Abstract: A PM catalyst regeneration control for the purpose of “soot removal” is performed prior to a sulfur poisoning recovery control. In the PM catalyst regeneration control, PM deposits in a catalyst are burned. A target throttle opening degree for the sulfur poisoning recovery control is preset smaller than a target throttle opening for the PM catalyst regeneration control in order to reduce the intake air volume during deceleration. A catalyst bed temperature is thus prevented from dropping, and therefore maintained at a level appropriate to sulfur poisoning recovery. Controlling the intake air volume during deceleration in such a manner results in more efficient catalyst recovery from sulfur poisoning, so that the fuel economy is maintained during the sulfur poisoning recovery control.

Abstract: A vehicle is provided with a diesel engine, an exhaust treatment system including a LNT, and a controller configured to control the provision of a reductant to the exhaust for regenerating the LNT. The controller selectively provides the reductant to the exhaust based in part on a measure of whether the engine is undergoing a change in operating state. Preferably, the measure indicates if the engine is undergoing a speed or torque increase. During these types of transients, ideal conditions for LNT regeneration often occur. Ideal conditions include low exhaust oxygen concentrations combined with relatively low exhaust flow rates. Regenerating preferentially when these ideal conditions occur reduces the fuel penalty associated with LNT regeneration. These conditions also simplify regulating LNT and reformer temperatures. In a related concept, the transient is artificially created.

Abstract: An engine output controller provided in a bulldozer includes an output curve storage device storing a plurality of output curves of an engine and an output curve changing device selecting and shifting to one of the plurality of output curves. The output curve changing device, when a pressure of a blade tilt cylinder is equal to or more than a predetermined value, calls and shifts to a higher output curve from the output curve storage device. When an oil pressure is supplied to the tilt cylinder to tilt a blade and an operation is performed without reducing a soil pressing speed in this condition, the output curve changing device shifts the current output curve to the higher output curve to drive the engine. However, in many other cases, the output curve is automatically switched to a lower output curve to reduce an output of the engine. Thus, the fuel consumption is improved.

Abstract: A cool-air supplying apparatus of a refrigerator includes a fan that has a body and a plurality of blades mounted around a circumference of the body. A motor of the cool-air supplying apparatus is mounted at least partially in a recess formed within the fan body. A rotor of the motor is coupled to the inner surface of the recess so that the fan and rotor rotate together as one body. Because the motor is mounted within a recess of the fan body, an overall height of the combined fan and motor is smaller than in conventional cool-air supplying devices. As a result, when the cool-air supplying apparatus is mounted within a cool-air supply duct of a refrigerator, more space within the refrigerator can be devoted to the storage space, which increases the internal capacity of the refrigerator. In addition, less room within the cool-air supply duct is consumed by the motor, which increases the flow of cool air through the duct.

Abstract: A method of liquefying a hydrocarbon-rich gas, wherein the gas flows through a cascade of three refrigeration stages, each stage comprising a refrigerant circuit and a compressor, wherein at least part of the flow of refrigerant from the second circuit is used for the pre-cooling of the hydrocarbon rich gas in the first refrigeration stage. This balances the load on each of the compressors. By standardizing the drive units and compressors of the three coolant circuits, it is possible to maximize the attainable liquefaction capacity of the liquefaction process using tried-and-trusted drive units and compressors respectively. This method can be applied to mixed refrigerant cascades and circuits with a carbon dioxide pre-cooling circuit. This latter option has benefits for offshore use where large amounts of hydrocarbons are undesirable.

Abstract: Two methods have been developed for producing a glycoluril slow release fertilizer suspension product. Urea and glyoxal are reacted at a urea to glyoxal mole ratio between 2.0 and 8.0. One or more mineral acids are added between 10 and 30 percent by weight of the formulation and heated between 80 and 100 degrees C. until 70% or more of the glyoxal has been converted to water insoluble glycoluril particles. The pH may be adjusted with an inorganic base, primary fertilizer nutrients added, and a suspending agent is admixed to form a stable suspension. A “green chemistry” method requiring no heat also yields a stable product at room temperature by mixing all the materials and immediately placing the product in storage. The glycoluril product forms during storage in high yield. As such, the liquid glycoluril fertilizer suspensions are stable and easily applied through liquid application, or can be used as a raw material component of a granulated fertilizer product.
