Problems solved by technology

The performance of the spark plug directly affects the performance of the engine. If the spark plug cannot properly ignite the air-fuel mixture in the combustion chamber, at least part of the fuel in the combustion chamber will not be combusted, which will lead to loss of engine power, reduction of fuel combustion efficiency and carbon dioxide. Increase in Hydrogen Compound Discharge

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the preferred embodiment of a kind of improved spark plug of the present invention is described in detail:

[0013] figure 1 What is shown is a structural schematic diagram of an improved spark plug of the present invention. Like the conventional spark plug, the improved spark plug is installed on the cylinder head of the internal combustion engine for use. The improved spark plug mainly includes a shell 1 and an insulating ceramic core 2 . Shell 1 is made of steel, such as figure 2 As shown, the upper end of the shell 1 is cylindrical, and the outer wall of the cylinder is provided with threads 14, which are used to seal the spark plug on the cylinder head, as image 3 As shown, the lower end of the shell 1 has a hexagonal tail 15 to adapt to the twisting of the pipe wrench.

[0014] The inside of the casing 1 is a cavity that penetrates up and down. The upper half of the cavity is a fire-spraying chamber 11 , and th...

Abstract

The invention relates to a part of an internal combustion engine, in particular to an improved spark plug. The improved spark plug comprises a case and an insulation porcelain core fixedly arranged in the case, wherein a center electrode is arranged in the insulation porcelain core, the upper end of the center electrode extends out of the insulation porcelain core to form a discharging tail end, the discharging tail end is positioned in a flame jetting cavity, a grounding electrode approaching to the discharging tail end is arranged in the flame jetting cavity, the case is provided with the flame jetting cavity, and the flame jetting cavity is provided with a gradually gathered opening, and the periphery of the opening is provided with flame jetting holes communicated with the inside and the outside of the flame jetting cavity. A discharging ignition device consisting of the center electrode and the grounding electrode is arranged in the flame jetting cavity, the flame jetting cavity is provided with the gradually gathered opening, and the periphery of the opening is provided with the flame jetting holes, so in the structure, the jet flame is powerful, meanwhile, the flame jet range of the flame is wide, and the efficient ignition environment is created.

Description

technical field [0001] The invention relates to a component of an internal combustion engine, in particular to an improved spark plug. Background technique [0002] Spark ignition engines ignite the air-fuel mixture in the combustion chamber via a spark plug. The performance of the spark plug directly affects the performance of the engine. If the spark plug cannot properly ignite the air-fuel mixture in the combustion chamber, at least part of the fuel in the combustion chamber will not be combusted, which will lead to loss of engine power, reduction of fuel combustion efficiency and carbon dioxide. Increased emissions of hydrogen compounds. Contents of the invention [0003] The present invention provides an improved spark plug with high ignition efficiency. In order to realize the above-mentioned purpose of the invention, the present invention adopts the following technical means: [0004] An improved spark plug includes a shell and an insulating ceramic core fixedly ...
