    摘要: A control system for a variable-cylinder internal combustion engine, which is capable of attaining excellent fuel economy by executing a partial-cylinder operation mode as long as possible, while suppressing vibration and noise during the partial-cylinder operation mode. A control system switches the operation mode of a variable-cylinder internal combustion engine between an all-cylinder operation mode in which all of a plurality of cylinders (#1 to #3, and #4 to #6) are put in operation, and a partial-cylinder operation mode in which some (#1 to #3) of the plurality of cylinders are deactivated. During the partial-cylinder operation mode, the control system 1 calculates a degree-of-continuation parameter SDTQCSNH indicative of a degree of continuation of a state where detected load TQECMDF on the engine is within a predetermined range of load between a first reference value TQCSNH and a second reference value TQCSEH smaller than the first reference value (steps 10 to 13), and determines whether or not the operation mode should be switched to the all-cylinder operation mode, based on the degree-of-continuation parameter SDTQCSNH (step 14).

    摘要: An air-fuel ratio sensor deterioration-detecting system for an internal combustion engine includes a catalytic converter arranged in the exhaust system, first and second air-fuel ratio sensors arranged in the exhaust system at respective locations upstream and downstream of the catalytic converter, and an ECU which calculates a value of a first control parameter, based on an output from the second air-fuel ratio sensor, and executes air-fuel ratio feedback control, based on the calculated value of the first control parameter. A value of a second control parameter to be used for calculating the value of the first control parameter is calculated based on the output from the second air-fuel ratio sensor. Whether the second air-fuel ratio sensor is deteriorated is determined based on the output from the second air-fuel ratio sensor. A value of at least one of the first and second control parameters is increased when a variation in the output from the second air-fuel ratio sensor is small during execution of the air-fuel ratio feedback control, and it is determined that the second air-fuel ratio sensor is deteriorated when the variation in the output from the second air-fuel ratio sensor is continuously small over a predetermined time period after the value of the at least one of the first and second control parameters has been increased.
