Model spark ignition and compression ignition engines for intake and exhaust flows, emissions and torque assessment
The Modelica-based Engine library is capable of modelling both Spark Ignition and Compression Ignition engines and supports different levels of fidelity. The VeSyMA Engine provides foundation for the platform which means it includes the interfaces, templates and 1D components that allow for representative evaluation of vehicles with reduced complexity models.
The VeSyMA Engines library has been designed to work with common engine architecture templates. This enables quick model set-up and ensures a consistent layout for a variety of engine architectures. The Mean Value models predict the cycle averaged intake and exhaust flows, emissions and torque. The Crank Angle Resolved models predict the complete cyclic intake and exhaust flows and torque.
Benefits
Easy to customize to investigate new technologies like Variable Camshaft Timing and Atkinson cycle engines
Add turbochargers, superchargers and related components such as intercoolers
Easy to switch from mean value and crank angle models through common templates
It is possible to simulate surrogate versions of Crank Angle Resolved Engine Models (CAREM) and Mean Value Engine Models (MVEM)
User can perform thermal analysis of the models
Standard engine templates are available. These can be used to build engines of different architectures
Engine Control Unit model is available to control CAREM and MVE Models
Highlights
Support modelling engines as Mean Value models for fast simulation and Crank Angle Resolved models for detailed analysis
A single model including intake and exhaust flow and mechanical dynamics
Spark Ignition and Compression Ignition engines
Supports naturally aspirated and forced induction (turbochargers and superchargers)
Uses standard Modelica connectors to ensure compatibility with other automotive model libraries
Uses the Rotational3D library developed by Claytex for efficient simulation of rotating MultiBody systems
