Latest Patents
One of Smith's latest innovations is a seal assembly with an interlocking load ring. This face seal assembly comprises a pair of confronting seal rings that have mutually-engaging seal faces. The seal faces are maintained in sealing engagement by a pair of resilient load rings positioned between the seal rings and a pair of housings on opposing sides. The load rings are designed to interfit with one another, effectively resisting relative rotation.
Another significant patent is the after-injection combustion exhaust purification system and method. This invention is particularly suited for purifying exhaust from large lean burn diesel engines. The emissions purification system facilitates an after-injection of fuel through the engine fuel injector during the exhaust stroke. A computer controls the injector to optimize the amount of NOx reducing fuel injected, achieving optimal NOx reduction rates while maintaining acceptable HC emissions levels.
