본 발명은 내연기관의 점화코일에 관한 것으로, 특히 배전효율을 향상시키고 제조단가를 절감시킬 수 있도록 된 내연기관용 동시점화식 점화코일구조에 관한 것이다.The present invention relates to an ignition coil of an internal combustion engine, and more particularly, to a co-ignition type ignition coil structure for an internal combustion engine that can improve distribution efficiency and reduce manufacturing costs.
점화장치에 있어서 점화코일은, 실린더의 점화순서에 따라 점화플러그의 불꽃 간극에 강한 불꽃을 튀길 수 있도록 배터리나 발전기의 저전압을 고전압의 전류로 바꾸어 주는 유도코일인 바, 이러한 점화코일은 예컨대 4기통 엔진의 경우 각 실린더에 1개씩 4개의 점화코일이 독립적으로 배치되어 배전기에서 지정하는 엔진의 점화순서에 따라 해당되는 연소실내의 혼합가스를 점화시키도록 되어 있다.In the ignition device, the ignition coil is an induction coil that converts the low voltage of the battery or the generator into a high voltage current so that a strong spark can be popped in the spark gap of the spark plug according to the ignition order of the cylinder. In the case of an engine, four ignition coils, one for each cylinder, are independently arranged to ignite the mixed gas in the combustion chamber according to the ignition order of the engine specified by the distributor.
즉 제4도에 도시된 것과 같이 일측에 콘넥터(40)가 설치된 몸체(41)의 하부에 고압타워부(42)가 형성된 점화코일(43)이, 상부고무캡(44)과 하부고무캡(45)으로 분할형성된 점화플러그접속부재(46)를 매개로 실린더(도시되지 않음)의 연소실에 장착된 점화플러그(47)와 접속됨과 더불어 상기 콘넥터(40)에 전원단자를 연결시키도록 된 구조로 되어, 점화코일(43)에서 발생된 고압전류가 해당되는 실린더에 설치된 점화플러그를 통해 연소실내에서 압축된 혼합가스로 점화하는 작용을 하도록 되어 있다.That is, as shown in FIG. 4, the ignition coil 43 in which the high-pressure tower portion 42 is formed at the lower portion of the body 41 on which the connector 40 is installed on one side thereof is provided with an upper rubber cap 44 and a lower rubber cap ( 45 is connected to the spark plug 47 mounted in the combustion chamber of the cylinder (not shown) through the spark plug connecting member 46 divided into parts, and to connect the power terminal to the connector 40. Thus, the high-pressure current generated from the ignition coil 43 serves to ignite the mixed gas compressed in the combustion chamber through an ignition plug installed in the corresponding cylinder.
그러나 이러한 구조로 이루어진 종래의 점화코일은, 각 실린더에 1개씩 점화코일을 독립적으로 설치하여 해당되는 실린더에 설치된 점화플러그로 배전작용을 함에 따라 배전기내에서 배전작용에 의한 장해전파가 크게 발생될 뿐만 아니라 실린더의 수만큼 점화코일이 필요하고, 또 상기 점화플러그접속부재가 분할형성되어 있음으로 인하여 제조단가가 상승되고 조립공정이 번거로와 생산성이 저하된다는 문제점이 있었다.However, in the conventional ignition coil having such a structure, as a single ignition coil is installed in each cylinder and the distribution is performed by the ignition plug installed in the corresponding cylinder, interference propagation due to the distribution effect is largely generated in the distribution. Instead, the number of ignition coils is required as many as the number of cylinders, and since the spark plug connection members are dividedly formed, there is a problem in that the manufacturing cost is increased and the assembly process is cumbersome and the productivity is lowered.
이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 1개의 점화코일에 2개의 점화플러그를 접속시킬 수 있도록하여 동시점화식으로 배전작용을 하도록 함으로써 전파장해가 발생하는 것을 최소화하여 배전효율을 향상시키는 한편, 점화플러그접속부재를 일체화시킴으로써 제조단가를 절감시키고 생산성을 향상시킬 수 있도록 된 내연기관용 동시점화식 점화코일구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, it is possible to connect two spark plugs to one ignition coil to perform the distribution operation by the ignition co-simulation to minimize the occurrence of radio interference by reducing the distribution efficiency On the other hand, an object of the present invention is to provide a co-ignition type ignition coil structure for an internal combustion engine that can reduce the manufacturing cost and improve productivity by integrating the spark plug connecting member.
상기와 같은 목적을 달성하기 위한 본 발명은, 몸체의 일측에원통형상으로 된 수용부와 이 수용부내에 돌출형성된 단자를 구비한 제2고압타워부가 설치되고, 제1고압타워부가 한쪽끝부분에 일체로 형성된 플랜지부와 내주면 소정위치에 돌출부와 걸림홈이 단계적으로 형성된 凸부를 갖춘 점화플러그접속부재를 매개로 해당되는 점화플러그에 접속되는 한편, 상기 제2고압타워부와 제1고압타워부가 동시배전을 행할 수 있도록 상호 전기적으로 연결된 구조로 되어 있다.In order to achieve the above object, the present invention provides a second high-pressure tower portion having a cylindrical portion and a protruding terminal formed in the receiving portion on one side of the body, the first high-pressure tower portion at one end portion; An integrally formed flange portion and an inner circumferential surface are connected to a corresponding spark plug via a spark plug connecting member having a convex portion in which protrusions and engaging grooves are formed step by step, while the second high pressure tower portion and the first high pressure tower portion are simultaneously. The structure is electrically connected to each other so that power distribution can be performed.
이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 점화코일의 연결상태를 부분절개도로 도시한 것이고 제2도는 제1도에서의 점화플러그접속부재의 절개단면도로서, 일측에 콘넥터(1)가 설치된 몸체(2)의 하부에 제1고압타워부(3)가 형성됨과 더불어, 상기 콘넥터(1)와 대향되는 몸체(2)의 측벽에 제2고압타워부(4)가 설치된 점화코일(5)이 갖추어지면서, 상기 제1고압타워부(3)는 실리콘재질로 이루어진 점화플러그 접속부재(6)를 매개로 점화플러그(7)에 접속되고, 상기 제2고압타워부(4)는 하이텐션코드(도시되지 않음)에 직접 접속되도록 된 구조로 되어 있다.1 is a partial cutaway view showing a connection state of the ignition coil according to the present invention, and FIG. 2 is a cutaway cross-sectional view of the spark plug connecting member in FIG. 1, the lower part of the body 2 having the connector 1 installed on one side thereof. While the first high pressure tower portion 3 is formed in the ignition coil 5 having the second high pressure tower portion 4 provided on the side wall of the body 2 facing the connector 1, The first high pressure tower portion 3 is connected to the spark plug 7 via a spark plug connecting member 6 made of a silicon material, and the second high pressure tower portion 4 is connected to a high tension cord (not shown). It is structured to be connected directly.
여기서 상기 제1고압타워부(3)는 몸체(2)의 하부면 측부에 수직방향으로 돌출형성되면서, 소정위치에 외주면을 따라 걸림홈(8)과 돌출부(9)로 이루어진 凹부(10)가 형성됨과 더불어 끝부분으로는 단자(도시되지 않음)가 안착되어 있는 한편, 상기 제2고압타워부(4)는 원통형상으로 된 수용부(11)를 갖추고 이 수용부(11)내측으로 단자(12)가 돌출되도록 설치되어, 별도의 접속수단 없이 직접 하이텐션코드에 접속시킬 수 있도록 되어 있다.Wherein the first high-pressure tower portion (3) protruding in the vertical direction on the lower surface side of the body (2), the concave portion (10) consisting of a locking groove (8) and a projection (9) along the outer circumferential surface at a predetermined position And a terminal (not shown) is seated at an end thereof, while the second high-pressure tower portion 4 has a receiving portion 11 having a cylindrical shape, and the terminal inside the receiving portion 11. (12) is provided so as to protrude, and can be directly connected to the high tension cord without a separate connecting means.
그리고 상기 점화플러그접속부재(6)는 제1도 및 제2도에 도시된 것과 같이, 몸체(13)의 중앙부에 내경을 따라 소정의 끼움홈(14)이 단계적으로 형성되면서 이 끼움홈(14)을 매개로 알루미늄 재질로 이루어진 캔(15)이 탄력적으로 끼워져 고정되게 되는 바, 이 캔(15)의 내측으로는 스프링(16)이 끼워지면서 이 스프링(16)의 한쪽 끝부분이 상기 캔(15)의 상단부에 고정됨과 더불어 상기 스프링(16)의 안쪽으로는 저항(17)이 수납되어, 점화플러그(7)에 접속시키게 되면 저항(17)이 밀려지면서 상기 제2고압타워부(3)의 저항과 맞닿을 수 있도록 되어 있는 한편, 상기 몸체(13)의 한쪽 끝부분에는 플랜지부(18)가 형성되고 이 플랜지부(18)와 인접된 위치에 내경을 따라 소정의 돌출부(19)와 걸림홈(20)이 단계적으로 형성되어 이루어진 凸부(21)가 갖추어진 구조로 되어 있고, 저항(17)이 필요없는 경우 상기 캔(15)을 연장 형성시켜 스프링(16)이 제1고압타워부(3)에 직접 접촉되도록 구성시킬 수도 있다.And the spark plug connecting member 6, as shown in Figures 1 and 2, a predetermined fitting groove 14 is formed in the central portion of the body 13 along the inner diameter in stepwise fitting groove 14 The can 15 made of an aluminum material is elastically fitted to be fixed to the bar. A spring 16 is inserted into the can 15, and one end of the spring 16 is inserted into the can 15. 15 is fixed to the upper end of the spring 16, the resistor 17 is received in the inner side of the spring 16 is connected to the spark plug 7, the resistance 17 is pushed while the second high-pressure tower portion (3) On the other hand, a flange portion 18 is formed at one end of the body 13 and a predetermined protrusion 19 is formed along the inner diameter at a position adjacent to the flange portion 18. The locking groove 20 is formed in the structure is provided with a concave portion 21 is formed in stages, If you do not need anti-17 to extend the can 15 may be configured so that spring 16 is directly in contact with the first high-voltage tower portion 3.
또한 상기 점화코일(5)은, 제1고압타워부(3)와 제2고압타워부(4)에 해당되는 실린더위에 취부된 점화플러그(7) 및 다른 한쪽 실린더에 연결된 하이텐션코드를 각각 접속시킴으로써 동시배전을 행할 수 있도록 전기적으로 연결되어 있는 바, 즉 제3도에 도시된 것과 같이 코일의 한쪽 끝부분에 제1실린더와 제2실린더가 동시에 연결되고 다른쪽 끝부분에 제4실린더와 제3실린더가 동시에 연결되어, 변압부에 연결된 밧데리전원(B+)에 전압이 인가됨과 더불어 엔진제어컴퓨터(ECU)의 제어신호가 인가되면, 상기 변압부내에서 변환된 출력전압이 상기 제어신호에 의하여 제1실린더와 제4실린더 및 제2실린더와 제3실린더에서 동시에 방전되게 되고, 이와같이 동시방전이 이루어진다 해도, 예컨대 제1실린더가 압축행정일때에는 제2실린더는 배기행정이므로 압축행정쪽으로 대부분의 전압이 방전되게 되어 배기행정으로 전압이 누설되는 것이 방지되고, 제2실린더가 압축행정이면 제1실린더가 배기행정으로 되게 되므로 전기통에 걸쳐 계속 반복적으로 방전작용이 이루어지게 된다.In addition, the ignition coil 5 connects the ignition plug 7 mounted on the cylinder corresponding to the first high pressure tower part 3 and the second high pressure tower part 4 and the high tension cord connected to the other cylinder, respectively. The first cylinder and the second cylinder are simultaneously connected to one end of the coil and the fourth cylinder and the first end are connected to the other end as shown in FIG. When the three cylinders are connected at the same time, the voltage is applied to the battery power source B + connected to the transformer, and the control signal of the engine control computer ECU is applied, the output voltage converted in the transformer is converted by the control signal. The first cylinder, the fourth cylinder, the second cylinder, and the third cylinder are discharged at the same time. Even if simultaneous discharge is performed in this way, for example, when the first cylinder is a compression stroke, the second cylinder is an exhaust stroke. Since most of the voltage is discharged to the stroke to prevent leakage of the voltage to the exhaust stroke, and if the second cylinder is a compression stroke, the first cylinder becomes the exhaust stroke, and thus the discharge operation is repeatedly performed throughout the electric cylinder.
이하 본 발명에 따른 작동에 대하여 설명한다.Hereinafter, the operation according to the present invention will be described.
본 발명에 따른 점화코일(5)은 예컨대 4기통엔진의 경우 2개의 점화코일로서 엔진의 4사이클 행정을 모두 수행할 수 있도록 되어 있는 바, 즉 점화코일(5)에 설치된 제1고압타워부(3)에 해당기통과 연결된 점화플러그를 접속시키고, 제2고압타워부(4)에는 다른 기통에 연결된 하이텐션코드를 접속시키게 되면 제1 및 제4기통에서 방전이 동시에 발생하게 된다.The ignition coil 5 according to the present invention, for example, in the case of a four-cylinder engine, is capable of performing all four cycles of the engine as two ignition coils, that is, a first high-pressure tower part installed in the ignition coil 5 ( When the spark plug connected to the corresponding cylinder is connected to 3), and the high tension cord connected to the other cylinder is connected to the second high pressure tower unit 4, the discharge occurs simultaneously in the first and fourth cylinders.
그러나 제1기통이 어떤 크랭크각에서 압축운동공정에 있고 제4기통이 배기운동 공정에 있으면, 제1점화플러그에서만 방전되게 되고 제1기통은 폭발공정으로 들어가게 되고, 다음에 상기 점화로부터 크랭크각이 360°에 있으면, 또 다시 제1 및 제4점화플러그에서 방전이 동시에 발생하게 된다. 그러나 이때 제4기통이 압축운동공정에 있는 동안, 제1기통은 배기운동상태에 있게 되므로 제4기통의 점화만이 작용하게 된다.However, if the first cylinder is in the compression movement process at some crank angle and the fourth cylinder is in the exhaust movement process, it is discharged only in the first ignition plug and the first cylinder enters the explosion process, and then the crank angle from the ignition is If it is at 360 °, the discharge will occur simultaneously in the first and fourth ignition plugs again. However, at this time, while the fourth cylinder is in the compression movement process, the first cylinder is in the exhaust movement state, so only the ignition of the fourth cylinder acts.
한편 상기 점화플러그접속부재(6)가 일체형으로 형성됨과 더불어 그 내경을 따라 걸림홈(20)과 돌출부(19)로 이루어진 凸부(21)를 갖추고 있어, 상기 제1고압타워부(3)에 상기 접속부재(6)를 끼워주게 되면 이 접속부재(6)의 플랜지부(18)가 타워부(3)의 아랫면에 밀착되면서 접속부재(6)에 형성된 凹부(10)가 제1고압타워부(3)에 형성된 凸부(21)에 끼워지게 되어, 1번의 공정으로 연결작업을 완료할 수 있게 되므로 조립작업을 단순화시킴은 물론 제조단가도 절감되게 된다.On the other hand, the spark plug connecting member 6 is formed integrally, and has a concave portion 21 formed of a locking groove 20 and a protrusion 19 along its inner diameter, so that the first high-pressure tower portion 3 When the connecting member 6 is fitted, the flange portion 18 of the connecting member 6 comes into close contact with the lower surface of the tower portion 3 and the convex portion 10 formed on the connecting member 6 is the first high pressure tower. Since it is fitted to the concave part 21 formed in the part 3, the connection work can be completed in one step, thereby simplifying the assembly work and also reducing the manufacturing cost.
이상에서 설명한 것과 같이 본 발명 내연기관용 동시점화식 점화코일에 의하면, 2개의 점화코일로 4기통엔진을 정상적으로 작동시킬 수 있도록 되어 배전효율을 향상시키고, 점화코일 접속부재를 일체형으로 형성시킴으로써 제조단가를 절감시킬 수 있게 된다.As described above, according to the present invention, the ignition coil for internal combustion engines can operate a four-cylinder engine normally with two ignition coils, thereby improving distribution efficiency and reducing the manufacturing cost by forming the ignition coil connection member integrally. You can do it.
