본 고안은 브리더 호스에서 나오는 블르바이 가스를 드로틀 보디를 거치지 않고 써지탱크로 직접 유입되게한 드로틀의 카본방지구조에 관한 것이다.The present invention relates to a carbon prevention structure of a throttle which allows the blow-by gas from the breather hose to be directly introduced into the surge tank without passing through the throttle body.
종래, 자동차 시동을 걸면 4행정하는데 압축 또는 폭발시 완전하게 연소하지 못한 블르바이 가스(예를 들면, 주성분이 HC, CO 가스로써 압축 또는 폭발시 미연소 가스가 크랭크로 올라와 크랭크 축 및 기관을 녹이 슬게 만들고, 대기중으로 방출되어 대기를 오염시킨다.)를 경중 부하시에는 P. C. V 밸브(예를 들면 경중부하시 흡기 다기관의 진공힘으로 흡기 다기관내로 블로바이 가스를 유입하는 장치)를 통하여 양이 줄어들기 때문에 드로틀 보디를 거치지 않고 흡기 다기관 내로 직접 유입되지만, 고부하시에는 가스의 양이 많아 지기 때문에, 상기 가스가 브리더 호스를 통하여 흡기 계통 즉 드로틀 보디를 걸쳐서 흡기 다기관을 통과하여 연소실로 유입된다.Conventionally, when a vehicle is started, a four-stroke engine is not completely burned when compressed or exploded (for example, when the main component is HC or CO gas, the unburned gas rises to the crank to melt the crankshaft and engines). At low loads, the volume is reduced through a PC V valve (e.g., a device that blows blow-by gas into the intake manifold with the vacuum force of the intake manifold at light loads). As it decreases, it flows directly into the intake manifold without passing through the throttle body, but at high loads, the amount of gas increases, and the gas flows into the combustion chamber through the intake manifold through the breather hose, ie, through the throttle body.
이 때, 브리더 호스에서 나오는 블르바이 가스가 드로틀 보디를 통과하는 사이에 상기 블르바이 가스 자체는 실린더 헤드 내의 오일과 혼합하여 끈끈한 점도를 가진 액체로 변형되어 드로틀 보디에 엉켜붙어 엔진의 열로 인한 카본 또는 기타 이물질로 변하여 드로틀 보디의 기능을 저해하여 저속시 rpm을 불규칙하게 하고, 고속시에는 차가 울컥거리는 현상을 발생시키고 심한 경우에는 시동이 꺼지는 현상이 발생되었다.At this time, while the blow-by gas from the breather hose passes through the throttle body, the blow-by gas itself is mixed with the oil in the cylinder head and transformed into a liquid having a sticky viscosity, which is entangled with the throttle body, causing carbon or It changed to other foreign materials and inhibited the function of the throttle body, causing the rpm to be irregular at low speed, causing the car to flutter at high speed, and in some cases, starting off.
본 고안의 목적은, 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 브리더 호스에서 나오는 블르바이 가스를 드로틀 보디를 거치지 않고 써지탱크 내로 유입되게 하여 블르바이 가스의 양을 rpm을 감지하여 컴퓨터가 공기유량 센서(A. F. S)를 이용하여 공기의 양을 증감할 수 있게 하여 드로틀 보디 내에 카본 및 이물질을 방지하는데 있다.An object of the present invention is to solve the conventional problems as described above, by allowing the blow-by gas from the breather hose to be introduced into the surge tank without passing through the throttle body to detect the rpm of the amount of the blow-by gas and the computer The flow rate sensor AF S allows the amount of air to be increased or decreased to prevent carbon and foreign matter in the throttle body.
상기와 같은 목적을 달성하기 위하여 본 고안 드로틀 보디 내로 유입되는 카본의 방지구조는, 드로틀 바디와, 써지탱크 및 이들을 제어하기 위한 컴퓨터와, 블르바이 가스를 억제하기 위한 브리더호스를 구비한 카본 방지구조에 있어서, 상기 브리더호스를 드로틀 보디를 거치지 않고 써지탱크 내로 직접 유입되게 하므로서 상기 드로틀 보디에 퇴적되는 카본 및 이물질을 방지하는 것을 특징으로 한다.In order to achieve the above object, a carbon preventing structure introduced into the throttle body of the present invention includes a throttle body, a surge tank, a computer for controlling them, and a carbon preventing structure including a breather hose for suppressing blowby gas. In the air, the breather hose is directly introduced into the surge tank without passing through the throttle body to prevent carbon and foreign matter deposited on the throttle body.
이하 본 고안의 기술적 구성 및 효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration and effects of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안의 연료 분사장치의 계통도로서 브리더호스(1)를 드로틀 보디(2)를 거치지 않고 써지탱크(이하, 흡기 다기관이라고함)(3)내로 유입되게 하여 컴퓨터(도시하지 않음)가 rpm의 고저에 따라서 공기유량센서(A. F. S)(4)의 증감을 계산하여 혼합비 내의 공기량을 증감하여 혼합비를 결정함으로서 경제적인 연소가 이루어진다.2 is a schematic diagram of a fuel injector according to the present invention, which allows a breather hose 1 to flow into a surge tank (hereinafter referred to as an intake manifold) 3 without passing through the throttle body 2 so that a computer (not shown) Economical combustion is achieved by calculating the increase / decrease of the air flow rate sensor (AF S) 4 in accordance with the height of the rpm to increase or decrease the amount of air in the mixing ratio to determine the mixing ratio.
예를 들면, 압축 또는 폭발시 발생한 블르바이 가스가 브리더호스(1)를 통과하여 즉, 토르틀 보디(2)를 거치지 않고 흡기다기관(써지탱크)(3)내로 유입되게 하므로서 드로틀 보디(2)에 퇴적되는 카본 및 이 물질을 방지하므로서 드로틀 보디의 기능을 올바르게 하여 규칙적인 행정을 이루게하여 차가 울컥거리는 현상과 시동이 꺼지는 현상을 방지하고 이로 인한 배출가스를 줄일 수가 있다.For example, the throttle body 2 allows the blow-by gas generated during compression or explosion to pass through the breather hose 1, that is, into the intake manifold (surge tank) 3 without passing through the tortle body 2. By preventing the carbon and foreign matter deposited on the throttle body, the throttle body functions properly to achieve regular strokes, thereby preventing the car from snarling and turning off the engine and reducing emissions.
