摘要： A secondary air intake system for adding air to the intake of an internal combustion engine includes an air control valve for changing the open area of a secondary air intake passage. The air control valve is opened and closed from a first and second pressure supply means. A first pressure supply means gradually supplies the first and second control pressure to operate the air control valve and open and close the secondary air intake passage in response to an air-fuel ratio signal. The first pressure supply means also supplies the second control pressure independent of the air-fuel ratio signal during a predetermined engine operating state. A second pressure supply means supplies the second control pressure separately of the first pressure supply means during a predetermined engine operating state.

摘要： An air-fuel ratio control system for an internal combustion engine mounted on a vehicle with a transmission, including an oxygen concentration sensor producing an output signal whose level is substantially proportional to an oxygen concentration of the exhaust gas, effects a feedback control of the air-fuel ratio of mixture to be supplied to the engine toward a target value determined on the basis of various parameters of the engine operation and corrected in response to a magnitude of atmospheric pressure, so that the higher a shift position of the transmission gear is, the leaner the target air-fuel ratio becomes. Thus, the fuel consumption in a light load operating condition of the engine is decreased and the driveability of the vehicle is improved.

摘要： A method for directing an up shift operation for a vehicle having an engine and a manual transmission generates a direction of an up-shift operation when the vehicle speed exceeds a reference speed determined for each gear position. The reference speed of a medium speed gear is varied according to the degree of acceleration at the time of the previous up-shift operation. If the up-shift operation from a low speed gear to the medium speed gear is effected while the vehicle is not accelerating rapidly, the reference speed for an up shift operation from the medium speed gear is lowered. Further, if a cruising state of the vehicle with the medium speed gear after the acceleration is continued for more than a predetermined time period, the reference speed for an up-shift operation from the medium speed gear is also lowered.

摘要： An apparatus for sensing the concentration of oxygen in a gas such as engine exhaust gas includes an oxygen concentration sensor formed of an oxygen pump element and a sensor cell element, each based on a solid electrolytic member formed of a material such as ZrO.sub.2, and is provided with a limiter circuit which functions to reduce the level of current supplied to the oxygen pump element when a voltage produced by the sensor cell element indicates that this current level is such as to produce a "blackening" phenomenon whereby deterioration of the oxygen pump element will occur and oxygen concentration sensing reliability will be lowered. The apparatus also includes a delay circuit which functions such that a reduction of the oxygen pump element current level is delayed by a predetermined time interval, after an increase of the sensor cell element voltage to the "blanking" region is detected, thereby preventing fluctuations in the oxygen pump element current level due to transient increases in sensor cell element voltage and increasing the sensing reliability.
