  • Patent number: 11365693
    Abstract: Methods and systems are provided for providing secondary air to an exhaust system during catalyst warm-up. In one example, a method may include, responsive to a cold start of an engine: operating the engine with a number of unfired cylinders and a remaining number of fired cylinders each engine cycle, and adjusting exhaust mixing by adjusting an exhaust valve parameter of at least one unfired cylinder of the number of unfired cylinders. In this way, the unfired cylinders may provide the secondary air as well as increased mixing of the secondary air with burned exhaust gas from fired cylinders, thus increasing exotherm production in the exhaust system to increase a temperature of the catalyst.

  • Patent number: 11365695
    Abstract: Methods and systems are provided for providing secondary air to an exhaust system during catalyst warm-up. In one example, a method may include, during a cold start condition, operating an engine with a number of cylinders deactivated and a remaining number of cylinders active, and adjusting a first air charge within a deactivated cylinder of the number of cylinders relative to relative to a second air charge within an active cylinder of the remaining number of cylinders. In this way, an amount of secondary air provided to the exhaust system of the engine may be more robustly controlled, thus decreasing cooling of the exhaust system during the cold start condition that may otherwise occur due to excess secondary air.

  • Patent number: 10399034
    Abstract: The high temperature titanium-catalyst comprises a body, the body having a hot gas inlet and a hot gas outlet. The body comprises an array of titanium containing catalytic elements, wherein the array of titanium containing catalytic elements is arranged such that hot gas containing an amount of hexavalent chromium Cr(VI) may enter the body at the hot gas inlet, may pass through the array of titanium containing catalytic elements and may leave the body at the hot gas outlet. When the titanium-catalyst is in use, Cr(VI) in the hot gas containing an amount of Cr(VI) reacts with titanium oxide in a surface layer of the titanium containing catalytic elements, whereby the Cr(VI) is reduced to trivalent chromium Cr(III) thus reducing the amount of Cr(VI) in the hot gas containing an amount of Cr(VI).

    Abstract: An exhaust gas purification material according to the present invention is provided with a particulate filter 10 that traps particulate matter in exhaust gas and contains an SCR catalyst for adsorbing ammonia and reducing NOx in the exhaust gas. A maximum allowable adsorption amount of ammonia adsorbable by the filter 10 differs between an upstream portion 10a of the filter 10 including an exhaust gas inlet-side end 10c, and a downstream portion 10b of the filter 10 including an exhaust gas outlet-side end 10d. The SCR catalyst contained in the upstream portion 10a and the SCR catalyst contained in the downstream portion 10b are qualitatively different. A ratio (B/A) of a maximum allowable adsorption amount of ammonia A in the upstream portion 10a and a maximum allowable adsorption amount of ammonia B in the downstream portion 10b satisfies the relationship 1.1?(B/A)?2.
