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.
Application Areas
ASM Engine models cover a wide range of application areas. These include the control of engine components such as turbocharger or throttle valve, control unit networks such as hybrid powertrains, or advanced combustion chamber processes such as multiple fuel injection or variable valve train strategies.
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.
