Electronic injection fuel delivery control system |
摘要 |
A system for controlling the fuel delivery of an electronic injection system, whereby a processing unit determines the amount of fuel to be injected for achieving a substantially correct stoichiometric air/fuel ratio; which value is subsequently corrected by a coefficient calculated by integrating a signal comprising a signal supplied by a sensor located in the exhaust manifold of the engine and presenting a transfer function comprising a nonlinear characteristic and a delay seriously affecting system response. The system also comprises a processing unit for simulating the transfer function of the engine-sensor system and generating a signal simulating the signal actually produced by the sensor but minus the delay introduced by the sensor and the system; which signal is used for producing a correction signal which is added to the signal generated by the sensor for compensating the delay and so improving the dynamic response of the system as a whole.
