WAVE - Combustion and emissions
![](/static/b56fb29726a34da0518d791398830578/402ce/Realis-Simulation_WAVE.png)
WAVE contains advanced combustion models for diesel and spark ignition (SI) engines and includes secondary models specifically for the study of direct injection, SI turbulent flame propagation, engine-out emissions and knock. In addition to in-cylinder models, WAVE also includes a suite of exhaust aftertreatment models. These enable detailed chemical kinetic simulation of advanced emission control technologies to be carried out. WAVE allows the combustion of multiple fuels according to a prescribed burn rate where the combustion can be calculated using a semi-automated heat release analysis process.
