ASM Diesel Engine
Real-Time-Capable Simulation Models for Diesel Engines
ASM Diesel Engine is a mean value engine model with torque modulation.
- Open MATLAB®/Simulink® model
- Real-time simulation and offline simulation
- Mean value engine model with combustion torque modulation
The tool is suitable to be used in safety-related development projects according to ISO 26262:2018 for any automotive safety integrity level (ASIL).
ASM Diesel Engine is a mean value model that simulates the behavior of a diesel engine via crank-angle-based torque modulation. It considers the temperature and dynamic manifold pressure and has several fuel injection models. A soft ECU is included for scenarios where a real ECU is not available, for example, in offline simulation. To simulate the engine in an automotive system (car or truck), the engine model incorporates a longitudinal drivetrain model with manual and automatic transmission, a clutch, a torque converter, a starter, and a test bench mode. Models for the environment and driver complement the virtual powertrain.
