摘要： An air-fuel ratio control system for an internal combustion engine includes an air-fuel ratio sensor provided at a collecting portion of an exhaust manifold. The air-fuel ratio sensor monitors an exhaust gas and changes its output in a linear fashion relative to an air-fuel ratio represented by the exhaust gas. The air-fuel ratio sensor is arranged at a position such that, after the number of strokes, corresponding to a multiple of the number of all cylinders, from a fuel injection for each cylinder, the air-fuel ratio sensor can measure an air-fuel ratio caused by the corresponding fuel injection. The system stores a target fuel amount for each of the cylinders. The system derives a feedback correction value depending on a deviation between a fuel amount introduced into the corresponding cylinder, which is derived based on the air-fuel ratio monitored by the air-fuel ratio sensor, and the stored number-of-stroke prior target fuel amount.

摘要： An air-fuel ratio control apparatus of an internal combustion engine capable of learning and controlling an air-fuel ratio accurately both in idling and non-idling without being affected by concentration of evaporated fuel. Uniform deviation of an air-fuel ratio is detected before starting purging of the evaporated fuel (steps S133 to S137), air-fuel ratio learning values KGI.sub.0 to KGI.sub.7 and KGS.sub.0 to KGS.sub.7 are stored respectively so that the uniform deviation shows a predetermined value or lower both at idling time and at non-idling time (steps S138 to S142), and air-fuel learning values KG.sub.0 to KG.sub.7 in respective areas including idling are updated or renewed with a value obtained by leveling or averaging air-fuel ratio learning values KGI.sub.0 to KGI.sub.7 and KGS.sub.0 to KGS.sub.7 stored both at idling time and at non-idling time (step S145). Thereafter, purging of the evaporated fuel is started, and area learning of the air-fuel ratio is also executed by air-fuel ratio learning values KG.sub.0 to KG.sub.7 in respective areas.

摘要： A detecting system for condition of a fuel evaporative emission generated in a fuel tank, includes a pressure sensor and a three-way valve for selectively connecting the pressure sensor to atmosphere and the fuel tank. The pressure sensor is initially communicated with the atmosphere to detect an atmospheric pressure P.sub.a (step 110), and subsequently communicated with the fuel tank to detect an internal pressure P.sub.f of the fuel tank (step 130). Based on the atmospheric pressure P.sub.a and the internal pressure P.sub.f of the fuel tank, an amount EVP of the fuel evaporative emission generated in the fuel tank is derived through a map look-up against a preset map (step 150).

摘要： The ignition timing is sustained at an initial value during a predetermined time beginning at a start of an engine, and is retarded after the predetermined time is elapsed to heat a catalyst at an early time. The predetermined time ends when the negative pressure of an intake pipe or the negative pressure of a brake booster reaches to a predetermined value. That is, the predetermined time is a period, which begins at a start of the engine and ends when a proper negative pressure can be sustained in the brake booster. As a result, it is possible to assure a negative pressure in the brake booster at an early time and to reduce exhaust emission at a start of the engine simultaneously.

摘要： A control duty is obtained, which asymptotically makes the output of a control subject consistent with an output of a reference model. The output of the control subject simulates a dynamic characteristic of a variable valve timing controller, and the output of the reference model simulates an ideal input-output characteristic of the variable valve timing. The control duty makes a difference between the output of the reference model and an actual valve timing small enough. A parameter of a controller is consecutively corrected to make the difference small by means of a parameter correcting mechanism when the dynamic characteristic of the variable valve timing controller is varied due to a variation of an operating environment thereof so that the difference becomes large.

摘要： A required valve timing change rate Vreq is calculated so as to make a deviation D between a target valve timing VTtg and an actual valve timing VT small and then a required speed difference DMCRreq between a motor 26 and a camshaft 16 is calculated on a basis of the required valve timing change rate Vreq. When the deviation D is larger than a predetermined value, a required motor speed Rmreq is calculated by adding the required speed difference DMCRreq to a camshaft speed RC and a motor control value is calculated so as to control the motor speed RM to the required motor speed Rmreq. When the deviation D is not larger than the predetermined value, the camshaft speed RC is set as the required motor speed Rmreq and the motor control value is calculated so as to control the motor speed RM to the camshaft speed RC.
