Patent ·
OSTI ID:6748525

A flaming engine system for an internal combustion engine of the Otto-cycle type comprised of primary and secondary pre-ignition chambers serially interposed between an engine cylinder and a spark plug, and self-actuated of means metering high combustible fuel into the primary pre-ignition chamber. The flame commenced in the primary pre-ignition chamber is enhanced and promoted as it is caused to pass into the secondary pre-ignition chamber, then through geometrically designed openings and into the cylinder for ignition of the base-air-fuel mixture contained within the cylinder.
