FUEL INJECTION TIMING CONTROL DEVICE

摘要

PURPOSE:To enhance the indicial responsiveness and control accuracy of fuel injection, by delivering a drive signal to an injection timing regulating device in accordance with an estimating term which is computed based upon a change in a correcting term, a basic term or a desired fuel injection timing. CONSTITUTION:A basic term computing means 10'A computes a basic term in accordance with signals from a running condition detector 4' and a fuel injecting condition detector 5'. A correcting term computing means 10'C computes a correcting term in accordance with the error of an actual fuel injection timing from a desired fuel injection timing. Further an estimating term computing means 10'B computes an estimating term in accordance with a change in the basic term or the desired fuel injection timing, and an output computing means 10'D delivers a drive signal to a fuel injection timing regulating means 3'. With this arrangement, the indicial responsiveness and control accuracy of fuel arrangement, the indicial responsiveness and control accuracy of fuel injection may be enhanced.
