Patent ·
OSTI ID:5004448

An air intake side secondary air supply system for an internal combustion engine having an intake air passage with a carburetor and a throttle valve and an exhaust gas passage is described comprising: an air intake side secondary air supply passage leading to the intake air passage downstream from the throttle valve; a solenoid valve disposed in the air intake side secondary air supply passage; first sensor means disposed in the exhaust gas passage for sensing the concentration of an exhaust gas component of the engine and producing a sensor output signal indicative of the concentration; further sensor means for monitoring a plurality of parameters indicative of the operating state of the engine and operative to produce output signals indicative of the magnitude of the parameters; and control means connected to each of the sensor means for effecting feedback control of the air-fuel ratio of the mixture to be supplied to the engine.
