  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To obtain control data having a required inclindation angle for increasing and decreasing the air-fuel ratio with no used of a timer, by providing a means for omitting adding operation according to a predetermined pattern in an air-fuel ratio controlling apparatus for an internal combustion engine.
CONSTITUTION: A slow solenoid 3 and a main solenoid 4 of an engine 1 are controlled by a microcomputer 11, to which are given the output signals of sensors 7W10 for detecting the density of O2, partial vacuum in the intake pipe, water temperature and engine speed, respectively. Further, the computer 11 comprises a means operated by a starting signal produced at a predetermined interval, a means for adding input signals, a means for omitting the adding means according to a predetermined pattern, etc. Therefore, the air-fuel ratio can be controlled according to the value of integration gradient different from that of an ordinary control means in which a timer signal is taken into the main program.
