摘要： An air-fuel ratio detecting system detects the air-fuel ratio of the mixture supplied to an engine by means of titania whose electric resistance value varies in response to the oxygen content of the exhaust gases. The titania is connected in series with a reference resistor and a fixed voltage is applied to the junction of the titania and the reference resistor so as to generate a voltage corresponding to a change in the electric resistance of the titania. The detection voltage generated at the junction indicates the air-fuel ratio of the mixture and it is compared with a reference voltage for determining whether the air-fuel ratio is equal to the stoichiometric air-fuel ratio. The electric resistance of the titania varies with its operating temperature and the detection voltage varies correspondingly. To prevent any error in the control of air-fuel ratio due to a change in the temperature-dependent detection voltage, the peak value of the detection voltage which indicates that the air-fuel ratio of the mixture is greater than the stoichiometric ratio is sampled and the reference voltage is changed in response to the peak voltage. A programmable read-only memory is used to allow easy setting of the peak voltage and the reference voltage in a nonlinear relation with each other.

摘要： A gas component detection apparatus comprises a first and a second gas sensing elements each composed of a metal oxide which exhibits variable electric resistances according to gaseous components and temperatures of gases to be detected. A catalyst is carried at least by the first sensing element for promoting oxidation reactions of the gaseous components of the gases. A first pair of electrodes are inserted into those portions of the first sensing element which are subjected to catalytic action of the catalyst. Into the portions of the second sensing element which are not subjected to catalytic action are inserted a second pair of electrodes. The first pair of electrodes sense a variation in electric resistances resulting from the gaseous components and temperatures of the gases, while the second pair of electrodes detect an electric resistance variation related mainly upon the gas temperatures. Consequently, an output signal reflecting substantially only the gaseous components of the gases is produced by offsetting both of the electric resistances separately sensed utilizing a suitable electric circuit.

摘要： An apparatus for controlling the air-fuel ratio of an air-fuel mixture to be supplied into a combustion chamber of an internal combustion engine comprises a passage bypassing a carburetor and a throttle valve of the engine for supplying an additional air into the engine intake duct downstream of the throttle valve to dilute the air-fuel mixture to an air-fuel ratio most suited for the engine operation. An air valve is provided in the bypass passage to vary the air-flow cross-sectional area of the passage. The opening of the air valve is controlled mainly in accordance with the air-fuel ratio of the mixture as detected by an air-fuel ratio detector in the path of flow of engine exhaust gases. A variable orifice is provided in the bypass passage downstream of the air valve and defined by a valve seat and a needle valve operatively associated therewith to vary the opening area of the orifice. The needle valve is actuated by a pneumatic valve actuator which is responsive to variations in the engine manifold vacuum. The arrangement is such that the pressure difference across the air valve is kept substantially constant whereby the supply of the additional air is substantially in proportion to the engine intake air and free from influence by the engine manifold vacuum.

摘要： A gas component detection apparatus for detecting gaseous components of exhaust gases from a combustion device. There is provided a gas component detecting element composed of semiconductive metal oxides and having its outer surface partly exposed to the exhaust gases. A catalyst layer is carried on the larger part of the latter outer surface of the detecting element. A pair of electrodes are provided for sensing the electric resistance exhibited at the portion of the detecting element which carries the catalyst layer. Also another electrode is provided for cooperating with one of the above pair of electrodes to detect the electric resistance exhibited at the portion of the detecting element which does not carry the catalyst layer. The former portion of the detecting element exhibits variable electric resistances resulting from concentrations of the gaseous components and the temperatures of the exhaust gases, while the latter portion thereof exhibits variable electric resistances related mainly upon the temperatures of the exhaust gases. Consequently, an output signal reflecting substantially only the gaseous components of the exhaust gases is produced by offsetting both of the electric resistances separately sensed utilizing a suitable electric circuit.
