In addition, it sends out the burned gas. At the same time, the compression stroke and the power stroke adhere to the valve seat to maintain airtightness.
상기 엔진은 각 행정 즉 실린더내에서 압축 폭팔하는 과정에서 상당한 열이 발생되고 이 열은 지속적으로 냉각을 지켜주어야 된다.The engine generates a significant amount of heat during each stroke, that is, during compression and detonation in the cylinder, and this heat must be kept constantly cooled.
그리고 터보엔진은 엔진외부에서 콤프레셔를 이용하여 공기를 강제적으로 공급하고 압축하여 연소실에서 연료와 혼합연소시켜 고온·고압의 가스로 하므로서 그것이 엔진을 강제적으로 돌리게 되고 터어빈과 배기관을 통해 배기가스를 유출시키게 된다.In addition, the turbo engine is forced to supply and compress air by using a compressor from outside the engine to be mixed and burned with fuel in the combustion chamber to produce a high temperature and high pressure gas, which turns the engine forcibly and causes the exhaust gas to flow out through the turbine and exhaust pipe. do.
그런데 상기 터어빈과 배기관을 통해 배기가스가 유출되면 배기가스의 압력이 증가하게 되고 이로인하여 출력이 저감되는 문제점이 있었던 것이다.However, when the exhaust gas flows out through the turbine and the exhaust pipe, the pressure of the exhaust gas is increased, thereby reducing the output.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로, 터보엔진의 배기가스가 유출되는 배기관에 2차적으로 터어빈과 콤프레샤를 설치하므로서, 엔진의 배압이 멀어지면서 연소가스의 배출이 용이해져 공기충진을 더욱 향상시켜 체적효율(體積效率)의 향상을 통해 출력을 향상시킨 2단계 터보차저를 이용한 배압저감장치에 관한 것을 제공함을 목적으로 한다.The present invention has been devised in view of the above problems, and by installing the turbine and the compressor secondly in the exhaust pipe where the exhaust gas of the turbo engine is discharged, the exhaust gas of the engine becomes far away, and the combustion gas is easily discharged, thereby providing air filling. An object of the present invention is to provide a back pressure reduction device using a two-stage turbocharger that further improves output by improving volumetric efficiency.
