ABSTRACT:
An internal combustion engine system with combustion chamber (11) of the upper-half-clam-shell type in which is generated both swirl and squish and microscale turbulence near the center of the chamber where is located a toroidal gap spark plug (18) fired according to a lean-burn-timing prescription to deliver rapidly moving spark pulses (24) of high power and energy into a very lean reverse stratified mixture further diluted with exhaust gas residual for further reducing NOx emissions while maintaining low HC emissions and high engine efficiency.
