Document Type and Number:
Japanese Patent JP7093480
Kind Code:
B2
Abstract:
Disclosed are a flame-ejecting spark plug, and an internal combustion engine and an automobile having same. On the basis of a conventional spark plug, a space near to an electrode is closed to form a cavity (10), an end face is provided with at least one first hole (11), and a side face is provided with at least one second hole (13). A mixture of air and fuel enters the cavity (10) through the first hole (11) and the second hole (13). Electric discharge between the electrodes produces a spark igniting the combustible gas within the cavity (10), and the flame extends in the cavity (10) and the temperature and pressure rise. The flame is ejected from the first hole (11) and the second hole (13) to form a plurality of columnar flames, and the flame penetrates the combustible gas in a combustion chamber and a cylinder to realize stereoscopic ignition, large-area ignition and high-energy ignition of the combustible gas in the combustion chamber.
