    摘要: Disclosed in the present invention are a pressure equalizing system for air separation purification, and a control method. The system comprises: a first air main pipe; a pressurizing gas pipeline, which is connected to the first air main pipe and used for receiving a pressurizing gas and delivering same to the first air main pipe; and a control valve, located on the pressurizing gas pipeline, and having a degree of opening regulated by the flow regulator, thereby regulating an air intake amount of the pressurizing gas pipeline. The present invention solves the problem of an air separation rectification process being affected when dry nitrogen is used for pressure equalization of an adsorber; in the switching process of entering an adsorption stage from a regeneration stage, pressurizing dry nitrogen used in a pressure equalizing step previously mixes with damp air from a main air compressor before entering the adsorber, such that the gas components flowing towards an air separation cold box remain substantially unchanged, in order to reduce disturbance in conditions of gas entering a rectification column to take part in rectification due to a gas component gradually changing from dry nitrogen to dry air in the prior art, thus stabilizing the process conditions of the air separation cold box.

    摘要: The present disclosure provides an overhead console for a motor vehicle that can firmly hold, store and allow viewing of a portable electronic device. The overhead console can include a sunglass storage bin that is pivotally attached to an overhead console storage structure, the sunglass storage bin having a closed position and an open position. The console can also include a storage unit insert that is attached to and located at least partially within the sunglass storage bin. The storage unit insert can be dimensioned to hold a portable electronic device within the sunglass storage bin and allow the device to be stored out of view when the sunglass storage bin is in the closed position and allow viewing of the electronic device when the sunglass storage bin is in the open position.

    摘要: Information relating to relative fuel pump camshaft advance angle is compared with a SOC signal indicative of the start of combustion in a reference cylinder to generate an adaptive trim table which is used, in a first control scheme to calculate an actual combustion angle for closed loop control over combustion timing only in the event of a loss of the SOC signal. In an alternate control scheme, the values from the adaptive trim table are always used to calculate the actual combustion angle for closed loop control.
