Ignition plug for internal combustion engine

Abstract

The present invention, for the purpose of accomplishing the above purpose, provides an ignition plug for an internal combustion engine, comprising: a main cell having a groove formed in a predetermined position, the groove being formed annularly on the outer peripheral surface of the main cell; an auxiliary cell that surrounds the main cell, a screw portion being formed on the outside of the lowerportion of the auxiliary cell, and the auxiliary cell comprising a bending portion, the upper portion of which is bent towards the main cell and thereby engages with the groove; a ring cover interposed inside the bending portion; a primary combustion chamber formed inside the lower portion of the auxiliary cell so as to contain an electrode that generates flames; and an orifice valve coupled to the other end of the auxiliary cell so as to surround the electrode, wherein the center portion of the orifice valve protrudes towards the interior of the auxiliary cell, and at least one ejection holeis formed thereon. The present invention, which is configured and operates as above, is advantageous in that a guide portion is formed inside the plug orifice valve such that explosion flames are diffused and ejected into the main combustion chamber, through the primary combustion chamber, more quickly and rapidly; accordingly, the rate of combustion remains high up to the end of the main combustion chamber such that, by enabling retarded ignition, the combustion performance is improved; and the combustion efficiency also increases, making it possible both to improve the fuel efficiency and to reduce the exhaust gas.

Description

technical field [0001] The invention relates to a spark plug for an internal combustion engine, in particular to providing a spark plug for an internal combustion engine with a stable structure by preventing natural ignition in the spark plug, improving combustion efficiency, and improving the structure. Background technique [0002] For a high-performance internal combustion engine using gasoline with a high Xinwan value, in order to achieve the combustion efficiency of the required appropriate output power, according to the different speeds of the internal combustion engine, at low speeds before the top dead center (TDC) (BTDC) -5゜~-6゜(± ) angle ignition, as the speed of each internal combustion engine increases, the advance ignition (Advance Ignition) time is also carried out at an angle of 50 ゜ (±) before the top dead center to achieve the maximum output power of the internal combustion engine. [0003] According to the content disclosed in Korean Intellectual Property O...

Problems solved by technology

[0004] In the patent Fig. 1 that has been applied for, a circular injection hole for the fluid to enter and exit is formed on the spark plug (100). Compared with the traditional spark plug, although the combustion time of the internal combustion engine can be shortened, there is a problem that a small amount of explosion flame enters the combustion chamber
