Control Strategy & Calibration of Fuel Film Compensation in the Transient Conditions

Abstract:

Article Preview

Three reasons of the deviation of the fuel injection quantity for the electronic fuel injection (EFI) motorcycle engine during the transient conditions were analyzed, including the presence of fuel injection dead time, the engine load measurement deviation and the existence of fuel film attached to the inlet pipe wall. The control strategy of fuel film compensation was studied at conditions of starting, acceleration and deceleration, which was based on the changes of engine velocity, inlet air pressure and inlet air temperature. During the transient condition, the basic fuel film compensation and correction coefficient were calibrated at motorcycle dynamometer, and the modified fuel film compensation MAP were achieved correspondingly, in order to keep the excess air coefficient stable.
