Self-ignition nitrogen oxide effect

Nitrogen Oxide Effect on Hydrogenous Mixture Self-Ignition... 

Interest in the nitrogen oxide effect on hydrogenous mixture self-ignition has been brought up by some conclusions made in [53] that compounds like NOx (for example, NO) are inhibitors of self-ignition at temperatures lower than 1,100 K and pressures higher than 0.03 MPa. The predictions [53] were contradicted by measured data in [54]. The pressure and temperature zones presented in [53, 54] and supplemented by data obtained in [55] are outlined in Fig. 6.13. It is seen that most data were measured in a zone of limited practical use.
