Abstract: Various methods and systems are provided for an engine with an exhaust gas treatment system. In one example, under a first condition, a first fuel is delivered for combustion in the engine. Under a second condition, a second fuel is delivered for combustion in the engine, the second fuel different than the first fuel. Under a third condition, the first fuel is delivered as a reductant for the exhaust gas treatment system.

Abstract: A method of operating an engine comprises introducing into a cylinder volume a non-compression-combustible fuel, such as natural gas, a compression-combustible fuel, such as diesel, and an oxidant and mixing the components for greater than about 275 microseconds, prior to compression combusting the compression-combustible fuel. The mixing may be done such that the two fuels are at least partially homogenized in the cylinder volume. By mixing, or premixing, the two fuels prior to combustion, the compression-combustible fuel is then simultaneously combusted via compression at multiple ignition points in the volume. The second, non-compression-combustible fuel is ignited in response to the combustion of the first fuel. An engine that enables the various methods is also disclosed.

Abstract: The present invention relates to airfoils, and in particular turbine blades and vanes, having cooling slots that are angled from a line of reference to effect metering of cooling air through the cooling slots thereof. This metered cooling airflow also creates a more stable film cooling layer about the surface of the airfoil.

Abstract: A turbine airfoil includes pressure and suction sidewalls extending axially in chord between opposite leading and trailing edges. The sidewalls are spaced transversely apart to define flow channels extending longitudinally and separated chordally by partitions bridging the sidewalls. A perforate partition includes a row of crossover holes extending obliquely therethrough.
