ASM Diesel Engine InCylinder is a real-time-capable diesel engine model with in-cylinder pressure and temperature simulation.
Using models with physical precision to simulate combustion engines in real time; e.g. in-cylinder pressure, temperature, gas mass flows.
The ASM Diesel Engine InCylinder Model is an open Simulink model for developing and testing electronic motor control units that evaluate the in-cylinder pressure. The model uses a zero-dimensional thermodynamic approach to simulate the in-cylinder pressure in real time. The diesel combustion process simulation can handle multiple injection patterns such as pre-, main- and post-injection. During the combustion process, the gas exchange simulation depends on the lift of the intake and exhaust valves. The gas dynamical behavior of the air path and the exhaust path is implemented as a mean value model with the manifold pressure, temperature, and mass calculation. Intake and exhaust valves are modeled as isentropic orifices. By default, the exhaust path has a diesel oxidation catalyst and a diesel particulate filter. To simulate the engine in an automotive system (car or truck), the engine models incorporate a basic longitudinal drivetrain model. Models for the environment and driver complement the virtual powertrain.
