Abstract
A system includes a combustion apparatus for controlling combustion of a fuel and air in a combustion chamber to produce mechanical motion, a source of a chemical species for supplying a chemical species to be mixed with the fuel and air, a control valve for controlling an amount of the chemical species that is introduced from the source into the fuel and the air, and a controller in communication with the control valve to cause the control valve to introduce the chemical species at a flow rate that will cause auto-ignition of combustion between the fuel and the air in the combustion chamber without use of a spark-producing device. The controller may perform operations embodied as program instructions for controlling the system.
