    摘要: A method is described for operating an engine and an emission control system downstream of the engine, the emission control system including a catalyst, an exhaust gas path coupling the engine to the catalyst, a first air-fuel ratio sensor positioned upstream of the catalyst and a second air-fuel ratio sensor positioned adjacent to or downstream of the catalyst. The method includes correlating variation in the catalyst performance across air-fuel ratios, as identified via the first and second sensors, to fuel composition of fuel combusted in the engine.

    摘要: A method for controlling an internal combustion engine wherein, during an initial, relatively low temperature operating phase of the engine, the engine operates with a modulated air/fuel ratio established independently of the operating condition of the engine and wherein, during a subsequent higher temperature operating phase of the engine, the air/fuel ratio is modulated in as a function of the operating conditions of the engine.

    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: Methods and systems for selectively fuelling a vehicle are provided. One example method of fuelling a vehicle may include receiving a fuel in a fuel reservoir in the vehicle, and directing the fuel to one of a plurality of storage tanks based on a fuel type. In one example, the directing of fuel may include adjusting one or more fuelling valves positioned between the fuel reservoir and the plurality of storage tanks to vary a direction of fuel flow to the plurality of storage tanks.
