Description
본 발명은 자동차용 흡기계통의 카본 흡착 방지장치에 관한 것으로서, 더욱 상세하게는 엔진의 흡기계통에 연소시 흡착되는 카본을 엔진부압과 전기를 이용하야 연소시킨 다음, 다시 흡기계통으로 복귀시킴으로써, 흡기계통에 카본이 흡착되는 것을 방지할 수 있도록 한 자동차용 흡기계통의 카본 흡착 방지장치에 관한 것이다.The present invention relates to an apparatus for preventing carbon adsorption of an intake cylinder for a vehicle. More particularly, the carbon adsorbed upon combustion in an intake cylinder of an engine is burned only by using engine negative pressure and electricity, and then returned to the intake cylinder again. The present invention relates to a carbon adsorption preventing device of an intake box for automobiles which can prevent carbon from being adsorbed on a system.
통상적으로 엔진의 연소실에서 공급된 혼합기가 연소되는 바, 이때 엔진 시동정지와 함께 실린더내의 연소가스가 엔진의 부압으로 인하여 흡기계통으로 역류하게 됨에 따라 역류하는 연소가스에 포함되어 있는 카본이 흡기계통에 흡착되어 트로틀 밸브의 작동불량을 초래하고 공회전 액튜에이터 밸브가 막히게 되는 문제점이 있다.Typically, the mixer supplied from the combustion chamber of the engine is combusted. At this time, the combustion gas in the cylinder flows back into the intake cylinder due to the negative pressure of the engine together with the engine start stop. Adsorption causes a malfunction of the throttle valve and the idle actuator valve is blocked.
또한, 상기 흡기계통에 카본이 흡착되는 또 다른 원인으로는 불완전 연소, 흡배기밸브의 오버랩시, 겨울철 엔진온도의 급격한 승하강시 발생되는 습기등에 의하여 흡기계통에 카본이 흡착되어진다.In addition, the carbon is adsorbed to the intake cylinder due to incomplete combustion, the overlap of the intake and exhaust valves, the moisture generated during the sudden rise and fall of the engine temperature in winter.
따라서, 본 발명은 상기와 같은 문제점을 감안하여, 엔진의 부압에 의하여 흡기계통으로 역류하는 카본을 전기로 태워서 흡기 메니폴드로 되돌려 보냄으로써, 엔진의 흡기계통에 카본이 흡착되는 것을 방지할 수 있도록 한 자동차용 흡기계통의 카본 흡착 방지장치를 제공하는데 그 목적이 있다.Therefore, in view of the above problems, the present invention is to burn carbon back to the intake cylinder due to the negative pressure of the engine to return to the intake manifold to prevent the carbon adsorbed to the intake cylinder of the engine. It is an object of the present invention to provide a carbon adsorption preventing device for automobile intake cylinders.

첨부한 도 1은 본 발명에 따른 자동차용 흡기계통의 카본 흡착 방지장치를 나타내는 개략도로서, 도면부호 10은 연소필터이다.1 is a schematic view showing a carbon adsorption preventing device of an intake system for automobiles according to the present invention, wherein 10 is a combustion filter.
상기 연소필터(10)는 전기를 공급받으면 열을 발산하는 코일이 포함되어 있는 통상의 필터로서, 자동차의 흡기메니폴드(24)와 트로틀밸브(28) 사이의 라인상에 연결 설치하는 유입라인(20)에 연결 설치하게 된다.The combustion filter 10 is a conventional filter including a coil for dissipating heat when electricity is supplied. An inlet line 20 is installed on a line between an intake manifold 24 and a throttle valve 28 of an automobile. ) Will be installed.
또한, 상기 연소필터(10)의 유출부에는 솔레노이드 밸브(12)를 연결 설치하는 바, 압력센서를 갖는 라인을 사용하여 연결하게 된다.In addition, the solenoid valve 12 is connected to the outlet of the combustion filter 10 so as to be connected using a line having a pressure sensor.
또한, 상기 솔레노이드 밸브(12)의 유출부에는 진공챔버(14)가 연결설치되고, 진공챔버(14)의 유출부는 흡기메니폴드(24)에 복귀라인(22)을 사용하여 연결하게 된다In addition, a vacuum chamber 14 is connected to an outlet of the solenoid valve 12, and an outlet of the vacuum chamber 14 is connected to the intake manifold 24 using a return line 22.
한편, 상기 연소필터(10)와 솔레노이드 밸브(12)와 압력센서(18)에는 이것들의 작동을 제어하는 연소제어장치(16)가 연결설치되어진다.On the other hand, the combustion filter 10, the solenoid valve 12, and the pressure sensor 18 are provided with a combustion control device 16 for controlling these operations.
여기서 상기와 같이 설치된 본 발명의 자동차용 흡기계통의 카본 흡착 방지장치의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the carbon adsorption preventing device of the intake system for automobiles of the present invention installed as described above are as follows.
엔진의 시동을 오프하면, 실린더로부터 흡기계통으로 엔진의 부압이 작용하면서 카본이 역류되는 바, 이때, 역류된 카본이 유입라인(20)으로 유입되어진다.When the engine is turned off, carbon is flowed back while the negative pressure of the engine is acted on the intake cylinder from the cylinder. At this time, the backflowed carbon is introduced into the inflow line 20.
또한, 엔진의 시동이 오프되었음을 상기 연소제어장치(16)에서 인식하여 상기 연소필터(10)에 전류를 공급하는 신호를 보내게 되고, 연소필터(10)는 상기 유입라인(20)을 통하여 유입되어 흡착되어 있는 카본을 태우게 된다.In addition, the combustion control device 16 recognizes that the engine is turned off and sends a signal to supply the current to the combustion filter 10. The combustion filter 10 flows through the inflow line 20. The carbon adsorbed is burned.
동시에 연소된 카본은 연소필터(10)의 유출부로 빠져나가게 되는 바, 이때의 압력이 상기 압력센서(18)에서 감지되는 동시에 연소제어장치(16)로 보내어지고, 이 연소제어장치(16)는 상기 솔레노이드 밸브(12)에 전류신호를 보내어 밸브는 열리게 된다.At the same time, the carbon burned is discharged to the outlet of the combustion filter 10. At this time, the pressure is sensed by the pressure sensor 18 and sent to the combustion control device 16. The combustion control device 16 The solenoid valve 12 sends a current signal to open the valve.
즉, 압력센서(18)에서 감지된 연소된 카본의 유입압력이 기준치보다 크면,연소제어장치(16)는 상기 솔레노이드 밸브(12)에 열림 전류 신호를 보내게 되고, 기준치보다 작으면 열림 전류신호를 보내지 않아 닫힘상태가 유지되어진다.That is, if the inflow pressure of the burned carbon detected by the pressure sensor 18 is greater than the reference value, the combustion control device 16 sends an open current signal to the solenoid valve 12, and if less than the reference value, the open current signal. Closed state is maintained by not sending.
이어서, 상기 연소필터(10)를 빠져나온 연소된 카본은 열림상태의 솔레노이드 밸브(12)를 통과하여 진공챔버(14)에 저장되었다가 체크밸브(30)를 통과하여 복귀라인(22)을 걸쳐 흡기메니폴드(24)로 복귀되어진다.Subsequently, the burnt carbon exiting the combustion filter 10 is stored in the vacuum chamber 14 through the solenoid valve 12 in the open state, and then passes through the return line 22 through the check valve 30. The intake manifold 24 is returned.
한편, 엔진의 시동이 온(ON)되면, 상기 연소제어장치(16)는 연소필터(10)에 전류신호를 차단하여 작동을 멈추게 하는 동시에 솔레노이드 밸브(12)에 전류신호를 밸브를 오프시킨다.On the other hand, when the engine is started (ON), the combustion control device 16 cuts off the current signal to the combustion filter 10 to stop the operation and at the same time turn off the valve to the solenoid valve 12 the current signal.
이상에서 본 바와 같이, 본 발명에 따른 자동차용 흡기계통의 카본 흡착 방지장치에 의하면, 엔진의 시동 정지시의 부압을 이용하여, 흡기계통에 흡착되는 카본을 태워서 없애줌으로써, 기존에 흡착되는 카본에 의하여 발생하던 트로틀 밸브와 공회전 솔레노이드 밸브의 막힘 현상을 방지할 수 있는 잇점이 있다.As described above, according to the carbon adsorption prevention device of the intake cylinder for automobiles according to the present invention, by using the negative pressure at the start-up and stop of the engine, the carbon adsorbed to the intake cylinder is burned and removed, There is an advantage that can prevent the clogging of the throttle valve and the idle solenoid valve generated by the.
