Fenimore (Prompt) Mechanism
- Prompt mechanism refers to the
 which are formed very quickly by interaction of active hydrocarbon species derived from fuel with nitrogen and oxygen.
- They are generally not observed in flames of non-hydrocarbon flames.
- They cannot be formed by just heating nitrogen with oxygen.
- During initial phase of combustion, the radials with carbon atom react with
 to produce N.

- This reaction is the main path which dictates the rate at which radical ‘N' is formed.
- The radical ‘N' can also be formed by the following reaction.

- When the equivalence ratio is less than 1.2, HCN can be converted to NO as follows,
