Abstract
Description
본 발명은 터보차저가 채용된 차량에 관한 것으로서, 보다 상세하게는 차량의 초기 가속 성능과 발진 성능을 향상시키기 위해 개선된 터보차저가 채용된 차량에 관한 것이다.The present invention relates to a vehicle employing a turbocharger, and more particularly, to a vehicle employing an improved turbocharger for improving the initial acceleration performance and the oscillation performance of a vehicle.
터보 인터쿨러 디젤엔진은 터빈과 컴프레서로 구성되는 터보차저가 채용되어 있어 흡입 공기량을 증가시켜 출력을 향상시키는 구조를 이루고 있다. 즉, 배기가스가 배기관을 통해 터빈을 통과하면서 이 터빈에 에너지를 공급하게 되고, 터빈은 축에 의해 연결된 컴프레서에 상기와 같은 에너지를 회전에너지로 전달하게 된다.The turbo intercooler diesel engine employs a turbocharger composed of a turbine and a compressor, thus increasing the amount of intake air and improving output. In other words, the exhaust gas passes through the turbine through the turbine to supply energy to the turbine, and the turbine delivers the above energy as a rotational energy to a compressor connected by a shaft.
이때, 상기 컴프레서는 흡입공기를 압축한 후 이를 인터쿨러와 플래넘 챔버를 통해 흡기 매니폴드로 보냄으로써 흡입공기는 자연흡기엔진에 비해 높은 밀도로 엔진에 공급되는 것이다.At this time, the compressor compresses the intake air and sends it to the intake manifold through the intercooler and the plenum chamber so that the intake air is supplied to the engine at a higher density than the natural intake engine.
그러나 종래의 터보차저 장착 엔진은 차량이 발진시 터보 래그 현상으로 인해 흡입 공기량이 부족하여 그 출력이 일시적으로 적게 나오는 현상이 있으며, 특히 경사로에서 등판 발진시 터보랙 현상이 심하여 엔진의 출력저하 및 매연의 다량 방출 원인이 되는 문제점이 있다.However, the conventional turbocharged engine has a phenomenon in which the output is temporarily reduced due to insufficient intake air due to the turbo lag phenomenon when the vehicle starts, especially, the engine output decreases and smokes due to the severe turbo rack phenomenon when starting the ramp on the slope. There is a problem that causes a large amount of release.
즉, 엔진의 부하나 회전수가 급격히 변화할 때 터빈에 전달되는 에너지의 일부만이 컴프레서로 전달되고, 나머지는 터보차저의 관성을 이긴 후 그 회전부품들을 가속시키는데 사용하는 관계로 엔진이 가속하거나 부하가 증가할 때 공급되는 부스트압은 동일한 순간 회전수와 연료량에 대해 정상상태일 때에 비하여 낮은 수준을 유지하는 폐단이 따랐다.In other words, when the load or rotational speed of the engine changes drastically, only a part of the energy delivered to the turbine is transferred to the compressor, and the rest is used to accelerate the rotating parts after the turbocharger inertia. Increasing the boost pressure was followed by a closed end that maintained a low level compared to the steady state for the same instantaneous rotational speed and fuel volume.
그러므로 상기와 같은 폐단으로부터 흡입 공기량이 그 분사연료량이 연소하는데 정상적으로 공급되는 공기량에 비하여 부족함을 의미하고, 이로 인해 엔진의 연소성능이 저하되어 스모크(smoke) 발생과 더불어 순간 토크 부족을 유발하게 되었다.Therefore, the amount of intake air from such a closed end is insufficient compared to the amount of air normally supplied to the injected fuel amount, which causes the combustion performance of the engine to deteriorate, which causes smoke and instantaneous torque shortage.
즉, 종래에는 터보차저의 관성으로 인해 컴프레서가 충분히 빨리 흡입공기를 공급하지 못함으로써 상기와 같은 터보 래그 현상은 불과 수 사이클의 엔진 회전기간 동안 무부하와 전부하 연료의 연료량 차이가 큰 높은 마력의 엔진일수록 심하게 발생되는 문제점이 있다.That is, the conventional turbocharger does not supply the intake air fast enough due to the inertia of the turbocharger. Thus, the turbo lag phenomenon is a high horsepower engine having a large difference in fuel amount between no-load and full-load fuel during only a few cycles of engine rotation. There is a problem that occurs more severe.
그리고 가변용량 제어 터보차저(VGT) 엔진의 경우, 배기가스 에너지를 효율적으로 이용하기 위해서 터빈측에 베인 기구를 설치하여 성능 향상을 달성할 수 있지만 로터의 관성이 일반적인 터보차저(WGT) 대비 두 배 이상 커지므로 초기 발진 성능 및 등판 성능이 떨어지고, 상기 베인 기구 설치로 인하여 내구성이 떨어지고 가격이 증가되는 문제점이 있다.In the case of a variable capacity turbocharger (VGT) engine, a vane mechanism can be installed on the turbine side to efficiently use exhaust gas energy, but the inertia of the rotor is twice that of a conventional turbocharger (WGT). The larger the ideal, the lower the initial oscillation performance and the climbing performance, there is a problem that the durability is lowered and the price is increased due to the vane mechanism installation.
본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 터보 래그의 발생 억제와 등판 성능 및 발진 가속 성능을 향상시키며, 가격을 저감되도록 한 터보차저가 채용된 차량을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a vehicle in which a turbocharger is employed to improve the generation of the turbo lag, improve the climbing performance and the acceleration acceleration performance, and to reduce the price.

도 1에는 본 발명에 따른 터보차저가 채용된 차량의 구성을 개략적으로 나타낸 블록도가 도시되어 있다.1 is a block diagram schematically showing the configuration of a vehicle employing a turbocharger according to the present invention.
도면을 참조하면, 본 발명에 따른 터보차저가 채용된 차량은, 엔진(10)과, 이 엔진(10)의 일측에 설치되고 전자 클러치가 내장된 공기 압축기(20)와, 차량의 감속시 및 엔진 브레이크시 불필요하게 발산되는 에너지를 차량의 엔진제어장치인 ECU의 신호에 따라 전자클러치를 작동시켜 상기 공기 압축기(20)를 가동 및 저장되도록 공기 압축기(20)와 연결 설치된 압축탱크(30)와, 상기 ECU의 신호에 따라 개폐되도록 압축탱크(30)와 연결 설치된 분사밸브(32)와, 이 분사밸브(32)와 연결 설치되어 압축탱크(30)에 저장된 공기를 공급받는 터보차저(40)를 포함하여 구성된다.Referring to the drawings, a vehicle employing a turbocharger according to the present invention includes an engine 10, an air compressor 20 installed at one side of the engine 10, and an electronic clutch built therein; Compression tank 30 connected to the air compressor 20 to operate and store the air compressor 20 by operating the electronic clutch according to the signal of the ECU, which is an engine control device of the vehicle, to the energy released during the engine brake; , A turbocharger 40 connected to the compression tank 30 so as to be opened and closed according to a signal of the ECU, and a turbocharger 40 connected to the injection valve 32 and supplied with air stored in the compression tank 30. It is configured to include.
상기 분사밸브(32)는 터보 래그 발생될 때 또는 주행정항이 증가될 때 오픈(open)되도록 이루어진다.The injection valve 32 is configured to open when the turbo lag is generated or when the driving regulation is increased.
한편, 도 1에서 설명되지 않은 참조부호 C1 내지 C4는 엔진(10)의 실린더이고, 31은 릴리프 밸브이며, 50, 60, 70은 인터쿨러, 에어 클리너, 촉매변환기이다.On the other hand, reference numerals C1 to C4 which are not described in FIG. 1 are cylinders of the engine 10, 31 are relief valves, and 50, 60, and 70 are intercoolers, air cleaners, and catalytic converters.
상기한 바와 같은 구성을 갖는 본 발명에 따른 터보차저가 채용된 차량의 작용을 설명하면 다음과 같다.Referring to the operation of the vehicle employing the turbocharger according to the present invention having the configuration as described above is as follows.
도 2에는 본 발명에 따른 터보차저가 채용된 차량의 작동을 순차적으로 나타내 보인 개략적인 플로차트가 도시되어 있다.2 is a schematic flowchart showing the operation of a vehicle employing a turbocharger according to the present invention in sequence.
도면을 다시 참조하면, 본 발명에 따른 터보차저가 채용된 차량은, 내리막길, 엔진 브레이크 및 감속시 차량에서 압력원인 공기 압축기(20)가 작동하는지 판단한다.(단계 110)Referring back to the drawings, in the vehicle employing the turbocharger according to the present invention, it is determined whether the air compressor 20, which is the pressure source in the vehicle at the time of the downhill, the engine brake and the deceleration, is operated.
상기 단계 110에서 공기 압축기(20)가 작동된다고 판단되면 이 공기 압축기(20)에 내장된 전자클러치를 작동(on)시키고, 이를 압축용기인 압축탱크(30)에 저장한다.(단계 120,130) 상기 단계 130에서 압축용기의 압축탱크(30)가 규정압 이상이면 공기를 외기로 방출한다.(단계 131)If it is determined in step 110 that the air compressor 20 is operated, the electronic clutch built in the air compressor 20 is turned on and stored in the compression tank 30, which is a compression container (steps 120 and 130). If the compression tank 30 of the compression vessel is greater than the prescribed pressure in step 130, the air is discharged to the outside.
그리고 터보차저(40)의 터빈이 분출되고 있는지 판단된다.(단계 140)Then, it is determined whether the turbine of the turbocharger 40 is ejected (step 140).
상기 단계 140에서 터빈이 분출되면 엔진(10)의 출력이 증대된다.(단계 150)When the turbine is ejected in the step 140, the output of the engine 10 is increased (step 150).
한편, 상기 단계 110에서 압력원이 작동되지 않은 경우, 상기 전자클러치를 오프(off)시킨다.(단계 111)On the other hand, when the pressure source is not operated in step 110, the electronic clutch is turned off (step 111).
상기한 바와 같이 본 발명은, 차량의 감속시 및 엔진 브레이크시 등 불필요하게 발산되는 에너지를 ECU의 신호에 따라 전자클러치를 작동시켜 공기 압축기(20)를 가동하여 압축탱크(30)에 저장한다.As described above, according to the present invention, energy that is unnecessarily released, such as when the vehicle is decelerated and when the engine is braked, is operated by the electronic clutch in response to a signal from the ECU to operate the air compressor 20 to store it in the compression tank 30.
그리고 차량의 터보 래그가 발생되는 조건 예컨대, 초기 발진, 추월 발진, 등판 가속 등에서 ECU의 신호에 따라 분사밸브(32)가 열려 압축탱크(30)에 저장된 공기가 초고압으로 터보차저(40)의 터빈(T)으로 공급되어 터빈 회전수가 급속히 고속 회전됨에 따라 부스트 압력 상승으로 엔진(10) 출력이 높아지고, 따라서 순간 가속 성능이 좋아지게 된다.The injection valve 32 is opened in response to an ECU signal in a condition in which a turbo lag of the vehicle is generated, for example, initial oscillation, overtaking oscillation, climbing acceleration, etc., and the air stored in the compression tank 30 is ultra-high pressure turbine of the turbocharger 40. As the turbine rotation speed is rapidly rotated at high speed, the engine 10 output is increased due to the boost pressure increase, and thus, the instantaneous acceleration performance is improved.
또한 언덕 주행과 같은 일반 주행시 주행 저항이 증가될 때, 상기 분사밸브(32)를 오픈시키게 되면 터빈의 회전수가 증가되고, 이에 따라 엔진(10)의 출력이 증대되고, 끈끈하고 강인한 엔진(10)으로 주행 능력 및 상품성이 향상된다.In addition, when the driving resistance is increased during normal driving such as hill driving, opening the injection valve 32 increases the number of revolutions of the turbine, thereby increasing the output of the engine 10, and making the sticky and robust engine 10. This improves the driving ability and the merchandise.
상술한 바와 같이 본 발명에 따른 터보차저가 채용된 차량은 다음과 같은 효과를 갖는다.As described above, the vehicle employing the turbocharger according to the present invention has the following effects.
일반 터보차저 및 가변용량제어 터보차저가 채용된 차량에 비해 차량의 초기 가속 성능이 향상되고, 터보차저 차량의 문제점인 발진성능을 향상시킬 수 있다.Compared to a vehicle employing a general turbocharger and a variable capacity turbocharger, the initial acceleration performance of the vehicle is improved, and the oscillation performance, which is a problem of the turbocharger vehicle, can be improved.
그리고 차량의 파워가 떨어지는 경우 추가 부스트의 작동으로 강인한 엔진 토크를 유지할 수 있다.And if the car's power drops, it can maintain robust engine torque with an additional boost.
본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 보호 범위는 첨부된 특허청구범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
