摘要： Methods and systems are provided for reducing ice formation in a charge air cooler. In one example, a method includes, operating a radiator fan of a vehicle in a first direction to cool an engine of the vehicle, and reversing a direction of rotation of the radiator fan to blow heated air towards a charge air cooler, the charge air cooler arranged proximate a radiator of the vehicle. Operating the radiator fan in a first direction may be based on the engagement of one or more gears of a transmission of the vehicle while operating the radiator fan in the reverse direction may be based on an engine temperature condition, one or more ambient weather conditions, and an engine idle condition.

摘要： Systems for efficiently starting an engine of a hybrid electric vehicle are provided. An example of a system comprises a first processor and a second processor. The second processor is configured to determine when to start an internal combustion engine, cause energy to be supplied from an energy storage device to a generator/motor to cause the generator/motor and crankshaft to rotate to at least a hold speed, transmit a first instruction to a first processor when determining that the internal combination engine should be started. The first processor does not supply fuel to at least one cylinder of the internal combustion engine in response to the first instruction. The second processor is configured to transmit a second instruction to the first processor after a variable period of time has elapse after the generator/motor or crankshaft has reached at least the hold speed.

摘要： In an aspect, a system includes a mixer configured to mix a fuel stream with a solvent to form a mixed stream, the solvent having a higher affinity for a second component of the fuel stream than for a first component of the fuel stream. The system includes a first separator configured to separate the mixed stream into (i) a first fuel fraction including the first component of the fuel stream and (ii) a mixed fraction including the second component of the fuel stream based on a difference in volatility of the first fuel fraction and the mixed fraction. The system includes a second separator configured to separate the mixed fraction into a second fuel fraction including the second component of the fuel stream and a solvent fraction.

摘要： Methods and systems are provided for detecting throttle obstructions in a vehicle. In one example, after engine start up, throttle icing condition resulting from the throttle capturing ice fragments originally formed within a charge air cooler or an intake passage upstream of throttle, may be detected. Responsive to detecting the throttle icing condition, the throttle may be adjusted to a fully open position independent of accelerator pedal position, and maintained at the fully open position for a threshold duration while maintaining a desired torque, to release the captured ice fragments from the throttle.
