Title: Air fuel ratio detecting device
Inventor: MIKI MASAYUKI
IPC: G01N27/27
Filed: 1986-05-08
Abstract: PURPOSE:To prevent detection from decreasing and oscillation from being caused by simple constitution by forming a bridge circuit which includes the internal resistance of an air fuel ratio detection cell as one side and controlling the electromotive force of the cell to a specific value, controlling a heater and balancing the bridge, and detecting an air fuel ratio from the quantity of a current flowing through the resistance of one side of the bridge. CONSTITUTION:The bridge circuit which includes the internal resistance of the air fuel ratio detection cell 1 as one side is constituted by connecting the sample holding circuit composed of a switch SW2, a capacitor C1, and a differential amplifier A2 to resistances R1, R2, and r2, and an internal heater 3 is controlled by the differential amplifier A3 through a Tr so that the bridge circuit is balanced. The oxygen concentration at the exhaust-side electrode boundary surface of the cell 1, on the other hand, is so controlled that the electromotive force E of the cell 1 is constant over the entire area of an air excessive rate. For the purpose, the switch SW2 is turned off and the switch SW1 is turned on; and an integrator (R3, C2, and A1) compares the control value of electromotive force with the held value of the sample holding circuit to control the quantity of a pump current, thereby detecting an air fuel ratio from the value.

Abstract: PURPOSE:To secure compensation for the multiple reflection without imparing the signal/noise ratio and thus to ensure a constant amplification over the wide-band frequencies by giving the same circuit connection to the circuit constitution at the output side of each amplifier element as the distribution amplifier of the input side. CONSTITUTION:The constant K-type delay line is used at the input side, and the both ends of the delay line are formed into the pi-type circuits to extract the voltage between the delay lines. Characteristics impedance ZOpi of the delay line features as shown by Eq. (I), where OMEGA shows the standardized frequency. And reflection coefficient alpha becomes as shwon by Eq. (II) after the standardization of signal source impedance Zs, and the both ends of the delay line at the output side are formed into the T-type circuits. And characteristic impedance ZOT features as shown by Eq. (III) in case the voltage of the transmission end is drawn out by terminating resistance R via matching section MS. Accordingly, if terminating is given to the transmission end side with impedance Zt featuring Zt=1/Zs against impedance Zs, reflection coefficient gamma becomes as shown by Eq. (IV). In this way, the reflected waves can be eliminated completely for each delay line, thus obtaining a constant amplification over a wide band.
