Research on Transient Fuel-Film Compensation Control Strategy for a Port-Fuel-Injected Engine
The fuel-film evaporation model and transient fuel-film compensator model were established. By virtue of Simulink, the validity of above models were verified. The square wave perturbation method was introduced. Basing numerous calibration, the fuel-film compensation strategy including zoned compensation and damping factors ware proposed. This new strategy can compensate in-cylinder fuel fluctuation effectively during transient conditions.
