Abstract: An example oil system is provided, including at least one oil chamber forming an oil sump, an oil reservoir, which is arranged separately from the oil chamber, and at least partially arranged at the same geodetic height as the oil chamber, and at least one fluid connection which connects the oil chamber to the oil reservoir.

Abstract: A method of forming an optical surface on an end portion of an optical fiber comprises inserting the optical fiber through a ferrule bore of a ferrule so that the end portion extends past an end face on the ferrule. At least one laser beam is emitted from at least one laser and directed to the end face of the ferrule. The at least one laser beam is shaped into an ellipse and comprises at least 90 percent linearly-polarized light incident on the end face of the ferrule as S-polarized light. The at least one laser is operated so that the S-polarized light reflects off the end face of the ferrule and cleaves the end portion of the optical fiber.

Abstract: A method of forming an optical surface on an end portion of an optical fiber inserting the optical fiber through a ferrule bore of a ferrule so that the end portion extends past an end face on the ferrule. At least one laser beam is emitted from at least one laser and directed to the end face of the ferrule at a location spaced from the ferrule bore.

The at least one laser is operated to cleave the end portion of the optical fiber, and the end face on the ferrule does not crack due to thermal expansion when the at least one laser is operated.

LNT catalysts are based on proton-conducting oxides of fluorite structure, namely Ca (Sr)—La—Ce (Zr, Pr) mixed oxides in which up to 40 mol-% of lanthanum is replaced by calcium and/or strontium, and up to 66 mol-% of cerium is replaced by zirconium and/or praseodymium, further combined with Pt—Pd or Pt—Pd—Rh precious metal components. SCR catalysts are Cu/zeolite modified by citrate treatment or Cu—Ce, Mn—Ce or Co—Ce/modified zeolite.

Abstract: Methods and systems are provided for regenerating a particulate filter in an engine exhaust, where burning of soot is initiated by introducing additional oxygen into the exhaust gas upstream of the particulate filter where an exhaust temperature exceeds a threshold, a soot burn rate controlled by adjusting pulsing of the additional oxygen. Further, the pulsing of the additional oxygen is introduced via a high-pressure EGR passage during boosted engine conditions.
