ABSTRACT:
Torch jet ignition is used to assist conventional spark ignition. A small (0.5-1 cc) chamber in a spark plug has an orifice (0.1-0.2 cm diameter) adjacent the spark gap to emit a torch jet into the main combustion chamber to enhance the combustion. The combustion is initiated by the conventional spark in the combustion chamber and the combustion ignites the torch jet. In another embodiment, two spark gaps in series are used, one in the main combustion chamber and one in the torch chamber.
