摘要： The present invention is a water cut monitor which includes a settling tank in which a quantity of fluid from a producing well is accumulated. The fluid is removed as a stream of fluid after a predetermined interval from the accumulation of the fluid by the settling tank so as to allow the accumulated fluid to separate into three phases: free water, water-continuous and oil-continuous. The flow rate of the stream of fluid is measured and a corresponding flow rate signal is provided as well as a temperature signal corresponding to a sensed temperature of the stream of fluid. The water cut monitor includes a plurality of electrodes in contact with the fluid. Injection electronics connected to at least one of the electrodes provides an injection voltage and injection current to the fluid stream and also provides signals corresponding to the injection voltage and injection current. A voltage in the fluid stream is measured and a measurement signal provided. A computer determines the water cut of the petroleum stream in accordance with the temperature signal, the injection voltage and injection current signals, the electrical phase angle signal and the measured voltage signal.

摘要： Oil well production is often measured by using a settling tank, pump, flowmeter and a water-cut meter. Fluid from a well being tested is allowed to accumulate in the settling tank and, after a predetermined settling time, is pumped through the flowmeter and water-cut meter for gauging. The present invention is an improved water-cut meter which first determines the impedance of the free water pumped from the tank and later determines the impedance of the oil/water emulsion emerging from the tank. The ratio of the emulsion impedance to the free water impedance is proportional to percent water-cut of the fluid during the water-continuous phase. When the emulsion switches to oil-continuous phase, the system utilizes probe impedance for the water-cut determination. Using standard techniques, the water-cut and flow rate signals are then combined to calculate the total oil and water content of the settling tank fluid.

摘要： In a bent axis hydraulic machine, a back plate and cylinder barrel vary in distance from a drive plate as a stroke angle of the cylinder barrel changes, thereby minimizing unswept fluid volume in the cylinders of the barrel at any stroke angle. Distance is controlled by one or more rollers, engaging respective tracks that define a profile of contact that determines the distance as a function of the stroke angle. Telescoping fluid supply channels are employed to maintain a fluid supply to the cylinder barrel as the distance changes.

摘要： A variable displacement engine comprises two engine modules fed from a common fuel source, each engine module having an individual crankshaft. The first engine module has a high compression ratio (e.g., greater than 13:1), while the second module has a typical compression ratio for a gasoline engine (e.g., between 9:1 and 11:1). In one embodiment, the first engine module operates through high efficiency optimized alcohol fuel combustion when the fuel content exceeds a minimum alcohol content. In an alternative embodiment, the first engine module operates at high efficiency through gasoline HCCI combustion when conditions permit. When operating conditions do not permit the first engine module to operate at high efficiency, the second engine module operates as the primary engine module, with the first engine module available to provide supplemental power (at less than optimal efficiency) if needed to meet driver demand.

摘要： A quasi free piston engine uses, a small, lightweight crankshaft to connect the piston assemblies of the free piston engine with a flywheel. While most of the power output from the combustion pistons is extracted by pumping pistons as hydraulic power, the small crankshaft and flywheel ensure exact TDC position of the combustion pistons in operation, and provide a rotating means to drive combustion cylinder intake and exhaust valves. Flywheel speed may be monitored to provide feedback on power extraction for further control of the system. In addition, a hydraulic push-rod system for efficient valve actuation is provided.

摘要： A method is provided for close control and adjustment of in-cylinder oxygen concentration levels together with boost adjustments to minimize harmful emissions during transients in engines which utilize late direct cylinder injection of fuel. EGR flow rates are adjusted in a closed loop, linked fashion together with boost pressure changes during transients, to maintain intake charge-air oxygen concentration and boost levels within critical ranges for controlled temperature, low emission combustion. Changes in fuel feed into the cylinder are made to wait for or follow changes in the boost level of charge-air into the cylinder for combustion. Temporary fuel levels are not allowed to exceed desired fuel/oxygen ratios during transients, by controlling fuel feed responsive to the level of boost of charge-air being taken into the cylinder for combustion.

摘要： A variable displacement hydraulic/pump motor has a yoke with a pair of shafts aligned to define a yoke pivot axis and connected to a valve plate therebetween having intake and discharge apertures. A rotatable cylinder barrel has piston cylinders open at one end to receive a piston head and opening through fluid ports at another end, flush against the valve plate surface. A drive block is mounted on an input/output shaft for rotation about a central axis of rotation inclined at an angle relative to the longitudinal axis of the cylinder barrel which may be changed by a drive engaging the yoke at a point near its pivot axis. Loads on bushings supporting the yoke shafts are reduced by providing radially extending fluid ports in the shafts and in communication with the intake and discharge apertures of the valve plate.
