    摘要: In one example, a system for a vehicle traveling on the road is described. The system includes a first cylinder; a second cylinder; a linear exhaust gas sensor coupled exclusively to said first cylinder; a switching exhaust gas sensor coupled exclusively to said second cylinder; and a controller configured to operate in a first mode with both said first and second cylinders carrying out lean combustion, where fuel injection amounts to each of said first and second cylinder are adjusted based on said linear sensor; said controller further configured to operate in a second mode with both said first and second cylinders carrying out combustion about stoichiometry, where fuel injection amounts to at least one of said first and second cylinder are adjusted based on said switching sensor.

    摘要: Methods and systems are provided for operating an engine having a hydrocarbon retaining system and an emission control device coupled to an engine exhaust, the engine exhaust comprising a venturi. One example method comprises, during a storing condition, routing exhaust gas through the venturi without generating a venturi action, and then to the hydrocarbon retaining system, while bypassing the emission control device, to store hydrocarbons in the hydrocarbon retaining system, and during a purging condition, routing exhaust gas through the venturi while generating venturi action, then to the emission control device, and then to the hydrocarbon retaining system, to purge stored hydrocarbons, wherein a flow of purged hydrocarbons is drawn back to the venturi via venturi action.

    摘要: A method of removing hydrogen sulfide from an emissions stream is disclosed, wherein the method includes directing the emissions stream into a hydrogen sulfide converter having a metal oxide catalyst, adsorbing the hydrogen sulfide in the emissions stream to the metal oxide catalyst in the hydrogen sulfide converter, reacting the hydrogen sulfide with at least one of an oxidant and a reductant in the hydrogen sulfide converter to chemically transform the hydrogen sulfide, and adjusting an air-fuel ratio of the emissions stream based on exhaust temperature of an emission control device, where the adjustment varies a duration of at least one of lean and rich operation to perform the adsorbing and reacting even as exhaust temperature varies.
