To study diesel fuel auto-ignition in an O2–CO2 mixture, a TZ (temperature zone) model is proposed. The effect of O2 and CO2 on reaction rate is considered. The relationship between temperature and ignition delay time is obtained. Different reduced mechanisms based on steady-state assumptions are applied in three temperature zones (T ≤ 800 K, 800 K < T ≤ 1100 K, T > 1100 K). The TZ model is coupled to KIVA-3V code for simulation calculations. To support the simulations, a constant-volume combustion bomb test bench is set up to visualize diesel fuel auto-ignition in air (21%O2–79%N2), a 53%O2–47%CO2 mixture, and a 61%O2–39%CO2 mixture. Ignition delay time and the flame image in these three conditions are compared and analyzed. Then the flame temperature contour and the flame lift-off length in a 53%O2–47%CO2 mixture and a 61%O2–39%CO2 mixture are analyzed. The results show that diesel fuel auto-ignition can be achieved in the tested O2–CO2 mixture. The TZ model can predict the auto-ignition characteristics of diesel fuel in a 53%O2–47%CO2 mixture and a 61%O2–39%CO2, with errors of 12% and 10%, respectively. In these two conditions, the ignition delay time and flame lift-off length are shorter than they are in air.

A large portion of the literature about the use of hydrogen as a fuel in air-breathing reciprocating engines is devoted to the problems of auto-ignition and knock. Operation with oxygen-enriched air or pure oxygen, which in principle can reduce or even eliminate the production of oxides of nitrogen, is expected to be potentially more troublesome in this respect. The paper describes an analytical approach, incorporating detailed chemical kinetics, to the combustion of H2-O2-N2 mixtures in a reciprocating engine. The role of various operating parameters was determined primarily in relation to the length of the ignition delay and the associated peak values of cylinder pressure and temperature. Also, the extent of production of oxides of nitrogen in the exhaust was examined in terms of cycle parameters and the oxygen index of the charge.
