  • Publication number: 20250052182
    Abstract: The exhaust structure comprises an exhaust pipe through which exhaust gas flows, a urea water injector that injects urea water, a SCR catalyst provided downstream of the injection position of the urea water, and an attachment member for fixedly attaching the urea water injector to the exhaust pipe. The attachment member is a cylindrical body passing through in the axial direction, and is attached to the exhaust pipe such that a nozzle hole of a urea water injector is disposed in one opening part and the other opening part faces the inside of the exhaust pipe on the upstream side of the SCR catalyst. The inner peripheral surface of the attachment member is provided with a rib that causes exhaust gas flowing from the other opening part to the one opening part to change direction so as to flow from the one opening part to the other opening part.

  • Publication number: 20220135764
    Abstract: The present invention aims to obtain a resin composition with low thermal expansion property by suppressing functional deterioration in negative thermal expansion property when a negative thermal expansion material is added to a thermoplastic resin and heat-processed. The present invention provides a resin composition including metal oxide particles and a thermoplastic resin, both having a negative thermal expansion property. The negative thermal expansion of the particles is attributed to a crystal phase transition, which is driven by electron transfer between the constituent metals, and a covalent protective layer that inhibits the electron transfer is formed between the particles and the thermoplastic resin.
