- Summary:
- AbstractThis study presents a preliminary application of Large-Eddy Simulations (LES) of a speed transient performed on a motored single-cylinder engine. The numerical setup follows a methodology which has been validated and optimized for stabilized operating points in previous work, and adapted to run a speed transient of 31 cycles, from 1000 to 1800 rpm. Analysis of the results contributes to characterize the impact of the transient on the engine charge, tumble motion and velocity distribution. These simulations, which have never been performed in the past (to the best of our knowledge), represent a decisive step towards modeling and understanding transient in GDI engines, and particularly their impact on soot particle emissions in real driving conditions
