20090107470 | Electronic fuel pump - A fuel pump for deployment in a fuel system for an internal combustion engine comprises a 3-phase brushless direct current motor, a sling vane impeller with blade-shaped sling vanes, sensorless electronic motor drive and an electronic controller. The controller is adapted to receive analog or pulse-width modulation inputs to control pump speed. | 04-30-2009 |
20100036584 | Return-flow electronic fuel pressure regulator - A return-flow electronic fuel pressure regulator for a fuel-injected engine fuel system is plumbed to the fuel rail and return line of the fuel system. The regulator includes a fill chamber connected to the fuel rail, a return chamber connected to the return line and a return reservoir disposed between the fill chamber and return chamber. Fuel flow from the fill chamber to the return reservoir is regulated via a diaphragm valve assembly. Fuel flow from the return reservoir to the return chamber is subject to restriction by an adjustable valve. Integral comparative pressure sensing means measures the fuel pressure drop between the return reservoir and return chamber. An electronic control module, preferably programmed to maintain a constant pressure drop between the return reservoir and return chamber, receives a signal from the pressure sensing means and outputs a power supply signal to the fuel pump to control pump speed. | 02-11-2010 |
20100036585 | Programmable fuel pump control - A programmable fuel pump control for a fuel system includes integral sensors, an expansible fill chamber and a return chamber. The control can be used in either a return-style of returnless fuel system. The expansible fill chamber is in fluid communication with the fuel rail. A restrictable fuel passage connects the fill chamber to a return chamber that in a return-style fuel system can be optionally connected to a return line. The control includes an integral pressure transducer measuring fuel pressure relative to intake manifold pressure and one or more adjunct sensors that allow real time control of a fuel pump speed, and therefore fuel pressure, as a function of engine performance. | 02-11-2010 |
