Description
본 고안은 터보 과급 엔진의 급기냉각을 위한 급기 냉각장치에 관한 것으로서, 특히 엔진 냉각수에 의하여 과급된 공기의 온도를 낮추어 엔진의 출력을 증가시키는 터보 과급 엔진의 급기 냉각장치에 관한 것이다.The present invention relates to an air supply cooler for air supply cooling of a turbocharged engine, and more particularly, to an air supply cooler of a turbocharged engine which increases the output of the engine by lowering the temperature of air charged by the engine coolant.
일반적으로 엔진의 출력은 흡입공기의 양에 의해 큰 영향을 받으며, 흡입공기의 양을 증가시키기 위해 배기가스의 폐열을 활용하여 터어빈을 구동시키고, 이 터어빈과 연결된 압축기에 의해 흡입공기를 압축 공급하는 터보 과급방식이 엔진출력 상승의 수단으로서 이미 널리 알려져 활용되고 있다.In general, the output of the engine is greatly affected by the amount of intake air, and in order to increase the amount of intake air, the turbine is driven by utilizing waste heat of exhaust gas, and the inlet air is compressed and supplied by a compressor connected to the turbine. Turbocharge is already widely known and utilized as a means of increasing engine power.
이렇게 압축된 공기는 흡입공기량을 증가시키는 효과가 있지만, 공기압축식 공기의 온도 상승이 수반되어 온도가 높아질수록 공기 밀도가 저하되므로 출력을 상승시키는데는 한계가 있었다. 따라서 과급된 공기를 냉각시키기 위한 여러가지 장치가 고안되어 사용되기에 이르렀으나, 급기 냉각기의 압축공기 냉각효과가 불충분하거나 그 구성이 아주 복잡한 단점이 있었다.The compressed air has an effect of increasing the amount of intake air, but accompanied by an increase in the temperature of the air-compressed air, the air density decreases as the temperature increases, thereby limiting the output. Therefore, various devices for cooling the supercharged air have been devised and used, but the compressed air cooling effect of the air supply cooler is insufficient or its configuration is very complicated.
즉, 종래의 냉각수에 의한 급기 냉각장치를 예를 들어 설명하면 제1도에 도시한 바와 같이 엔진냉각수 냉각장치는 냉각수를 강제로 순환시켜주는 냉각수 펌프(1), 냉각수 방열기(4)안의 가열된 냉각수를 찬 공기를 강제로 통과시켜 냉각시켜주는 냉각팬(2), 냉각수 온도조절을 위한 써모스타트(3), 가열된 냉각수를 공기에 의해 식혀주는 냉각수 방열기(4), 냉각수가 가열되기 전에 냉각수 방열기(4)를 거치지 않고 직접 냉각수 펌프(1)로 보내주는 바이패스호스(11) 등과 각각의 부품을 연결해주는 호스류(5,9,10,15)들로 구성되는데, 급기 냉각기(7)가 충분한 급기 냉각효과를 얻기 위해서는 급기 냉각기(7)를 위한 별도의 냉각수장치와 냉각수 펌프가 소요되어 장치가 복잡해지며, 엔진냉각수를 사용하는 경우는 엔진에 의해 가열된 냉각수를 사용하므로 제3도에서 보는 바와 같이 엔진 부하가 클때에는 급기온도가 엔진냉각수의 온도보다 높아 급기냉각에 효과가 있으나, 부하가 작을 때에는 급기온도가 엔진냉각수의 온도보다 낮아 급기온도가 오히려 상승하여 냉각효과가 없거나 경우에 따라 오히려 과급기를 가열시켜 엔진성능이 저하되는 문제점이 있었다.That is, a conventional air supply cooling device using cooling water will be described, for example. As shown in FIG. 1, the engine cooling water cooling device is heated in the cooling water pump 1 and the cooling water radiator 4 to circulate the cooling water forcibly. Cooling fan (2) for forced cooling of the coolant through the cold air, thermostat (3) for controlling the coolant temperature, coolant radiator (4) for cooling the coolant by air, coolant before the coolant is heated It consists of a bypass hose (11) that sends directly to the coolant pump (1) without passing through the radiator (4) and hoses (5, 9, 10, 15) connecting the respective parts, the air supply cooler (7) In order to obtain a sufficient air supply cooling effect, a separate cooling water device and a cooling water pump are required for the air supply cooler (7), and the device is complicated. When using the engine coolant, the cooling water heated by the engine is used. As shown, when the engine load is large, the air supply temperature is higher than the engine coolant temperature, so it is effective in cooling the air supply. However, when the load is small, the air supply temperature is lower than the engine coolant temperature, so the air supply temperature rises, and thus there is no cooling effect. Rather, there was a problem that the engine performance is lowered by heating the supercharger.
따라서 본 고안은 이상과 같은 문제점을 해결하기 위해 창안된 것으로, 본 고안의 목적은 종래의 급기 냉각장치가 특정 사용조건에서만 급기냉각 효과가 있는데 비해 여러 사용조건에서 고온의 과급 공기를 충분히 식혀 냉각된 과급 공기를 공급하여 엔진 성능을 향상시킴을 그 목적으로 한다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is that the conventional air supply cooling device is cooled by cooling the high-temperature supercharged air sufficiently in various use conditions in comparison with the air supply cooling effect only under specific use conditions. The purpose is to improve the engine performance by supplying the charge air.
상기 목적을 달성하기 위해 본 고안은 엔진의 냉각을 위한 냉각시스템에서 급기 냉각기에서 냉각수 펌프와 연결된 냉각수 호스와, 방열기로부터의 냉각된 냉각수를 보내는 냉각수 호스로 연결된 냉각수 호스를 갖는 터보 과급 엔진의 급기 냉각장치에 있어서, 상기 방열기로부터의 냉각수 호스와 급기 냉각기 사이에 연결된 냉각수 호스에 제어부의 신호 출력에 따라 개폐되는 솔레노이드 밸브를 부설해서 된 것을 특징으로 한다.In order to achieve the above object, the present invention provides an air supply cooling of a turbocharged engine having a coolant hose connected to a coolant pump in an air supply cooler in a cooling system for cooling the engine, and a coolant hose connected to a coolant hose that sends cooled coolant from a radiator. In the apparatus, the solenoid valve which opens and closes according to the signal output of a control part is provided in the coolant hose connected between the coolant hose from the said radiator, and the air supply cooler.

이하에서 본 고안을 바람직한 실시예의 첨부된 도면에 의해 보다 상세히 설명하면 다음과 같다.Hereinafter will be described in more detail by the accompanying drawings of the present invention a preferred embodiment as follows.
본 고안에서 종래와 동일 또는 동등한 부분은 같은 부호로 표기하여 설명하기로 한다.In the present invention, the same or equivalent parts as in the prior art will be described with the same reference numerals.
엔진을 냉각시키고 가열된 냉각수가 써모스타트(3)에 의해 바이패스 호스(11) 또는 방열기(4)로 보내어 냉각시킨 냉각수를 냉각수 펌프(1)로 재순환시키는 엔진의 냉각수 순환 시스템에서 압축 저장된 저온의 공기를 엔진에 유입시키기 위한 급기 냉각기(7)로 냉각수를 보내는 냉각수 호스(15)와, 사용된 냉각수를 다시 냉각수 호스(5)로 환송시켜 냉각수 펌프로 환송시키도록 한 것에 있어서, 냉각수 호스(5)에 엔진 부하의 크고 작음에 따른 제어부의 신호출력에 의해 개폐되는 솔레노이드 밸브(6)를 설치하여 구성된다. 이때 제어부의 신호출력은 흡기매니폴드로부터의 압력센서와 타이밍 기어에서의 속도센서 및 냉각수 온도센서 등에 의해 장치되어 출력되게 할 수 있을 것이다.In the coolant circulation system of the engine where the engine is cooled and the heated coolant is sent to the bypass hose 11 or the radiator 4 by the thermostat 3 to recycle the coolant to the coolant pump 1. The coolant hose (15) for sending coolant to the air supply cooler (7) for introducing air into the engine, and the used coolant is returned to the coolant hose (5) to be returned to the coolant pump (5). ) Is provided by installing a solenoid valve (6) that is opened and closed by the signal output of the control unit according to the large and small of the engine load. At this time, the signal output of the controller may be installed by the pressure sensor from the intake manifold, the speed sensor in the timing gear, and the coolant temperature sensor.
이상과 같이 구성된 본 고안의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
냉각수 펌프(1)에 의해 냉각수 호스(15)로 유입되는 냉각수는 급기냉각기(7)에서 압축 저장된 공기를 냉각시키고 냉각수 호스(5)를 통해 다시 냉각수 호스(10)와 연결되어 냉각시킨 상태에서 냉각수 펌프(1)로 유입 순환된다. 이때 엔진의 부하가 클 때에는 급기온도가 엔진냉각수 온도보다 높기 때문에 솔레노이드 밸브(6)를 열어 급기 냉각기(7)에 냉각수를 공급하고 엔진 부하가 작을 때 급기온도가 엔진 냉각수 온도보다 낮아 급기온도가 오히려 상승하여 냉각효과가 없거나, 경우에 따라 오히려 과급기를 가열시켜 엔진 성능이 저하되기 때문에 이때에는 솔레노이드밸브(6)를 닫아 그 효율성을 제고한다.The coolant flowing into the coolant hose 15 by the coolant pump 1 cools the compressed air stored in the air supply cooler 7 and is connected to the coolant hose 10 again through the coolant hose 5 to cool the coolant. Inlet circulation to the pump (1). At this time, when the load of the engine is large, since the air supply temperature is higher than the engine coolant temperature, the solenoid valve 6 is opened to supply the coolant to the air supply cooler 7, and when the engine load is low, the air supply temperature is lower than the engine coolant temperature. Since there is no cooling effect to rise, or if the engine performance is lowered by heating the supercharger in some cases, at this time, the solenoid valve 6 is closed to improve its efficiency.
따라서 과급 공기 온도를 주어진 조건에서 가능한 한 낮추고 온도가 낮아진 만큼 공기 밀도가 증가되어 제기능을 발휘하는 것이다.Therefore, as much as possible under the given conditions, the charge air temperature is increased, and as the temperature is lowered, the air density is increased to function.
이상과 같이 구성되고 작용되는 본 고안은 급기 냉각기를 냉각하기 위한 냉각수 호스에 설정된 조건에 따라 제어부의 신호에 의해 개폐되는 솔레노이드 밸브를 설치함으로서 각각의 사용조건에서 과급 공기의 냉각효과를 최대로 발휘케 하여 엔진의 출력이 향상되고, 또한 유해 배기가스는 감소하는 효과를 얻을 수 있게 된다.The present invention is constructed and operated as described above to maximize the cooling effect of the charge air in each use condition by installing a solenoid valve that is opened and closed by the signal of the control unit according to the conditions set in the coolant hose for cooling the air supply cooler. Therefore, the output of the engine is improved, and the harmful exhaust gas can be obtained.
