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

Abstract

PURPOSE: To correct air-fuel ratio in response to engine status and to attempt purification of exhaust gas, by means of changing, in response to engine status, the impedance between the integrator and comparator which compares output from oxygen density detector with the predetermined value, and also by means of changing integral constant of the integrator.
