Abstract (en)

[origin: EP0524575A2] An adaptive electronic injection fuel delivery control system wherein a processing unit (10) receives and processes input signals proportional to the air intake pressure (P) and temperature (T) in the manifold of the engine, and supplies an output value (Qb) indicating the amount of fuel to be injected for achieving a substantially correct stoichiometric air/fuel ratio. The above value (Qb) is subsequently corrected by two coefficients (K02 and Kad), the first calculated in closed-loop manner by integrating the difference between the signal generated by an exhaust sensor (20) and a reference voltage value (Vst), and the second by interpolating a set of values comprising the inverse of the air intake value (1/(Q)), and previously measured values of the K02 parameter. <IMAGE>
