This paper examines cyclohexyl nitrate (CHN), a chain initiator which can be added to a flame to promote or inhibit it in accordance with the concentration of fuel mixture. The structures of flames containing CHN are examined. Results indicate that CHN raised burning speed, and also influenced the width of the low-temperature zone. CHN inhibits the flame by the narrowing of the reaction zone and the passage of some of the hexane into the hot zone. A model of formulas is derived which explains the numerous and often conflicting published data on the effects of nitrogen oxides on ignition and combustion under various conditions.
