Abstract

본 발명은 시이트형 예열플러그의 열효율증대장치에 관한 것으로, 보호금속판(11)내에 충전된 내열성절연분말(12)을 매개로 하이트코일(13)이 설치됨과 더불어, 실린더헤드에 결합되는 나사부(14)가 구비된 플러그하우징(15)을 매개로 홀딩핀(16)과 보호금속관(11)이 일체로 형성된 시이트형 예열플러그에 있어서, 상기 보호금속판(11)과 일체로 결합되는 쪽의 플러그하우징(15)에 실린더헤드와 결합되는 나사부(14)의 직경보다 작은직경의 나사부(1)가 형성되고, 이 나사부(1)에 실린더헤드의 소정위치로부터 끼워져 예연소실내부로 돌출되는 소정길이의 열전달용 특수합금링⑵이 중심에는 암나사(2´)가 형성되어 착탈가능하게 결합된 구조로되어, 상기 히이트코일⒀에 접하는 예열부의 체적을 확장시켜 예열실의 온도가 상대적으로 상승된 상태를 유지하게 됨과 동시에, 분사노즐로 부터 분사된 혼합연료의 분자운동을 확산시킴으로써 상대적으로 완전연소에 가까운 연소상태가 이루어지도록 된 것이다.The present invention relates to an apparatus for increasing the thermal efficiency of a sheet type preheating plug, wherein a height coil (13) is installed through a heat resistant insulating powder (12) filled in a protective metal plate (11), and a screw portion (14) coupled to a cylinder head. In the sheet type preheating plug in which the holding pin 16 and the protection metal pipe 11 are integrally formed through the plug housing 15 provided with the plug housing, the plug housing of the side which is integrally coupled with the protection metal plate 11 15) a threaded portion 1 having a diameter smaller than the diameter of the threaded portion 14 engaged with the cylinder head is formed, and is fitted to the threaded portion 1 from a predetermined position of the cylinder head to protrude into the pre-combustion chamber. Special alloy ring fins have a female thread (2 ') at the center and are detachably coupled to each other to expand the volume of the preheating unit in contact with the heat coil so that the temperature of the preheating chamber is kept relatively high. being At the same time, by spreading the molecular motion of the mixed fuel injected from the injection nozzle, a relatively close combustion state is achieved.
