Cycle-to-Cycle Variability

open access: yes, 2013
In this chapter we shall analyze how to simulate, within a quasi-dimensional combustion model, the cyclic variability experimentally observed in spark ignition engines. Explicit qualitative comparison with experimental results will be shown. Moreover, we report a nonlinear dynamics analysis of cycle-by-cycle variations in heat release for the simulated
