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. Computational results are compared with experimental data. Then, a factor generating the cyclic variations is revealed, which leads to an effective way to control instability of combustion at very lean burning conditions.
