ABSTRACT:
Computer means for sequential fuel injection including coupling means for applying manifold pressure and speed signals to control fuel injection time in accordance with the product of the signals, at least one of the coupling means including conditioning means having a predetermined non-linear characteristic. In one embodiment, conditioning means having non-linear characteristics are included in both the pressure and speed signal coupling means and each comprises operational amplifier and diode blocking means operative to provide two break point, three slope characteristics. In another, the conditioning means is included in the pressure signal coupling means and a biasing circuit responds to the speed signal to bias the fuel injection time.
This invention relates to computer means for sequential fuel injection and more particularly to computer means operative to provide characteristics closely matching the requirements of a particular engine, to obtain optimum injection of fuel under all operating conditions with a high degree of accuracy.
