Patent number: 10428648Abstract: A downhole formation fluid viscometer sensor and method therefor include a viscometer sensing package, a flexible diaphragm, a magnet and electric coil, and a signal pickup assembly. The viscometer sensor may also include a first cavity and a second cavity for mechanical and electric energy transfer. The magnet and electric coil may be driven by external alternating current to generate an electromagnetic force. Silicon oil may be used to fill the first cavity and/or a pressure balance hole may connect the first cavity to an external area. The diaphragm may be a titanium alloy and a ferromagnetic magnet may be attached to the diaphragm. The diaphragm preferably has a thickness from about 0.030 to about 0.040 inches and the magnet and electric coil can propel the diaphragm to vibrate at a frequency from 0 to 100 kHz. Formation fluid viscosity is determined using resonant frequency linewidth, with contributions from the sensor package intrinsic properties removed.Type: GrantFiled: September 16, 2014Date of Patent: October 1, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Hua Xia, Lizheng Zhang, Robert Atkinson, Nestor Rodriguez, Christopher Michael Jones, Darren Gascooke

Patent number: 9874506Abstract: System, methods, and apparatuses for determining properties of a production fluid downhole are presented. In one instance, a system includes a sample-filled sensing device for vibrating a first suspended tube containing a sample of production fluid and producing a first response signal. The system also includes a reference-fluid sensing device with a second suspended tube containing a viscosity-tunable fluid therein. The system vibrates the second suspended tube to create a second response signal. The viscosity of the viscosity-tunable fluid is varied until it is deemed to match that of the sample production fluid. Other systems and methods are presented.Type: GrantFiled: November 6, 2013Date of Patent: January 23, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Li Gao, Michael T.

Patent number: 9328707Abstract: The invention relates to a control chamber, the pressure of which determines the strokes or positions of a nozzle needle, and which is assigned to a force or pressure sensor in order to detect the progression of the control chamber pressure. Because the control chamber pressure significantly changes during the closing of the nozzle needle, the operating phases of the injector can be exactly determined from the sensor data and supplied to an engine controller.Type: GrantFiled: December 3, 2010Date of Patent: May 3, 2016Assignee: Robert Bosch GmbHInventors: Nestor Rodriguez-Amaya, Siegfried Ruthardt, Holger Rapp, Wolfgang Stoecklein, Bernd Berghaenel, Marco Beier

Patent number: 9206779Abstract: The invention relates to an injection device, in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve unit which comprises a valve needle, an injection chamber having at least one injection opening, and a control chamber, wherein the injection device is designed so that a pressure differential between the injection chamber and the control chamber brings about a displacement of the valve needle between an open position in which the valve needle releases a fluid flow through the injection opening, and a closed position in which the valve needle closes off the injection opening. The injection device also has a pump unit integrated in the injection device. The pump unit is designed so as to draw in fluid from the fluid inlet during operation and to provide said fluid to the valve unit under increased pressure.Type: GrantFiled: July 18, 2011Date of Patent: December 8, 2015Assignee: Robert Bosch GmbHInventors: Nestor Rodriguez-Amaya, Jochen Doehring, Juergen Hanneke, Godehard Nentwig

Patent number: 9206758Abstract: A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.Type: GrantFiled: November 23, 2011Date of Patent: December 8, 2015Assignee: ROBERT BOSCH GMBHInventors: Nestor Rodriguez-Amaya, Siegfried Ruthardt, Holger Rapp, Wolfgang Stoecklein, Bernd Berghaenel, Marco Beier
