摘要： A platinum reference electrode is disposed on the surface of a blind bore formed in a body of solid zirconia electrolyte and two semi cylindrically shaped measuring electrodes one platinum the other gold are disposed on the outer surface of the body. A first annular insulator supports the body within the casing and defines two chambers on either side thereof while a second annular insulator supports and presses lead wires against the measuring electrodes. A cylindrical connector is inserted into the blind bore to provide good electrical connection between the platinum reference electrode and a lead line. Atmospheric air enters the first chamber and the blind bore while exhaust gases enter the second chamber and contact the measuring electrodes; the platinum/platinum and platinum/gold electrodes produce markedly different signals one of which is used to recalibrate the other as the peak output voltages decrease with time and temperature.

摘要： Addition air is admitted into a fuel passage of a carburetor through an open electromagnetic valve which is electronically controlled between the open and closed position in accordance with an oxygen sensor signal indicating the oxygen concentration in the engine exhaust gases. The amount of the additional air being supplied to the fuel passage is reduced at the rate proportional to the vacuum created by operation of the engine in a venturi section, choke section and/or intake manifold.

摘要： With respect to an internal combustion engine equipped with a carburetor and a catalytic converter which requires to feed the engine with a stoichiometric air/fuel mixture, the control system is for regulating the air/fuel ratio produced in the carburetor and comprises an auxiliary air admitting passage connected to the fuel discharge passage of the carburetor in addition to a usual air bleed passage for the fuel discharge passage, an electromagnetic valve for controlling the admission of air into the auxiliary passage, an oxygen sensor disposed in the exhaust system upstream of the catalytic converter, and a control circuit for producing continual pulses at a frequency between 5 and 100 Hz. The widths of the individual pulses are increased gradually while the output of the oxygen sensor indicates the air/fuel ratio being below the stoichiometric ratio, and vice versa. The valve is opened as each pulse is applied thereto so that the air feed rate to the fuel in the fuel passage is momentarily augmented by admission of air into the auxiliary passage.

摘要： A system for controlling no load operation of an internal combustion engine is provided wherein an actual engine speed signal and a target engine speed signal are compared and the air flow past a throttle valve is controlled to reduce the difference between these two signals. Subsequently, an actual air fuel ratio and a target air fuel ratio are compared and the air fuel ratio of the mixture to the engine is controlled to reduce the difference between the actual and target air fuel ratio signals. During deceleration of the engine, air flow is controlled to maintain the manifold vacuum smaller than a predetermined value so as to prevent unnecessary enrichment of the mixture due to the vacuum and then air fuel ratio is controlled to reduce the difference between the actual air fuel ratio signal and a target deceleration air fuel ratio signal.
