Initial experiments on a setup for IC engine modeling and control research

The experimental setup has been developed in order to validate different control-oriented engine mathematical models and to verify different engine and powertrain control methods. The setup is equipped with a Briggs & Stratton gasoline engine, a high-bandwidth engine-load servosystem, an electronic throttle system, different sensors, and a control computer. The initial experiments were carried out in order to obtain the standard engine static curves, like the induction map, torque vs. engine speed and torque vs. manifold pressure curves. These experimental data were employed to form three data maps, which were afterwards used as a part of engine mean value (low frequency) mathematical models. These are throttle map, port flow map, and torque map. Tip-in-tip-out dynamic responses, and a description of simulated engine model are given in the paper.
