  • Patent number: 11965444
    Abstract: A controller for an internal combustion engine is configured to execute a determination process that determines that a deviation between a first change amount and a second change amount during a fuel cutoff operation is less than or equal to a threshold, and an anomaly diagnosing process that determines that an exhaust purification device is in a detached state when the determination process determines that the deviation is less than or equal to the threshold. The first change amount and the second change amount are change amounts per unit time of the temperature of exhaust gas on the upstream side and the downstream side of the exhaust purification device, respectively. The controller is configured to interrupt the determination process when the upstream-side temperature increases within a determination period.

  • Patent number: 11229887
    Abstract: An ozonated water supply method includes: feeding dissolving water contained in a circulation tank to an ozonation device at a given feed rate while feeding ultrapure water to the circulation tank, and returning ozonated water that has not been used at a use point to the circulation tank, dissolving ozone in the dissolving water using the ozonation device to obtain ozonated water, and feeding the ozonated water to the use point; feeding oxygen gas having a nitrogen gas content of 0.01 vol % or less to a discharge-type ozone gas-producer, and feeding the resulting ozone-containing gas to the ozonation device; adjusting the feed rate of the ultrapure water to the circulation tank; and adjusting the dissolved ozone concentration in the ozonated water. The method can reduce or suppress the accumulation of nitric acid in the recirculation system when a discharge-type ozone gas-producer is used as the ozone gas-producer.

  • Publication number: 20210053014
    Abstract: The membrane cleaning device uses treated water filtered through an MBR separation membrane as dissolution water, and performs a first process of dissolving ozone gas in the dissolution water under a neutral or alkaline condition, and a second process of dissolving ozone gas in the dissolution water under an acidic condition, to generate ozone water. At this time, whether to shift from the first process to the second process is determined on the basis of the organic substance concentration in the dissolution water, and whether to start feeding the ozone water to the separation membrane is determined on the basis of the dissolved ozone concentration in the dissolution water. Therefore, even when the organic substance concentration in the dissolution water varies depending on the MBR operation conditions, the treatment times in the first process and the second process can be optimized.

  • Patent number: 10857512
    Abstract: A diluted solution production method of the present invention is a diluted solution production method of producing a diluted solution of a second liquid by adding the second liquid a first liquid, the method including feeding the first liquid to a first pipe; and controlling pressure in a tank that stores the second liquid to add, through the second pipe that connects the tank to the first pipe, the second liquid to the first liquid in the first pipe. Adding the second liquid includes measuring a flow rate of the first liquid or the diluted solution that flows through the first pipe; measuring a component concentration of the diluted solution; and controlling the pressure in the tank, based on the measured values of the flow rate and the component concentration, so as to adjust the component concentration of the diluted solution to a specified value.

  • Publication number: 20200339444
    Abstract: An aeration amount control system includes a control device for determining a first target aeration amount as the target aeration amount, and after having determined the first target aeration amount, determining a second target aeration amount as the target aeration amount, wherein, if a first change amount of the transmembrane pressure difference of the separation membrane calculated by the measurement device for the aeration performed on the basis of the first target aeration amount by the aeration device is greater than a second change amount of the transmembrane pressure difference of the separation membrane calculated by the measurement device for the aeration performed on the basis of the second target aeration amount by the aeration device, the control device determines a value, smaller than the second target aeration amount, as a third target aeration amount.
