Abstract

The utility model discloses a high-energy spark plug, which consists of a terminal screw cap (1), an insulator (2), a main body metal part (3), a sealing thread (5), a sealing washer (6) and a central electrode (7); the metal main body is moved outwards, meanwhile, the original spark plug sealing thread part is removed, threads are machined on the upper portion of a sealing washer, the diameter of each thread is increased, when the threads are subjected to the same force, the threads can be made to be shorter in length, an outer side electrode of a spark plug is directly installed on a cylinder cover, in order to guarantee reliability and durability, three outer side electrodes are installed and evenly distributed around an anode, and therefore the area occupied by the spark plug in a combustion chamber is greatly reduced.

Description

High-energy spark plug

Technical Field

The utility model relates to a high energy spark plug, more specifically say, be a superfine spark plug of automobile-used high energy.

Background

With the development of society, the quality of life is higher and higher, and automobiles also play an increasingly important role in the life of people. This may be accompanied by an increasing pollution problem of the vehicle. The pollution brought by the automobile is mainly caused by the good and bad combustion property of the engine, so the high-energy ultrafine spark plug is designed. The spark plug can improve the combustion quality to a certain extent, and the size of the metal part of the spark plug is greatly limited because the prior old spark plug is limited by the diameter size of the metal part of the main body, the ignition energy and the distance between the inner electrode and the outer electrode which extend into a combustion chamber. Therefore, the high-energy spark plug is designed, the ignition reliability is guaranteed while the minimum size of the high-energy spark plug extending into a combustion chamber is used, the high-energy spark plug can also be used for engines with multiple spark plugs for ignition, and only a small area is occupied.

With a high-energy spark plug it is possible to:

1. by increasing the ignition energy of the ignition coil, the spark plug receives high ignition energy to generate larger spark, thereby ensuring better ignition performance.

2. When the ignition device is used for multi-spark plug ignition, the distribution of each component can be better ensured.

3. When the required energy for ignition is constant, a spark plug of smaller size can be used.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem that the area was taken up in the installation of current spark plug on the engine big, invented novel high energy superfine spark plug.

In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

high energy spark plug be by spark plug's insulator, several parts such as spark plug's copper core, spark plug seal ring, spark plug sealing thread, spark plug terminal screw cap, spark plug metal part constitute its characterized in that:

the working mechanism of the high-energy spark plug mainly comprises a high-energy ultrafine spark plug and a cylinder cover (a side electrode is arranged on the cylinder cover), and only a center electrode is arranged on the high-energy ultrafine spark plug.

When the same ignition energy is provided, a thinner spark plug can be used, the installation space of the spark plug is saved, a plurality of spark plugs can be arranged, multi-point ignition is realized, and the design of an intake valve and an exhaust valve is more excellent and compact.

Compared with the prior art the beneficial effects of the utility model:

1. high energy spark plug can provide the ignition condition of same energy with the diameter more tiny than current spark plug, reduced the area occupied on the cylinder head.

2. High energy spark plug to the reduction of the area that occupies in the combustion chamber top, can ignite for the cylinder with the more reasonable position of many spark plugs.

3. High energy spark plug to the reduction of combustion chamber top area occupied, can increase into, the exhaust valve area, let the loss of taking a breath littleer.

Drawings

The invention will be further described with reference to the accompanying drawings:

FIG. 1 is a cross-sectional view of an assembly diagram of a high energy spark plug according to the present invention;

FIG. 2 is a cross-sectional view of the high energy spark plug of FIG. 1;

in the figure: 1. the engine cylinder cover comprises a terminal screw cap, 2, an insulator, 3, an engine cylinder cover, 4, a main body metal part, 5, a sealing thread, 6, a sealing gasket, 7, a center electrode and 8, an outer electrode.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in fig. 1 and 2, a high voltage current is transmitted to the terminal screw cap 1, passes through the terminal screw cap 1 and the connected metal conductor, and is transmitted to the center electrode 7, and the breakdown mixture reaches the outer electrode 8, and the current ignites the mixture at the time of breakdown. At a certain ignition energy, the corresponding insulator diameter is determined, and the diameter of the spark plug mounting hole required for a suitable high-energy spark plug is smaller than that of a normal spark plug, so that the diameter of the spark plug is reduced compared with that of the normal spark plug. The diameter of the spark plug is relatively reduced by removing primarily the metal portion of the insulator outside.

Claims (1)

1. The high-energy spark plug is characterized by comprising a terminal screw cap (1), an insulator (2), a main body metal part (4), a sealing thread (5), a sealing gasket (6) and a center electrode (7), wherein the sealing thread is designed on the outer side of the sealing gasket through the modification of the main body metal part, and the outer side electrode is directly connected with a cylinder cover.
