Technical Examples

A spark plug system includes a center spark plug and a plurality of peripheral spark plugs, the spark plugs extending into a ridge-roof type combustion chamber of an internal combustion engine from the inner surface of a cylinder head and being disposed approximately on the ridgeline of the ridge-roof. The amount by which the center plug projects into the combustion chamber from the inner surface of the cylinder head is different from the amount by which each of the peripheral plugs projects into the combustion chamber from the inner surface of the cylinder head, whereby the time in which the flame propagation of the center plug reaches the flame propagation of the peripheral plugs is delayed.
