ABSTRACT:
Disclosed is a method of igniting in an internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber which are interconnected to each other by a connecting passage. The spark gap of the spark plug is located in the connecting passage. A ratio of the volume of the auxiliary combustion chamber to the cross-sectional area of the connecting passage is set in the range of 5 through 15 cm for creating a strong swirl motion of the combustible mixture in the auxiliary combustion chamber at the time of the compression stroke. The length of the continuance time of the discharging arc is set at approximately 1 m sec.
