ASM Gasoline Engine Basic
Real-time gasoline engine simulation model
Basic mean value engine model with combustion torque modulation.
- Open MATLAB®/Simulink® model
- Real-time simulation and offline simulation
- Mean value engine model with combustion torque modulation
The physical engine characteristics are represented by a mean value engine model with crank-angle-based torque generation, dynamic manifold pressure, temperature calculation, and an injection model. 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.
