  • Patent number: 8915227
    Abstract: A spark plug of internal combustion engine is disclosed. The spark plug includes: a main body having main thread on lower outer side; an insulator mounted in a hollow portion of the main body; a ground electrode to correspond to a central electrode extending from the lower end of the terminal rod; a primary combustion chamber forming shell having female thread to be screw-coupled with the main thread, male thread to fix a combustion chamber, and an ejection hole; the primary combustion chamber formed between the main body and the primary combustion chamber forming shell and having changeable volume; and a heat exchange member disposed between the main body and the insulator to exchange heat caused by flame and to block leak of volatile gas; wherein the main ejection hole has a single main ejection hole and at least two auxiliary ejection holes formed around the main ejection hole.

  • Patent number: 8127741
    Abstract: An ignition plug for an internal combustion engine is provided, which includes a pre-combustion chamber cell (150) and at least three exhaust nozzles (160, 170). The pre-combustion chamber cell (150) is disposed to surround a pair of electrodes (140b) in the lower portion of a main cell (110) and is formed in the inner portion where the electrodes (140) are contained. Meanwhile, a circular main exhaust nozzle (160) through which a fluid goes in and out is disposed in the central region of the pre-combustion chamber cell (150). The ignition plug enables the whole engine to have a quick combustion speed. As a result, a more reliable improvement of a combustion performance can be obtained. Also, a fuel-to-air ratio can be enhanced, and an exhaust gas reduction effect can be obtained.
