摘要： A method for operating a fuel delivery system with a first pressure pump fluidly coupled to a second higher pressure pump is described. In one example, the fuel pumps are adjusted based on measured fuel pressure during a first condition. The fuel pumps are adjusted independent of the measured fuel pressure during a second condition.

摘要： A method for operating a fuel delivery system with a first pressure pump fluidly coupled to a second higher pressure pump and a fuel rail including adjusting pump operation of at least one of the first and second pumps during engine starting, the variation based on engine starting conditions. When the pressure rise during the start is correlated to an expected response, further adjusting pump operation based on measured fuel pressure, and when pressure rise during the start is less than the expected response, further adjusting pump operation independent from measured fuel pressure.

摘要： In one example, a method is described for operating an engine of a vehicle, the engine having a combustion chamber. The method may include controlling a stability of the vehicle in response to a vehicle acceleration; and adjusting dilution in the combustion chamber of the engine to reduce surge in response to the vehicle acceleration. The dilution may be adjusted by adjusting cam timing, for example.

摘要： Methods and systems are provided for reducing audible clunks and objectionable drive feel in vehicles including start/stop systems. In one example, a vehicle engine is shutdown during vehicle coasting. The vehicle engine is then restarted, while the vehicle is moving with a torque converter clutch disengaged. A transmission clutch pressure is then adjusted during the restart based on a torque converter output speed relative to a torque converter input speed.
