Air-fuel ratio control system for internal combustion engines
Patent
·
OSTI ID:7274159
The design is given of an air-fuel ratio control system for an internal combustion engine. An oxygen concentration detector is mounted in an exhaust manifold, and an air-fuel ratio discriminating circuit compares the detected signal with a predetermined value to produce a discrimination signal. An injection command circuit is connected to the air-fuel ratio discriminating circuit and controls a fuel-injection electromagnetic valve mounted in the intake manifold.
