본 고안은 터보차저 엔진의 과급압 조절장치에 관한 것으로서, 특히 연소실로 공급되는 압축 공기의 압력이 규정압 이상으로 상승될 경우, 과급된 흡입 공기를 배기계로 바이패스 시켜 과급 압력을 규정치로 제어하는 저속 중시형 과급압력 조절장치에 관한 것이다.The present invention relates to a boost pressure regulating device of a turbocharger engine. In particular, when the pressure of the compressed air supplied to the combustion chamber rises above a predetermined pressure, the boosted intake air is bypassed to the exhaust system to control the boost pressure to a prescribed value. It relates to a low-speed focused type supercharge pressure regulator.
주지된 바와 같이, 자동차의 엔진은 혼합기의 연소 및 압축 착화에 이해 구동력을 발생시키는 것으로서, 엔진 배기량을 크게 하면 출력도 증가된다.As is well known, the engine of an automobile generates a driving force for combustion and compression ignition of a mixer, and when the engine displacement is increased, the output also increases.
그러나 배기량이 작은 소형 엔진이나 동일한 배기량의 엔진이라도, 많은 양의 공기를 실린더에 흡입 즉, 과급(過給)토록 하면, 엔진의 출력을 높일 수 있다.However, even in a small engine with a small displacement or an engine of the same displacement, the output of the engine can be increased by allowing a large amount of air to be sucked into the cylinder, i.e., supercharging.
이러한 사실에 근거하여, 종래에는 흡입 부압에 의해 공기를 흡입하는 외에 강제적으로 공기를 실린더로 압송시키도록 한 터보차저 장치가 제안되어 있다.On the basis of this fact, conventionally, a turbocharger device has been proposed in which air is forced to be forced into a cylinder in addition to suctioning air by suction negative pressure.
종래 공지된 터보차저는 도 1에 상세하게 도시된 바와 같이, 배기관(1)를 통하여 대기중으로 버려지는 배기가스의 압력을 이용하여 터빈(3)을 회전시키고, 그 터빈(3)과 동일 축선상에 연결된 컴프레서(5)가 흡기관(7)를 통하여 유입되는 공기를 과급시켜, 연소실(9)로 강제 공급토록 한다.The conventionally known turbocharger rotates the turbine 3 using the pressure of the exhaust gas which is thrown into the atmosphere through the exhaust pipe 1, as shown in detail in FIG. 1, and coaxial with the turbine 3. The compressor 5 connected to the supercharger charges the air flowing in through the intake pipe 7 to be forcedly supplied to the combustion chamber 9.
종래 기술에서 설명된 터보차저 엔진에 있어서는, 엔진의 고속 운전시 컴프레서를 통하면서 과도하게 압축된 공기가 연소실로 유입되어, 이상 연소를 일으키는 문제점이 있다.In the turbocharged engine described in the prior art, there is a problem that excessively compressed air flows into the combustion chamber through the compressor during the high speed operation of the engine, causing abnormal combustion.
이러한 종래 기술의 문제점을 해소하기 위하여 안출된 것으로서, 본 고안은 연소실로 공급되는 과급 공기의 일부를 배기계로 바이패스시켜, 특히 엔진의 고속운전시 컴프레서에 의해 발생되는 과도한 압력의 형성을 제한할 수 있도록 한 터보차저 엔진의 과급압력 조절장치를 제공함에 있다.In order to solve the problems of the prior art, the present invention bypasses a part of the boost air supplied to the combustion chamber to the exhaust system, and in particular, can limit the formation of excessive pressure generated by the compressor during high speed operation of the engine. To provide a boost pressure regulator for a turbocharged engine.

도면에서의 설명 부호 (1)은 배기관, (3)은 배기관에 설치된 터빈, (5)는 흡기관에 설치된 컴프레서, (7)는 흡기관, (9)는 연소실을 지칭한다.In the drawings, reference numeral 1 denotes an exhaust pipe, 3 denotes a turbine installed in the exhaust pipe, 5 denotes a compressor installed in the intake pipe, 7 denotes an intake pipe, and 9 denotes a combustion chamber.
이와 같은 구성을 포함하는 터보차저 엔진은 배기관(1)를 통하여 대기중으로 배출되는 배기가스가 터빈(3)을 회전시키고, 그 터빈(3)과 동일 축선상에 연결된 컴프레서(5)가 흡기관(7)을 통하여 유입되는 공기를 과급시켜, 연소실(9)로 강제 공급토록 한다.In the turbocharger engine having such a configuration, the exhaust gas discharged into the atmosphere through the exhaust pipe 1 rotates the turbine 3, and the compressor 5 connected to the turbine 3 on the same axis has an intake pipe ( 7) supercharges the air introduced through the forced supply to the combustion chamber (9).
여기서, 본 고안은 컴프레서(5)에 의해 과도하게 형성된 압축 공기의 압력을 제어할 수 있도록 하는 과급압력 조절수단을 제안한다.Here, the present invention proposes a boost pressure regulating means for controlling the pressure of the compressed air excessively formed by the compressor (5).
이를 위하여, 본 고안의 과급압력 조절수단은 흡기관(7)과 배기관(1)의 사이에 연결되는 바이패스관(11)상에 설치되며, 흡기관(7)에 형성되는 컴프레서(5)에 의한 과도한 과급압에 의해 개폐되도록 구성된다.To this end, the boost pressure adjusting means of the present invention is installed on the bypass pipe (11) connected between the intake pipe (7) and the exhaust pipe (1), in the compressor (5) formed in the intake pipe (7) It is configured to open and close by excessive boost pressure.
보다 구체적으로, 상기 컴프레서(5)에 의해 압축된 공기의 압력이 규정 압력이상으로 상승되면, 흡기관(7)에 바이패스관(11)으로 연결된 웨이스트 게이트 밸브(13)가 개방되어, 컴프레서(5)에 의해 과도하게 압축된 공기를 배기관(1)으로 바이패스시킨다.More specifically, when the pressure of the air compressed by the compressor 5 rises above the prescribed pressure, the waste gate valve 13 connected to the intake pipe 7 by the bypass pipe 11 is opened to open the compressor ( Bypass the excessively compressed air by 5) to the exhaust pipe (1).
이를 위하여, 상기한 웨이스트 게이트 밸브(13)는 바이패스관(11)의 배기 블록(11a)의 내부에 스프링(15)에 의해 항상 폐쇄되는 방향으로 탄지되는 밸브체(17)로 구성된다.To this end, the waste gate valve 13 is composed of a valve body 17 which is supported in a direction which is always closed by the spring 15 inside the exhaust block 11a of the bypass pipe 11.
또한, 밸브체(17)는 흡기관(7)에 규정 이상의 압력이 발생되면, 바이패스관(11)을 통하여 공급되는 과급 압력에 의해 개방된다.In addition, when the valve body 17 generate | occur | produces more than the prescribed pressure in the intake pipe 7, it will open by the boost pressure supplied through the bypass pipe 11.
여기서, 상기 밸브체(17)는 고정핀(19)을 개재하여 리테이너(21)에 고정된다.Here, the valve body 17 is fixed to the retainer 21 via the fixing pin 19.

컴프레서(5)에 의해 흡기관(7)에 규정 이상의 과도한 압력이 발생되면, 그 과급압이 바이패스관(11)으로 공급되고, 그 압력에 의해 밸브체(17)가 도면의 좌측 방향으로 밀려지면서, 바이패스관(11)을 개방한다.When excessive pressure is exceeded by the compressor 5 in the intake pipe 7, the boost pressure is supplied to the bypass pipe 11, and the valve body 17 is pushed to the left side of the figure by the pressure. While opening, the bypass pipe 11 is opened.
따라서, 과도하게 과급된 흡입 공기를 바이패스관(11)을 거쳐 배기관(1)으로 바이패스된다.Therefore, excessively supercharged intake air is bypassed to the exhaust pipe 1 via the bypass pipe 11.
한편, 컴프레서(5)에 의해 생성된 과급압이 규정 이하로 될 경우에는, 상기 밸브체(17)가 스프링(15)의 힘에 의해 도면의 우측 방향으로 이동되어, 바이패스관(11)을 폐쇄한다.On the other hand, when the boost pressure generated by the compressor 5 becomes below the prescribed value, the valve body 17 is moved to the right direction in the drawing by the force of the spring 15, thereby to bypass the bypass pipe 11. To close.
이상에서 설명된 구성 및 작용을 통하여, 본 고안에 의한 터보차저 엔진의 과급압 조절장치는 종래 기술의 문제점을 실질적으로 극복하고 있다.Through the configuration and action described above, the boost pressure regulating device of the turbocharger engine according to the present invention substantially overcomes the problems of the prior art.
