The invention provides a variable speed hydraulic pump designed to operate at a maximum horsepower throughout its pressure range by adjusting motor speed according to motor load parameters. In particular, the variable speed hydraulic pump includes a hydraulic pump unit coupled to a variable speed electric motor by a drive unit and to a hydraulic fluid tank for pressurizing and pumping hydraulic fluid when operated by the motor. A motor controller is electrically connected to the motor to supply drive signals to the motor based on electrical characteristics of the drive signals which are dependent on the load exerted on the motor. Suction from the load is provided by both the main pump and a bidirectional supercharging pump by reversing the direction of the motor and shifting a 4/3 valve to connect the main pump inlet to the load and its outlet to tank. In addition, the controller reduces the motor speed at the maximum rated pressure to just maintain the pressure, to reduce the amount of fluid pumped through the maximum pressure relief valve.

This disclosure relates to a hybrid electrical drive system for a vehicle, and in particular, to a conversion kit for converting a vehicle with a standard internal combustion engine into a hybrid electrical vehicle. The conversion kit is designed to increase the fuel efficiency and travel range of the vehicle so converted, and to provide additional horse power upon acceleration. The system utilizes a novel arrangement to intercept kinetic energy that would normally be wasted as the vehicle is decelerating or braking. The system converts the kinetic energy to electrical energy to recharge an on board electrical energy supply source for use in assisting with the acceleration of the vehicle.

A fuel system is provided for generating hydrogen and oxygen for use in an internal combustion engine to improve combustion efficiency, horsepower, and torque and to decrease emissions. The fuel system has at least one electrolysis cell for generating hydrogen and oxygen by electrolysis of an aqueous solution, a power source for providing electrical power to the electrolysis cell, and a heating and cooling system for maintaining the temperature of the electrolysis cell in a desired range to obtain the desired quantities of hydrogen and oxygen for operation of the internal combustion engine. The invention also includes an electrode array of a plurality of spaced apart electrodes for use in this fuel system and a nonconductive support connected to each of the electrodes to hold the electrodes in place, while leaving adequate room around the electrodes to allow free flow of the aqueous solution between the electrodes. High purity electrolyte and substantially non-reactive electrodes result in improved electrolysis.

Method, apparatus and article of manufacture for monitoring and characterizing the operation of a transducer (i.e., motor or pump) downhole. In particular, transducer RPMs are determined by analysis of acoustic information. An acoustical source (signal generator) located on a downhole tool (e.g., a drill string) creates acoustic energy which is received and processed by a receiving unit, which may be located at the surface of a wellbore. The acoustical source is operably connected to the transducer, so that the frequency of the signal produced by the acoustical source corresponds to the speed of the transducer. The acoustic signal of the acoustical source may then be isolated from other acoustical energy produce by downhole equipment, such as a drill bit. Having determined transducer speed by isolation of the acoustic signal, other operating parameters may be determined. Illustrative operating parameters include torque, flow, pressure, horsepower, and weight-on-bit.

In construction machinery, control is conducted to keep a work machine to operate at a constant speed regardless of the operation thereof. Different engine output lines T0-T3 and pump torque lines M1-M4 are defined for different operation types. All the matching points of the engine output lines T0-T3 and pump torque lines M1-M4 designate a constant engine speed N1. One engine output line and one pump torque line are selected according to the operation type presently selected. An output horsepower of the engine is controlled on an equal horsepower line corresponding to a sum of a horsepower for an auxiliary machine and a horsepower at a matching point of the selected lines. The pump torque for the work machine is controlled on the selected pump torque line. The engine operates at a constant speed N1 even when the operation type varies or the horsepower for the auxiliary machine changes.

A variable displacement reciprocating pump with pumping rate that is adjustable from zero to maximum stroke while the pump is running. Stroke is varied by changing relative position of pairs of eccentric inner and outer cams that drive the pump's plungers. The pump's input drive shaft drives two gear trains: a first gear train that turns the inner cams and a second gear train that turns the outer cams. These cams normally revolve together with no relative motion occurring between them. A rotary actuator is positioned in the first gear train to rotate the inner cams relative to the outer cams and thereby changes the pump's stroke. A computerized system of sensors and control valves allows the pump to be automatically controlled or limited to any one or combination of desired output flow, pressure and horsepower.

A method is disclosed for controlling overall transmission ratios in a vehicle powertrain with an engine, fixed multiple-ratio gearing and infinitely variable ratio components.

This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15). We protect homeowners, their cars and their plows from injury when plows strike hidden objects. Protection devices comprise safety springs (60) and pivots (63, 67 and 69) of FIG. 3B, the tension-release mechanism mentioned but not detailed in FIG. 15, annor shields (396, 398) of FIG. 16 and various others mentioned or provided for in our drawings but not detailed. We prefer cars' chassis tie-down ears (72) in FIG. 3A, as connector points for our plow or thrower arms. For cars lacking such ears, we propose add-on ears. For example, tie-down ear (126) in FIG. 6.

A consist controller is provided that enables an operator to take advantage of all horsepower combinations for locomotives in a consist. The consist controller provides a fractional increase option and a fractional decrease option that enables the operator to increase or decrease horsepower output with finer adjustments. In a preferred implementation, the fractional increases and decreases are used in conjunction with a fuel optimization routine such that the target setpoint, from which a range of horsepower values is computed, can be increased or decreased in steps that are less than a full notch increase or decrease.

Internal combustion engines, both compression ignition (CI) and spark ignition (SI), four cycle and turbocharged, are defined with the proposed patented modifications to improve environmental acceptability. Thermal efficiency has been more than doubled at the maximum power design point. The CI engine 75.8 percent and the SI engine 72.7 percent. The particulates (smoke), nitrus oxide, and carbon monoxide have been reduced to a trace for both engine types. With the improved thermal efficiency the carbon dioxide produced per horsepower is less than half of the current designs. Exhaust noise and obnoxious smell has been eliminated for both engine types. These predicted improvements are based on the use of existing fuels. A byproduct of the design will be the recovery of the distilled water resulting from the products of combustion.
