The reduction of the NOx emissions in engines is of critical interest for the automotive industry. The main formation pathway of NO at high temperatures is the Zeldovich mechanism which rate of the limiting initiation step N2+O->NO+N is strongly increasing with temperature. The formation of thermal NO comes then from the local conjunction of high temperature and high concentration of atomic oxygen. In the present work, two optical diagnostics are studied to map the temperature and NO formation rate.A thermometry technique based on Two-Line Atomic Fluorescence of seeded indium atoms in a two-dimensional planar imaging mode was performed. The two transitions were not excited successively. The reference temperature measurement is obtained in a...
