Simulation of premixed combustion in a spark-ignition engine


Basics

For the simulation of combustion in a direct-injection spark-ignition engine a new model of the propagation of the premixed flamefront is used. The aim here is to first investigate the interaction of flow and turbulence with flame propagation. In a second step the accumulation of pollutants (soot, NOx) is evaluated via adequate models. Optimisation strategies regarding layout of combustion space and flow duct are to be supported by the numerical models.
