Abstract: A powertrain control unit may be configured to control an engine and identify a first operating condition is expected to fulfill a demand for output with an exhaust stream having a first amount of a pollutant (e.g., NOx, particulate matter), and a second operating condition expected to fulfill the demand with an exhaust stream having a reduced amount of the pollutant as compared to the first amount. The powertrain control unit may receive duty cycle information to control the engine to fulfill the demand per the second operating condition, yielding the reduced amount of pollutant in the exhaust. Duty cycle information may include speed, location, position, rotation, temperature, and/or other information. A vehicle, backhoe, bulldozer, crane, and/or combine harvester may comprise the powertrain control unit and an engine and aftertreatment system. An exhaust aftertreatment system may be remotely activated, which may reduce warmup time associated with emissions mitigation.

Abstract: An engine control system configured to operate an engine is configured to predict an expected duty cycle including an expected demand from the engine, and calculate two or more future operating conditions, each future operating condition including engine control parameters that, when used to control the engine, are expected to result in the engine meeting the expected demand. One of the future operating conditions is selected, and a present operation of the engine is adjusted in response to the selected future operating condition. A vehicle and/or offroad diesel apparatus may comprise the engine control system.

Abstract: A vehicle comprising a (diesel or gasoline) engine and aftertreatment system includes a powertrain control unit that identifies engine operating conditions expected to fulfill a demand for output from the engine. A first operating condition is expected to fulfill the demand with an exhaust stream having a first amount of NOx. A second operating condition is expected to fulfill the demand with an exhaust stream having a reduced amount of NOx as compared to the first amount of NOx. The powertrain control unit receives duty cycle information to control the engine to fulfill the demand per the second operating condition, yielding the reduced amount of NOx in the exhaust. Duty cycle information may include vehicle speed, location, a position sensor, a rotation sensor, ambient temperature, a characteristic feature of the duty cycle, dependency of load vs. time, information regarding an historical duty cycle, and temporal dependence of demand.

Abstract: Systems and methods provide for forming layered structures. Textured tapes may be fabricated, having cast and/or embossed patterns that provide for desired flow characteristics in an assembly of stacked, rolled, and/or otherwise assembled tapes. In some cases, shear thinning materials may be formed into textured tapes using localized shear stress to induce shear thinning during a pattern formation. A pattern may be maintained after removal of the shear force due to the high viscosity of the material at low shear stress.

Abstract: Systems and methods for treating a fluid with a body are disclosed. Various aspects involve treating a fluid with a porous body. In select embodiments, a body comprises ash particles, and the ash particles used to form the body may be selected based on their providing one or more desired properties for a given treatment. Various bodies provide for the reaction and/or removal of a substance in a fluid, often using a porous body comprised of ash particles. Computer-operable methods for matching a source material to an application are disclosed. Certain aspects feature a porous body comprised of ash particles, the ash particles have a particle size distribution and interparticle connectivity that creates a plurality of pores having a pore size distribution and pore connectivity, and the pore size distribution and pore connectivity are such that a first fluid may substantially penetrate the pores.

Abstract: Computer implemented methods may create unique hardware platforms suitable for providing and/or using testing protocols. A new protocol may be designed using a target protocol, such that the new protocol replicates one or more aspects of the target protocol. The new protocol may incorporate a certain diversity, which may make it more difficult for an entity being tested (e.g., a car, a truck, a person) to “cheat” the test (e.g., using knowledge of the target protocol). A new protocol may be calculated, validated, and provided “on demand.” A new protocol may be tailored to a particular set of test results (e.g., to highlight an apparent deviation between expected and actual results).

Abstract: Systems and methods for fabricating bodies (e.g., porous bodies) are described. Various aspects provide for reactors and the fabrication of reactors. Some reactors include surfaces that provide for heterogeneous reactions involving a fluid (and/or components thereof). A fluid may be a gas and/or a liquid. A contaminant in the fluid (e.g., a dissolved or suspended substance) may react in a reaction. A contaminant may be filtered from a fluid. Some reactors provide for independent control of heat transfer (between the fluid, the reactor, and the environment) with respect to mass transfer (e.g., fluid flow through the reactor).

Abstract: Various aspects provide for disposing an umbrella over a table. In some cases, an umbrella may be coupled to a table. An umbrella may be disposed at a location other than a center of the table, which may provide for improved shelter from weather arriving at an angle (e.g., wind-driven rain, angled sunlight, and the like).

Abstract: Aspects provide for an engine and an aftertreatment system coupled to the engine and configured to treat an exhaust stream from the engine. The engine may be incorporated into a mobile piece of equipment (e.g., a truck). A fairing may be shaped to improve air flow during motion by reducing air resistance created by the aftertreatment system.

Abstract: Heat from an ex-vessel mass of core material is removed to cooler regions of a containment envelope via liquid and/or vapor phase transport. Various aspects provide for contacting the ex-vessel core material with a material having properties including melting point, boiling point, and condensation kinetics such that condensation of the material in cooler regions of the containment envelope is at least as fast as evaporation of the material due to heat absorption from the core material and associated species.
