Analysis and modeling of transient operation of ... - Ricardo

Philosophy, Requirements
• Due to the relatively high complexity of processes to be
examined a consistent methodology for conducting testing
and simulations is highly demanded
• Engine simulation does not necessarily aim to reduce or
replace experiments, but to complement them by providing
information on variables that are difficult to measure at the
relevant time scale
• The model should preserve the essential in-depth physical
information but also provide useful results from an engine
control perspective
usually distinct approaches – involve different time scales
