Cycle-resolved Computations of Stratified-charge and Homogeneous-charge Turbulent Combustion in Direct Injection Engines 2011-01-1891
Cyclic variations of stratified-charge and homogeneous-charge turbulent combustion in direct injection gasoline engine can be simulated over five continuous cycles based on the multi-level formation for the compressible Navier-Stokes equation and also a spray model. Computational result is compared with an experiment. 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.
