What are ASM Combustion Engines?
With more than 20 years of experience, the ASM Engine models are ideal for the development and testing of engine and exhaust gas aftertreatment ECUs. They simulate combustion engines with realistic torque, pressure, and temperature curves, fuel injection, and all essential components such as turbochargers and exhaust aftertreatment systems — across various levels of detail. These models act as controlled systems for ECU testing. A soft ECU is included for scenarios where a real ECU is not yet available, e.g., early-stage model development.
Ready-to-use demos are available for different engine variants that support conventional fuels like gasoline and diesel, as well as modern alternatives. The models can be easily customized or extended. For example, a conventional 4-stroke engine can be converted to a 2-stroke engine, CNG (compressed natural gas) can be converted to a hydrogen-fueled engine, and more. This flexibility is made possible by open and fully parameterizable Simulink models.
Typical Application areas:
- Control of engine component, e.g., turbocharger or throttle valve.
- Development of ECU networks, e.g., hybrid drives.
- Optimization of combustion processes, e.g., multiple injection or variable valve control strategies
- Development and validation of emission strategies, e.g., exhaust gas recirculation (EGR) or aftertreatment systems
- Virtual calibration, e.g., parameter studies to optimize and validate engine functions at an early stage
Add-ons for ASM Combustion Engine
Engine Models
To meet diverse application requirements, ASM offers two types of engine models: mean value and in-cylinder models.
Mean Value Models
Mean value models calculate the averaged state variables of the entire engine process for each individual cylinder. Angle-dependent variables such as torque are applied to the mean values of the selected cylinder through modulation. These models offer excellent real-time performance and are accurate enough to provide plausible signals to conventional engine control units, enabling the testing of ECU functions and diagnostic capabilities.
In-Cylinder Models
In-cylinder models simulate thermodynamic and gas exchange processes within the cylinder, in synchronization with the crankshaft. These models are essential for control units that evaluate cylinder pressure, fuel injection strategy, or lift and timing of intake and exhaust valve operations.
Model Parametrization and Validation
ASM Engine demos provide a tool chain for model parametrization and validation.
- ModelDesk Processing: an integrated parameterization workflow for ASM powertrain model in ModelDesk. The processing routines are based on the MATLAB® programming environment. Sophisticated error-handling procedures support the users during parameterization. Typical use cases include engine parameterization based on real test bench measurements.
- ASM Testbench: a MATLAB-based tool for validating the simulation behavior of powertrain models. It provides a guided workflow to compare the simulation results with a real testbench measurement.
