ASM Gasoline Engine InCylinder is a real-time-capable gasoline 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.
ASM Gasoline Engine InCylinder is an open Simulink model for developing and testing electronic control units (ECUs) with engine management based on the in-cylinder pressure. The model simulates in-cylinder pressure in real time by means of a zero-dimensional thermodynamic approach. The gasoline combustion process is reflected by considering ignition delay, combustion duration, and typical burn function trajectories. In the combustion process, gas exchange simulation is related to the lift of the intake and exhaust valves. The gas-dynamic behavior of the air path and exhaust path is implemented as a mean value system with manifold pressure, temperature, and mass calculation. The inlet and exhaust valves are modeled as isentropic orifices. They can handle variable valve timing (VVT), variable valve lift (VVL), and the simulation of engines without a camshaft. To simulate the engine within an automotive system (car or truck), the engine model incorporates a basic longitudinal drivetrain model. Models for the environment and driver complement the virtual powertrain.
