ABSTRACT:
A feedback control system for an internal combustion engine, particularly as utilized in an outboard motor. An oxygen sensor outputs a signal indicative of the fuel-air ratio for controlling the charge-forming system of the engine to maintain the desired fuel-air ratio. A series of filters, each tuned for a different frequency and a different engine speed, are interposed between the sensor and the control for reducing the effect of noise.
