the temperature sensor detects the set temperature to open the cooling water line is provided with a cooling water circulation control device of the diesel engine.

이하, 본 고안을 일 실시예로 도시한 첨부된 도 2를 참고로 하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying Figure 2 shows an embodiment of the present invention in more detail as follows.
도 2는 본 고안의 구성을 나타낸 사시도로써, 본 고안은 써모스태트 하우징(5)과 라디에이터(6)사이에 연결된 냉각수라인(7)에 콜드스타트 스위치(8)가 초기 온(on)될 때 냉각수라인(7)을 폐쇄하는 마그네틱 밸브(9)가 설치되어 있고 상기 콜드스타트 스위치(8)와 마그네틱 밸브(9)사이에 연결된 신호선(11)에는 냉각수의 온도를 감지하여 냉각수의 온도가 설정된 온도 이상일 때 냉각수라인(7)을 폐쇄하고 있던 마그네틱 밸브(9)를 오프(off)시켜 냉각수라인(7)을 개방하는 온도센서(10)가 연결되어 있다.2 is a perspective view showing the configuration of the present invention, the present invention is the coolant when the cold start switch 8 is initially turned on in the coolant line 7 connected between the thermostat housing 5 and the radiator 6 A magnetic valve 9 is provided to close the line 7, and the signal line 11 connected between the cold start switch 8 and the magnetic valve 9 senses the temperature of the coolant so that the temperature of the coolant is greater than or equal to the set temperature. The temperature sensor 10 which opens the cooling water line 7 by turning off the magnetic valve 9 which closed the cooling water line 7 at the time is connected.
이때, 상기 온도센서(10)는 냉각수의 온도가 80℃이상 됨을 감지함에 따라 마그네틱 밸브(9)를 자동으로 오프시키도록 셋팅되어 있다. 이는, 냉각수의 온도가 80℃이상으로 가열되면 실린더 헤드(도시는 생략함)의 주위온도가 충분히 가열되기 때문이다.At this time, the temperature sensor 10 is set to automatically turn off the magnetic valve 9 in response to detecting that the temperature of the cooling water is more than 80 ℃. This is because the ambient temperature of the cylinder head (not shown) is sufficiently heated when the temperature of the cooling water is heated above 80 ° C.
이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
먼저, 대형 디젤엔진에서 콜드스타트 스위치(8)가 오프된 상태에서는 마그네틱 밸브(9)에 전원이 인가되지 않은 상태이므로 써모스태트 하우징(5)과 라디에이터(6)사이의 냉각수라인(7)에 설치된 상기 마그네틱 밸브(9)가 오프된 상태이다.First, since the power is not applied to the magnetic valve 9 when the cold start switch 8 is turned off in a large diesel engine, the cooling water line 7 between the thermostat housing 5 and the radiator 6 is installed. The magnetic valve 9 is in an off state.
이러한 상태에서 콜드스타트 스위치(8)를 온(on)시키면 상기 마그네틱 밸브(9)가 온되어 냉각수라인(7)을 폐쇄시켜 엔진의 구동으로 워터펌프가 구동하더라도 냉각수가 냉각수라인(7)을 통해 라디에이터(6)로 공급되지 않게 되므로 실린더 헤드내에 잔류하는 냉각수의 온도가 빠른 시간내에 상승된다.In this state, when the cold start switch 8 is turned on, the magnetic valve 9 is turned on to close the cooling water line 7 so that the cooling water is driven by the engine even though the water pump is driven. Since it is not supplied to the radiator 6, the temperature of the cooling water remaining in the cylinder head rises quickly.
이와 같이 실린더 헤드내의 냉각수온도가 상승되어 신호선(11)에 연결된 온도센서(10)가 냉각수의 수온이 80℃이상됨을 감지하면 상기 온도센서가 마그네틱 밸브(9)를 오프시켜 폐쇄되었던 냉각수라인(7)을 개방하게 되므로 가열된 냉각수가 종래의 장치와 마찬가지로 라디에이터(6)를 거치면서 냉각되어 실린더 헤드의 내부로 재유입된다.As such, when the temperature of the coolant in the cylinder head rises and the temperature sensor 10 connected to the signal line 11 detects that the coolant water temperature is 80 ° C. or higher, the temperature sensor turns off the magnetic valve 9 to close the coolant line 7. ), The heated cooling water is cooled while passing through the radiator 6 as in the conventional apparatus, and re-introduced into the cylinder head.
이상에서와 같이 본 고안은 디젤 엔진의 초기 시동시 냉각수라인을 일시적으로 폐쇄하여 실린더 헤드를 빠른 시간내에 적절한 온도가 되게 유지하므로 미스화염이 발생되는 현상을 줄이게 됨은 물론 초기 시동에 따른 화이트 스모크현상 또한 줄이게 되는 효과를 얻게 된다.As described above, the present invention temporarily closes the coolant line during the initial start-up of the diesel engine to maintain the cylinder head at an appropriate temperature in a short time, thereby reducing the occurrence of miss flames and of course, white smoke phenomenon according to the initial start-up. The effect is to reduce it.
