Description
본 발명은 차량용 에어필터에 관한 것으로, 특히 외부공기를 흡입하는 흡입구의 소정부위에 에어필터와 상기 에어필터에 걸러지는 불순물을 검사하는 칼라감지센서를 구비하여 상기 칼라감지센서에 설정된 값이상의 불순물이 검출되면 제어부에 연결되어 있는 경보표시등이 점등되고 경보음이 발생되어 적절한 에어필터의 교환시기를 알려주는 차량용 에어필터의 오염도 검사장치에 관한 것이다.The present invention relates to an air filter for a vehicle, and in particular, an air filter and a color detecting sensor for inspecting impurities filtered by the air filter are disposed at a predetermined portion of an intake port for injecting external air, so that impurities of more than a value set in the color detecting sensor are removed. When detected, the alarm indicator connected to the control unit is turned on and the alarm sound is generated and the pollution level inspection device for a vehicle air filter to inform the time of replacement of the appropriate air filter.
일반적으로, 공기흡입장치는 엔진에 필요한 공연비를 맞추기 위해 공기를 공급해 주는 장치로써 에어필터, 혜어훌로우메터, 스로틀바디, 서지탱크, 스로틀 포지션 센서, 흡기온 센서, 에어밸브 등으로 이루어져 있다.In general, the air intake device is a device for supplying air to match the air-fuel ratio required for the engine, and consists of an air filter, a heater flow meter, a throttle body, a surge tank, a throttle position sensor, an intake air temperature sensor, and an air valve.
상기 에어필터를 통해 흡입된 공기는 에어훌로우메터에 의해 측정되며 스로틀 바디를 통해 다이나믹 챔버로 들어간 공기는 다이나믹 챔버로부터 흡기매니홀드로 분배되어 여기서 인젝터로부터 연료가 분사되어 혼합된다. 또한 엔진이 냉각되어 있을때는 에어밸브가 열려 공기는 스로틀 밸브를 바이패스하여 다이나믹 챔버로 들어간다. 아이들링시 스로틀 밸브는 거의 닫혀 있고 연소에 필요한 소량의 공기가 스로틀 바디의 바이패스 통로를 통해 공급되어 엔진의 아이들링을 조절한다.The air sucked through the air filter is measured by an air flow meter, and the air entering the dynamic chamber through the throttle body is distributed from the dynamic chamber to the intake manifold where fuel is injected from the injector and mixed. In addition, when the engine is cooled, the air valve opens and air bypasses the throttle valve and enters the dynamic chamber. When idling, the throttle valve is almost closed and a small amount of air for combustion is supplied through the bypass passage of the throttle body to regulate the idling of the engine.
차량의 흡입구를 통해 차량에 흡입된 공기는 차량내에 구비되어 있는 에어필터에 유입되고, 상기 에어필터에 유입된 공기는 에어필터에서 불순물이 걸러져 차량내의 공기가 사용되는 소정부위로 유입된다. 상기 에어필터를 통해 걸러지는 불순물은 에어필터에 부착되고, 상기 에어필터에 부착된 불순물에 의해 에어필터는 조금씩 색상이 변하게 된다. 상기 에어필터는 일정시간 이상 사용하게 되면 에어필터의 본래 기능인 불순물 제거작용을 제대로 하지 못하게 되고, 상기 에어필터를 통과한 불순물이 포함된 공기가 차량의 소정부위에 유입되면, 자동차 고장의 한 원인으로 작용하게 된다. 그러므로 운전자는 상기 에어필터에 불순물이 많이 끼게 되면 새로운 에어필터로 교환해야 한다.Air sucked into the vehicle through the intake port of the vehicle flows into the air filter provided in the vehicle, and the air introduced into the air filter flows into a predetermined portion where air in the vehicle is used by filtering impurities from the air filter. The impurities filtered through the air filter are attached to the air filter, and the color of the air filter is changed little by little by the impurities attached to the air filter. If the air filter is used for a predetermined time, the impurity removal function, which is an original function of the air filter, may not be properly performed. If air containing impurities passing through the air filter enters a predetermined part of the vehicle, it may be a cause of a vehicle failure. It will work. Therefore, the driver should replace the air filter with a new one if the air filter gets a lot of impurities.
종래의 차량용 에어필터의 오염도 검사장치는 제 1도에 도시된 바와 같이 에어필터(1)의 일측에 위치하는 고주파발생부(2)로부터 고주파를 발사하고, 상기 에어필터(1)의 맞은편 일측에 고주파수신부(3)를 구비하여 상기 고주파발생부(2)에서발사된 고주파가 에어필터(1)를 거쳐 고주파수신부(3)에 수신되는 고주파의 투과성을 이용하여 에어필터(1)의 오염도를 검사한다. 상기 고주파 수신부(3)에 수신된 고주파는 제어기(4)로 입력되고, 상기 제어기(4)에서는 미리 설정되어 있는 소정의 값과 고주파수신부(3)에 수신된 값을 비교하여, 상기 수신된 고주파가 설정값보다 작으면 경보음을 울리는 등의 동작을 함으로써 에어필터(1)의 교환시기를 알려준다.The pollution level inspection apparatus of a conventional vehicle air filter emits a high frequency from the high frequency generator 2 located on one side of the air filter 1, as shown in FIG. 1, and the opposite side of the air filter 1. The high frequency receiver 3 is provided at the high frequency emitted by the high frequency generator 2 so that the degree of contamination of the air filter 1 is improved by using the high frequency permeability received by the high frequency receiver 3 through the air filter 1. Check it. The high frequency received by the high frequency receiver 3 is input to the controller 4, and the controller 4 compares a predetermined value with a value received by the high frequency receiver 3 to the received high frequency. Is less than the set value, an alarm sounds or the like to notify the replacement time of the air filter 1.
그러나, 상기 고주파를 이용한 에어필터의 오염도 검사장치는 고주파발생부(2)로 부터 발사된 고주파가 에어필터(1)를 통과할때, 상기 에어필터(1)를 통과하는 공기의 흐름에 지장을 주며, 또한 상기 에어필터(1)를 통과하는 공기흐름에 의해 고주파수신부(3)에 수신되는 고주파가 일정치 않게 되어 에어필터의 정확한 오염도 측정이 어려운 문제점이 있었다.However, when the high frequency emitted from the high frequency generator 2 passes through the air filter 1, the pollution inspection apparatus of the air filter using the high frequency interferes with the flow of air passing through the air filter 1. In addition, the high frequency received by the high frequency receiver 3 is not constant due to the air flow passing through the air filter 1, which makes it difficult to accurately measure the degree of contamination of the air filter.
이에, 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 상기에어필터의 일측에 칼라감지센서를 설치하여 에어필터가 오염됨에 따라 에어필터의 색상이 변하는 성질을 이용하여 에어필터의 오염도를 측정하는 차량용 에어필터의 오염도 검사장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by installing a color detection sensor on one side of the air filter using the property of changing the color of the air filter as the air filter is polluted to determine the pollution degree of the air filter It is an object of the present invention to provide an apparatus for inspecting contamination of a vehicle air filter to be measured.
