Abstract
An improved spark ignition engine system producing a large continuous, centrally directed, flow coupled ignition spark discharge through combustion chamber (1), piston (4), inlet system (28/29), spark plug (5), and ignition spark discharge (26) design, and through the location and orientation, with respect to the mixture flow field, of a special design firing end and gap (7/9) of a spark plug fired with a spark discharge of hundreds of watts of power for hundreds of microseconds without spark segmentation or spark break-up by the flow field of up to about 20 m/sec flow velocity, with bulk flow occurring at the spark plug site at most engine speeds including low speeds to produce a very large centrally directed spark-initial flame front kernel which allows for substantial dilution of the mixture and significant reduction in engine cycle-to-cycle variation under most operating conditions of the engine including low speed light load.
