20100219360 | Directly Actuated Valve With A Strain-Type Actuator And A Method Of Operating Same - A method is provided for operating a directly actuated valve that comprises a strain-type actuator to actuate a valve member to travel between a closed position and an open position, the method comprising transmitting displacements from the strain-type actuator to the valve member, maintaining a compressive stress on the actuator that is greater than a predetermined minimum stress by applying a pre-load compressive stress and limiting to less than predetermined limits at least one of: (a) acceleration and deceleration of the valve member when moving between open positions and the closed position; and (b) velocity of said valve member immediately before contacting the valve seat. | 09-02-2010 |
20100286891 | Method And Apparatus For Using An Accelerometer Signal To Detect Misfiring In An Internal Combustion Engine - The method comprises operating an engine and collecting a real-time accelerometer signal from an accelerometer sensor. The real-time accelerometer signal is digitized and filtered to isolate data in a frequency range associated with combustion to produce a filtered signal data set. The filtered signal data set is integrated to produce an integrated signal data set, and misfire is detected by comparing the integrated signal data set with a predetermined reference data set associated with the same operating point. The apparatus is a control system for an engine that comprises an accelerometer sensor mounted to the engine; a look-up table in which is stored predetermined reference data sets, in association with predetermined operating conditions; and an electronic controller programmed to carry out the foregoing method. | 11-11-2010 |
20110108631 | Fuel Injection Valve And Method For Co-Injecting A Liquid And A Gaseous Fuel Into The Combustion Chamber Of An Internal Combustion Engine - A fuel injection valve co-injects a liquid and a gaseous fuel into the combustion chamber of an internal combustion engine. A solid needle regulates the injection of liquid and gaseous fuels from a cavity in the fuel injection valve into the combustion chamber when the needle is lifted to its open position. In preferred embodiments, liquid fuel is metered and pressurized in an intensifier's cylinder provided within the valve body and the liquid fuel is delivered through a restricted flow passage into the cavity where it mixes with the gaseous fuel. The restricted flow passage can be formed by a small passage formed in the valve body or an annular passage between the needle and the valve body. | 05-12-2011 |

20140238351 | Method And Apparatus For Pumping Fuel To A Fuel Injection System - A method and apparatus pump fuel to a fuel injection system in an internal combustion engine. The method comprises steps of pumping a liquid fuel to a first pressure, using the liquid fuel at the first pressure as a hydraulic fluid for driving a gaseous fuel pump, and pumping a gaseous fuel to a second pressure with the gaseous fuel pump. | 08-28-2014 |
20150083055 | Supplying Gaseous Fuel from a Liquid State to an Internal Combustion Engine - An improved apparatus supplies gaseous fuel from a liquid state to an internal combustion engine comprising an electrical energy generating apparatus for generating electrical energy from a store of chemical energy. A liquid pumping apparatus for pumping the gaseous fuel in the liquid state includes an energy converter for converting the electrical energy to mechanical energy which drives the liquid pumping apparatus. The liquid pumping apparatus also includes a first heat exchanger for vaporizing the gaseous fuel received from the pumping apparatus and a controller programmed to operate the liquid pumping apparatus to maintain a pressure of the gaseous fuel supplied to the internal combustion engine within a predetermined range. | 03-26-2015 |
