IGNITE - Emissions aftertreatment systems modelling
![](/static/f9280a330352763ed0bc1b998c816f72/cb155/ignite-hero_1152x654.png)
IGNITE contains a comprehensive library of 1-D emissions aftertreatment models. It enables users to predict the tailpipe emissions of various engine exhaust system configurations. Hence it also helps to evaluate the impact of the vehicle-level control on the desired emission reduction. The simulation time for predicting vehicle tailpipe emissions for a single simulation experiment is typically completed in about 20 minutes over the WLTC cycle corresponding to 30 mins (1800 sec), faster than real-time.
