본 고안은 인렛매니폴드의 보조공기 공급장치, 더욱 상세히는 고속주행시에 제4 매니폴드에 보조공기를 공급하여 흡기량 부족으로 인한 엔진성능의 저하를 방지하게 된 것이다.The present invention is to supply the auxiliary air to the inlet manifold auxiliary air supply, more specifically to the fourth manifold at high speed to prevent the deterioration of engine performance due to lack of intake air.
일반적으로 서지탱크에 유입된 공기는 제1∼4 인렛매니폴드를 통해 각각 해당 실린더에 공급되도록 구성되어 있는데, 상기 서지탱크에 공기를 도입하는 흡입구는 제1 인렛매니폴드 쪽으로 편향설치되어 있으므로, 엔진의 저속가동시에는 각 인렛매니폴드를 통합 공기공급량이 비교적 균일하나, 엔진의 고속가동시에는 흡입구와 가장 멀리 위치한 제4 인렛매니폴드 측으로의 공기공급량이 상대적으로 감소됨은 주지와 같다.In general, the air introduced into the surge tank is configured to be supplied to the respective cylinders through the first to fourth inlet manifolds, and the inlet port for introducing air to the surge tank is biased toward the first inlet manifold, so that the engine While the inlet manifold has a relatively uniform integrated air supply at low speed operation, the air supply to the fourth inlet manifold, which is farthest from the inlet, is relatively reduced at high speed operation of the engine.
이러한 흡기량의 불균일은 엔진의 노킹과 진동을 유발시킴으로서 각 구성부품의 조기파손, 손상 및 엔진의 출력을 저하시키는 근본 요인을 제공하게 되며, 따라서 최우선적인 개선이 요구된다.This non-uniformity of air intake causes the engine to knock and vibrate, thereby providing fundamental factors that prematurely damage, damage, and lower the engine output of each component, and therefore, a top priority improvement is required.
본 고안은 상기한 문제점을 해소시킬 수 있도록 엔진가동속도에 제한되지 않고 균일한 공기공급 상태를 유지할 수 있는 인렛매니폴드의 보조 공기 공급장치를 제공하기 위한 것으로, 특히 제4 인렛매니폴드의 상대적인 공기공급량 차이를 엔진가동 속도에 따라 보상해 주도록 하였다.The present invention is to provide an auxiliary air supply device of the inlet manifold that can maintain a uniform air supply state without being limited to the engine operating speed to solve the above problems, in particular the relative air of the fourth inlet manifold The difference in supply is compensated by the engine running speed.
이를위해 본 고안에서 실린더헤드 내부에 구동기구를 설치하여 설정된 이상으로 엔진이 가속가동할 경우 상기 구동기구에 보조공기통로가 개방됨으로써 제4 인렛매니폴드로 공급되는 공기량이 증가되게 하였다.To this end, in the present invention, when the engine is accelerated to a predetermined level by installing a drive mechanism inside the cylinder head, an auxiliary air passage is opened to the drive mechanism to increase the amount of air supplied to the fourth inlet manifold.
이하에서 상기 본 고안의 양호한 실시예를 첨부도면에 의해 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail by the accompanying drawings.
제1도는 본 고안 보조공기 공급장치의 설치상태를 나타내었고, 제2도는 그 구성을 개념적으로 도시한 것으로, 실린더헤드(1)의 내부에는 솔레노이드밸브(2)에 의해 선택개폐되는 오일통로(11)가 형성되어 있으며, 상기 솔레노이드밸브(2)는 설정된 기준RPM(예를들면 3,000RPM)보다 엔진이 고속가동될 경우 엔진제어부(E.C.U :3)의 신호에 의해 오일통로(11)를 폐쇄하도록 구성된다.Figure 1 shows the installation state of the auxiliary air supply device of the present invention, Figure 2 conceptually shows the configuration, the oil passage 11 which is selectively opened and closed by the solenoid valve (2) inside the cylinder head (1) Is formed, and the solenoid valve 2 is configured to close the oil passage 11 by the signal of the engine control unit (ECU: 3) when the engine is driven at a higher speed than the set reference RPM (for example, 3,000 RPM). do.
또한 상기 오일통로(11)의 일측에는 제한턱(12)을 포함하는 작동실(13)이 연통형성되어 구동기구(4)가 수납설치 되는데, 상기 구동기구(4)는 작동실(13)에 고정된 키이(5)와, 상기 키이(5)에 안내되는 안내홈(61)이 형성되어 오일통로(11)의 유압에 의해 작동실(13)내에서 미끄럼 왕복 이동하며 그 내부의 수납공간(62) 외벽에는 헬리컬기어부(63)를 형성시킨 피스톤(6)과, 상기 피스톤(6)의 왕복이동에 의해 정역구동하도록 헬리컬기어부(63)에 대응치합 설치되며 그 구동축(71)에는 구동기어(72)를 형성시킨 헬리컬기어봉(7)과, 상기 수납공간(62)내에 탄입설치되어 피스톤(6)에 인장복귀력을 부여하는 탄성부재(8)와, 상기 구동기어(72)와 치합하는 피동기어(91)의 피동축(92) 끝단에 설치되어 제4 인렛매니폴드(M)와 연통된 보조공기통로(10)를 개폐시키는 밸브(9)로 구성된다.In addition, one side of the oil passage 11 is formed with the operating chamber 13 including the limiting jaw 12 is connected to the drive mechanism 4 is installed, the drive mechanism 4 is in the operating chamber 13 The fixed key 5 and the guide groove 61 guided to the key 5 are formed to slide reciprocally in the operating chamber 13 by the hydraulic pressure of the oil passage 11, and the storage space therein ( 62) A piston 6 having a helical gear portion 63 formed on the outer wall thereof and a helical gear portion 63 corresponding to the helical gear portion 63 are operated so as to be driven forward and backward by the reciprocating movement of the piston 6, and the drive shaft 71 is driven. A helical gear rod 7 having a gear 72 formed therein, an elastic member 8 which is installed in the storage space 62 to impart a tensile return force to the piston 6, and the drive gear 72 and teeth It is composed of a valve (9) installed at the end of the driven shaft (92) of the driven gear (91) to open and close the auxiliary air passage (10) in communication with the fourth inlet manifold (M). .
도면중 미설명부호(64)는 유압수용부이고, (S)는 서지탱크이다.In the figure, reference numeral 64 is a hydraulic accommodating part, and S is a surge tank.
이와같은 구성의 본 고안은 엔진이 저속가동될 경우에는 솔레노이드밸브(2)가 오일통로(11)를 개방시킨 상태가 되며, 피스톤(6)은 탄성부재(8)의 가압인장력에 의해 제한턱(12)에 접촉된 상태로서 밸브(9)가 보조 공기통로(10)를 폐쇄상태로 유지시키게 된다.The present invention of such a configuration is that when the engine is running at a low speed, the solenoid valve 2 is in a state in which the oil passage 11 is opened, and the piston 6 is limited by the pressure pull force of the elastic member 8 ( The valve 9 keeps the auxiliary air passage 10 closed as it is in contact with 12).
그런데, 엔진이 고속가동될 경우에는 제4 인렛매니폴드(M)에 공급되는 공기량이 상대적으로 작으므로 이때에는 보조공기통로(10)를 개방시켜야 하는데, 이를위해 엔진제어부(3)는 미리설정된 RPM 보다 엔진이 고속 가동될 경우 솔레노이드밸브(2)를 온시킴으로써 솔레노이드밸브(2)는 오일통로(11)를 폐쇄시키게 된다.However, when the engine is running at high speed, the amount of air supplied to the fourth inlet manifold (M) is relatively small. At this time, the auxiliary air passage 10 should be opened. For this purpose, the engine control unit 3 sets a predetermined RPM. When the engine is running at a higher speed, the solenoid valve 2 is closed by turning on the solenoid valve 2.
이 경우에 오일통로(11) 내부는 밀폐되어 유압은 피스톤(6)의 유압수용부(64)에도 작용하게 되며, 이에따라 피스톤(6)은 그 안내홈(61)이 키이(5)를 따라 회동방지된 상태로서 도면상 우측으로 직선이동하게 된다.In this case, the inside of the oil passage 11 is sealed so that the hydraulic pressure acts on the hydraulic receiving portion 64 of the piston 6. Accordingly, the piston 6 has its guide groove 61 rotated along the key 5. As a prevented state, linear movement is made to the right side of the drawing.
상기한 피스톤(6)의 직선이동시에 그 수납공간(62) 내면의 헬리컬기어부(63)에 치합설치된 헬리컬기어봉(7)은 헬리컬기어의 경사각에 해당하는 회동이 유발되며, 따라서 구동기어(72)와 치합된 피동기어(91)도 회동하게 되므로 밸브(9)는 보조공기통로(10)를 개방시키게 된다.The helical gear rod 7 meshed with the helical gear part 63 on the inner surface of the storage space 62 causes the rotation corresponding to the inclination angle of the helical gear during the linear movement of the piston 6, and thus the driving gear 72 ) And the driven gear 91 engaged with () also rotates so that the valve (9) opens the auxiliary air passage (10).
여기에서 상기 헬리컬기어봉(7)의 회전은 밸브(9)가 90°회전(개폐)될 수 있는 범위내에서 이루어져야 하며, 밸브(9)의 개방시에 제 1∼3인렛매니폴드 보다 상대적으로 적은 공기가 공급되는 제4 인렛매니폴드(M)는 보조공기통로(10)로부터 공급되는 보조공기에 의해 원활한 공기 공급이 이루어지게 된다.In this case, the rotation of the helical gear rod 7 should be made within a range in which the valve 9 can be rotated (opened and closed) by 90 °, and relatively less than the first to third inlet manifolds when the valve 9 is opened. The fourth inlet manifold M to which air is supplied is smoothly supplied by the auxiliary air supplied from the auxiliary air passage 10.
한편, 엔진이 다시 저속가동될 경우에는 엔진제어부(3)에 의해 솔레노이드밸브(2)가 오일통로(11)를 개방시키게 되고, 유압의 해지에 의해 피스톤(6)은 탄성부재(8)의 압축복귀력으로 원위치로 복귀되며, 이와동시에 헬리컬기어봉(7)도 밸브(9)가 보조공기통로(10)를 폐쇄시키도록 초기의 상태로 회동된다.On the other hand, when the engine is operated at low speed again, the solenoid valve 2 opens the oil passage 11 by the engine control unit 3, and the piston 6 is compressed by the elastic member 8 by the release of hydraulic pressure. The return force is returned to its original position, and at the same time, the helical gear rod 7 is also rotated to an initial state so that the valve 9 closes the auxiliary air passage 10.
이와같이 본 고안은 엔진의 가동속도에 따라 제4 인렛매니폴드(M)에 보조공기가 보충되어 공급공기의 불균형에 기인하는 엔진의 노킹과 진동이 해소되며, 이에따라 엔진의 출력향상과 구성부품의 수명이 연장되므로 승차감과 차내정숙성, 사용자의 제품신뢰도를 대폭 향상시킬 수 있는 등의 광범위한 효과가 있다.As such, the present invention supplements auxiliary air to the fourth inlet manifold (M) according to the operating speed of the engine, thereby eliminating knocking and vibration of the engine caused by unbalanced supply air, thereby improving the output of the engine and the life of the components. This extension has a wide range of effects, such as significantly improved ride comfort, in-car quietness, and user reliability.
