본 고안은 가솔린 엔진의 점화플러그 및 점화장치에 관한 것으로, 점화플러그의 구조를 변경하여 점화 횟수를 2회 점화까지 가능하도록하여 착화성, 엔진의 안전성 향상 및 완전연소를 할 수 있도록 하는 점화플러그의 구조 및 점화장치에 관한 것이다.The present invention relates to a spark plug and an ignition device for a gasoline engine, and to change the structure of the spark plug so that the number of ignitions can be ignited up to two times. It relates to a structure and an ignition device.
종래 장치는 제1도에 나타낸 바와같이, 콘트롤유니트(10), 이그나이터(11), 점화플러그(30)로 이루어져 있다.The conventional apparatus is composed of a control unit 10, an igniter 11, and a spark plug 30, as shown in FIG.
이러한 종래 장치는 흡입공기량, 수온, 노킹신호, 크랭크 각도등의 신호로서 콘트롤 유니트(10)에서 점화시기를 판단하여 이그나이터(11)로 점화시기제어신호를 인가하면 점화플러그(30)를 작동하여 A부분에서 방전전압을 발생하여 연료와 공기가 혼합된 혼합가스를 폭발하게 되어있다.The conventional apparatus determines the ignition timing by the control unit 10 as a signal of intake air amount, water temperature, knocking signal, crank angle, and the like, and when the ignition timing control signal is applied to the igniter 11, the ignition plug 30 is operated.

이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

The emitter terminal of the transistor TR1 is grounded, and the collector terminal of the transistor TR1 is connected to the other side of the primary coil CL1 connected to one of the anodes of the battery, through the diode D, and the other to ground. The capacitor C is connected in parallel to one of the primary coils of the secondary coil CL2, and the output terminal of the driving circuit 22 is connected to the base terminal of the transistor TR2, and the emitter of the transistor TR2 is The terminator terminal is grounded, the collector terminal of the transistor TR2 is connected to the other side of the primary coil of the secondary coil CL2, one side of the secondary coil of the secondary coil CL2 is grounded, and the other is Connected to the spark plug 30, connected to one of the secondary coils of the secondary coil CL2, having a resistor R in the spark plug 30, and passing through the resistor R to the first + pole 31; A negative electrode connected to the second positive electrode 32 without passing through the resistor R and grounded between the first positive electrode 31 and the second positive electrode 32. 33) is characterized by its technical construction.
이러한 본 고안 장치의 동작 및 작용효과를 제2도를 참조하여 설명하면 다음과 같다.If described with reference to Figure 2 the operation and effect of the device of the present invention.
먼저, 밧데리로 접속된 1차코일(CL1)은 밧데리의 전압을 점화코일에서 사용할수 있도록 승압을 하여 충전회로(21)에 인가하여 전압을 충전하게 된다.First, the primary coil CL1 connected to the battery is boosted to apply the voltage of the battery to the ignition coil and applied to the charging circuit 21 to charge the voltage.
한편, 콘트롤유니트(10)에서 인가되는 점화신호는 구동회로(22) 및 충전회로(21)호 인가되는데, 구동회로(22)의 출력측에 연결된 트랜지스터(TR2)는 상기 콘트롤유니트(10)에서 인가된 점화신호에 따라 온오프된다.Meanwhile, an ignition signal applied from the control unit 10 is applied to the driving circuit 22 and the charging circuit 21, and the transistor TR2 connected to the output side of the driving circuit 22 is applied from the control unit 10. On and off according to the ignition signal.
따라서, 충전회로(21)에 충전되었던 충전전압은 2차코일(CL2)을 통해서 점화코일 로 인가되어, 점화부 A,B에서 방전전압이 발생하여 혼합기체의 폭발을 일으킬 수 있다.Therefore, the charging voltage charged in the charging circuit 21 is applied to the ignition coil through the secondary coil CL2, and a discharge voltage may be generated in the ignition units A and B to cause explosion of the mixed gas.
한편, 점화플러그의 점화부A,B 에서 일어나는 방전에 대해서 설명하면, 엔진의 고회전시에는 전압이 충전되는 시간이 적기 때문에 효과적인 폭발을 위해서 제1 +극(31)에서 방전전압을 발생하고, 시동시나 엔진의 저회전시에는 전압이 충전되는 시간이 큰 경우에는 제2+극(32)에서 방전전압을 발생하게 된다.On the other hand, when the discharge occurs in the ignition parts A and B of the spark plug, since the time for charging the voltage is small during high rotation of the engine, the discharge voltage is generated at the first + pole 31 for effective explosion, and the start is performed. At the time of low rotation of the engine or the engine, when the voltage is charged, the discharge voltage is generated at the second + pole 32.
또한, 제2 +극(32)은 연소실 안쪽으로 삽입되어 착화성능의 증가와 완전연소로서 연비를 감소 할수 있다.In addition, the second + pole 32 may be inserted into the combustion chamber to increase the ignition performance and reduce fuel consumption as a complete combustion.
이상에서 살펴 본 바와 같이, 본 고안 장치는 엔진의 점화장치와 점화플러그의 점극부를 개조하여 안정적인 연소 및 엔진의 안전성향상을 할 수 있는 유용한 것이다.As described above, the device of the present invention is useful to improve the safety of the engine and stable combustion by modifying the ignition device of the engine and the ignition plug.
