摘要： An air-fuel ratio control system comprises a first oxygen concentration detector arranged upstream of a three-way catalyst for purifying the exhaust gas in the exhaust system of an internal combustion engine, a second oxygen concentration detector arranged downstream of the three-way catalyst, a discrimination circuit for detecting and discriminating a specific operating condition of the internal combustion engine in response to a signal representing operating factors of the internal combustion engine such as the amount of intake air and vehicle speed, and a change-over circuit impressed with the signals from the first and second oxygen concentration detectors. The change-over circuit produces selectively the detection signal of the second oxygen concentration detector in response to the output signal of the discrimination circuit only when the discrimination circuit detects a predetermined operating condition of the internal combustion engine, and the detection signal of the first oxygen concentration detector when the internal combustion engine is under the other operating conditions.

摘要： The air-to-fuel ratio of a combustible mixture supplied to an engine is controlled by a feedback loop which includes an integration circuit for integrating the output signal of an oxygen sensor which detects the oxygen concentration in the exhaust gases of the engine, to produce an output voltage. The output of the sensor is applied to the integration circuit through a switch which opens in response to predetermined conditions of the engine whereby the output voltage of the integration circuit is held at a value occurring just before the switch opens.

摘要： A system for controlling an oxygen concentration in exhaust gases emitted from a combustion engine. An oxygen sensor which changes a resistance in response to a sensed presence and absence of oxygen in exhaust gases is connected in series with an electric power source and a transistor to produce an output voltage indicative of the sensed presence and absence of oxygen. A comparator compares magnitudes of the sensor output voltage with a predetermined magnitude. In response to an output voltage of the comparator, the transistor controls a biasing current flowing from the electric power source to the sensor so that, when either presence or absence of oxygen is sensed, the sensor output voltage is kept substantially at the predetermined magnitude irrespective of temperature dependent changes in the resistance of the oxygen sensor.

摘要： A fuel injection pump is described wherein a plunger is rotatingly and reciprocally movable in an enclosure to define a compression chamber which is connected to a fuel inlet during an intake stroke of the plunger and to a fuel outlet during a compression stroke thereby to initiate injection of fuel to the outlet. A solenoid valve is responsive to a voltage applied from a voltage source for providing a pressure relief action on the fuel in the compression chamber. A control unit is responsive to the onset of fuel injection to determine a basic timing at which fuel is to be terminated and corrects the basic timing as a function of the source voltage to compensate for a voltage variation thereof which would otherwise affect on the operation of the solenoid valve. The solenoid valve is then energized at the corrected timing.

摘要： A closed loop air-to-fuel ratio control system having an oxygen responsive sensor and a feedback circuit is disclosed. The sensor is disposed in an engine exhaust passage to produce a voltage indicative of the oxygen concentration in the exhaust gas. This voltage is integrated in the feedback circuit to cause the mixture air-to-fuel ratio to be corrected in response thereto. The integration is controlled by the integration controller to shift the mixture air-to-fuel ratio to the one other than the stoichiometric ratio. This integration controller can be made responsive to specific engine operating conditions such as throttle valve movement.

摘要： An air-to-fuel ratio feedback control system which normally functions to correct the air-to-fuel ratio of a mixture supplied to an internal combustion engine to a predetermined air-to-fuel ratio in accordance with an output signal of an air-to-fuel ratio detector disposed in an exhaust passage. The system detects an inoperable period of the air-to-fuel ratio detector due to a low engine temperature and stops the feedback correction of the air-to-fuel ratio to prevent erroneous correction. Furthermore, during the full load operation and idling operation the system holds the feedback correction of the air-to-fuel ratio respectively at a little smaller and larger than the stoichiometric ratio irrespective of the output of the air-to-fuel ratio detector and enables to easily return to substantially the stoichiometric one when the engine operating condition returns to normal operation.

摘要： Provided is a tire air pressure monitoring system capable of sufficiently lowering the electric power dissipation in a monitoring unit. The monitoring unit acquires, on the basis of information on transmission intervals included in transmitted signals from sensor units, the next transmission timings of signals to be transmitted from the sensor units and is switched from a sleep mode to a waking-up mode to receive the transmitted signals from the sensor unit in synchronism with the next transmission timings. This can efficiently set the monitoring unit in a waking-up condition, i.e., a signal receivable condition, thereby preventing useless electric power dissipation and reducing the electric power consumption.
