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.
