摘要： A method for operating a turbocharged engine is disclosed. In one example, an engine operation is adjusted in response to a turbocharger expansion ratio. Degradation of the engine may be reduced under some engine operating conditions by adjusting engine operation in response to the turbocharger expansion ratio.

摘要： Methods and systems are provided for detecting hydrocarbon ingestion into an engine based on the simultaneous monitoring of cylinder imbalance and an elevated exhaust exotherm. Crankshaft acceleration data is monitored during steady-state and transient engine conditions while exhaust temperatures are estimated during non-regeneration conditions. Engine speed and load is limited to reduce further hydrocarbon ingestion.

摘要： Methods and systems are provided for operating a fuel system in an engine, the fuel system including a supply pump for delivering fuel to the fuel system and pressurizing fuel received from a feed pump, a fuel tank, a fuel filter for filtering fuel, a fuel rail, and a fuel injector. One example method comprises, during an engine cold-start, operating the supply pump, and adjusting a supply pump operation mode between at least a pressure-controlled mode and a volume-controlled mode based on a fuel temperature and pressure.
