Abstract: A device and method for producing a porous fiber structure. One or more points of high surface curvature is produced in a liquefied polymer, such as a polymer solution or a polymer melt. The points of high surface curvature may be produced by forcing the liquefied polymer through narrow nozzles, or by wetting sharp protrusions with the liquefied polymer. The liquefied polymer is charged to a high negative electrical potential relative to a grounded moving belt. Thin jets of liquefied polymer emerge from the points of high surface curvature to impinge as fibers on the moving belt, thereby forming an unwoven fiber structure of relatively uniform porosity. A powdered aerosol is charged to a high positive electrical potential relative to the moving belt. As the belt moves past the aerosol, the aerosol particles are attracted to fill interstices in the fiber structure, thereby creating a composite filtering material.

Abstract: Disclosed is a means for reducing jet engine exhaust noise wherein mixing is enhanced between adjacent exhaust flows and between exhaust flow and free-stream flow. Also disclosed is a means for improving the thrust of jet engines and for reducing the noise and drag of aircraft. The device is a segmented, triangular or trapezoidal shaped, curved extension to a nozzle's sleeve or surface trailing edge that results in a serrated trailing edge. The extensions enhance the natural free mixing of the adjacent flows and therefore reduce the acoustic energy associated with the velocity differences between the streams in which they are imbedded. The novel structure forces adjacent flows to penetrate into one another to a greater depth than that achieved with free mixing and results in a more uniform flow in a shorter stream wise distance. As a result of the enhanced mixing, drag on flow surfaces that are downstream of the devices and are scrubbed by the flows adjacent to the devices can be reduced.

Abstract: An exhaust gas recirculation (EGR) system of an internal combustion engine has an EGR cooler in an EGR passage connecting an exhaust manifold with an intake manifold. The EGR cooler cools EGR gas recirculated through the EGR passage. Cooling performance detecting means included in an electronic control unit (ECU) determines that cooling performance of the EGR cooler is degraded when intake pressure measured by an intake pressure sensor is lower than a normal intake pressure by at least a predetermined value. When the degradation of the cooling performance is detected, cooling performance regeneration controlling means included in the ECU increases the temperature inside the EGR cooler by heating the exhaust gas to eliminate soot or unburned hydrocarbon by oxidization. Thus, the cooling performance of the EGR cooler is regenerated.

Abstract: When determining a maximum storable oxygen amount of a catalyst disposed in an exhaust passage, a target air-fuel ratio of the gas upstream of the catalyst is set to a predetermined lean air-fuel ratio upon determining that the output of a downstream-side air-fuel ratio sensor indicating a lean air-fuel ratio has changed to indicate a rich air-fuel ratio. Then, a feedback correction amount is calculated such that the air-fuel ratio detected by an upstream-side air-fuel ratio sensor matches the target air-fuel ratio, and a feed-forward amount required for the gas, to be supplied into the internal combustion engine, to become lean is determined. A final injection amount is determined by correcting the feed-forward amount by the feedback correction amount.
