Abstract: This article mainly introduces equilibrium stoichiometric modeland solution to the combustion of water-fuel mixtures in internal combustion engine. It brings out the program calculation and eXperimentresults of the effects of water-fuel rat-io(W/F) and air-fuel ratio(A/F) on the equilibrium concentration and the ther-modynamicquality parameter of the combustion gas under adiabatic conditions.

Key words: internal combustion engine, combustion, water-fuelmixtures

摘要： 本文着重介绍了内燃机含水可燃混合气燃烧组分浓度的化学平衡计算模型和解法。给出了在绝热状态下混合气含水量、过量空气系数对燃烧组分浓度、热力性质参数的影响的程序计算结果和试验结果。
