摘要： A closed-loop emission control apparatus for internal combustion engines includes exhaust composition sensor for feedback control of the air-fuel mixture. When the temperature in the exhaust passage is lower than the operating temperature of the sensor, control is switched to an open-loop mode. The feedback control signal is fluctuated above and below a predetermined DC bias at periodic intervals during the open-loop mode to switch the control to the closed-loop mode in a minimum transition time as soon as the sensor's temperature condition warrants feedback control.

摘要： A closed-loop mixture control system for an internal combustion engine comprises a throttle position sensor and a compensator connected thereto to provide an error compensating signal in response to a throttle change. The signal is feedforwarded to adjust the air-fuel ratio to the varying engine parameters prior to the generation of control signals.

摘要： A power supply circuit arrangement for automotive vehicles comprises an engine-driven alternator, a storage battery, a battery charging circuit connected between the alternator and the battery including a diode poled in a sense to conduct current from the alternator to the battery and a plurality of connectors connected from the anode of the diode to supply current to associated load equipment. In one embodiment, a pair of series connected diodes is connected in inverse parallel relation with the charging diode for discharging the battery to supply current therefrom to the load equipments. A voltage detector is connected to the junction between the discharging diodes to generate a throttle opening signal when the voltage at the junction falls below a preset value. In another embodiment, the load equipments are divided into a first group of relatively heavy loads which can be operated on current less than the nominal value and a second group of relatively light loads which must be operated on the nominal current value, the first group being connected to the anode of the charging diode and the second group being connected to the cathode thereof.
