Experimental and numerical analysis of nitric oxide effect on the ignition of iso-octane in a single cylinder HCCI engine

Small concentrations of very reactive chemical species such as nitric oxide (NO) have a very important impact on the onset of combustion. In engine applications, this may lead to irregular combustion phenomena in spark ignition engines or contribute to the control of the homogeneous charge compression ignition (HCCI) engines. To numerically analyze and predict the effect of these species, detailed chemical mechanisms are required. However,...
