摘要： In an intake system comprising a first intake passage (1) having an upstream end communicating with an intake duct (3) and a downstream end communicating with an intake port of an engine cylinder, a first intake control valve (6) provided in the first intake passage, a second intake passage (2) having an upstream end communicating with the intake duct and a downstream end communicating with the intake port of the engine cylinder, a second intake control valve (7) provided in the second intake passage, an accelerator pedal(ACL) and a control unit (100) for controlling opening angles of the first and second intake control valves, the second intake control valve is opened when the first intake control valve has opened to an effective opening angle and an intake air flow rate is required to be further increased. The effective opening angle may be defined in a region where a change in the intake air flow rate of the first intake passage for a given change in the opening angle of the first intake control valve falls below a prescribed level. Thereby, as the accelerator pedal is depressed, a continuous increase in the intake air flow rate without involving a saturated region can be achieved.

摘要： Time elapsed from the time when the sensor cover is opened and power supply to the fingerprint sensor is turned from off to on is counted and when there is no fingerprint image read-in command within a specified period of time power supply to the fingerprint sensor is turned off. Even if power supply to the fingerprint sensor is turned off, when a fingerprint image read-in command executes power supply to the fingerprint sensor is turned on and read-in of a fingerprint image commences. If a fingerprint image read-in command executes when the sensor cover is closed, that command is invalidated. In such a configuration, the opening and closing of a sensor cover works in synchronicity with on/off control of power supply for a fingerprint sensor and even when the sensor cover is open, wasteful electricity consumption through power supply continuing if the fingerprint sensor is not used within a specified period of time is prevented.

摘要： A method of feedback-controlling the air-fuel ratio of a mixture supplied to an internal combustion engine to a desired air-fuel ratio which is set to a value leaner than a stoichiometric air-fuel ratio, by the use of output from an exhaust gas ingredient concentration sensor, depending upon operating conditions of the engine, the desired air-fuel ratio being set to a leaner value as the transmission of the engine is set to a smaller reduction ratio. A reduction ratio to which the transmission has been set is detected. The travelling speed of a vehicle on which the engine is installed is detected. The desired air-fuel ratio is set to a richer value as the travelling speed of the vehicle is lower, insofar as the transmission is set to the same reduction ratio.

摘要： A system for controlling an air/fuel ratio for an internal combustion engine, using an oxygen concentration sensor having a first chamber for introducing therein exhaust gas of the engine and a second chamber for introducing therein reference ambient air to detect oxygen content in the exhaust gas. In order to eliminate exhaust gas pulsation which could affect on detection accuracy, it is firstly determined if engine operation is in a transient state or in a normal state. Then the detected oxygen concentration value in the preceding cycle is added to the product obtained by multiplying the deviation between the values in the preceding and current cycles by a coefficient .alpha.. The coefficient is made different in the transient state and in the normal state. In the normal engine operation state, the coefficient .alpha. is determined from engine speed and load.

摘要： An air-fuel ratio control method for an internal combustion engine, in which the air-fuel ratio of a mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio in response to output from an exhaust gas ingredient concentration sensor. When the engine is in a predetermined decelerating condition, fuel supply to the engine is cut off. The rate of correction of the air-fuel ratio of the mixture by the feedback control is set to a larger value before a predetermined time period elapses after the engine shifted from the predetermined decelerating condition to another operating condition, than values to be set after the predetermined time period has elapsed.

摘要： A fault determining apparatus for a variable valve timing mechanism is provided for shortly and accurately determining a fault even at low oil temperatures. The mechanism is driven by an oil pressure to change a cam phase of an intake cam and/or an exhaust cam with respect to a crank shaft of an internal combustion engine, thereby controlling the actual cam phase to reach a target cam phase. The apparatus has a fault determining routine executed by an ECU (electric control unit) for determining that the mechanism is faulty when a cam phase difference between the target cam phase and the actual cam phase is not within a predetermined range, an oil temperature sensor for detecting the temperature of the working oil, and a correcting routine executed by the ECU for correcting the predetermined range in an increasing direction when the detected oil temperature is low.

摘要： An air-fuel ratio control method for an internal combustion engine. The air-fuel ratio of an air-fuel mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio dependent on operating conditions of the engine. When a transmission is being shifted or before a predetermined time period elapses after the shifting, the desired air-fuel ratio is held at a value assumed immediately before the shifting of the transmission. In another form of the invention, when the transmission is being shifted, or when the operating characteristics of at least one set of a set of intake valves and a set of exhaust valves have been not changed before the predetermined time period elapses after the shifting of the transmission, the desired air-fuel ratio is held at a value assumed before the shifting of the transmission.
