Abstract

PURPOSE: A blow-by gas control apparatus is provided to restrain output increase of an engine and discharge of exhaust emission due to change of a turbocharger by sustaining uniform the quantity of blow-by gas and pressure in a crank. CONSTITUTION: In a turbocharger mounting diesel engine, a hollow core pipe(10) having an oil hole(11) is formed between a turbocharger(40) and an oil separator(41). If intake flow becomes strong due to operation of the turbocharger while blow-by gas is discharged toward intake air, a rubber plate(30) closes the upper end of the hollow core pipe against the elastic force of a spring(20). Therefore, quantity of the blow-by gas less than a specific level and pressure in a crank are sustained uniform within a range regardless of combustion efficiency of an engine. Therefore, output increase of the engine and discharge of exhaust emission due to change of the turbocharger are restrained.

일반적으로 자동차에 적용되어 사용되는 디젤엔진은 제1도에 도시되는 바와 같이 자연흡기식과는 달리 강제흡기식(터보차져)에서는 터빈의 구동에 의한 흡입효율이 높아짐에 따라 크랭크케이스, 실린더블럭(1), 실린더헤드(2), 및 오일분리기 (4)를 차례로 거쳐오는 브로우바이 가스를 강력하게 빨아들이므로서 크랭크케이스내 압력이 떨어져 압축효율이 저하되는 한편 실린더내 블로우바이 가스를 연소실로부터 더 빨아들이기 때문에 연소효율이 크게 저하되는 문제점이 발생되었다.In general, diesel engines applied to automobiles have a crankcase and a cylinder block as shown in FIG. 1, in contrast to a natural intake type. ), The pressure in the crankcase is lowered and the compression efficiency is lowered while the suction of the browby gas passing through the cylinder head (2) and the oil separator (4) in turn is reduced. Because of this problem, the combustion efficiency is greatly reduced.

본 발명은 상기와 같은 종래의 문제점을 해소하기 위해 안출한 것으로, 엔진 연소효율에 영향을 미치지 않는 범위내에서 일정이하의 브로우바이 가스량과 크랭크내 압력을 일정하게 유지시켜 터보차져 변화에 따른 엔진의 출력상승 및 배기가스를 저감할 수 있도록 한 터보차져 장착 디젤엔진의 브로우바이 가스조절 장치를 제공 하는데 목적이있다.The present invention has been made in order to solve the above-mentioned conventional problems, the engine of the engine according to the change of the turbocharger by maintaining a constant browby gas amount and the pressure in the crank within a certain range within a range that does not affect the engine combustion efficiency It is an object of the present invention to provide a browby gas regulating device for a diesel engine equipped with a turbocharger, which can reduce output increase and exhaust gas.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로 터보차져와 오일분리기 사이에 오일구멍이 형성된 중공파이프를 형성하고, 브로우바이가스가 흡기측으로 배출되다가 터보차져가 작동되어 흡입유동이 강해지면 지지하고 있단 스프링의 스프링력을 극복하고 상기 중공파이프의 상단부를 차단하는 고무판으로 구성된다.The present invention forms a hollow pipe having an oil hole formed between the turbocharger and the oil separator as a means for achieving the above object, and the browby gas is discharged to the intake side, the turbocharger is activated to support the suction flow becomes stronger It consists of a rubber plate which overcomes the spring force of the spring and blocks the upper end of the hollow pipe.

이하 본 발명의 일실시예에 의하여 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to an embodiment of the present invention will be described in detail.

본 발명은 제2도에 도시되는 바와 같이, 터보차져로 구동되는 디젤엔진에 있어서, 터보차져(40)와 오일분리기(41) 사이에 오일구멍(11)이 형성된 중공파이프 (10)를 형성하고, 브로우바이 가스가 흡기측으로 배출되다가 터보차져 (40)가 작동되어 흡입유동이 강해지면 지지하고 있던 스프링(20)의 스프링력을 극복하고 상기 중공파이프(10)의 상단부를 차단하는 고무판(30)으로 구성함을 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, in the diesel engine driven by the turbocharger, the hollow pipe 10 having the oil hole 11 is formed between the turbocharger 40 and the oil separator 41. When the blow-by gas is discharged to the intake side and the turbocharger 40 is operated to increase the suction flow, the rubber plate 30 overcomes the spring force of the supported spring 20 and blocks the upper end of the hollow pipe 10. The configuration is a basic feature of the technical configuration.

이와 같이 구성된 본 발명은, 터보차져(40)와 오일분리기(41) 사이에 중공파이프(10)를 형성하고, 이 중공파이프(10)의 상부에 고무판(30)이 위치할수 있도록 스프링(20)을 설치한다.According to the present invention configured as described above, the hollow pipe 10 is formed between the turbocharger 40 and the oil separator 41, and the spring 20 is positioned so that the rubber plate 30 is positioned on the hollow pipe 10. Install it.

상기와 같이 브로우바이 가스 조절장치가 설치되면 평소에는 고무판(30)사이와 중공파이프(10), 및 오일구멍(11)등으로 브로우바이 가스가 흡기측으로 배출되다가 터보차져(40)가 작동되고 흡기측의 흡기유동이 강해지면 스프링(20)으로 지지되어 있던 고무판(30)이 강한 흡입압력에 의해 상기 스프링(20)의 스프링력을 극복하면서 중공파이프(10)의 상단부를 완전히 차단하게 된다.When the browby gas adjusting device is installed as described above, the browby gas is discharged to the intake side between the rubber plate 30, the hollow pipe 10, and the oil hole 11, and the turbocharger 40 is operated. When the intake flow on the side becomes stronger, the rubber plate 30 supported by the spring 20 completely blocks the upper end of the hollow pipe 10 while overcoming the spring force of the spring 20 by the strong suction pressure.

상기와 같이 고무판(30)이 중공파이프(10)의 상단을 밀폐시키면 브로우바이 가스는 오일분리기(41)를 통과한 미소량의 오일과 함께 오일구멍(11)으로만 통과하게 되고 상기와는 반대로 흡입압력이 떨어지면 고무판(30)은 스프링(20)의 스프링력에 의해 자동으로 원상복귀된다.As described above, when the rubber plate 30 seals the upper end of the hollow pipe 10, the browby gas passes only through the oil hole 11 together with a small amount of oil passing through the oil separator 41. When the suction pressure drops, the rubber plate 30 is automatically returned to its original state by the spring force of the spring 20.

이상에서 살펴본 바와 같이 본 발명은, 터보차져와 오일분리기 사이에 중공파이프를 형성하고, 브로우바이가스가 흡기측으로 배출되다가 터보차져가 작동되어 흡입유동이 강해지면 지지하고 있던 스프링의 스프링력을 극복하고 상기 중공파이프의 상단부를 차단하는 고무판을 마련하여, 엔진 연소효율에 영향을 미치지 않는 범위내에서 일정이하의 브로우바이 가스량과 크랭크내 압력을 일정하게 유지시켜 터보차져 변화에 따른 엔진의 출력상승 및 배기가스를 저감할 수 있는등의 효과가 있는 것이다.As described above, in the present invention, a hollow pipe is formed between the turbocharger and the oil separator, and when the browby gas is discharged to the intake side, the turbocharger is operated to overcome the spring force of the spring supported by the suction flow. By providing a rubber plate to block the upper end of the hollow pipe, and maintains a constant brow by gas amount and pressure in the crank within a range that does not affect the engine combustion efficiency to increase the output and exhaust of the engine according to the turbocharger change The effect is that the gas can be reduced.
