이러한 목적을 달성하기 위하여, 본 발명은 실린더 블록 내의 워터자킷 양측에, 워터자킷의 용량을 변화시키는 가동플레이트가 각각 설치되고, 상기 워터자킷내에 수온을 감지하는 수온센서를 설치하며, 상기 가동플레이트는 수온센서에서 감지된 냉각수 온도에 의하여 전자적제어유니트의 제어신호에 따라 작동하는 솔레노이드로 가동될 수 있도록 한 것이다.In order to achieve this object, the present invention is provided on both sides of the water jacket in the cylinder block, movable plates for varying the capacity of the water jacket are respectively installed, and a water temperature sensor for sensing the water temperature in the water jacket, the movable plate is The coolant temperature detected by the water temperature sensor enables the solenoid to operate in accordance with the control signal of the electronic control unit.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제 1 도는 본 발명의 작동에 의하여 워터자킷의 용량이 최소일 때를 나타낸 실린더 블록의 단면도이고,1 is a cross-sectional view of a cylinder block showing when the capacity of the water jacket is minimal by the operation of the present invention,

제 2 도는 본 발명의 작동에 의하여 워터자킷의 용량이 최대일 때를 나타낸 실린더 블록의 단면도이다.2 is a cross-sectional view of a cylinder block showing when the water jacket has a maximum capacity by the operation of the present invention.

본 발명은 실린더 블록(10) 내의 워터자킷(J) 양측에, 워터자킷(J)의 용량을 변화시키는 가동플레이트(100)가 각각 설치되고, 상기 워터자킷(J) 내에 수온을 감지하는 수온센서(200)를 설치하며, 상기 가동플레이트(100)는 수온센서(200)에서 감지된 냉각수 온도에 의하여 전자적제어유니트(300)의 제어신호에 따라 작동하는 솔레노이드(400)로 가동될 수 있도록 한 것이다.In the present invention, the movable plate 100 for varying the capacity of the water jacket J is installed on both sides of the water jacket J in the cylinder block 10, and a water temperature sensor for sensing the water temperature in the water jacket J. And install (200), the movable plate 100 is to be operated by the solenoid 400 that operates in accordance with the control signal of the electronic control unit 300 by the coolant temperature sensed by the water temperature sensor 200. .

미설명 부호 20은 실린더이고, 30은 물펌프이다.Reference numeral 20 is a cylinder and 30 is a water pump.

제 1 도에 도시한 바와같이, 본 발명은 초기 시동순간, 즉 엔진이 냉간상태일 때에는 저온의 냉각수에 의하여 가동플레이트(100)는 커버(120)와 가동플레이트(100) 사이에 설치된 압축 스프링(110)에 의하여 워터자킷(J)의 용량이 최소인 상태로 이동되므로, 이때의 소량의 냉각수는 연료의 연소열에 의하여 온도가 신속하게 상승된다.As shown in FIG. 1, the present invention provides the movable plate 100 with a compression spring provided between the cover 120 and the movable plate 100 by the low temperature coolant when the engine is in an initial startup state, that is, when the engine is cold. Since the capacity of the water jacket J is moved to the minimum state by 110, the temperature of the small amount of coolant is rapidly increased by the heat of combustion of the fuel.

그리고, 제 2 도에 도시한 바와 같이, 엔진이 난기상태일 때에는 고온의 냉각수에 의하여 워터재킷(J) 일측의 전자적제어유니트(300)와 연결된 수온센서(200)의 신호에 따라 전기적으로 연결된 솔레노이드(400)가 가동플레이트(100)를 끌어당기므로 워터자킷(J)의 용량이 최대인 상태가 된다.And, as shown in Figure 2, when the engine is in a turbulent state solenoid electrically connected to the signal of the water temperature sensor 200 connected to the electronic control unit 300 on one side of the water jacket (J) by the high temperature cooling water Since 400 pulls the movable plate 100, the capacity of the water jacket J is at a maximum.

따라서, 자동차의 초기시동시에 실린더 블록(10)의 워터자킷(J)에 있는 냉각수를 최단시간내에 상승시켜 히터코어 등으로 공급하게 된다.Therefore, the cooling water in the water jacket J of the cylinder block 10 is raised in the shortest time and supplied to the heater core etc. at the time of initial start-up of a motor vehicle.

상술한 바와 같이, 본 발명은 초기시동시 냉각수의 온도를 신속하게 상승시켜 워밍업시간을 단축시키므로, 최적의 히터 난방성능과 애미션(EMISSION)안정 및 연비향상의 효과가 있다.As described above, the present invention increases the temperature of the cooling water at initial startup to shorten the warm-up time, and thus has the effect of optimum heater heating performance, stability of Emission and improvement of fuel efficiency.
