Abstract

PURPOSE: A connector linking a blow-by gas meter with an intake pipe is provided to measure the exact amount of gas and to prevent blow-by gas from flowing to the inside by excluding influence by the suction force of an intake pipe in a low RPM(Revolutions Per Minute) area of an engine. CONSTITUTION: A connector(1) includes: a large and a small funnel member having large diameter portions spread toward a blow-by gas meter(11) and small diameter portions positioned toward an intake pipe(10); an intake side connector(6) extended from the small diameter portion of the large funnel member and contacted with the intake pipe; a meter connector(7) having one side coupled with the small diameter portion of the small funnel member and the other side in contact with the blow-by gas meter; and an external air inlet hole(8) formed at the small funnel member. The intake side connector is connected to the intake pipe while the meter connector is coupled with a pipe(12) passing through the blow-by gas meter. The pipe is in contact with an engine(13), particularly with a crankcase or a locker cover. External air is sucked through the external air inlet hole even though a strong suction force is applied to a low RPM area of the engine from the intake pipe. Therefore, the strong negative pressure of the intake pipe does not influence a point for measuring the pressure of the blow-by gas meter.

Description

블로바이가스 메타기와 흡입 파이프를 연결하는 접속구{Connector blow-by meter and suction pipe}Connector for connecting blow-by gas meta to suction pipes {Connector blow-by meter and suction pipe}

본 발명은 엔진에서 나오는 블로바이가스(Blow-by gas)량을 측정하는 블로바이가스 메타기와 흡입 파이프(Suction pipe)를 연결하는 접속구에 관한 것이다.The present invention relates to a connection port for connecting a blow-by gas meta meter and a suction pipe to measure an amount of blow-by gas emitted from an engine.

피스톤의 압축 및 팽창시 피스톤링의 틈새를 통하여 블로바이가스량을 측정하기 위하여서는 도 5와 도 6에 도시하는 것과 같이 엔진(20)의 크랭크 케이스(또는 로커카바)에 연결관로(21)를 접속하고 연결관로(21)의 도중에는 블로바이가스 메타기(22)를 설치한 후 연결관로(21)의 끝단을 흡입 파이프(23, Suction pipe)에 접속하므로써 로커카바나 크랭크케이스(20)내의 블로바이가스를 흡입 파이프(21)의 흡기부압을 이용하여 빨아들이는 과정에서 블로바이가스 메타기(22)로 그 통과량을 측정하게 된다.In order to measure the blow-by gas amount through the clearance of the piston ring during the compression and expansion of the piston, as shown in FIGS. 5 and 6, the connecting pipe 21 is connected to the crankcase (or rocker cover) of the engine 20. The blow-by gas in the rocker cab or crankcase 20 is formed by installing the blow-by gas meta group 22 in the middle of the connecting pipe 21 and connecting the end of the connecting pipe 21 to the suction pipe 23. In the process of sucking the air using the intake negative pressure of the suction pipe 21, the amount of passage is measured by the blow-by gas meta-device 22.

블로바이가스 메타기(22)는 연결관로(21)의 단면적을 조른 노즐부(24)와, 그 노즐부(24)의 전후 압력을 측정하는 솔레노이드 압력측정기(25)(26)로 구성되며, 압력측정기(25)(26)의 솔레노이드에 전기적인 신호가 입력되면 노즐부(24)의 전후의 압력을 측정(P1, P2)하고 그 압력차를 이용하여 블로바이가스량을 계산해내고 있다.The blow-by gas meta-device 22 is composed of a nozzle portion 24 in which the cross-sectional area of the connecting pipe 21 is cut off, and a solenoid pressure measuring device 25 and 26 measuring the front and rear pressure of the nozzle portion 24. measured before and after the pressure of the pressure meter 25, 26, the nozzle portion 24 when the electrical signal input to the solenoid of the (P 1, P 2) and is put to calculate the blow-by gas quantity by using the pressure difference.

그러나 상기한 종래의 측정 시스템에 의하면 연결관로(21)가 흡입 파이프 (23)에 바로 연결되므로써 블로바이가스량의 측정 원리인 차압력(P1, P2)을 읽어들일 때 엔진에서 나오는 블로바이가스량이 흡입 파이프(23)에서 빨아당기는 양만큼 충분치 아니하면 블로바이가스 측정량이 과대 평가되거나 많은 오차를 보이게 된 다.However, according to the conventional measurement system described above, since the connecting pipe 21 is directly connected to the suction pipe 23, the blow-by gas amount coming from the engine when the differential pressures P 1 and P 2 , which are the principle of measuring blow-by gas amount, are read. If the amount sucked from the suction pipe 23 is not sufficient, the blow-by gas measurement amount is overestimated or shows a lot of errors.

이에따라 상기한 오차를 제거하기 위해 통상적으로 저 RPM 구간에서의 블로바이가스량 측정시엔 흡입부압의 영향을 없애기 위해 연결관로(21)의 단부를 흡입 파이프(23)에 연결하지 아니하고 대기에 개방되도록 하여 측정하고 있으나, 이 경우 인체에 유해한 블로바이가스가 개방된 연결관로(21)의 단부를 통하여 실험실내로 방출되므로 실험자의 건강을 해치고 또 블로바이가스의 주성분인 카본에 의해 건물 벽면이 까맣게 오염되어 실험실 청소를 자주 실시해 주어야 하는 불편함이 있었다.Accordingly, in order to remove the above error, when the blow-by gas amount is measured in the low RPM section, the end of the connecting pipe 21 is opened to the atmosphere without being connected to the suction pipe 23 to eliminate the influence of the suction negative pressure. In this case, however, the blowby gas harmful to the human body is discharged into the laboratory through the open end of the connecting pipe 21, which deteriorates the health of the experimenter, and the building wall is darkly contaminated by carbon, which is the main component of the blowby gas. There was an inconvenience of having to clean frequently.

이에 본 발명은 상기한 문제점을 감안하여 제안한 것으로서 엔진의 저 RPM 운전 영역에서 블로바이가스량을 측정할 때 흡입 파이프의 흡입압에 의한 영향을 배제하여 정확한 가스량을 측정함과 함께 블로바이가스의 실내 방출을 예방하게 되는 블로바이가스 메타기와 흡입 파이프의 연결 접속구를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above problems, and when the blow-by gas amount is measured in the low RPM operating region of the engine, the exhaust gas is discharged indoors while the accurate gas amount is measured by excluding the influence of the suction pressure of the intake pipe. In order to prevent the blow-by gas and the connecting pipe of the suction pipe to provide.

상기한 목적을 달성하기 위하여 본 발명은 엔진으로부터 블로바이가스를 관로를 통하여 흡입 파이프로 흡입하는 도중에 블로바이가스 메타기로써 블로바이가스량을 측정하는 것에 있어서,In order to achieve the above object, the present invention is to measure the amount of blow-by gas with a blow-by gas meta-device during the intake of blow-by gas from the engine through the conduit,

본 발명의 접속구(1)는 대직경부(2)와 소직경부(3)(3')를 각기 갖는 대,소 깔대기 부재(4)(5)와 흡입측 연결부(6)와 메타기측 연결부(7) 및 소깔대기 부재(5)에 형성된 외부공기 유입공(8)으로 구성되어 있다.The connector 1 of the present invention has a large diameter portion 2 and a small diameter portion 3, 3 ', respectively, a large and small funnel member 4, 5, a suction side connection portion 6, and a metabase side connection portion 7. ) And the outside air inlet hole 8 formed in the funnel member 5.

대,소 깔대기 부재(4)(5)의 대직경부(2)는 일체로 되어 있고 깔대기의 테이퍼각(α)(β)이 각기 다르므로 소직경부(3)(3')는 각기 이격되어져 내부공간(9)을 형성하게 되며, 이로써 큰 깔대기 부재(4)의 안쪽으로 작은 깔대기 부재(5)가 위치하는 형상을 이룬다.The large diameter portions 2 of the large and small funnel members 4 and 5 are integrated, and the taper angles α and β of the funnel are different, so that the small diameter portions 3 and 3 'are spaced apart from each other. The space 9 is formed, thereby forming a shape in which the small funnel member 5 is located inside the large funnel member 4.

상기 흡입측 연결부(6)는 큰 깔대기 부재(4)의 소직경부(3)으로부터 연장되며, 상기 메타기측 연결부(7)는 그의 일단이 작은 깔대기 부재(5)의 소직경부(3')에 연결된 채 상기 흡입측 연결부(6)와는 동축상의 반대쪽으로 연장되어 있다.The suction side connection part 6 extends from the small diameter part 3 of the large funnel member 4, and the metabase side connection part 7 is connected at one end thereof to the small diameter part 3 ′ of the small funnel member 5. And extends coaxially with the suction side connecting portion 6.

이와같은 본 발명은 도 4에서와 같이 흡입측 연결부(6)는 흡입 파이프(10)측에 연결하고, 메타기측 연결부(7)는 블로바이가스 메타기(11)를 통과하여 지나는 관로(12)에 접속되고, 그 관로(12)는 엔진(13), 즉 크랭크케이스나 로커카바에 접속되어 있다.In the present invention as shown in FIG. 4, the suction side connection part 6 is connected to the suction pipe 10 side, and the meta machine side connection part 7 passes through the blow-by gas meta device 11. The conduit 12 is connected to the engine 13, i.e., the crankcase and the rocker cover.

이와같이 접속된 상태에서는 블로바이가스 발생량의 적은 엔진의 저 RPM 운전 구간에서 흡입 파이프(10)로부터 강한 흡입력이 작용하더라도 외부공기 유입공(8)을 통하여 외부 공기가 흡입되므로 블로바이가스 메타기(11)의 압력 측정 지점까지는 흡입 파이프(10)의 강한 부압이 영향을 미치지 않게 되는 것이다.In the connected state, even though a strong suction force is applied from the intake pipe 10 in the low RPM operation section of the engine with a small amount of blow-by-gas generation, since the outside air is sucked through the outside air inlet hole 8, the blow-by gas meta-device 11 The strong negative pressure of the suction pipe 10 is not affected until the pressure measurement point of).

이상과 같은 본 발명의 접속구를 블로바이가스 메타기와 흡입 파이프 사이에 접속시켜 놓으면 엔진의 저 RPM 구간에서 접속구에 형성된 외부공기 유입공을 통하여 외부공기가 유입되어져 흡입 파이프의 강한 흡기 부압이 블로바이가스 메타기 까지 미치는 것을 도중에 차단하여 저속 운전시에도 블로바이가스의 대기 방출 없이 정확한 블로바이가스량을 측정할 수 있게 되는 효과가 있다.When the connection port of the present invention is connected between the blow-by gas meta-stage and the intake pipe, external air is introduced through the external air inlet hole formed in the connection port in the low RPM section of the engine, so that the strong intake negative pressure of the suction pipe is blow-by gas. It is effective to measure the amount of blow-by gas without blocking the blow-by gas in the air even at low speed operation by blocking it to the meta machine on the way.
