Abstract

The utility model relates to a spark plug for an internal combustion engine, comprising a casing, a ceramic insulator, a binding post and a lateral electrode. A center electrode is designed to be conical. The utility model has the advantages of good starting performance, good ignition performance and fuel saving. The exhaust emission is reduced.

Description

Point discharge sparking-plug

The utility model relates to a kind of ignition plug for I. C. engine, specifically a kind of point discharge spark plug.

Spark plug is as the core component of internal combustion engine operation, from 1860 by Frenchman's invention since, its structure and principle become so far.Traditional common spark plug, its central electrode all is cylindrical, lateral electrode is " ┐ " shape of single-point welding, utilize end plane, the annular angle of cylindrical center electrode to do dispersed arcing (as shown in Figure 2), its spark energy is little, to low-temperature mixed gas, low concentration mist, miscella gas sometimes can not normal ignitions.Along with current aircraft, automobile, the motorcycle vehicles such as (ships) develop to high-speed, high compression ratio and powerful direction, common spark plug is difficult to satisfy the high standard working condition requirement of these used for vehicle internal combustion engines.

The purpose of this utility model provides that a kind of ignition performance is superior, starting performance good, still can produce the spark plug of a branch of axiolitic high-energy spark under the situation of high compression ratio.

The utility model is to realize its goal of the invention by the following technical solutions.A kind of point discharge spark plug comprises housing 3, porcelain insulator 4, binding post 5, lateral electrode 2 etc., does central electrode 1 tapered.

Owing to adopted technique scheme, the utility model has ideally been realized its goal of the invention.Can satisfy the modern high performance internal combustion engine well and not produce advanced ignition when running up, be difficult for knot carbon during low-speed running, the working condition requirement that the arcing energy is big has reached fuel-economizing simultaneously, reduces the effect of toxic emission.

Description of drawings:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the user mode figure of general spark plug commonly used

Fig. 3 is user mode figure of the present utility model

Accompanying drawing 1 has been described an embodiment of the present utility model.It comprises housing 3, porcelain insulator 4, binding post 5, lateral electrode 2 etc. the utility model, and central electrode 1 is done tapered.After the binding post 5 and the high voltage source of engine are connected, between central electrode 1 and lateral electrode 2, produce high voltage flash, its spark is shaped as axiolitic high-energy spark (as shown in Figure 3), makes through the high pressure mixed gas after the atomizing and lights ignition, the driven plunger work done.

Claims

A kind of point discharge spark plug, it comprises housing [3], porcelain insulator [4], binding post [5], lateral electrode [2], it is characterized in that central electrode [1] does tapered.
