标题： A Numerical Study of a Simple Stochastic/Deterministic Model of Cycle-to-Cycle Combustion Fluctuations in Spark Ignition Engines

摘要： 我们考察了一个简单的燃料-空气燃烧模型，在间接喷射的火花点火（SI）发动机中。 在我们的两流体模型中，由于燃料供给量的随机波动，循环序列中的燃烧燃料质量发生变化。 我们证明了这些波动的小振幅会显著影响燃烧过程的稳定性，这强烈依赖于空燃混合物的质量。 在贫燃极限下发现了最大的影响。 还讨论了燃烧过程中非线性可能产生的影响。 显示英文摘要

摘要： We examine a simple, fuel-air, model of combustion in a spark ignition (si) engine with indirect injection. In our two fluid model, variations of fuel mass burned in cycle sequences appear due to stochastic fluctuations of a fuel feed amount. We have shown that a small amplitude of these fluctuations affects considerably the stability of a combustion process strongly depending on the quality of air-fuel mixture. The largest influence was found in the limit of a lean combustion. The possible effect of nonlinearities in the combustion process has been also discussed.
