Abstract: An air-fuel ratio control system of a multi-cylinder internal combustion engine provided with a throttle valve and opening characteristic control means, which system performs feedback control of an air-fuel ratio based on an output of a sensor detecting an air-fuel ratio of exhaust gas and is capable of performing more accurate air-fuel ratio control, is provided. In the feedback control, the relationship of the output of the sensor and a feedback value is corrected based on a feedback learning correction value learned and determined based on the output of the sensor during the feedback control, and, when newly learning the feedback learning correction value, the intake air amount is controlled by only the throttle valve.

Abstract: The multiple gas detection device 1 comprises: a first cell part provided with a first electrochemical cell 51; a second cell part provided with a second electrochemical cell 52; a third cell part provided with a third electrochemical cell 53; an inlet diffusion controller 15 controlling diffusion of measured gas; and a measured gas chamber 30 into which the measured gas flows through the inlet diffusion controller 15. The first cell part is configured to selectively detect a concentration of NO x or ammonia contained in measured gas in the measured gas chamber 30. The second cell part is configured to discharge oxygen contained in measured gas in the measured gas chamber 30 and convert NO 2 and ammonia contained in measured gas in the measured gas chamber 30 to NO. The third cell part is configured to detect a concentration of NO contained in measured gas in the measured gas chamber 30.
