ABSTRACT:
A system capable of accommodating extremely lean mixtures and operating with greatly reduced engine emissions and good fuel consumption. The system is applicable to "L" head, "F" head and "OHV" engines. A combustion chamber is used which encloses at a broad end a deep pocket offset from the cylinder and in which at least part of one valve is disposed. A narrow shallow end of the combustion chamber lies directly above the piston and is surrounded on three sides by a narrow but long squish area. No restriction exists between the two portions of the chamber. A first spark plug is disposed to fire into the chamber at a point in the narrow end of the chamber overlying the piston. A second spark plug fires into the chamber at a point spaced from the cylinder but adjacent the valves, in or near the broad end of the chamber. Means are provided to produce sequential firing of the spark plugs.
