Abstract

A model for early flame kernel development that allows for individual stochastic realizations is proposed. The following concepts are used in the model: The flamelet concept, the flame broadening concept, the concepts of flame quenching by turbulence and early flame kernel extinction due to heat loss into the spark electrodes. The model simulates both cycle-by-cycle variation and lean misfire limit in an SI engine. Comparison between numerical results and measurements of spark-ignited kernels under a variety of conditions verify the validity and universality of the model.
