일반적으로 열기관이란 열에너지를 기계적인 일로 바꾸는 장치이며 이 열에너지를 기계적인 일로 바꾸기 위해 그 매체(媒體)로 작동 물질이 필요하다. 이런 작동 물질에 열에너지를 공급하는 방식에 따라 내연기관과 외연기관으로 나눈다.In general, a heat engine is a device that converts thermal energy into mechanical work and requires a working material as a medium to convert the thermal energy into mechanical work. It is divided into internal combustion engine and external combustion engine according to the method of supplying thermal energy to these working materials.
이러한 외연기관은 보일러나 원자로와 같이 기관의 외부에서 발생한 열에너지를 절연벽을 통해 작동 물질에 가하는 것이며, 내연기관은 기관의 내부에서 연소가 이루어지며 혼합기 자체가 보유한 화학적 에너지를 연소에 의해 열에너지로 바꾸어 그 연소가스가 팽창할 때의 일을 직접 이용한 것으로 이에 속하는 기관으로는 피스톤 왕복형 기관, 로터리 기관, 가스터어빈, 제트기관 등이 있다.Such an external combustion engine applies thermal energy generated from the outside of the engine, such as a boiler or a reactor, to the working material through an insulating wall.The internal combustion engine burns inside the engine and converts the chemical energy of the mixer itself into thermal energy by combustion. When the combustion gas is expanded, the engine is used directly, and the engines belonging to it include a piston reciprocating engine, a rotary engine, a gas turbine, and a jet engine.
상기한 내연기관은 작동방식, 연소방식, 점화 또는 착화방식, 연료의 종류 및 공급방식, 냉각방식, 밸브 배치에 따른 분류 및 실린더수 및 배치에 의해 분류한다.The internal combustion engine is classified by the operating method, the combustion method, the ignition or ignition method, the type and supply method of the fuel, the cooling method, the classification according to the valve arrangement, and the number and arrangement of cylinders.
이 경우 기관을 작동시키기 위해서 흡/배기 시스템에 의해 실린더 내에 혼합기를 흡입하고 흡입된 혼합기를 연소시킨 후 그 배기가스를 외부로 배출시키게 된다.In this case, in order to operate the engine, the intake / exhaust system inhales the mixer in the cylinder, burns the sucked mixer, and exhausts the exhaust gas to the outside.
상기 흡기 시스템은 레조넌스 챔버와, 흡기 공기중의 먼지 등을 제거하는 공기 청정기와, 초우크 밸브와, 각 실린더에 혼합기를 분배하는 흡기 매니폴드와 스로틀 밸브 사이에 설치되어 흡기계통에 흡기 맥동이 발생하지 않도록 하는 서어지 탱크 등으로 구성되어 있으며, 배기 시스템은 각 실린더에서 형성된 배기가스를 모으는 배기 매니폴드와, 상기 배기 매니폴드에 모여진 배기가스를 배출시키는 배기관과, 캐털릭컨버터, 소음기 등으로 구성되어 있다.The intake system is provided between the resonance chamber, an air purifier for removing dust in the intake air, a choke valve, an intake manifold for distributing the mixer to each cylinder, and a throttle valve, to provide intake pulsation in the intake cylinder. The exhaust system includes an exhaust manifold for collecting exhaust gas formed in each cylinder, an exhaust pipe for exhausting the exhaust gas collected in the exhaust manifold, a catalytic converter, a silencer, and the like. Consists of.

이에 본 고안은 차량의 주행상태에 따라, 즉 고속 주행상태일 때 공기의 양을 증대시켜 흡기 효율을 높이며 저속 주행시 흡기량을 줄여 연비를 줄일 수 있는 차속에 따른 가변흡기 시스템을 제공하는데 그 목적이 있다.Therefore, the present invention aims to provide a variable intake system according to the vehicle speed that can reduce fuel consumption by increasing the amount of air in a high speed driving state, that is, increasing the amount of air in the high speed driving state and reducing the amount of intake during low speed driving. .

[실시예]EXAMPLE
이하 상기와 같은 본 고안의 바람직한 실시예를 첨부된 도면에 의하여 보다 상세히 설명한다.Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.
첨부된 도2는 본 고안의 차속에 따른 가변흡기 시스템을 나타낸 블록도이고, 도3은 본 고안의 차속에 따른 가변흡기 시스템을 나타낸 개략적인 단면도이다.2 is a block diagram showing a variable intake system according to the vehicle speed of the present invention, Figure 3 is a schematic cross-sectional view showing a variable intake system according to the vehicle speed of the present invention.
이에 도시된 바와 같이 본 고안의 차속에 따른 가변흡기 시스템은 마이크로 프로센서 등으로 구성될 수 있는 ECU(10)의 입력측에 차량의 속도를 감지하며 차속 감지신호를 발생하는 차속센서(2)가 접속되어 있고 출력측에는 ECU(10)의 제어신호를 받아 공기를 분사하도록 실린더(40)의 흡기 매니폴드(31)에 설치한 공기송출기(30)가 접속되어 구성된다.As shown therein, the variable intake system according to the vehicle speed of the present invention detects the speed of the vehicle at the input side of the ECU 10, which may be configured as a micro-pro sensor, and the vehicle speed sensor 2 generating a vehicle speed detection signal is connected. On the output side, an air blower 30 provided in the intake manifold 31 of the cylinder 40 is connected to the control unit so as to blow the air in response to the control signal of the ECU 10.
상기와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.
먼저 자동차에 시동을 걸면 전원이 인가되어 차량의 속도가 제어부(ECU)(10)에 입력되면 차속의 값에 따라 즉, 고속시 공기를 분출하고 저속시 공기분출량을 하지 않도록 제어신호를 발생하여 일정량의 공기만 분출한다.First, when the vehicle is started, the power is applied and the speed of the vehicle is input to the control unit (ECU) 10. According to the value of the vehicle speed, that is, the control signal is generated so that the air is ejected at high speed and the air is not ejected at low speed. Only blow out a certain amount of air.
이와 같이 고속, 가속, 등판등과 같은 운전시 차량이 고RPM이 되면 ECU(10)의 제어신호에 따라 흡기량의 양을 제어하게 된다.As such, when the vehicle becomes a high RPM during driving such as high speed, acceleration, climbing, etc., the amount of intake air is controlled according to the control signal of the ECU 10.
따라서 기존의 공기 흡입방식보다 혼합기로 유입되는 공기의 밀도를 높이고 차속에 따른 균일한 혼합기를 얻을 수 있다.Therefore, it is possible to increase the density of air flowing into the mixer and to obtain a uniform mixer according to the vehicle speed than the conventional air intake method.
상기와 같은 본 고안은 차량의 속도에 따라 흡입되는 공기의 량을 조절하므로써 엔진 성능을 향상함은 물론 배기가스 및 연비를 감소시켜 제품의 신뢰감을 높일 수 있는 이점이 있다.The present invention as described above has the advantage of improving the reliability of the product by reducing the exhaust gas and fuel economy as well as improving the engine performance by adjusting the amount of air sucked in accordance with the speed of the vehicle.
이상에서는 본 고안을 특정의 바람직한 실시예를 예를들어 도시하고 설명하였으나, 본 고안은 상기한 실시예에 한정되지 아니하며 본 고안의 정신을 벗어나지 않는 범위내에서 당해 고안이 속하는 기술분야에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 가능할 것이다.In the above, the present invention has been illustrated and described by way of specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the art to which the present invention belongs without departing from the spirit of the present invention.
