Abstract
자동차 엔진의 흡기 조절장치에 관한 것으로서, 특히 엔진의 전속도 구간에서 흡입 공기의 스월 유동이 발생되도록 하므로서, 혼합기의 형성 및 연소성을 향상시키고, 엔진의 출력을 향상시킬 수 있도록 한다.The present invention relates to an intake control device for an automotive engine, and in particular, to cause a swirl flow of intake air in the full speed section of the engine, thereby improving the formation and combustibility of the mixer and improving the output of the engine.
이를 위하여 본 고안의 흡기 조절장치는 스월 컨트롤밸브(6)의 작동실(6a)과 연통된 연료파이프(9)와, 그 연료파이프의 리턴라인(10)에 설치되고 전자제어유닛에 의해 제어되어 상기 리턴라인을 개폐하는 솔레노이드 밸브(11)를 포함하여 구성된다. 이러한 구성에 따라, 상기 솔레노이드 밸브에 의해 리턴라인이 폐쇄될 경우, 연료파이프를 통해 작동실로 공급된 연료의 압력에 의해 흡기 매니폴드(2)에 설치된 밸브체(8)가 개폐조절된다. 또한, 상기 솔레노이드 밸브의 개방시 작동실의 연료압이 해제되고, 스월 컨트롤 밸브의 작동이 중지된다.To this end, the intake control device of the present invention is installed in the fuel pipe 9 in communication with the operation chamber 6a of the swirl control valve 6 and in the return line 10 of the fuel pipe and controlled by the electronic control unit. It comprises a solenoid valve 11 for opening and closing the return line. According to this configuration, when the return line is closed by the solenoid valve, the valve body 8 provided in the intake manifold 2 is opened and closed by the pressure of the fuel supplied to the operation chamber through the fuel pipe. In addition, the fuel pressure of the operating chamber is released when the solenoid valve is opened, and the swirl control valve is stopped.
따라서, 상기한 솔레노이드 밸브는 흡기 부압에 관계없이, 연료 압력에 의해 엔진의 전속도 영역에서 모두 작동이 가능하게 된다.Therefore, the solenoid valve described above can be operated in the full speed region of the engine by the fuel pressure irrespective of the intake negative pressure.
Description
본 고안은 자동차 엔진의 흡기 조절장치에 관한 것으로서, 특히 스월 컨트롤밸브(SCV : swirl control valve)의 개폐가 연료의 압력에 의해 작동되도록 하므로서, 그 스월 컨트롤밸브의 작동 구간을 엔진의 전속도 영역으로 확대할 수 있도록 한 자동차 엔진의 흡기 조절장치에 관한 것이다.The present invention relates to an intake control device of an automobile engine, and in particular, the opening and closing of a swirl control valve (SCV) is operated by the pressure of the fuel, so that the operating section of the swirl control valve is moved to the full speed range of the engine. It relates to an intake regulator of an automobile engine that can be enlarged.
주지된 바와 같이, 내연기관을 대표하는 자동차 엔진은 통상 4사이클로 이루어지며, 실린더 내에서 승가되는 피스톤의 왕복 작용에 의해 부압을 형성하여 외부의 공기를 흡입하고, 상기 공기가 흡입된 연소실로 연료를 분사하여 적정의 혼합기를 만든 후, 이를 점화시켜 엔진을 구동한다.As is well known, an automobile engine representing an internal combustion engine is usually composed of four cycles, and generates negative pressure by reciprocating action of a piston that is elevated in a cylinder to suck in outside air, and to supply fuel to the combustion chamber where the air is sucked. After injection, a suitable mixer is produced, which is then ignited to drive the engine.
여기서, 외부의 신선함과 공기는 피스톤이 흡입 행정을 위해 하강할 때 1회 개방되는 흡기 밸브가 열려짐으로써, 흡기계를 통해 유입된다.Here, external freshness and air are introduced through the intake machine by opening the intake valve, which is opened once when the piston descends for the intake stroke.
이러한 흡기계의 일반적인 구성이 도 1 에 상세하게 도시되어 있다.The general configuration of such an intake machine is shown in detail in FIG. 1.
도면에서의 설명 부호 (1)은 엔진 전체를 지칭한다. 엔진(1)은 실린더를 따라 상, 하 방향으로 왕복운동되는 피스톤은 흡기 밸브의 개방시 부압을 발생시켜 외부의 공기를 유입한다.Reference numeral 1 in the drawings refers to the entire engine. The engine 1 is a piston reciprocating in the up and down direction along the cylinder generates negative pressure when the intake valve is opened to introduce external air.
이를 위해, 상기 공기의 통로인 흡기관(4)에는 먼지나 이물질을 여과하는 에어 클리너(5)가 설치되고, 상기 공기를 흡기 매니폴드(2)를 통해 실린더의 각 연소실로 분배하는 서지탱크(3)가 설치된다.To this end, an air cleaner 5 for filtering dust or foreign matter is installed in the intake pipe 4, which is the passage of air, and a surge tank for distributing the air to each combustion chamber of the cylinder through the intake manifold 2 ( 3) is installed.
또한, 상기한 흡기관(4)에는 연소실로 유입되는 공기의 양을 적절히 조절하기 위한 드로틀 밸브가 설치된다.In addition, the intake pipe 4 is provided with a throttle valve for appropriately adjusting the amount of air flowing into the combustion chamber.
드로틀 밸브는 공기 통로인 드로틀 바디의 내측에, 가속페달에 의해 연동되어 회전되도록 설치된다.The throttle valve is installed inside the throttle body, which is an air passage, so as to be interlocked by an accelerator pedal to rotate.
이러한 구성에 따라, 드라이버의 가속페달 조작에 의해 드로틀 밸브가 개방되면, 에어 클리너(5)를 거쳐 청정화 된 공기가 서지탱크(3)로 공급되어 저장되고, 피스톤이 하강되고 흡기 밸브가 개방되어 실린더의 내부에 부압이 생성되므로서, 엔진의 연소실로 공급되어 연료와 함께 압축 및 연소된다.According to this configuration, when the throttle valve is opened by the accelerator pedal operation of the driver, the purified air is supplied to and stored in the surge tank 3 through the air cleaner 5, the piston is lowered and the intake valve is opened to open the cylinder. As the negative pressure is generated inside the fuel cell, it is supplied to the combustion chamber of the engine and compressed and combusted with the fuel.
한편, 상기한 흡기 매니폴드(2)에는 연소실로 유입되는 공기에 강한 스월 유동을 발생시켜, 희박 연소를 가능토록 하는 스월 컨트롤밸브(6)가 설치된다.On the other hand, the intake manifold 2 is provided with a swirl control valve 6 which generates strong swirl flow in the air flowing into the combustion chamber and enables lean combustion.
이 스월 컨트롤밸브(6)는 서지탱크(3)에 관로(7)로서 연통되어, 흡기 부압에 의해 동작되므로서, 그에 연동되는 밸브체(8)의 개폐를 조절하여, 연소실로 공급되는 흡입 공기에 강한 스월 유동을 발생시킨다.The swirl control valve 6 communicates with the surge tank 3 as the conduit 7 and is operated by intake negative pressure, thereby controlling the opening and closing of the valve body 8 linked thereto, and supplying the intake air to the combustion chamber. Generates a strong swirl flow.
종래 기술에서 설명된 자동차 엔진의 흡기계에 있어서, 스월 컨트롤밸브는 서지탱크의 내부에 발생되는 흡입 공기의 부압을 이용하여 동작된다.In the intake system of the automobile engine described in the prior art, the swirl control valve is operated by using the negative pressure of the intake air generated inside the surge tank.
그러나 상기한 흡입 공기의 부압은 엔진의 운전 속도가 증가됨에 따라 점차로 작어져, 엔진의 고속 운전시 스월 컨트롤밸브의 작동이 어렵게 되는 문제점을 초래한다.However, the negative pressure of the intake air gradually decreases as the operating speed of the engine increases, which causes a problem that the operation of the swirl control valve becomes difficult during high speed operation of the engine.
즉, 종래에는 스월 컨트롤밸브의 작동 구간이 엔진의 저속 및 중속 구간에 한정되며, 엔진의 고속 운전시에는 연소실로 공급되는 흡입 공기에 스월 유동이 발생되지 못하여, 혼합기의 연소성 및 엔진의 출력을 저하시키게 된다.That is, in the related art, the operation section of the swirl control valve is limited to the low and medium speed sections of the engine, and during the high speed operation of the engine, swirl flow does not occur in the intake air supplied to the combustion chamber, thereby reducing the combustibility of the mixer and the output of the engine. Let's go.
본 고안은 상술된 종래 기술의 문제점을 해소하기 위한 목적에서 제안된 것으로서, 특히 엔진의 고속 운전시 스월 컨트롤밸브의 작동을 가능토록 하여, 엔진의 전속도 영역에서 흡입 공기의 스월 유동이 발생되도록 하고, 혼합기의 연소성 및 엔진의 출력이 향상되도록 한 자동차 엔진의 흡기 조절장치를 제공한다.The present invention has been proposed for the purpose of solving the above-mentioned problems of the prior art, and in particular, enabling the operation of the swirl control valve during high speed operation of the engine, so that the swirl flow of intake air is generated in the full speed region of the engine In addition, the present invention provides an intake control device for an automobile engine to improve the combustibility of the mixer and the output of the engine.

이하, 본 고안을 실현하기 위한 바람직한 실시예를 첨부 도면에 의거하여 보다 상세하게 설명한다.Hereinafter, preferred embodiments for realizing the present invention will be described in more detail with reference to the accompanying drawings.
도 2 는 본 고안에 의한 자동차 엔진의 흡기 조절장치를 도시한 전체 구성도이다.Figure 2 is an overall configuration diagram showing an intake control device of an automobile engine according to the present invention.
본 실시예를 설명함에 있어, 종래 기술에서 인용된 도면과 동일한 본 실시예의 구성에 대해서는 동일한 부호를 사용하고 있으며, 설명의 명료성을 위해 다시 설명하지 않는다.In describing the present embodiment, the same reference numerals are used for the configuration of the present embodiment, which is the same as the drawings cited in the prior art, and will not be described again for clarity.
도면에서의 설명 부호 (3)은 서지탱크를 지칭한다.Reference numeral 3 in the drawings refers to the surge tank.
서지탱크(3)에는 가속페달과 연동되어 개폐되는 드로틀 밸브의 개폐정도에 따라, 에어 클리너(5)와 흡기관(4)을 통해 청정된 공기가 유입되고, 그 공기가 일시적으로 저장된다.According to the opening and closing degree of the throttle valve which is opened and closed in conjunction with the accelerator pedal, the surge tank 3 receives clean air through the air cleaner 5 and the intake pipe 4, and the air is temporarily stored.
다시, 서지탱크(3)에 임시 저장된 공기는 엔진(1)의 실린더를 따라 상, 하 방향으로 왕복운동되는 피스톤의 부압에 의해, 흡기 밸브의 개방시, 흡기 매니폴드(2)를 통해 각 실린더의 연소실로 분배된다.Again, the air temporarily stored in the surge tank 3 is caused by the negative pressure of the piston reciprocating in the up and down direction along the cylinder of the engine 1, and upon opening of the intake valve, each cylinder through the intake manifold 2 Is distributed to the combustion chamber.
이와 같은 구성들을 포함하는 자동차 엔진의 흡기계에 있어서, 본 실시예의 흡기 조절장치는 각 실린더의 연소실로 흡입 공기를 공급하는 흡기 매니폴드(2)에 설치되는 밸브체(8)와, 그 밸브체(8)를 개폐 동작시키는 스월 컨트롤밸브(6)를 포함한다.In the intake system of an automobile engine including such configurations, the intake control device of the present embodiment includes a valve element 8 provided in an intake manifold 2 for supplying intake air to the combustion chamber of each cylinder, and the valve element. (8) and a swirl control valve (6) for opening and closing operation.
밸브체(8)는 스월 컨트롤밸브(6)의 피스톤(6b)에 연결되고, 그 피스톤(6b)은 리턴 스프링(6c)에 의해 탄지된다.The valve body 8 is connected to the piston 6b of the swirl control valve 6, and the piston 6b is supported by the return spring 6c.
여기서, 스월 컨트롤밸브(6)의 작동실(6a)에는 연료파이프(9)가 연결된다. 또한, 그 연료파이프(9)의 리턴라인(10)에는 전자제어유닛(ECU)에 의해 제어되어 상기 리턴라인(10)을 개폐하는 솔레노이드 밸브(11)가 설치된다.Here, the fuel pipe 9 is connected to the operation chamber 6a of the swirl control valve 6. In addition, a solenoid valve 11, which is controlled by an electronic control unit ECU and opens and closes the return line 10, is installed in the return line 10 of the fuel pipe 9.
이상에서 설명된 본 실시예의 구성에 의거하여, 상기한 ECU에 의해 제어되는 솔레노이드 밸브(11)가 리턴라인(10)을 폐쇄하면, 연료파이프(9)를 통해 공급된 연료가 스월 컨트롤밸브(6)의 작동실(6a)로 보내져 연료압을 발생시킨다.Based on the configuration of this embodiment described above, when the solenoid valve 11 controlled by the ECU closes the return line 10, the fuel supplied through the fuel pipe 9 is swirl control valve 6. Is sent to the operating chamber 6a to generate fuel pressure.
이어서 상기 연료압은 스월 컨트롤밸브(6)의 피스톤(6b)을 도면의 우측 방향으로 밀어, 그에 연동되는 밸브체(8)를 개폐시키므로서, 흡기 매니폴드(2)를 통해 연소실로 공급되는 흡입 공기에 강한 스월 유동을 발생시킨다.The fuel pressure is then supplied to the combustion chamber through the intake manifold 2 while pushing the piston 6b of the swirl control valve 6 in the right direction of the drawing to open and close the valve body 8 linked thereto. Generates a strong swirl flow in the air.
또한, 상기 솔레노이드 밸브(11)의 개방시 작동실(6a)의 연료압이 해제되고, 스월 컨트롤밸브(6)는 그 작동을 중지한다.In addition, when the solenoid valve 11 is opened, the fuel pressure of the operation chamber 6a is released, and the swirl control valve 6 stops its operation.
이상에서 설명된 구성 및 작용을 통하여 알 수 있는 바와 같이, 본 고안에 의한 자동차 엔진의 흡기 조절장치는 종래 기술의 문제점을 실질적으로 해소하게 된다.As can be seen through the configuration and operation described above, the intake control device for an automobile engine according to the present invention substantially solves the problems of the prior art.
즉, 본 고안에 의한 스월 컨트롤밸브는 연료의 압력에 의해 동작되므로서, 엔진의 저, 중속 뿐 아니라 고속 구간에서도 원활하게 동작되는 효과를 얻을 수 있다.In other words, the swirl control valve according to the present invention is operated by the pressure of the fuel, it is possible to obtain the effect of operating smoothly in the low and medium speed of the engine as well as the high speed section.
따라서, 본 고안에 의하면 엔진의 전속도 영역에서 흡입 공기에 강한 스월 유동이 발생되며, 그에 따라 혼합기의 형성 및 연소성이 향상되고, 결과적으로 엔진의 출력이 향상되는 효과를 얻을 수 있다.Therefore, according to the present invention, a strong swirl flow is generated in the intake air in the full speed region of the engine, thereby improving the formation and combustibility of the mixer, and consequently, the output of the engine can be obtained.
또한, 본 고안에 의하면 엔진의 희박 연소가 실현되는 효과도 얻을 수 있다.In addition, according to the present invention, the effect that lean combustion of the engine is realized can also be obtained.
한편, 본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 실용신안등록 청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.On the other hand, the present invention is not limited to the above-described specific preferred embodiment, any person having ordinary knowledge in the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the utility model registration claims Modifications may be made.
