More about enDYNA basic

Professional software package for the simulation of diesel and spark ignition engines in real-time.

Applications range from model-based function development and tests of engine control devices through to integration tests in a virtual vehicle and pre-calibration at hardware-in-the-loop simulators.

For sophisticated testing scenarios, enDYNA engine models provide various possibilities of malfunction simulation. The high model accuracy and good parameterization quality of the enDYNA Preprocessing tool allow precise and reliable statements to be made about the behavior of controllers and trouble-free operation.

Our open and modular model architecture implemented in a Matlab/Simulink environment allows easy and straightforward incorporation of your controller algorithms or models of user-specific components. You can make use of the full Matlab/Simulink functionality for simulation control and postprocessing of results. The implementation of typical driving maneuvers (e. g. driving cycles) is supported by open and ready-to-use example scripts and tables.

enDYNA basic engine simulation is available in three versions:

  • enDYNA basic FDI Package
    Simulation of naturally aspirated spark ignition engines, with direct or port fuel injection.
  • enDYNA basic FDITC Package
    Simulation of spark ignition engines, with direct or port fuel injection, with or without turbocharger.
  • enDYNA basic CRTD Package
    Simulation of turbocharged diesel engines with a common rail system or unit injectors.

enDYNA basic can be extended by the following add-ons:

  • Cooling System Advanced
    Two-circuit cooling system with various types of fans, heat exchangers and thermostats.
  • Exhaust System Advanced
    Exhaust system with catalytic converter, secondary air path and lambda sensors.
  • enDYNA Hybrid Toolbox
    Hybrid vehicle library

More about enDYNA Thermo

enDYNA Thermo is a professional software package for the real-time simulation of internal combustion engines.

With its thermodynamic models of the gas path and calculation of the combustion process, enDYNA Thermo engine simulation offers a previously unmatched level of detail in the field of real-time capable engine models. The high accuracy constitutes a crucial add-on for the testing and development of electronic controllers for modern diesel and gasoline engines, e. g. when sensing the crank angle-resolved cylinder pressure.

A physical model of the combustion process and gas dynamics allows for effects of variable valve lift and timing, multiple injections, exhaust gas recirculation and boost pressure control as well as exhaust aftertreatment.

The excellent model accuracy and the high parameterization quality of the enDYNA Preprocessing tool allow precise and reliable statements to be made about the behavior of controllers during ECU testing and development. A very good ECU pre-calibration can already be performed at the simulator, thus saving time and money for field tests with the real engine.

Engine Simulation in Matlab/Simulink

 

All models are fully implemented in Matlab/Simulink. By using a standard simulation environment for model-based design and rapid controller prototyping, we continuously support the development process of controllers from proof-of-concept studies (model-in-the-loop) to verification in hardware-in-the-loop tests. Incorporation of your in-house component models is fast and straightforward. The open and modular architecture makes our models very flexible. Complex supercharging concepts, such as two-stage turbocharging and mechanically or electrically supported turbocharging, can easily be configured.

Simulation packages for diesel and spark ignition engines:

  • enDYNA Thermo CRTD
    Simulation of diesel engines with a common rail system or unit injectors, with or without turbocharger.
    Including exhaust system with oxidation catalytic converters, SCR catalyst and particulate filter.
  • enDYNA Thermo FDITC
    Simulation of spark ignition engines with direct or port fuel injection, with or without turbocharger.
    Including multiple injections, fully variable valve train and Exhaust System Advanced.

enDYNA Thermo can be extended by the following add-ons:

  • Cooling System Advanced
    Two-circuit cooling system with various types of fans, heat exchangers and thermostats.
  • enDYNA Hybrid Toolbox
    Electric powernet system and modular drivetrain to simulate hybrid electric and battery vehicles.
