Abstract: The present invention discloses a hydrate energy-storage temperature-control material and a preparation method therefor. The material includes a refrigerant hydrate and a cross-linked polymer. The preparation method comprises the following steps: first, preparing a refrigerant hydrate by using a high-pressure reactor, and conducting grinding, crushing and sieving to obtain hydrate particles; then, uniformly spraying polytetrafluoroethylene suspended ultrafine powder onto the surface of the hydrate particles by using an electrostatic spraying device, and putting the hydrate particles into a plasma instrument to modify polytetrafluoroethylene so as to allow free radicals to be formed on the polytetrafluoroethylene powder surface; finally, subjecting monomers to graft polymerization with the free radicals on the polytetrafluoroethylene surface under the irradiation of a high-pressure mercury lamp of UV lighting system to stabilize the structure of the material, preparing a final product.

Abstract: A method and system for modeling growth of reductant deposits for an aftertreatment system on a real time basis using input including exhaust gas temperature, exhaust gas flow rate, and reductant dosing rate. The growth of the reductant deposits are affected by a rate at which reductant accumulates and decomposes from a surface of the aftertreatment system. Thus, the method and system disclosed determines a net reductant deposit growth rate value based on a reductant deposit accumulation rate value and a reductant deposit decomposition rate value. Further, the method and system disclosed determines a reductant mass deposit value based on the net reductant deposit growth rate value. The reductant mass deposit value determined by the method and system may then be used to control a regeneration strategy of the aftertreatment system to eliminate the reductant deposits from the aftertreatment system.
