Abstract:
1. A flame ejector device for use in an internal combustion engine having a piston reciprocably mounted in a cylinder, wherein a combustion chamber is provided in the engine cylinder head, wherein the combustion chamber has a volumetric median plane oriented normally to a reciprocation axis of the piston, and wherein a threaded spark plug aperture is provided through the head and into communication with the combustion chamber, said device comprising elongated wall means forming a body having a longitudinal axis, said wall means providing said body with a closed proximal end portion, an open distal end portion and a tubular intermediate portion housing a passage extending generally axially through said body from said open distal end portion to said closed proximal end portion, said distal end portion having internal threads for threadedly receiving a spark plug whereby the electrode elements of the plug will be in communication with said passage, a plurality of flame ejection ports provided through said wall means adjacent said closed proximal end portion and having flame ejection axes which are designedly oriented from parallel to said median plane up to about an angle of 45° diverging therefrom such that flame fronts ejected from said ports will be directed to predetermined areas of greatest fuel-air volumes and whereby said flame fronts will travel maximum prescribed distances through said chamber before impinging on metal surfaces, and external threads on said wall means distally of said ejection ports for threadedly mounting said body in said spark plug aperture, wherein said passage is configured to provide a distal ignition cavity in which said electrode elements are to be positioned, and is further configured to provide an acceleration tube proximally of said cavity and communicating directly with said ejection ports, wherein the ratio of the length of said tube to the length of said cavity is from about 1.0/1.0 to about 12.0/1.0.
