Description

디젤기관용 예열플러그Preheating plug for diesel engine

본 고안은 디젤기관용 예열플러그에 관한 것으로서, 더욱 상세하게는 디젤기관 실린더의 연소실에 설치되어 한냉시 시동을 용이하게 하기 위하여 흡입공기를 따뜻하게 하는 예열플러그의 금속관에 방열핀을 형성하여 예열시간을 단축하여 시동성을 향상시키도록 한 디젤기관용 예열플러그에 관한 것이다.The present invention relates to a preheating plug for a diesel engine, and more particularly, a heat radiating fin is formed on a metal tube of a preheating plug that warms intake air to be installed in a combustion chamber of a diesel engine cylinder to facilitate starting in cold weather. The present invention relates to a preheating plug for a diesel engine to improve startability.

일반적으로 디젤기관에는 한냉시에 엔진의 시동을 용이하게 하기 위하여 흡입공기를 따뜻하게 하는 예열플러그가 설치된다.In general, a diesel engine is provided with a preheating plug for warming the intake air in order to facilitate the start of the engine in the cold.

첨부된 도면 도 1 및 도 2는 상기 예열플러그의 형상을 나타낸 것으로서, 예열플러그(10)의 하우징(12)의 일측에는 실린더(14)의 연소실(16)에 장치되도록 나사부(18)가 형성되고, 이 나사부(18)에 연결되는 홀딩핀(20)이 형성되며, 이 홀딩핀(20)에 그 일단이 고정되고 타단은 상기 하우징(12)에 연결된 금속관(22)의 일끝 내부측에 고정되는 열선코일(24)로 이루어진다.1 and 2 show the shape of the preheating plug, one side of the housing 12 of the preheating plug 10 is formed with a screw 18 to be installed in the combustion chamber 16 of the cylinder 14 The holding pin 20 is formed to be connected to the threaded portion 18, one end of which is fixed to the holding pin 20, and the other end of which is fixed to an inner side of one end of the metal tube 22 connected to the housing 12. It consists of a hot coil (24).

이러한, 상기 예열플러그(10)의 열선코일(24)은 가는 열선이 다수회 감겨져 전기저항이 크고, 상기 열선코일(24)이 상기 금속관(22) 내부에 내장되어 있기 때문에 열선코일(24)이 통전하면 금속관(22) 전체가 예열하도록 되어 있으며, 밧데리(도시되지 않음)와는 각 실린더(14)의 예열플러그(10) 모두 병렬로 접속되어 있다.Since the hot wire coil 24 of the preheating plug 10 has a large number of thin wires wound around it, the electrical resistance is high, and the hot wire coil 24 is embedded in the metal tube 22. When energized, the entire metal pipe 22 is preheated, and the preheating plug 10 of each cylinder 14 is connected to the battery (not shown) in parallel.

그러나, 디젤기관은 동절기의 시동전에 예열플러그(10)를 통해서 소정시간 예열시간을 필요로 하는데, 열선코일(24)이 외부로 노출되지 않고 상기 금속관(22) 내부에 내장되는 구조이기 때문에 연소실(16)의 온도의 상승이 지체되어 예열시간이 오래걸리므로 시동성에 문제가 있었다.However, the diesel engine requires a preheating time for a predetermined time through the preheating plug 10 before the start of the winter season, and since the hot wire coil 24 is not exposed to the outside and is built in the metal tube 22, the combustion chamber ( There was a problem in starting up because the rise of the temperature of 16) was delayed and the preheating time was long.

본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로서, 디젤기관의 실린더 연소실에 설치되어 동절기의 시동을 용이하게 하기 위하여 흡입공기를 따뜻하게 하는 예열플러그의 금속관에 주름을 형성하여 방열면적을 증대시킴으로써, 예열시간을 단축하여 시동성을 향상시키도록 한 디젤기관용 예열플러그를 제공함에 목적이 있다.The present invention is devised to solve the above problems, it is installed in the cylinder combustion chamber of the diesel engine to increase the heat dissipation area by forming a corrugation in the metal tube of the preheating plug to warm the intake air to facilitate the start of the winter season It is an object of the present invention to provide a preheating plug for a diesel engine that shortens the preheating time and improves startability.

상기와 같은 목적을 달성하기 위한 본 고안에 따른 디젤기관의 예열플러그는 금속관의 외부표면에 일정간격으로 배열되도록 돌출된 방열핀을 형성한 것을 특징으로 한다.The preheating plug of the diesel engine according to the present invention for achieving the above object is characterized in that the heat dissipating fins protruding to be arranged at a predetermined interval on the outer surface of the metal tube.

첨부된 도면 도 3은 본 고안에 따른 디젤기관용 예열플러그를 도시한 단면도이다.3 is a cross-sectional view showing a preheating plug for a diesel engine according to the present invention.

도시된 바와 같이 본 고안은 하우징(12)의 일측에는 각 실린더(14)의 연소실(16)에 장치되는 나사부(18)가 형성되고, 이 나사부(18)에 연되는 홀딩핀(20)을 형성하며, 이 홀딩핀(20)에 일단이 고정되고 타단은 상기 하우징(12)에 연결된 금속관(22)의 일끝 내부측에 고정되는 열선코일(24)로 이루어진 예열플러그(10)에 있어서, 상기 예열플러그(10)의 금속관(22) 외부 표면에는 일정간격으로 배열되어 돌출된 방열핀(30)이 형성된다.As shown in the present invention, one side of the housing 12 has a threaded portion 18 provided in the combustion chamber 16 of each cylinder 14, and a holding pin 20 connected to the threaded portion 18 is formed. In the preheating plug (10) consisting of a hot wire coil (24), one end of which is fixed to the holding pin (20) and the other end of which is fixed to an inner side of one end of the metal tube (22) connected to the housing (12). The heat dissipation fins 30 are formed on the outer surface of the metal tube 22 of the plug 10 and are protruded at regular intervals.

상기 방열핀(30)은 통상적으로 예컨대, 오토바이의 엔진 외부표면에 돌출된 핀등과 같이 리브(Rib)형태로 돌출시킨 것이다.The heat dissipation fins 30 are typically protruded in the form of ribs, such as fins protruding from the engine outer surface of the motorcycle.

이러한 방열핀(30)은 방열면적을 보다 크게 형성함으로써 연소실(16)내의 공기와 마찰되는 면적이 크고, 이에 따라 예열이 빠르게 이루어진다.The heat dissipation fin 30 has a larger heat dissipation area, so that the area that is rubbed with the air in the combustion chamber 16 is large.

이와 같이 시동의 스타터 스위치(도시되지 않음)를 예열의 위치로 조작하면 밧데리(도시되지 않음)에서의 전류는 스타터 스위치를 경유하여 각 실린더(14)의 연소실(16)에 설치된 예열플러그(10)로 각각 흘러 상기 예열플러그(10)를 예열한다.In this way, when the starter switch (not shown) of the start is operated to the position of preheating, the current from the battery (not shown) is preheated in the combustion chamber 16 of each cylinder 14 via the starter switch. Each preheats the preheating plug 10.

이때, 연소실(16)내의 공기와 마찰되는 금속관(22)의 방열면이 크게 형성되어 예열시간이 줄어든다.At this time, the heat dissipation surface of the metal tube 22 which is rubbed with the air in the combustion chamber 16 is formed large, thereby reducing the preheating time.

따라서, 예열플러그(10)의 금속관(22)의 표면적이 상기 방열판(30)에 의해서 증대됨으로 실린더(14)의 연소실(16) 흡입공기와 접하는 접촉면적이 증대하여 연소실(16) 온도를 빠르게 상승시켜 시동성을 향상시키는 것이다.Accordingly, the surface area of the metal tube 22 of the preheating plug 10 is increased by the heat sink 30, so that the contact area of the cylinder 14 with the intake air of the combustion chamber 16 increases, thereby rapidly increasing the temperature of the combustion chamber 16. It is to improve the startability.

한편, 운전자가 스타터 스위치를 시동의 위치로 조작하면 예열플러그(10)에서의 통전은 정지한다.On the other hand, when the driver operates the starter switch to the start position, the energization of the preheating plug 10 is stopped.

이상에서 살펴본 바와 같이 본 고안은 동절기 디젤기관 엔진의 시동을 용이하게 하기 위하여 연소실의 흡입공기를 따뜻하게 하는 예열플러그의 금속관 외부표면에 방열핀을 형성하여 신속하게 연소실의 온도를 상승시킴으로써, 엔진의 작동온도로 예열하여 시동성을 향상시키는 효과가 있다.As described above, the present invention forms a heat dissipation fin on the outer surface of the metal tube of the preheating plug that warms the intake air of the combustion chamber in order to facilitate the start of the winter diesel engine, thereby rapidly increasing the temperature of the combustion chamber, thereby operating the engine. Preheating is effective in improving the startability.
