Description
본 발명은 배전기가 없는 점화장치에 관한 것이며, 보다 상세히는 광센서를 사용하여 점화시기를 검출하는 배전기가 없는 점화장치에 관한 것이다.The present invention relates to an ignition device without a distributor, and more particularly, to an ignition device without a distributor for detecting an ignition timing using an optical sensor.
종래의 배전기가 없는 점화장치는 다음과 같이 작동한다.A conventional distributorless ignition device operates as follows.
실린더 헤드에 설치된 센서(1)는 점화시기를 검출하여 감지된 신호를 ECU(4)로 보내고, 상기 ECU(4)는 엔진의 회전수를 연산하여 점화 2차 고전압 전류를 발생시키는 점화 코일(5)의 전류 발생을 제어하고, 상기 점화 코일(50은 점화 2차 고전압 전류를 스파크 플러그(6)로 보내어 스파크 플러그(6)를 점화시킨다.The sensor 1 installed in the cylinder head detects the ignition timing and sends the detected signal to the ECU 4, the ECU 4 calculating the number of revolutions of the engine to generate the ignition secondary high voltage current 5 Control the generation of current, and the ignition coil 50 sends an ignition secondary high voltage current to the spark plug 6 to ignite the spark plug 6.
상기 센서(1)는 크랭크 앵글 센서(2; CRANK ANGLE SENOR)와 페이스 센서(3; PHASE SENSOR)가 짝을 이루어 점화시기를 검출한다.The sensor 1 detects an ignition timing by pairing a crank angle sensor 2 (CRANK ANGLE SENOR) and a face sensor 3 (PHASE SENSOR).
상기 크랭크 앵글 센서(2)는 발광 다이오드와 포토 다이오드를 이용하여 신호를 검출하고, 상기 신호를 디지털 신호로 바꾸어 ECU(4)에 입력한다.The crank angle sensor 2 detects a signal using a light emitting diode and a photodiode, converts the signal into a digital signal, and inputs the signal to the ECU 4.
상기 페이스 센서(3)는 캠 샤프트에 타겟 휠을 만들고, 상기 타겟 휠에 형성된 돌기에 의한 자장의 변화를 감지하며, 상기 감지된 신호를 ECU(4)로 전송한다.The face sensor 3 makes a target wheel on the camshaft, detects a change in the magnetic field due to the protrusion formed on the target wheel, and transmits the detected signal to the ECU 4.
상기와 같은 종래의 배전기가 없는 점화장치는 점화 코일(5)을 스파크 플러그(6) 가까이 설치할 수 있어 고압 케이블의 저항에 의한 실화를 방지하며, 고압 배전으로 인한 전파 방해가 일어나지 않는다. 특히 원심식 및 진공식 진각장치의 기계적 소음과 단속기 암 스프링의 피로에 의한 영향이 적어 고속 회전에서 늦어지기 쉬운 점화를 확실히 행하는 장점이 있다.The conventional ignition device without the distributor may install the ignition coil 5 near the spark plug 6 to prevent misfire due to the resistance of the high voltage cable, and does not cause radio interference due to the high voltage distribution. In particular, the mechanical noise of the centrifugal and vacuum advance devices is less affected by the fatigue of the chopper arm spring, and thus there is an advantage that the ignition that is likely to be delayed at high speed rotation is surely performed.
그러나, 상기와 같은 종래의 배전기가 없는 점화장치는 센서의 장착 조건(위치, 방향)이 매우 난이하고, 또한 차종에 따라 장착 방법이 달라 센서를 장착하기 매우 어려웠다.However, such a conventional ignition device without a distributor is very difficult to mount the sensor because the mounting conditions (position, direction) of the sensor is very difficult and the mounting method varies depending on the vehicle model.
따라서, 본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 발명의 목적은 차종의 상이에 상관없고, 장착 조건에 무관하도록 캠을 기준으로 하여 실린더 헤드 양쪽에 광센서를 장착한 배전기가 없는 점화장치를 제공하는데 있다.Accordingly, the present invention is to overcome the above-mentioned conventional problems, and the object of the present invention is that regardless of the type of the vehicle, there is no distributor having an optical sensor mounted on both sides of the cylinder head relative to the cam so as to be independent of the mounting conditions. To provide an ignition device.
상기 본 발명의 목적을 달성하기 위한 배전기가 없는 점화장치의 일예로서, 광센서의 발광부와 수광부가 캠 샤프트에 장착된 캠을 기준으로 하여 실린더 헤드 양쪽에 각각 장착되는 것을 특징으로 한다.As an example of an ignition device without a distributor for achieving the object of the present invention, the light emitting portion and the light receiving portion of the optical sensor is characterized in that mounted on both sides of the cylinder head on the basis of the cam mounted on the cam shaft.
이러한 구성에 의해, 용이하게 점화시기를 검출할 수 있고, 또한 장착하기 용이하여 비용이 절감된다.By such a configuration, the ignition timing can be easily detected, and it is easy to mount, thereby reducing the cost.

이하, 본 발명의 실시예를 도 2 및 도 3을 참조하여 상세히 설명하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.
도 1을 참조하면, 본 발명에 따른 배전기가 없는 점화장치에 있어서, 광센서(15)는 캠 샤프트(11)에 장착된 캠(12)을 기준으로 하여 실린더 헤드(18) 양쪽에 발광부(16)와 수광부(17)가 각각 장착된다.Referring to FIG. 1, in the ignition apparatus without the distributor according to the present invention, the optical sensor 15 has a light emitting portion (both on the cylinder head 18) on the basis of the cam 12 mounted on the cam shaft 11. 16 and the light receiving portion 17 are mounted, respectively.
상기와 같은 장착된 광센서는 다음과 같이 작동한다.The mounted optical sensor operates as follows.
캠(12)에 형성된 로브(13)가 A에 위치하게되면, 발광부(16)에서 방출되는 광을 수광부(17)가 감지하여 하이(HIGH) 신호를 ECU(도시하지 않음)로 송신한다. 그리고, 캠(12)에 형성된 로브(13)가 B에 위치하게되면, 발광부(16)에서 방출되는 광을 로브(13)에 차단하여 수광부(17)에서 상기 광을 감지하지 못하게 된다. 따라서, 수광부(17)는 로(LOW) 신호를 ECU로 송신한다.(도 2 참조)When the lobe 13 formed on the cam 12 is positioned at A, the light receiving unit 17 detects the light emitted from the light emitting unit 16 and transmits a HIGH signal to the ECU (not shown). When the lobe 13 formed on the cam 12 is positioned at B, the light emitted from the light emitting unit 16 is blocked to the lobe 13, thereby preventing the light receiving unit 17 from detecting the light. Therefore, the light receiving unit 17 transmits a LOW signal to the ECU. (See FIG. 2).
상술한 바와 같이 본 발명에 따른 배전기가 없는 점화장치는 광센서가 캠을 기준으로 하여 실린더 헤드 양쪽에 장착되므로서, 용이하게 점화시기를 검출할 수 있고, 또한 장착하기 용이하여 비용이 절감되는 효과가 있다.As described above, the ignition device without the distributor according to the present invention has an optical sensor mounted on both sides of the cylinder head on the basis of the cam, so that the ignition timing can be easily detected and the cost can be easily reduced by mounting. There is.
이상에서 설명한 것은 본 발명에 따른 배전기가 없는 점화장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구의 범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is only one embodiment for implementing the distributor-free ignition device according to the present invention, the present invention is not limited to the above-described embodiment, the gist of the present invention claimed in the following claims Various changes can be made by those skilled in the art without departing from the scope of the present invention.
