ABSTRACT:
A flame ignitor for internal combustion engines. This flame ignitor is, in one embodiment, an insert unit to be received in, for example, a conventional spark plug hole of an engine. It is to project into the combustion chamber of the engine a sufficient distance, and at a selected orientation, such that an opening will collect a portion of fuel-rich fuel-air mixture from within the combustion chamber and direct the same toward a spark gap of a spark producing device located in the opposite end of the unit. The device has an elongated secondary chamber proximate the combustion chamber and a primary chamber proximate the spark gap. The opening into the secondary chamber also provides an outlet from the secondary chamber to direct ignited fuel into the engine combustion chamber above the piston head at a high rate of speed to ignite any fuel-air mixture therein prior to the initiation of combustion knock. Extended passageways within the primary chamber automatically provide the timing delays for the respective speeds of the engine.
