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： 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： 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.

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.

摘要： In an air-to-fuel ratio feedback control system, air-to-fuel ratio of mixture supplied to an engine is controlled to be stoichiometric in response to the oxygen concentration in exhaust gases during normal operating conditions of the engine, whereas it is controlled irrespective of the oxygen concentration during specific operating conditions such as heavy load and no load conditions of the engine. Sensor output signal indicative of the oxygen concentration which is integrated to control the air-to-fuel ratio is cut off and integrator output signal is increased or decreased by a predetermined value during the specific conditions so that the mixture is controlled to be richer or leaner as desired than the stoichiometry.

摘要： A fuel injection control system comprising an air-fuel ratio feedback control in combination with an electronically controlled fuel injection system. In this system, the concentration of oxygen contained in the engine exhaust gases is compared with a predetermined value in a comparator whereby whether the fuel injection quantity is to be corrected in a direction to increase it or in a direction to decrease it is determined in accordance with the output of the comparator, and the rate of change of the correction is controlled in accordance with a sum output produced by adding a detected value of engine rpms and a detected value of engine intake state. When the air-fuel control cannot operate properly, for example because of a low exhaust temperature or under deceleration conditions, a holding circuit is connected to the integrater output to maintain the integrated output at a value intermediate the fluctuating range thereof. The system has an excellent follow-up characteristic to respond to rapid changes in the operating conditions of an engine and it is capable of maintaining the air-fuel mixture ratio at a predetermined value.
