“…High soot emissions have become the main obstacle restricting development. To this end, scholars from many countries carried out studies by changing the injection strategy of fuel injection multiple times [1][2][3][4], increasing the injection pressure [5], EGR [6,7], biomass gas [8], natural gas [9], hydroammonia fuel and other clean energy application technologies [10,11], and achieved phased achievements. In addition, the use of the oxygen content of fuel has a good effect on the improvement of diesel soot emission.…”

The detailed mechanisms of n-heptane and n-butanol were reduced for the target condition of ignition delay time using the direct relationship diagram method based on error transfer, the direct relationship diagram method based on coupling error transfer and sensitivity analysis, and the total material sensitivity analysis method. The reduced n-heptane (132 species and 585 reactions) and n-butanol (82 species and 383 reactions) were used to verify the ignition delay time and concentrations of the major species, respectively. The results showed that the reduced mechanism has a good prediction ability for the ignition delay time. The predicted mole fraction results of the major species were in good agreement. These reduced mechanisms were combined to finally construct a reduced mechanism for the n-heptane/butanol fuel mixture, which included 166 species and 746 reactions. Finally, the reduced mechanism was used to simulate the HCCI combustion mode, and the results showed that the reduced mechanism can better predict the ignition and combustion timings of HCCI under different conditions and maintain the ignition and combustion characteristics of the detailed mechanism; this indicates that the mechanism model constructed in this study is reliable.
