WAVE - combustion and emissions

WAVE applications

Combustion and emissions

WAVE contains advanced combustion models for both diesel and 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 allow detailed chemical kinetic simulation of advanced emission control technologies. WAVE allows combustion of multiple fuels according to chosen burn rate, where the combustion can be calculated using a semi-automated state-of-the-art heat release analysis process.
