| 20090139494 | DUAL PISTON DIRECT INJECTION FUEL PUMP - A fuel pump for an automotive application includes two separate pumping chambers within each of which a piston is reciprocated in order to pump fuel to an engine for the automobile. The dual cylinder arrangement increases the output capacity of the fuel pump. | 06-04-2009 |
| 20090145212 | Sensor with quick connector - A fuel injection system includes a fuel tank, a supply line, a fuel injection rail and a number of fuel injectors. The fuel tank includes a fuel tank module which houses a fuel pump. The fuel pressure within the fuel injection system is monitored by a pressure sensor which is integrated into a quick connector between the fuel supply line and the fuel tank module. | 06-11-2009 |
| 20090194075 | By-pass regulator assembly for dual ERFS/MRFS fuel pump module - A fuel system that supplies fuel to an engine of a vehicle. The fuel system includes a pump that pumps fuel and a controller that selectively changes operation of the pump between an electronic returnless fuel system mode and a mechanical returnless fuel system mode. In the electronic returnless fuel system mode, the outlet of the pump is varied, and in the mechanical returnless fuel system mode, output of the pump is maintained approximately constant. | 08-06-2009 |
| 20090235994 | COAXIAL PRESSURE RETENTION AND RELIEF MECHANISM - A pressure relief mechanism may utilize a casing that defines an internal cavity, a fluid inlet, and a fluid outlet. A first valve may reside within the internal cavity to permit fluid flow in one direction and further utilize a first valve carriage and a first valve spring that forces the first valve carriage against a first end of the casing internal cavity, over the fluid inlet. The first valve spring may reside against a second end of the casing cavity. A second valve may reside within the internal cavity and utilize a second valve carriage, a second valve body, and a second valve spring that biases the second valve body against the first valve body, the second valve permitting fluid flow opposite to the flow of the first valve. | 09-24-2009 |
| 20100174455 | FARADAY TYPE WIRELESS OXYGEN SENSOR - An oxygen sensor device and method for a motor vehicle having an electrode within an outer shell for measuring oxygen in exhaust gas exiting the vehicle. A communication device, powered by a capacitor, wirelessly transmits the measured amount of oxygen from the electrode to a powertrain control module. Vibration transmitting from the motor vehicle shakes a magnet, wound inside a coil, for generating the electrical current used by the capacitor. | 07-08-2010 |
| 20100199637 | ROTATIONAL GENERATION TYPE WIRELESS OXYGEN SENSOR - An oxygen sensor for a motor vehicle having an electrode within an outer shell measures oxygen in exhaust gas exiting the vehicle and generates a signal based on the oxygen measurement. A communication device, powered by a battery or capacitor, wirelessly transmits the measured amount of oxygen from the electrode to a powertrain control module. The flow of exhaust gas through the exhaust system spins blades to spin a generator in a rotational power generation device to generate electrical current to be stored and used by the battery or capacitor. The rotational power generation device may be located in the exhaust pipe, such as through an exhaust pipe wall, and either be connected to the oxygen sensor shell or separate and connected only with electrical wires between the generator and the battery or capacitor. | 08-12-2010 |
| 20100242597 | MULTI-JOINT FUEL LEVEL SENDER GAGE ASSEMBLY - A fuel level measuring system for a liquid fuel tank may utilize a primary sender gage assembly employing at least a primary sender gage, a primary sender arm, and a primary sender float. The system may further utilize a secondary sender gage assembly employing at least a secondary sender gage, a secondary sender arm, and a secondary sender float. A dash indicator may display a fuel level of fuel within the fuel tank based upon resistances from the sender gages. The primary sender float and the secondary sender gage are contained within a single unit that is buoyant in liquid fuel. The fuel tank may have a top dome portion and a bottom dome portion that the secondary sender float is capable of occupying while the sender gages transmit a signal corresponding to fuel levels in the tank. | 09-30-2010 |
| 20110030929 | SELF-POWERED HEAT EXCHANGER - A heat transferring apparatus may employ a heat exchanger with a fluid inlet and a fluid outlet and be coupled to a power exchange unit, which employs a driving fan fluid inlet, a series of inner fan blades to receive the fluid from the driving fan fluid inlet, and a rotable driving fan unit. The inner fan blades are attached to the rotable driving fan unit along with driving magnets. A rotatable driven fan unit has numerous outer fan blades and a series of imbedded driven magnets. The fluid drives the inner fan blades and flows into the heat exchanger. The outer fan blades force air through the heat exchanger and cools the fluid. A power transfer wall located between the inner magnets and the outer magnets transfers magnetic fields from the inner magnets to the outer magnets to impart rotation in the driven fan unit and outer fan blades. | 02-10-2011 |
| 20110146628 | RETURN FUEL DIFFUSION DEVICE AND FUEL GUIDE - A fuel pump module mounted to a fuel tank may employ a flange on a top surface of the fuel tank, a fuel inlet pipe that passes through the flange, a fuel reservoir situated near a bottom interior surface of the fuel tank, and a fuel diffuser, which may be attached to the fuel inlet pipe, that protrudes away from the flange into an interior volume of the reservoir. A fuel cylinder may surround at least part of a longitudinal length of the fuel diffuser to control passage of fuel and bubbles and may have a first end that is open and a second end that is attached to a top surface of a bottom wall of the reservoir. Alternatively, the fuel cylinder may be attached at a first end to the fuel inlet pipe and define a second end that is open such that the fuel cylinder and a reservoir bottom define a gap therebetween. | 06-23-2011 |
| 20110162624 | DIESEL START-STOP FUEL PRESSURE RESERVE DEVICE - An apparatus in a fuel path to assist in delivering fuel to an engine, the apparatus comprising: a fuel tank to contain a fuel and define a first end of the fuel path; a fuel rail to receive fuel and define a second end of the fuel path; a vacuum fuel pump to draw the liquid fuel from the fuel tank; a fuel injection pump to increase a pressure of the liquid fuel to an elevated fuel pressure before delivery of the fuel to the engine; and a check valve in the fuel path to retain fuel at the elevated fuel pressure in the fuel path. A fuel reservoir located between the vacuum fuel pump and the fuel injection pump in the fuel path, the check valve located within the fuel reservoir. The fuel injection pump is located downstream of the fuel reservoir. The fuel reservoir further comprises a fuel inlet and the check valve is located at the fuel inlet. | 07-07-2011 |
