본 발명은 엔진의 출력향상과 차량의 배기가스를 저감시켜 주는 엔진의 흡기효율 증가장치에 관한 것으로서 더욱 상세하게는 엔진으로 흡입되는 흡입공기에 대한 흡입효율을 엔진의 전운전 영역에서 효과적으로 증대시켜 주므로서 엔진의 연소효율 증가로 인한 엔진의 출력향상과 배기가스의 저감효과가 동시에 제공될 수 있게 구성한 엔진의 흡기효율 증가장치에 관한 것이다.The present invention relates to an engine intake efficiency increasing device for reducing the output of the engine and reducing the exhaust gas of the vehicle. More specifically, the intake efficiency of the intake air sucked into the engine is effectively increased in the pre-operation region of the engine. The present invention relates to an apparatus for increasing the intake efficiency of an engine configured to simultaneously provide an engine output increase and an exhaust gas reduction effect due to an increased combustion efficiency of the engine.
종래에도 실린더의 내부로 흡입되는 흡입공기의 량을 증대시켜 주기 위하여 흡기계의 부품들을 개선한 장치들이 알려진 바 있다.Conventionally, devices have been known that have improved parts of the intake machine to increase the amount of intake air sucked into the cylinder.
예를 들면 인테이크-메니폴드(Intake-Manifold)를 포함한 엔진 실린더 상의 루너부(Runner)로 흡입공기가 골고루 들어가도록 루너부의 형상과 용량을 변경하여 왔으며 또 다른 예로는 표면의 조도를 개선하는 방법이 알려져 왔다.For example, the shape and capacity of the runner parts have been changed to evenly intake air into the runner on the engine cylinder including the intake-manifold. Another example is to improve the surface roughness. It has been known.
그리고 또 다른 개선장치로는 에어 클리너의 전, 후로 헬름홀츠(Helmholtz)의 공명원리(共鳴原理)를 이용하여 음량(音量)을 작게 레저네이터(Resonator)나 기계 및 전기적 진동을 억제시켜 주는 공진실(Resonance Chamber)과 VICS(Variable Inertia Charging System=가변흡기장치) 등을 통하여 공명과급 및 관성과급 효과를 이용하여 왔다.Another improvement device is the resonant chamber that suppresses resonators, mechanical and electrical vibrations by using Helmholtz's resonance principle before and after the air cleaner. Resonance chamber and VICS (Variable Inertia Charging System) have been used to resonate supercharge and inertial pay effect.
이밖에도 흡기계의 단면적을 엔진의 운전상황에 맞도록 가변절환하여 주므로서 흡입공기의 흡입작용에 따른 관내의 유동저항을 최소화하고 헤드포트(Headport)내에서 라디에이터와 냉각팬을 감싸고 있는 슈라우드(Shroud)를 설치하여 흡입된 공기와 혼합가스를 스월(Swirl)시켜 연소효과를 높혀 주는 기술들이 적용되어 왔다.In addition, by changing the cross-sectional area of the intake machine to match the operating conditions of the engine, the shroud surrounding the radiator and cooling fan in the headport is minimized by minimizing the flow resistance in the pipe due to the suction action of the intake air. The technology has been applied to increase the combustion effect by swirling the sucked air and the mixed gas by installing a.
그러나 이와 같은 기술에 의한 모든 장치들은 엔진룸내에 설치하기 위해서는 엔진룸의 내부 용적율(容積率)을 상당히 차지하는 문제점을 인해 최근에서와 같이 엔진이 대형화하는 추세에 비추어 볼 때 엔진룸을 설계하는데 많은 어려움을 수반하는 결점이 있어 왔다.However, due to the problem that all the devices based on this technique occupy a considerable internal volume ratio of the engine room to be installed in the engine room, it is difficult to design the engine room in view of the recent trend of larger engines. There have been drawbacks that accompany it.
본 발명에서는 상기와 같은 결점을 해결하기 위하여 엔진 실린더의 내부로 흡입되는 흡입공기에 대한 흡입효율을 엔진의 운전영역에서 효과적으로 증대시킴으로서 이루어지는 엔진의 연소효율증가에 의한 엔진의 출력향상과 배기가스의 저감효과를 얻을 수 있게 한 구성의 흡기효율 증가장치를 특징으로 한 것인바, 이하 첨부된 도면에 따라 본 발명을 상세히 설명하면 다음과 같다.In the present invention, in order to solve the above drawbacks, the output efficiency of the engine is reduced and the exhaust gas is reduced by increasing the combustion efficiency of the engine by effectively increasing the suction efficiency of the intake air sucked into the engine cylinder in the engine operating area. It is characterized by a device for increasing the intake efficiency of the configuration to achieve the effect, described in detail below the present invention according to the accompanying drawings.
제1도는 본 발명의 작용상태를 보인 실시예로서 (a)도는 저부하의 경우 엔진 실린더(1)의 인테이크 메니폴드에서 엔진 실린더(1)별로 흡입공기가 각각의 흡기밸브(2)(3)으로 공급되는 인테이크 메니폴드의 루너부(4)(5) 상에서 흡입공기(10)가 원주방향으로 강한 스윌을 일으킬 수 있도록 셔터 밸브(7)가 개방된 상태이고 (b)도는 상기의 셔터 밸브(7)가 폐쇄된 고부하의 경우 흡입공기(10)의 스윌 방향을 나타낸 것이다.1 is an embodiment showing the operating state of the present invention (a) in the intake manifold of the engine cylinder (1) in the case of low load intake air for each engine cylinder (1) to each intake valve (2) (3) The shutter valve 7 is opened so that the suction air 10 causes a strong slew in the circumferential direction on the runner portions 4 and 5 of the supplied intake manifold, and the shutter valve 7 shown in FIG. In the case of closed high load, it shows the slew direction of the intake air 10.
여기에서 설명되지 아니한 부호 6은 엔진피스톤, 8은 피스톤링을 각각 표시한다.Reference numeral 6, which is not described herein, denotes an engine piston, and 8, a piston ring, respectively.
상기와 같이 장착 구성된 셔터 밸브(7)는 본 발명 제2도의 도시에서 보는 바와 같이 엔진(1)의 상태를 알려주는 흡기온도센서(S1)와 엔진 rpm센서(S2), 스로틀 센서(S3), 냉각수온센서(S4), 속도센서(S5) 및 아이들 스위치(S/W)에 의해 E.C.U(11)로 입력정보를 연산처리하여 최적의 흡입공기(10)에 의한 스윌 효과가 일어날 수 있도록 상기의 셔터 밸브(7)를 상황에 맞도록 가변절환시켜 주는 전자제어식 솔레노이드 밸브(9)를 출력 제어되도록 한 것이다.The shutter valve 7 configured as described above has an intake air temperature sensor S 1 , an engine rpm sensor S 2 , and a throttle sensor S indicating the state of the engine 1 as shown in FIG. 2 . 3 ), the cooling water temperature sensor (S 4 ), the speed sensor (S 5 ) and the idle switch (S / W) to process the input information to the ECU (11) to achieve the slew effect by the optimal intake air (10) It is to control the output of the electronically controlled solenoid valve (9) to variably switch the shutter valve (7) in accordance with the situation to occur.
그러나 본 발명의 적용범위는 밸브수에 무관하여 셔터 밸브(7)는 엔진(1)의 각 상태에 따라 최적의 흡입공기(10)에 의해 스윌 효과가 발생될 수 있도록 연속적으로 제어작동이 가능하다.However, the scope of the present invention is irrespective of the number of valves, the shutter valve 7 can be continuously controlled so that the swivel effect can be generated by the optimum intake air 10 according to each state of the engine (1). .
특히 저부하의 경우는 원주방향의 스윌이 클수록 유리하고 고부하시는 관내 유동저항이 적을수록 유리한 이점을 제공한다.Particularly in the case of low load, the larger the slew in the circumferential direction, the more advantageous the lower the flow resistance in the tube under high load.
