摘要： In the method of feedback controlling the air-fuel ratio of an internal combustion engine, the feedback control is stopped for a predetermined period of time at a specified time or condition of the engine, and the air-fuel ratio is controlled in accordance with a control signal having a value corresponding to the average value of the integrated compensation signals. In addition, a factor affecting the center value of the controlled air-fuel ratio is adjusted in accordance with the output signal of a comparator circuit generated during the time that the feedback control is being stopped.

摘要： An apparatus for controlling the atomization of fuel in an electronically fuel injection device for internal combustion engine, by jetting air or exhaust gas into the injection device so as to mix the air or the exhaust gas with the fuel thereby to atomize the fuel. The apparatus has a regulator adapted to maintain the pressure of the air or the exhaust gas at a level higher than the pressure in the main air passage by a predetermined pressure. The regulator has a housing in which a back pressure chamber and a control chamber are defined at both sides of a diaphragm accommodated by the housing. The back pressure chamber receives the air pressure transmitted from the downstream side of a throttle valve and accommodates a spring which urges the diaphragm toward the control chamber, while the control chamber receives the air from the upstream side of the throttle valve or the exhaust gas. A valve operatively connected to the diaphragm opens and closes the passage between the control chamber and the fuel injection device thereby to control and regulate the pressure of the air or the exhaust gas supplied to the fuel injection device.

摘要： In a dc electric fuel pump control apparatus for controlling the quantity of fuel supplied to a vehicle engine in accordance with an engine operating parameter condition such as an intake air flow condition or engine speed condition, when controlling a voltage applied to a fuel pump operating motor by closing or opening a fixed-resistor short-circuiting switch circuit in accordance with the magnitude of the operating parameter relative to a predetermined value, an increase or decrease of a battery power source voltage from a predetermined value is detected to increase or decrease the predetermined value of the engine operating parameter. Where a variable resistor is used in place of the fixed resistor, its resistance value in a low battery power source voltage condition is controlled lower than that in a high battery power source voltage condition.
