  • Patent number: 10641152
    Abstract: A control system is provided to a reductant dosing system for actively maintaining the reductant dosing system ready for use by flushing unused reductant that has crystallized at a return valve of the reductant dosing system. The control system includes a controller that can control a manner of operation of specific system hardware that is present in the reductant dosing system to flush the unused reductant from the return valve that could otherwise cause the return valve to remain a flow-blocking condition as a result of the crystallized reductant.

  • Publication number: 20200094517
    Abstract: Fiber reinforced composites are made by infusing a mass of reinforcing fibers with a resin composition (11). A thin sheet (6) of nano-sized monofilaments (7) is applied on at least one major surface of a fiber mass. The resin composition (11) is subsequently hardened to form the composite. This method produces a composite having a very smooth surface. Printout of the reinforcing fiber is greatly reduced without the need to mask it through the application of thick coatings or additional layers of material.
