WAVE - Combustion and emissions
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.
