Abstract
PURPOSE: To prevent overshooting of actuator, and generation of black smoke by preparing means to set predetermined upper limit to the changing rate of instruction signal to the actuator which drives fuel injection control mechanism.
CONSTITUTION: Input accelerator position signal IS1 and unit pulse IS3 to basic injection volume arithmetic circuit 101, to calculate basic injection and output it. Further air density signal IS8, and fuel temperature signal IS13 as well as above stated signals IS1 and IS3 are inputted to compensation volume calculation circuit 102, to calculate injection compensation volume and output it. Output S2 and S3 of each arithmetic circuit 101 and 102 are added by adding circuit 103, to obtain actual injection volume signal S4. On the other hand, previous fuel injection volume control signal OS4 is stored in the storing circuit 104, the difference of this OS4 and above S4, ΔS, is calculated by subtraction circuit 105, and the difference ΔS is compared with the upper limit ΔS0 by a comparator 106. When ΔS<ΔS0, signal S4 from switching circuit 107 is outputted to the servo circuit 109.
