摘要： A method for operation of an engine fuel system includes initiating a mitigating action based on a fuel rail pressure response, the fuel rail pressure response occurring after an engine shut-down. The mitigating action includes disabling vehicle operation if fuel rail pressure drops below a threshold value after activation of one of the higher or lower pressure pumps, the activation occurring before a subsequent engine start. In this way, a distinction can be made between internal and external leaks, allowing the mitigating action taken to be adjusted accordingly.

摘要： Various systems and method for heating an engine in a vehicle are described. In one example, intake air flowing in a first direction may be heated via a gas-to-gas heat exchange with exhaust gases. The heated intake air may then be used in a subsequent gas-to-liquid heat exchange to heat a fluid circulating through the engine. In another example, intake air flowing in a second direction may be heated via a heat exchange with exhaust gases in order to cool an exhaust catalyst.

摘要： A method for combusting a vapor of a fuel accumulated in an adsorbent canister in a vehicle, the vehicle having an engine and a fuel tank coupled to the adsorbent canister. The method comprises, during a first operating condition including a higher availability of compressed air, metering the compressed air from a first air source, and flowing the metered, compressed air through the adsorbent canister along a first flow path. The method further comprises, during a second operating condition including a lower availability of compressed air, flowing air from a second air source through the adsorbent canister, and, during the first and second operating conditions, venting the fuel tank to an intake of the engine and flowing effluent enriched in the vapor from the adsorbent canister to the intake of the engine.

摘要： Methods and systems are provided for expediting engine spin-down in an engine that is shutdown during engine idle-stop conditions and restarted during restart conditions. In one example, the method comprises, during an automatic engine idle-stop, turning off spark, operating a first cylinder with a rich ratio of air to injected fuel richer than a rich flammability limit, operating a second cylinder with a lean ratio of air to injected fuel leaner than a lean flammability limit, and mixing un-combusted exhaust from the first and second cylinders with exhaust, the exhaust mixture being substantially stoichiometric.
