Patent number: 9556805Abstract: An improved fuel system for a dual-fuel internal combustion engine. During normal operation, the primary fuel passes through a pressure regulator before arriving at a primary fuel rail. Further, pressurized secondary fuel is delivered to both a secondary fuel rail and to the pressure regulator for purposes of regulating the output pressure of the primary fuel that is delivered to the primary fuel rail. When the pressure at the primary fuel supply or between the primary fuel supply and the pressure regulator drops below a minimum operating pressure, the pressure regulator is isolated from the secondary fuel and the secondary fuel continues to be pressurized until it reaches a suitable pressure for operating in a limp mode. Then, the secondary fuel, which is pressurized to greater than a normal operating pressure, may be injected at the higher pressure for improved performance of the engine in the limp mode.Type: GrantFiled: February 18, 2015Date of Patent: January 31, 2017Assignee: Caterpillar Inc.Inventors: David Kalu Mumford, Josh Steffen, Derek Puzzuoli

Patent number: 9556845Abstract: Methods and systems for utilizing heated fuel to compensate for a low cetane number, cetane number variance and sub-optimal engine cold-start performance in internal combustion engines are disclosed herein. Systems comprise a heater, a sensor, and an engine control unit (“ECU”). Methods can comprise detecting variables that affect combustion, calculating conditions inside a combustion chamber, determining the difference between current ignition delay and a desired ignition delay, estimating a cetane number of a fuel, and using the data to determine a suitable temperature that will compensate for cetane number and improve the ignition delay. Other methods comprise sending a signal to a heater in communication with a fuel injection system such that said heater warms fuel within the fuel injection system prior to injecting the fuel into a combustion chamber.Type: GrantFiled: March 12, 2014Date of Patent: January 31, 2017Assignee: EcoMotors, Inc.Inventor: Shizuo Sasaki

Patent number: 9556846Abstract: An engine ignition shutdown module includes a voltage regulator circuit connected to a key switch, and a pair of isolated MOSFET driver circuits connected to the voltage regulator circuit. Each MOSFET driver circuit charges a capacitor while the key switch is in a run position and the interlock switches are closed, and each capacitor discharges through a resistor for a time delay period once the key switch is moved from the run position to an off position or at least one of the interlock switches are opened. A pair of high voltage output MOSFET transistors are switched on while the capacitors discharge and provide an output to a magneto ignition for the time delay period.Type: GrantFiled: March 11, 2013Date of Patent: January 31, 2017Assignee: DEERE & COMPANYInventors: David A. Straka, Quintin D. Rigert, Jason D. Raabe, Allan D. Narveson

Patent number: 9556847Abstract: A plasma ignition device 20 includes a spark plug 100, a DC power supply 210, an AC power supply 220, and a coupling section 300. The coupling section 300 includes a capacitor 320 which electrically connects the AC power supply 220 to the spark plug 100. The coupling section 300 reduces the capacitance of the capacitor 320 in the second ignition mode in which transmission of AC power is halted, as compared with that in the first ignition mode in which AC power is transmitted to the spark plug 100.Type: GrantFiled: September 1, 2011Date of Patent: January 31, 2017Assignee: NGK SPARK PLUG CO., LTD.Inventors: Tatsunori Yamada, Kohei Katsuraya

Patent number: 9556849Abstract: A rotor blade assembly for a wind turbine includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge. A vortex generator accessory is mounted to either of the suction side or pressure side and includes a base portion and a protrusion member extending upwardly from the base portion. An attachment layer connects the base portion to the suction or pressure side. The attachment layer has a lower shear modulus than the base portion to allow for shear slippage between the base portion and the underlying suction or pressure side.Type: GrantFiled: May 2, 2013Date of Patent: January 31, 2017Assignee: General Electric CompanyInventors: Scott Gabell Riddell, Michael Christopher Booth, James Robert Tobin

Patent number: 9556852Abstract: This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power (both active and reactive) is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment based on correction factors relating to the operating conditions of the wind park. This method may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant.Type: GrantFiled: September 3, 2013Date of Patent: January 31, 2017Assignee: VESTAS WIND SYSTEMS A/SInventors: Mehrdad Babazadeh, Saed Ehsani, Martin Ansbjerg Kjær, Henrik B.
