Problems solved by technology

The disadvantage is that when the gas is ignited, due to the low temperature of the cold electrode itself, it will absorb part of the energy, which may cause the ignited gas to extinguish suddenly, affecting the smooth ignition

Abstract

This invention relates to an ignition plug by using all-ceramic electrically heating unit as the central electrode. It is composed of: the shell of the ignition plug (SIP), a side electrode (SE), a central electrode (CE), an upper insulation tube (UIT), a lower insulation tube (LIT) and a conducting electrode (CDE). The SIP, connecting SE, is equipped on the engine. The CE is equipped in the upper part of the inner hole of SIP, between its upper end and the SE is clearance. The CE comprises an external resistance layer (ERL), insulation layer (IL) and inner conducting layer (ICL). An interlinkage hole is at the upper end of IL, the partial material of ERL and partial material of ICL are inter linked through said hole. A receptacle of the CDE is at the lower end of ICL, the CED is in the receptacle. The UIT is at the upper part of the inner hole of SIP, as the LIT at the lower part. This invention ensures the stable burning of gas.

Description

technical field [0001] The invention belongs to the technical field of electric spark ignition equipment characterized by the generation of ignition energy. Background technique [0002] In prior art engine ignition spark plugs, the central electrode is a cold electrode. The disadvantage is that when the gas is ignited, due to the low temperature of the cold electrode itself, it will absorb part of the energy, which may cause the ignited gas to extinguish suddenly and affect the smooth ignition. Contents of the invention [0003] The technical problem to be solved is to provide a spark plug with an all-ceramic heating body as the center electrode that can ensure smooth ignition. [0004] The technical solution to solve its technical problems is as follows: a spark plug with a ceramic electric heating body as the central electrode, including a spark plug shell, a side electrode, a central electrode, an upper insulating tube, a lower insulating tube and a conductive electro...
