3.7.2 Engine Dynamics Library
Engine Dynamics Library is a new library that a framework for combustion engine system
modeling, simulation and analysis, including the complete gas exchange. The library is well
suited to represent transient engine response and related engine control. Applications
include control design with the purpose of reducing emission transients from the engine,
transient exhaust condition modeling for optimum EATS operation conditions, and engine
response dynamics.
The Engine Dynamics Library utilizes a mean value combustion model for torque, charge
flow and exhaust condition modeling. Pressure and thermal dynamics of the complete air
gas exchange process can be studied. Several turbo charger and EGR configurations can be
modeled, including variable geometry turbine designs.
