Controlled Auto-Ignition (CAI) and Homogeneous Charge Compression Ignition (HCCI) combustion are radically different from the conventional spark ignition (SI) combustion in a gasoline engine and compression ignition (CI) diffusion combustion in a diesel engine. The combination of a diluted and premixed fuel and air mixture with multiple ignition sites throughout the combustion chamber eliminates the high combustion temperature zones and prevents the production of soot particles, hence producing ultra-low NOx and particulate emissions. The use of lean, or more often diluted, air/fuel mixture with recycled burned gases permits unthrottled operation of a CAI/ HCCI gasoline engine
