Description
본 고안은 엔진의 냉각 시동시 냉각수의 조기 고온화에 의한 워밍업 촉진장치에 관한 것이다.The present invention relates to a warm-up promoting device by premature high temperature of the coolant at the start of the engine cold start.
실린더내에서 연소된 연소가스의 온도는 2000℃ 이상에 달하므로 엔진이 과열되는 것을 방지하기 위하여 도 3에 도시하는 것과 같이 냉각수를 순환시켜 냉각하는 수냉식 냉각장치가 주로 사용되고 있다.Since the temperature of the combustion gas burned in the cylinder reaches 2000 ° C. or more, a water-cooled cooling device that circulates and cools the cooling water as shown in FIG. 3 is mainly used to prevent the engine from overheating.
상기 수냉식 냉각장치는 실린더(20)와 연소실(21)을 둘러싸는 워터재킷(22), 냉각수를 실린더(20)내로 압송 순환하는 워터펌프(23), 온도가 높아진 냉각수의 열을 외기에 전달하여 냉각하는 라디에이터(24), 라디에이터(24)의 통풍을 돕는 팬(25), 및 시동직후 냉각수를 빨리 적정온도로 올리기 위한 서모스탯(26)으로 구성된다.The water-cooled cooling device is a water jacket 22 surrounding the cylinder 20 and the combustion chamber 21, a water pump 23 for circulating the cooling water into the cylinder 20, and transfers the heat of the cooling water of high temperature to the outside Radiator 24 to cool, a fan 25 to help the ventilation of the radiator 24, and a thermostat 26 for quickly raising the coolant to a proper temperature immediately after starting.
그리고 상기한 냉각시스템은 엔진의 냉간시동시 엔진을 정상 온도로 빨리 높이기 위해 서모스탯(26)을 사용하여 순환되는 냉각수량과 경로의 단축을 꾀함으로써 엔진의 워밍업 시간을 단축하고 있으나 그럼에도 불구하고 엔진의 워밍업 시간이 통상 5분 정도로 길어 그 시간 동안 배기가스 방출량 증대에 따른 환경오염을 피할 수 없다는 문제점을 안고 있다.In addition, the cooling system reduces the warm-up time of the engine by shortening the amount of cooling water circulated by using the thermostat 26 and the path to quickly raise the engine to the normal temperature during cold start of the engine. The warm-up time is usually about 5 minutes, which causes a problem that environmental pollution due to an increase in exhaust gas emissions is inevitable.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 배기가스열을 이용하여 엔진의 냉간시동시 신속히 냉각수의 온도를 정상화 시킴으로써 워밍업 시간을 단축시켜 배기가스 배출을 저감하게 되는 엔진의 워밍업 촉진장치를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its object is to reduce the warm-up time by reducing the exhaust gas emission by shortening the warm-up time by quickly normalizing the temperature of the coolant during cold start of the engine using exhaust gas heat. It is to provide a warm-up accelerator.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1은 본 고안에 의한 엔진의 워밍업 촉진장치를 나타내는 도면이며 도 2는 열교환 하우징의 A-A 단면도이다.1 is a view showing a warm-up accelerator of the engine according to the present invention, Figure 2 is a cross-sectional view of the heat exchange housing A-A.
도면중 부호 1은 워터펌프로서 라디에이터측에 유입된 냉각수를 펌핑하여 냉각수통로(2)를 통해 실린더블록의 워터재킷으로 송출한다.Reference numeral 1 in the figure pumps the coolant flowing into the radiator side as a water pump and sends it to the water jacket of the cylinder block through the coolant passage 2.
상기 냉각수통로(2)(4)의 도중에는 열교환 하우징(3)이 마련되고 그 열교환 하우징(3)을 배기가스 순환통로(4)가 관통하여 지나가며 상기 배기가스 순환통로(5)의 일단은 배기매니폴드(6)에 접속되고 그의 타단은 촉매변환기(7) 전방의 배기파이프(8)에 접속된다.A heat exchange housing 3 is provided in the middle of the cooling water passages 2 and 4, and the exhaust gas circulation passage 4 passes through the heat exchange housing 3, and one end of the exhaust gas circulation passage 5 is exhausted. It is connected to the manifold 6 and its other end is connected to the exhaust pipe 8 in front of the catalytic converter 7.
그리고 상기 열교환 하우징(3)내를 지나는 배기가스 순환통로(5)의 외표면에는 방열용파이프(9)가 방사상으로 복수개가 돌출하여 있으며 배기매니폴드(6)측 접속부 가까이에는 상기 순환통로(5)를 개폐하기 위한 솔레노이드밸브(10)가 설치되어 있다.On the outer surface of the exhaust gas circulation passage 5 passing through the heat exchange housing 3, a plurality of heat dissipation pipes 9 radially protrude, and the circulation passage 5 is located near the exhaust manifold 6 side connection portion. ) Is provided with a solenoid valve (10) for opening and closing.
상기 솔레노이드밸브(10)는 전자제어장치(11)에 의해 개폐 작동이 제어된다.The solenoid valve 10 is controlled to open and close by the electronic control device (11).
이와 같은 본 고안은 엔진이 시동된 후 냉각수온센서(12)로부터 검출되는 냉각수의 온도가 정상치보다 낮을 때에는 이 온도 정보를 받아 전자제어장치(11)가 솔레노이드밸브(10)를 개방되도록 제어한다.The present invention as described above, when the temperature of the coolant detected from the coolant temperature sensor 12 is lower than the normal value after the engine is started, receives the temperature information and controls the electronic controller 11 to open the solenoid valve 10.
솔레노이드밸브(10)가 개방되면 배기매니폴드(6)를 통해 배출되는 배기가스의 일부가 배기가스 순환통로(5)를 통하여 배출하게 되며 도중에 열교환 하우징(3)을 통과하면서 복수개의 방열용파이프(9)에 미치게 되어 고온의 배기가스와 워터펌프(1)로부터 냉각수통로(2)를 통해 열교환 하우징(3)내로 유입되는 냉각수와의 사이에 활발한 열교환이 일어나게 된다.When the solenoid valve 10 is opened, a part of the exhaust gas discharged through the exhaust manifold 6 is discharged through the exhaust gas circulation passage 5, and a plurality of heat dissipation pipes ( 9), active heat exchange occurs between the hot exhaust gas and the coolant flowing from the water pump 1 into the heat exchange housing 3 through the coolant passage 2.
이에 따라 열교환 하우징(3)내로 통과하는 냉각수는 온도가 상승되어 실린더 내로 유입되며 배기가스의 온도는 낮아진 채 배기파이프(8)로 복귀한 후 촉매변환기(7)를 거쳐 정화처리되어 배출되어지게 된다.Accordingly, the coolant passing through the heat exchange housing 3 is introduced into the cylinder at an elevated temperature. The exhaust gas is returned to the exhaust pipe 8 while the temperature of the exhaust gas is lowered, and then purified and discharged through the catalytic converter 7. .
이상과 같은 본 고안에 의하면 배기가스열을 이용하여 엔진의 냉간시동시 냉각수를 가열하여 공급함으로써 엔진의 워밍업 시간을 단축하여 조기에 정상화시키게 되어 배기가스 배출량을 저감하고 배기가스 온도가 낮아져 배기소음이 감소되고 정화효율이 향상되는 효과가 있다.According to the present invention as described above, by using the exhaust gas heat to supply the cooling water during cold start of the engine to shorten the warm-up time of the engine to normalize early to reduce the exhaust gas emissions and lower the exhaust gas temperature to reduce the exhaust noise It is reduced and the purification efficiency is improved.
