  • Patent number: 10342885
    Abstract: The present invention relates to a vehicular air cleaner. It is an object to provide a DOR system which can utilize a purifying function of an ozone purifying element containing an activated carbon for a long period of time. As shown in A1 and A2 of FIG. 5, in the activated carbon at an initial state, an ozone purification rate is almost the same as the same wind velocity even when a temperature condition is different, even though the ozone purification rate is changed when the wind velocity is changed. After the endurance test, the ozone purification rate is increased even at the same wind velocity when the temperature becomes high as shown in B1 and B2 of FIG. 5. Thus, the temperature condition difference affects the ozone purification rate more as the deterioration o the activated carbon continues.

  • Patent number: 10222426
    Abstract: A method for dynamic characterization of an electrochemical system (such as a lithium-ion battery) is provided, comprising exciting an electrochemical system with a plurality of double-pulse sequences, each comprising a constant-current discharge pulse, a constant-current charge pulse having the same pulse width and pulse amplitude, and a zero-current period between the pulses; and calculating an impulse response, using a recursive or matrix-based method, to dynamically characterize the electrochemical system. A constant state-of-charge is maintained in the electrochemical system. Therefore the signal-to-noise ratio is high due to the repetition of the driving sequence. This method may be employed for on-line determination of the impedance spectrum of an electrochemical system, since the cycling profile can be easily integrated into charge/discharge profiles. Batteries (and other devices) can be diagnosed at high speed and with high accuracy. The double-pulse sequence is robust for fairly noisy systems.

  • Patent number: 10119448
    Abstract: Embodiments of the present disclosure may improve the accuracy of diagnosis in diagnosing whether an exhaust gas purification system having an SCR filter is faulty. It is determined that the exhaust gas purification system is faulty if the NOx removal rate with the SCR filter calculated using a measurement value of an NOx sensor is lower than or equal to a predetermined criterion removal rate. In the apparatus, a differential pressure change rate defined as the increase in a converted differential pressure value per unit increase in the filter PM deposition amount is calculated. The value of the criterion removal rate is set higher when the differential pressure change rate at the time when the measurement value of the NOx sensor is obtained is lower than a predetermined threshold than when the differential pressure change rate is higher than or equal to the predetermined threshold.

  • Publication number: 20150017060
    Abstract: A process and apparatus for disinfection of spaces using a disinfecting liquid droplet spray atomization are described, in which an electric fan 107 is used to dispense the atomization from an atomization chamber 104 via venture outlets 106 into the space to be disinfected. The operation of the electric fan 107 is modulated in a substantially random sequence to vary the rate of dispensing into the space in order to improve the dispersal of the atomized droplets in the space and hence the efficacy of disinfection.

  • Publication number: 20150010449
    Abstract: A catalyst system may include a three-way catalyst that receives exhaust gases from an engine and an ammonia slip catalyst that receives exhaust gases from the three-way catalyst. An air injection component can be configured between the three-way catalyst and the ammonia slip catalyst. A first sensor can determine first exhaust gases data and transmits that data to a controller, while a second sensor can determine second exhaust gases data and transmit that data to a controller. The controller can estimate unmeasured exhaust gases data based on the data received from the sensors and determine a setting of a component of the system and/or of the engine based on the unmeasured exhaust gases data.

  • Patent number: 8920732
    Abstract: The present disclosure is directed to systems and methods for actively controlling the steam-to-carbon ratio in hydrogen-producing fuel processing systems that include a feedstock delivery system. The feedstock delivery system supplies a combined feedstock stream including steam and carbon-containing feedstock to a hydrogen-producing region, which produces a mixed gas stream including hydrogen gas as a majority component therefrom. The systems and methods may include measuring a thermodynamic property of a steam stream, a carbon-containing feedstock stream, and/or the combined feedstock stream and controlling the flow rate and/or pressure of a water stream, the steam stream, and/or the carbon-containing feedstock stream based on a desired steam-to-carbon ratio in the combined feedstock stream and/or a desired flow rate of the mixed gas stream and may include feedforward and/or feedback control strategies.

    Abstract: Reductant dosing systems and methods for engine exhaust aftertreatment are disclosed. The opening and closing of a metering valve in the reductant dosing system is controlled in a manner that mitigates pressure oscillations in the dosing system. The metering valve is opened in response to the dosing command exceeding a minimum threshold value and the differential pressure across the metering valve exceeding a differential pressure threshold. The metering valve is closed in response to either the differential pressure across the metering valve dropping below a differential pressure threshold or the actual dosed quantity exceeding the dosing command.
