Abstract
An air/fuel mixture is ignited in an internal combustion engine by receiving the air/fuel mixture as an incoming air/fuel mixture flow from a main combustion chamber of the internal combustion engine into an enclosure adjacent the main combustion chamber. The enclosure defines a first chamber enclosing first and second ignition bodies and the enclosure defines a second chamber adjacent the first chamber and connected to the first chamber via a passage. A portion of the air/fuel mixture received in the enclosure is directed toward an ignition gap between the first and second ignition bodies and another portion is directed into the second chamber. The air/fuel mixture is then ignited in the ignition gap, and flame from combustion in the first chamber is ejected into the main combustion chamber. Then, flame from combustion in the second chamber is ejected into the main combustion chamber.
