摘要: A test apparatus and method is disclosed for a fuel pump mounted on and driven by an engine, the speed of which is controlled by the pressure of fuel supplied thereto wherein the engine continues to be supplied with fuel from the fuel pump during the test. A fluid circuit is provided which is designed to supply fuel to the engine under controlled pressure to permit the engine speed to be controlled independently of the engine throttle position and to permit the flow rate of the fuel to be adjusted to a predetermined value at which the output pressure of the fuel pump may be measured for calibration purposes. The fluid circuitry and necessary measurement circuitry may be mounted within a small, portable housing to allow for field testing of a fuel pump.

摘要: This disclosure relates to detection of air in the fuel supply system of an internal combustion engine of the character wherein the fuel rate supplied to the engine is controlled by regulating the feed pressure to a set of fuel injectors. A pressure sensor is connected in the fuel supply system and an engine speed sensor is connected to the engine. The engine is started, brought to a stable intermediate no-load speed, the throttle is snapped to a wide open position, and the rate of change of fuel pressure with time is sensed during the initial pressure rise from no load pressure to full load pressure. This measured rate is compared with a reference rate obtained from an engine where no air is present in the fuel system, and the pressure of air is indicated by a comparison of the measured and reference rates.

摘要: This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine. Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are fed to computer processing equipment. Two of the parameters are the lubricant system pressure and the engine speed. To test the lubricant system, the engine speed is stabilized at maximum governed speed and then the fuel supply to the engine is quickly cut off. The lubricant system pressure and the engine speed data are sensed and processed as the engine decelerates, the processing including a comparison of the pressure-speed characteristic with a standard or reference characteristic.

摘要: This disclosure relates to a system for measuring the instantaneous speed of an index point on a rotating part. The part may be a toothed gear or a wheel of an engine, and the index point may be an identifiable point on the part. The system comprises a sensor that is mounted adjacent the part, the sensor including two sensing elements that are spaced apart in the direction of movement of the point as the part rotates. As the point passes the sensor, it causes a first pulse to be produced by one element and then a second pulse to be produced by the other element. The system further includes circuitry that responds to the two time-spaced pulses and produces an indication of the time interval between the two pulses. This time interval is a function of the speed of the point which in turn is proportional to the rate of rotation of the part. In the instance where the part is attached to an engine flywheel, the time interval is also an inverse function of engine RPM.

摘要: This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine. Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are transmitted to computer processing equipment. A speed sensor responds to the movement of an engine part such as the teeth of the engine fly-wheel ring gear, and the processor calculates a function representing the change in the instantaneous engine kinetic energy. The kinetic energy change data are accumulated during an engine acceleration run and again during a deceleration run. The signals from an engine cycle event sensor are processed to indicate the firing intervals of the cylinders and thereby to correlate the engine acceleration and deceleration data. The changes in kinetic energy during the cylinder firing intervals are measured during engine acceleration, and the kinetic energy changes are again measured during deceleration, the two sets of measurements being at substantially the same engine speed. For each cylinder, the measurement on deceleration is subtracted from the related measurement on acceleration, to obtain the net work produced by each cylinder. A similar procedure may be followed to obtain the work done over segments of each firing interval, to thereby check the compression balance of the cylinders.

摘要: This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine. Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are fed to computer processing equipment. Two of the parameters are the intake manifold pressure and the engine speed. A turbocharger of the engine includes a turbine that is driven by the engine exhaust and a compressor that delivers air to the intake manifold. The performance of the turbocharger is tested by stabilizing the engine and the turbocharger at no-load, low-idle speed, quickly accelerating the engine to maximum governed speed, and determining how the turbocharger stabilizes after the engine stabilizes at the maximum speed.

摘要: Solid composite propellant compositions include at least one oxidizing agent, at least one binder, and at least one surfactant. The surfactant provides the solid propellant the property of being “self-extinguishing”, where the burning rate of the solid composite propellant as a function of pressure includes a negative pressure dependence portion, wherein the burning rate in the negative pressure dependence portion decreases with increasing pressure until a cutoff pressure is reached which results in extinguishment of the solid composite propellant. The solid composite propellant can also include at least one catalyst that modifies the burning rate of the solid composite propellant. Solid composite propellants can be extinguished without the need for depressurization by reaching a cutoff pressure, and with a tailored burning rate.

摘要: A method of scavenging oil from an oil-water mixture includes providing a plurality of functionalized fly ash particles having functionalized surfaces including reactive groups or reactive materials having hydrophobic groups covalently bound to the reactive groups or reactive materials. The oil-water mixture is contacted with the plurality of functionalized fly ash particles. The plurality of functionalized fly ash particles absorb oil from the oil-water mixture to form oil-laden fly ash particles. The oil-laden fly ash particles can be fed into a combustion process to generate heat from oil absorbed thereon, or absorbed oil from the oil-laden fly ash particles can be separated using a desorption process, and the oil recovered after separating.

摘要: Systems and methods for detection and geolocation of multiple emitters that are emitting RF signal energy on a common frequency, and that may be implemented to separate, geolocate, and/or determine the number of emitters (e.g., radio users) emitting on a common RF frequency. Real-time signal qualification processing may be employed to continuously monitor and collect incoming receiver tuner data for signal activity and ignore irrelevant noise data. Each set of data blocks from an emitter transmission signal may be defined as an emission cluster, and a set of time difference of arrival (TDOA)/frequency difference of arrival (FDOA) pairs may be computed for each emission cluster with each TDOA/FDOA pair yielding a geolocation result. A statistical qualification method may be used to produce a final geolocation answer from each set of emission cluster geolocation results, and a geolocation error ellipse computed for the final geolocation answer of each emission cluster. The final geolocation answer of each emission cluster may be run through a correlation and fusion algorithm.
