摘要： A fuel pump is provided having improved efficiency by lowering the wet circle index of the pump while maintaining robust axial clearances to meet the demands of an automotive application. One embodiment includes a fuel pump for pressurizing fuel for delivery to an engine of a motor vehicle. The fuel pump generally comprises a housing, a motor, a single sided impeller, a cover and a body. The provision of a single sided impeller greatly reduces the wet circle index and improves the pump efficiency. The cover, impeller, and body are structured to axially balance the impeller which is free floating on the shaft of the motor.

摘要： A rotary fuel pump employs pressure balancing features on the non-vaned side of the impeller to provide localized application of fluid forces so that the impeller is more precisely balanced within the pumping chamber. A generally disc-shaped impeller body has an impeller with a body-side surface and a cover-side surface. The cover-side surface defines an impeller flow channel extending circumferentially around the impeller. The impeller includes a plurality of vanes positioned at least partially within the impeller flow channel. The body-side surface has a plurality of discontinuous undercut regions each coaxially aligned with at least a portion of the impeller flow channel. The impeller has a plurality of apertures wherein each aperture connects the impeller flow channel with a respective undercut region, whereby pressure forces against the impeller from the fuel are substantially balanced in the axial direction.

摘要： An in-tank fuel supply unit self cleans the mesh filter of the primary fuel pump, thereby permitting smaller mesh sizes to decrease pump wear and increase the life of the pump. Generally, the in-tank fuel supply unit includes a reservoir, an auxiliary fuel pump, a primary fuel pump and a filter. Fuel exiting the auxiliary fuel pump outlet is directed towards the filter to wash debris from the filter. Preferably a swirling flow is generated within the reservoir, or the system in run in an overflow condition to assist in the self cleaning of the fuel filter.

摘要： A diagnostic system and method for an electric power steering system are provided. The diagnostic system includes a first microprocessor that determines a first relative position value indicating the relative rotational position of the rotatable shaft at the first time based on the signals from first and second position sensors. A second microprocessor determines a second relative position value indicating the relative rotational position of the rotatable shaft at the first time based on the signals from third and fourth position sensors. The first microprocessor determines whether the first relative position value is an acceptable value based on a difference between the first relative position value and the second relative position value.

An electrode for an electrochemical cell comprises an electrochemically active material comprising non-crystalline silicon and crystalline silicon, where the non-crystalline silicon and the crystalline silicon are present prior to cycling of the electrode. A method of controlling the crystallinity of a silicon powder includes heating a reactor to a temperature of no more than 650° C. and flowing a feed gas comprising silane and a carrier gas into the reactor while maintaining an internal reactor pressure of about 2 atm or less. The silane decomposes to form a silicon powder having a controlled crystallinity and comprising non-crystalline silicon.
