Ever stricter emission legislation and fuel economies are placing ever greater demands on engine design. Therefore it is important to optimize aspects of the whole engine, including after treatment and some mechanisms variables. One-dimensional engine simulation tools have been developed to predict the performance of the whole engine system. These help to understand physical phenomenon within the engine system and help us to study the differences of engine configurations. We show the features of a one-dimensional engine simulation code, and introduce some examples.
