Abstract: A propulsion device contains a working mass within an enclosed plenum, where the working mass is circulated through the plenum to produce a net force vector. The working mass is accelerated around a first bend or change in direction within the plenum by a working mass driver. The temperature of the working mass is then reduced and the working mass is slowed. The working mass is then accelerated around a second bend or change in direction within the plenum resulting in two opposing force vectors. When combined, the two opposing force vectors produce a net force, and thus, acceleration of the propulsion device.

Abstract: The present invention provides systems and methods to improve the performance and emission control of internal combustion engines equipped with nitrogen oxides storage-reduction (“NSR”) emission control systems. The system generally includes a NSR catalyst, a fuel processor located upstream of the NSR catalyst, and at least one fuel injection port.

The fuel processor generally includes one or more catalysts, which facilitate reactions such as combustion, partial oxidation, and/or reforming and help consume excess oxygen present in an engine exhaust stream. The methods of the present invention provide for NSR catalyst adsorbent regeneration. Control strategies are provided to control the system and methods of the invention.

Abstract: A system and method of achieving ride control for a work vehicle that replaces a traditional accumulator with a ride control valve, a directional control valve and a fluid pressure source. The fluid pressure source may be a variable displacement hydraulic pump. The ride control valve is set to a first relief pressure that allows fluid to flow from the head end of a hydraulic cylinder when the loading on the cylinder, i.e., the pressure in the head end is equal to or greater than the first relief pressure. A work tool of the vehicle falls from a first position to a second position when fluid flows from the head end. The ride control valve is then reset to a second relief pressure, higher than the first relief pressure and sufficient to move the work tool toward the first position. Afterwards, the directional control valve is opened long enough to allow fluid from the fluid pressure source to enter the head end and move the work tool back to approximately the first position.
