본 발명은 내연기관의 공기유입시스템에 관한 것으로서, 상세하게는 과급기를 포함하는 내연기관의 공기유입시스템에 관한 것이다.The present invention relates to an air inlet system of an internal combustion engine, and more particularly, to an air inlet system of an internal combustion engine including a supercharger.

제 1도에 대해 설명한다면, 여기에는 내연기관의 동력으로 구동되는 과급기를 포함하고 있는 내연기관의 공기유입시스템이 도시되어 있다.Referring to FIG. 1, there is shown an air inlet system of an internal combustion engine including a supercharger driven by the power of the internal combustion engine.

상기 언급한 공기유입시스템은 공기여과기(10), 공기여과기(10)를 내연기관(12)의 공기유입구(12a)에 연결하는 공기유입파이프(11) 및 과급기(13)로 이루어진다. 과급기(13)는 공기여과기(10)와 기관(12) 사이에 배치되고 그리고 공기유입파이프(11)에 의해 공기여과기(10)와 기관(12)에 상호 연결된다. 공기유입파이프(11a)는 공기여과기(10)와 기관(12) 사이에 배치되어 과급기(13)를 우회한다. 따라서, 우회하는 공기유입파이프(11a)의 일단은 공기여과기(10)와 과급기(13)간에 배치된 공기유입파이프(11)에 연결되고, 우회하는 공기유입파이프(11a)의 타단은 과급기(13)와 기관(12)의 공기유입구(12a)간이 비치된 공기유입파이프(11)에 연결된다. 우회하는 공기유입파이프(11a)의 일단과 공기유입파이프(11)간의 접속은 3방향 밸브 또는 콕크(14)를 이용하므로써 성취된다.The above mentioned air inlet system consists of an air filter 10, an air inlet pipe 11 and a supercharger 13 connecting the air filter 10 to the air inlet 12a of the internal combustion engine 12. The supercharger 13 is arranged between the air filter 10 and the engine 12 and is interconnected to the air filter 10 and the engine 12 by an air inlet pipe 11. The air inlet pipe 11a is disposed between the air filter 10 and the engine 12 to bypass the supercharger 13. Therefore, one end of the bypass air inlet pipe 11a is connected to the air inlet pipe 11 disposed between the air filter 10 and the supercharger 13, and the other end of the bypassed air inlet pipe 11a is the supercharger 13. ) And the air inlet 12a of the engine 12 are connected to the air inlet pipe 11 provided. The connection between one end of the bypass air inlet pipe 11a and the air inlet pipe 11 is achieved by using a three-way valve or cock 14.

클러치기구(15)는 기관(12)에 요하는 출력에 따라 과급기(13)로의 해제 및 접속을 제어한다. 벨트는 기관(12)으로부터 동력을 클러치에 전달한다. 기관구동축(12b)는 벨트(16)을 구동하는 폴리(12c)에 기관동력을 전달한다.The clutch mechanism 15 controls the release and connection to the supercharger 13 in accordance with the output required by the engine 12. The belt transmits power from the engine 12 to the clutch. The engine drive shaft 12b transmits the engine power to the pulley 12c which drives the belt 16.

동작에 있어, 기관(12)의 출력수요량이 예정치와 같거나 그 이상일때, 공기여과기(10)를 통과하는 공기는 과급기(13)로 보내지고 그런다음 클러치기구(15)를 통해 기관(12)으로부터 과급기(13)에의 동력의 접속으로 인해 기관(12)의 공기유입구(12a)에 과급된다. 반면에, 기관(12)의 출력수요량이 예정치 보다 작을때, 공기여과기(10)를 통과하는 공기는 클러치기구(15)를 통해 기관(12)으로부터 과급기(13)로의 동력의 해제 및 3방향밸브(14)의 방향변경에 의해 우회하는 공기유입파이프(11a)를 통해 기관(12)의 공기유입구(12a)속으로 바로 보내진다.In operation, when the output demand of the engine 12 is equal to or greater than the predetermined value, the air passing through the air filter 10 is sent to the supercharger 13 and then through the clutch mechanism 15 to the engine 12. ) Is charged to the air inlet 12a of the engine 12 due to the connection of power to the supercharger 13. On the other hand, when the output demand of the engine 12 is smaller than the predetermined value, the air passing through the air filter 10 is released through the clutch mechanism 15 from the engine 12 to the turbocharger 13 and in three directions. Directly into the air inlet 12a of the engine 12 through the air inlet pipe 11a bypassed by the change of the direction of the valve (14).

그러나, 내연기관의 상기 언급한 공기유입시스템은 다음과 같은 문제점을 갖는다. 하나의 문제점은 기관(12)으로부터 공기유입시스템의 과급기(13)에 동력을 전달하기 위해 벨트(16)를 사용하기 때문에 자동차의 기관실에 배치된 장치들의 구성에 상당한 제한이 있다는 것이다. 다른 문제점은 기관(12)에 요하는 출력에 따라 과급기(13)에의 동력의 해제 및 접속을 제어하는 클러치기구(15)로 인한 내연기관(12)의 불필요한 토오크변동이 있다는 것이다.However, the above mentioned air inflow system of the internal combustion engine has the following problems. One problem is that the belt 16 is used to transfer power from the engine 12 to the supercharger 13 of the air inlet system, which imposes significant limitations on the configuration of the devices arranged in the engine room of the motor vehicle. Another problem is that there is an unnecessary torque fluctuation of the internal combustion engine 12 due to the clutch mechanism 15 which controls the release and connection of power to the supercharger 13 in accordance with the output required by the engine 12.

본 발명의 주목적은 클러치기구를 통해 과급기를 구동하는 벨트를 배제하여 자동차의 기관실내의 장치제약 및 공간제약을 감소시키는데 있다.The main object of the present invention is to reduce the device constraints and the space constraints in the engine compartment of an automobile by excluding the belt driving the supercharger through the clutch mechanism.

본 발명의 다른 목적은 기관(12)의 출력수요량에 따라 과급기에의 동력의 해제 및 접속을 제어하는 클러치기구로 인한 내연기관의 불필요한 토오크변동을 없애는데 있다.Another object of the present invention is to eliminate unnecessary torque fluctuations of an internal combustion engine due to a clutch mechanism that controls the release and connection of power to the supercharger in accordance with the output demand of the engine 12.

본 발명에 의한 내연기관의 공기유입시스템은 도관과 과급기를 포함한다. 도관은 내연기관의 공기유입구에 접속된다. 과급기는 도관중에 놓여진다.The air inlet system of the internal combustion engine according to the invention comprises a conduit and a supercharger. The conduit is connected to the air inlet of the internal combustion engine. The supercharger is placed in the conduit.

본 발명에 의하면, 과급기는 회전이 제어되는 모터에 의해 직접 구동된다.According to the invention, the supercharger is directly driven by a motor whose rotation is controlled.

제 2 도에는, 본 발명에 따른 내연기관의 공기유입시스템이 도시되어 있다. 제 1도에 대해 도시한 바와 같이 같은 구조는 같은 부호로 나타냈다.2 shows an air inlet system of an internal combustion engine according to the present invention. As shown with respect to FIG. 1, the same structure is denoted by the same reference numeral.

내연기관의 공기유입시스템은 공기여과기(10), 내연기관(12)의 공기유입구(12a)에 공기여과기(10)를 연결하는 공기유입파이프(11) 및 과급기(13)를 포함한다. 과급기(13)는 공기여과기(10)와 기관(12) 사이에 배치되어서 공기유입파이프(11)에 의해 공기여과기(10)와 기관(12)양쪽에 연결된다. 모터(131)는 과급기(13)에 부착되어 과급기(13)를 직접 구동한다.The air inlet system of the internal combustion engine includes an air filter 10, an air inlet pipe 11 connecting the air filter 10 to the air inlet 12a of the internal combustion engine 12, and a supercharger 13. The supercharger 13 is disposed between the air filter 10 and the engine 12 and is connected to both the air filter 10 and the engine 12 by the air inlet pipe 11. The motor 131 is attached to the turbocharger 13 to directly drive the turbocharger 13.

모터회전제어회로(132)는 각기 와이어에 의해 모터(131), 변환기(133) 및 교류발전기(17)에 연결된다. 모터회전제어회로(132)는 변환기(133)로부터 받아들인 신호에 따라 모터(131)의 회전을 제어하고 동시에 교류발전기(17)에 의해 발전된 교류전류를 직류전류로 바꾼다. 변환기(133)는 기관(12)에 요하는 출력을 전기적인 신호로와 마찬가지로 자동차의 가속기의 밟음 량을 변환하고 모터회전제어회로(132)에 전기적인 신호를 보낸다. 교류전류를 발생하는 교류발전기(17)는 기관(12)의 동력에 의한 벨트(18)를 통해 구동된다. 벨트(18)는, 기관(12)의 구동축(12b)에 부착된 풀리(12d)와, 교류발전기(17)의 축(17b)에 부착된 풀리(17a)에 맞물린다.The motor rotation control circuit 132 is connected to the motor 131, the converter 133, and the alternator 17 by wires, respectively. The motor rotation control circuit 132 controls the rotation of the motor 131 according to the signal received from the converter 133 and simultaneously converts the alternating current generated by the alternator 17 into a direct current. The converter 133 converts the stepped amount of the accelerator of the vehicle and sends an electric signal to the motor rotation control circuit 132 as the electric signal output to the engine 12 as an electric signal. The alternator 17 which generates the alternating current is driven through the belt 18 by the power of the engine 12. The belt 18 meshes with the pulley 12d attached to the drive shaft 12b of the engine 12 and the pulley 17a attached to the shaft 17b of the alternator 17.

동작중, 자동차의 가속기와 요구된 기관(12)의 출력에 따라 밟아졌을때, 가속기의 밟은량은 적절한 전기신호를 변환되고, 그 적절한 전기적신호는 모터회전제어회로(132)에 보내진다. 모터회전제어회로(132)는 변환기(133)로부터의 전기적인 신호에 따라 모터(131)의 회전을 제어한다. 그 결과, 모터(131)는 기관(12)의 출력수요량에 따라 바로 과급기(13)를 구동시키기 위해 회전한다.During operation, when stepped on in accordance with the accelerator of the automobile and the output of the required engine 12, the stepped amount of the accelerator converts an appropriate electrical signal, which is sent to the motor rotation control circuit 132. The motor rotation control circuit 132 controls the rotation of the motor 131 according to the electrical signal from the converter 133. As a result, the motor 131 immediately rotates to drive the supercharger 13 in accordance with the output demand of the engine 12.

제 3 도에는, 본 발명의 다른 구현예에 따른 내연기관의 공기유입시스템이 도시되어 있다. 마찬가지로, 동일구조에 대해서는 동일부호로 나타내었으며 그의 설명은 생략했다.3 shows an air inlet system of an internal combustion engine according to another embodiment of the invention. Likewise, the same structure is denoted by the same reference numerals and description thereof is omitted.

우회하는 공기유입파이프(11b)가 과급기(13)를 우회하기 위하여 공기여과기(10)와 기관(12) 사이에 배치된다. 따라서, 우회하는 공기유입파이프(11b)의 일단은 공기여과기(10)와 과급기(13) 사이에 배치된 공기유입파이프(11)에 연결되고, 공기유입파이프(11b)의 타단은 과급기(13)와 내연기관(12)의 공기유입구(12a) 사이에 배치된 공기유입파이프(11)에 연결된다. 플랩밸브(19)가 우회하는 공기유입파이프(11b) 및 과급기(13)와 내연기관(12)의 공기유입구(12a) 사이에 배치된 공기유입파이프(11)에 접합점에 배치된다.The bypass air inlet pipe 11b is disposed between the air filter 10 and the engine 12 to bypass the supercharger 13. Therefore, one end of the bypass air inlet pipe 11b is connected to the air inlet pipe 11 disposed between the air filter 10 and the supercharger 13, and the other end of the air inlet pipe 11b is the supercharger 13. And an air inlet pipe 11 disposed between the air inlet 12a of the internal combustion engine 12. The flap valve 19 is disposed at the junction point between the air inlet pipe 11b and the air inlet pipe 11 disposed between the supercharger 13 and the air inlet 12a of the internal combustion engine 12.

동작중, 변환기(133)로부터의 전기적인 신호가 예정치와 같거나 클때, 즉, 기관(12)의 출력수요량이 예정치와 같거나 클때, 모터(131)는 모터회전제어회로(132)의 제어하에 바로 과급기(13)를 구동시키기 위해 회전한다. 뒤이어, 우회하는 공기유입파이프(11b)의 타단은 과급기(13)로부터 송풍된 압축공기에 의해 들려 올려지는 플랩밸브(19)에 의해 폐쇄된다. 따라서, 공기여과기(10)를 통과하는 공기는 과급기(13)로 보내져서 우회하는 공기유입파이프(11b)에 의해 통과됨이 없이 기관(12)의 공기유입구(12a)에 과급되어지게 된다.During operation, when the electrical signal from the transducer 133 is equal to or greater than the predetermined value, that is, when the output demand of the engine 12 is equal to or greater than the predetermined value, the motor 131 is connected to the motor rotation control circuit 132. It rotates to drive the supercharger 13 directly under control. Subsequently, the other end of the bypass air inlet pipe 11b is closed by the flap valve 19 lifted by the compressed air blown from the supercharger 13. Therefore, the air passing through the air filter 10 is supercharged at the air inlet 12a of the engine 12 without being passed by the air inlet pipe 11b which is sent to the supercharger 13 and bypassed.

반면에, 변환기(133)로부터의 전기적인 신호가 예정치 보다 작을때, 즉, 기관(12)의 출력수요량이 예정치보다 작을때, 과급기(13)는 모터회전제어회로(132)에 의해 정지되는 모터(131)로 인해 그의 동작은 정지한다. 뒤이어서, 우회하는 공기유입파이프(11b)의 타단은 자체 중량에 의해 낙하하는 플랩밸브(19)로 인해 개방되어진다. 따라서, 공기여과기(10)를 통과하는 공기는 우회하는 공기유입파이프(11b)를 통해 기관(12)의 공기유입구(12a)속으로 바로 들어간다.On the other hand, when the electrical signal from the converter 133 is smaller than the predetermined value, that is, when the output demand of the engine 12 is smaller than the predetermined value, the supercharger 13 is stopped by the motor rotation control circuit 132. The motor 131 stops its operation. Subsequently, the other end of the bypassing air inlet pipe 11b is opened due to the flap valve 19 falling by its own weight. Therefore, the air passing through the air filter 10 directly enters the air inlet 12a of the engine 12 through the bypass air inlet pipe 11b.
