Description
본 발명은 점화 플러그에 관한 것으로서, 특히 점화 플러그의 중심전극에 대해 일정거리 떨어진 상태로 맞대어지도록 형성되는 접지전극의 외주면상에 일정각도 경사진 다수의 돌기를 형성시켜 압축행정시 연소실에서 압축되는 혼합기가 상기 돌기들에 의해 작은 군집을 이루면서 와류되도록 하므로서, 엔진의 연소효율이 향상되고, 엔진의 출력 향상 및 카본 퇴적물 감소로 인한 제품의 수명 연장의 효과를 기대할 수 있도록 한 점화 플러그에 관한 것이다.The present invention relates to a spark plug, and in particular, to form a plurality of protrusions inclined at an angle on the outer peripheral surface of the ground electrode which is formed to be opposed to a predetermined distance to the center electrode of the spark plug is compressed in the combustion chamber during the compression stroke The present invention relates to an ignition plug, which allows vortices to be swirled in small clusters by the protrusions, thereby improving the combustion efficiency of the engine and improving the life of the product due to the improvement of the engine output and the reduction of carbon deposits.
일반적으로 점화플러그가 장착된 엔진에서는 연소실 내로 흡입된 혼합기를 압축시키고, 혼합기가 고압으로 압축된 상태에서 점화플러그에 고전압을 인가하여 불꽃이 발생되도록 하므로서, 연소실 내의 혼합기가 연소되도록 하여 동력을 발생하고 있다.In general, an engine equipped with a spark plug compresses a mixer sucked into the combustion chamber and generates a spark by applying a high voltage to the spark plug while the mixer is compressed at a high pressure, thereby causing the mixer in the combustion chamber to burn to generate power. have.
이러한 엔진에서는 연소실 내에 존재하게 되는 혼합기의 연소압이 연소효율에 큰 영향을 미치고 있는 실정이며, 연소압은 점화시 연소실 내에 압축 상태로 존재하게 되는 혼합기의 난류강도에 큰 영향을 받는 것으로 알려져있다.In such an engine, the combustion pressure of the mixer which exists in the combustion chamber has a great influence on the combustion efficiency, and the combustion pressure is known to be greatly influenced by the turbulence strength of the mixer which exists in the compressed state in the combustion chamber during ignition.
도 1 은 종래의 점화 플러그를 도시한 것으로서,1 shows a conventional spark plug,
몸체(1)의 저면 중앙에 중심전극(2)이 형성되어 있고, 이 중심전극(2)에 대해 일정거리 떨어지도록 접지전극(3)이 형성된 구성이다.The center electrode 2 is formed in the center of the bottom face of the body 1, and the ground electrode 3 is formed so that a predetermined distance may be separated from this center electrode 2. As shown in FIG.
상기와같이 구성된 점화플러그는 점화시 외부로 부터 인가되는 고전압이 중심전극(2)에 가해지고, 중심전극(2)에 가해진 전압이 접지전극(3)으로 방전되면서 불꽃이 발생되어 연소실에 압축된 상태로 존재하는 혼합기가 연소되는 것이다.In the ignition plug configured as described above, the high voltage applied from the outside during ignition is applied to the center electrode 2, and the voltage applied to the center electrode 2 is discharged to the ground electrode 3 so that sparks are generated and compressed into the combustion chamber. The mixer present in the state is burned.
종래의 점화 플러그는 그 끝부분이 연소실 내부로 돌출되도록 설치되는 것이므로 연소실 내의 혼합기 유동에 영향을 미치나 그 영향 정도가 단순히 혼합기의 유동에 교란을 주는 정도에 그치고 있으므로 혼합기의 연소압을 향상시키는 데에는 큰 역할을 하지 못하고 있으며, 이로인해 혼합기의 연소시 연소율이 감소하게되어 불완전 연소에 의해 발생하는 카본이 중심전극에 퇴적되면서 점화플러그의 수명이 단축되는 문제점이 있었다.Conventional spark plugs are installed so that their ends protrude into the combustion chamber, thus affecting the flow of the mixer in the combustion chamber, but the influence of the spark plug is merely disturbing the flow of the mixer. It does not play a role, and as a result, the combustion rate of the mixer decreases, resulting in a problem that the life of the spark plug is shortened as carbon generated by incomplete combustion is deposited on the center electrode.
따라서, 상기 문제점을 해결하기 위한 본 발명은 점화 플러그의 중심전극에 대해 일정거리 떨어진 상태로 맞대어지도록 형성되는 접지전극의 외주면상에 일정각도 경사진 다수의 돌기를 형성시켜 압축행정시 연소실에서 압축되는 혼합기가 상기 돌기들에 의해 작은 군집을 이루면서 와류되도록 하므로서, 엔진의 연소효율이 향상되고, 엔진의 출력 향상 및 카본 퇴적물 감소로 인한 제품의 수명 연장의 효과를 기대할 수 있도록 한 점화 플러그를 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is to form a plurality of protrusions inclined at an angle on the outer peripheral surface of the ground electrode which is formed to be opposed to a predetermined distance with respect to the center electrode of the spark plug is compressed in the combustion chamber during the compression stroke It is an object of the present invention to provide a spark plug which allows the mixer to vortex in small clusters by the projections, thereby improving the combustion efficiency of the engine and prolonging the life of the product by improving the engine output and reducing carbon deposits. It is done.
상기 목적달성을 위한 본 발명은,The present invention for achieving the above object,
몸체의 저면에 중심전극이 돌출 형성되어 있고, 이 중심전극의 하측으로는 접지전극이 일정간격을 두고 맞대어지도록 형성되어 있는 점화플러그에 있어서,In the spark plug formed with a center electrode protrudingly formed on the bottom of the body, the ground electrode is formed to face each other at a predetermined interval below the center electrode,
상기 접지전극의 외주면에 다수의 와류 발생용 돌기를 돌출 형성시킨 것을 특징으로 한다.A plurality of vortex generating protrusions protrude from the outer circumferential surface of the ground electrode.
그리고, 상기 돌기는 일정각도 경사지게 비스듬이 형성시켜 혼합기와의 접촉면적이 넓어지도록 한 것을 특징으로 한다.In addition, the protrusion is formed to be inclined at a predetermined angle so as to increase the contact area with the mixer.

1 : 몸체 2 : 중심전극1 body 2 center electrode
3 : 접지전극 10 : 돌기3: earth electrode 10: protrusion
이하, 첨부된 도면 도 2 와 도 3 을 참고하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings Figures 2 and 3 will be described a preferred embodiment of the present invention.
도면부호 1 은 점화 플러그의 몸체를 나타내는데, 이 몸체(1)의 저면 중앙에는 외부로 부터 높은 전압이 인가되는 중심전극(2)이 형성되어 있고, 이 중심전극(2)의 하측으로는 몸체(1)로 부터 연장되도록 형성된 접지전극(3)이 중심전극(2)과 일정거리를 두고 맞대어지도록 형성되어 있다.Reference numeral 1 denotes a body of a spark plug, and a center electrode 2 to which a high voltage is applied from the outside is formed in the center of the bottom of the body 1, and below the center electrode 2, a body ( The ground electrode 3 formed to extend from 1) is formed to face the center electrode 2 at a predetermined distance.
상기 접지전극(3)에는 도 3 에 도시된 바와같이 다수의 돌기(10)를 형성하였는데, 이 돌기(10)들은 일정각도 비스듬이 경사지도록 돌출시켜 혼합기와의 접촉면적이 넓어지도록 하였다.As shown in FIG. 3, a plurality of protrusions 10 are formed on the ground electrode 3, and the protrusions 10 protrude so as to be inclined at a predetermined angle to widen the contact area with the mixer.
접지전극(3)에 다수의 돌기(10)를 형성시키면, 연소실로 유입된 혼합기가 압축될때 혼합기가 돌기(10)들 사이로 유동되면서 도 3 에 도시된 바와같이 각각의 돌기(10) 사이 및 돌기(10) 부근에 소규모의 와류가 발생하게 되어 점화 플러그 부근의 혼합기 난류강도가 향상된다.When the plurality of protrusions 10 are formed on the ground electrode 3, when the mixer introduced into the combustion chamber is compressed, the mixer flows between the protrusions 10, and as shown in FIG. 3, between each protrusion 10 and the protrusions. Small eddy currents are generated in the vicinity of (10), thereby improving the turbulence strength of the mixer near the spark plug.
혼합기의 난류강도가 증가하게 되면, 점화 플러그의 점화시 연소압이 증가하게 되어 혼합기의 완전연소를 꾀할 수 있음은 물론 엔진의 출력을 월등히 향상시킬 수 있다.When the turbulence strength of the mixer is increased, the combustion pressure is increased when the spark plug is ignited, and thus the combustion of the mixer can be completely burned, and the output of the engine can be greatly improved.
또한, 혼합기의 완전연소에 의해 연소 동작시 카본의 발생양이 감소하게 되어 중심전극(2)에 퇴적되는 카본의 양이 현저히 감소하여 점화 플러그의 수명이 연장되는 부가적인 효과를 기대할 수 있다.In addition, due to the complete combustion of the mixer, the amount of carbon generated during the combustion operation is reduced, and the amount of carbon deposited on the center electrode 2 is remarkably reduced, so that an additional effect of extending the life of the spark plug can be expected.
그리고, 돌기(10)들을 일정각도 경사지게 형성하면 돌기(10)와 혼합기의 접촉면적이 넓어지므로 각각의 돌기(10) 사이에서 발생하는 와류의 강도가 강해져 그만큼 혼합기의 연소율이 증가하게 되는 것이다.In addition, when the protrusions 10 are formed to be inclined at a predetermined angle, the contact area between the protrusions 10 and the mixer becomes wider, and thus the strength of the vortices generated between each of the protrusions 10 becomes stronger, thereby increasing the combustion rate of the mixer.
이상에서 설명한 바와같이 본 발명은 점화 플러그의 중심전극에 대해 일정거리 떨어진 상태로 맞대어지도록 형성되는 접지전극의 외주면상에 일정각도 경사진 다수의 돌기를 형성시켜 압축행정시 연소실에서 압축되는 혼합기가 상기 돌기들에 의해 작은 군집을 이루면서 와류되도록 하므로서, 엔진의 연소효율이 향상되고, 엔진의 출력 향상 및 카본 퇴적물 감소로 인한 제품의 수명 연장의 효과를 기대할 수 있도록 한 점화 플러그이다.As described above, the present invention forms a plurality of protrusions which are inclined at an angle on the outer circumferential surface of the ground electrode which is formed to face each other at a predetermined distance from the center electrode of the spark plug. It is a spark plug that allows the vortex to form a small group by protrusions, thereby improving the combustion efficiency of the engine and improving the life of the product due to the improvement of the engine output and the reduction of carbon deposits.
