The purpose of this paper is to find a efficient model to simulate the thermal ignition of gasoline-air mixture. First, Detailed chemical reaction model of gasoline-air mixture thermal ignition is discussed. that is, chemical reaction chains of controlling of thermal ignition are got according to the characteristic of gasoline-air mixture; through sensitivity analysis of temperature and species concentration, reaction equations are selected within a certain temperature range; based on the relation between chemical reaction rate of species and thermodynamic parameters, both the rate of species consumption or production and the heat release rate of species chemical reaction are got. Then using low mach, compressible equation as control equations, coupling the detailed chemical reaction model and radiation model, the mathematical model of gasoline-air mixture thermal ignition process, namely comprehensive model,has been established on the basis of unification of chemical kinetics and thermodynamics in this paper. In the end, taking gasoline-air mixture thermal ignition due to contacting with hot wall continuously where temperature is raising in a confined insulation space as example, this paper complete the numerical simulation analysis based on the comprehensive model. The result is demonstrated by the experiment data.The research result shows that the comprehensive model, in which fluid field, boundary conditions and detailed chemical reaction control together is efficient for gasoline-air mixture thermal ignition.

In this paper, we revisit a reaction—diffusion autocatalytic chemical reaction model with decay. For higher-order reactions, we prove that the system possesses at least two positive steady-state solutions; hence, it has bistable dynamics similar to the system without decay. For the linear reaction, we determine the necessary and sufficient condition to ensure the existence of a solution. Moreover, in the one-dimensional case, we prove that the positive steady-state solution is unique. Our results demonstrate the drastic difference in dynamics caused by the order of chemical reactions.
