A nonlinear model of internal combustion engine using Simulink

in this paper, a four cylinder spark ignition engine from throttle to crankshaft is modeled and simulated usingSimulink MATLAB. The surveyed elements including throttle, intake manifold, mass flow rate, compressionstroke combustion and torque generation are simulated and finally, an additional triggered subsystem thatprovides closed‐loop engine speed control via a throttle actuator. The model can be adapted to represent varioustypes of automotive engines with a limited amount of engine data. Preliminary validation results look verypromising.
