  • Publication number: 20190120107
    Abstract: An exhaust purification system comprises a catalyst 20, an upstream side air-fuel ratio sensor 40, a downstream side air-fuel ratio sensor 41, and an air-fuel ratio control device. The air-fuel ratio control device alternately switches a target air-fuel ratio between a rich set air-fuel ratio and a lean set air-fuel ratio, calculates an oxygen storage amount and an oxygen discharge amount, updates a learning value, and corrects an air-fuel ratio-related parameter based on the learning value. The air-fuel ratio control device changes a condition for switching the target air-fuel, stores the learning value at the time when the operating state of the internal combustion engine changes from the first state to the second state as a first state value, and updates the learning value to the first state value when the operating state of the internal combustion engine returns from the second state to the first state.

  • Patent number: 10265645
    Abstract: Provided is a method for producing an electrode paste capable of readily and reliably removing bubbles from the produced electrode paste. A method includes a step for performing vacuum-defoaming of bubbles present in an electrode paste (8) by vacuuming the inside of a defoaming tank (6) while introducing the electrode paste (8) to the defoaming tank (6). In the step for performing vacuum-defoaming of bubbles present in an electrode paste (8), a rising velocity (fluid surface rising velocity VL) of the fluid surface of the electrode paste (8) in the defoaming tank (6) is made smaller than a rising velocity (reference bubble rising velocity VGa) of the bubbles in the electrode paste (8) by adjusting a flow rate (supply flow rate Q) of the electrode paste (8) introduced to the defoaming tank (6).

  • Patent number: 10268785
    Abstract: A CPU uses a simulation in which a vehicle model is made to run to calculate the amplitude of pressure variations generated on the surface of the vehicle model for each location on the vehicle model surface, and to calculate a mean surface flow velocity, which is a time average at a predetermined time of the flow rate of a fluid on the vehicle model surface, for each position on the surface of the vehicle model. The CPU also calculates an acoustic intensity for the respective locations on the vehicle model surface based on the calculated amplitude of the pressure variations and on the calculated mean surface flow velocity, and, by performing surface integration on the calculated acoustic intensities on the vehicle model surface, also calculates an acoustic power, which is the total energy of the sound emitted from the vehicle model surface.

    Abstract: An exhaust purification system of an internal combustion engine comprising an exhaust treatment catalyst (13) arranged in an engine exhaust passage and a heat and hydrogen generation device (50) able to feed only heat or heat and hydrogen to the exhaust treatment catalyst (13). When the warm-up operation of the heat and hydrogen generation device (50) is completed and a reforming action by a reformer catalyst (54) becomes possible, if the temperature of the exhaust treatment catalyst (13) is a preset activation temperature or more, a partial oxidation reaction is performed at the heat and hydrogen generation device (50) and the generated heat and hydrogen are fed to the exhaust treatment catalyst (50). At this time, if the temperature of the exhaust treatment catalyst (13) is less than the preset activation temperature, a complete oxidation reaction by a lean air-fuel ratio is continued and a heat is fed to the exhaust treatment catalyst (13).
