Cycle-Resolved Computations of Stratified-Charge Turbulent Combustion in Direct Injection Engines

Cyclic variations of stratified-charge turbulent combustion in direct injection gasoline engine can be simulated over ten continuous cycles based on the multi-level formation for the compressible Navier–Stokes equation and also a spray model. Computationa
