Hybrid energy absorbing assembly for attachment to a vehicle for a vehicle, comprising a bumper beam comprising a plastic material; and a towing assembly, wherein the towing assembly comprises a metal insert. The invention also relates to a metal insert for such a hybrid energy absorbing assembly. Moreover, the invention relates to a vehicle provided with such a hybrid towing bumper beam assembly, wherein the metal insert is connected to a body-in-white of the vehicle. Furthermore, the invention relates to a method for manufacturing such a hybrid towing bumper beam assembly for a vehicle, the method comprising placing the metal insert in a mold; introducing molten thermoplastic material, to a mold to in site form the energy absorbing assembly and thus overmolding the metal insert with the thermoplastic material, thereby embedding the metal insert in the bumper beam.

The present invention is about a bumper beam comprising: —a first end portion and a second end portion, —a center beam contiguous with and oriented between the first end portion and the second end portion, wherein the center beam comprises a front face and a back face; wherein the center beam has a center section and end sections at opposite ends of the center section, the end sections being adjacent to the end portions, respectively, wherein the center beam comprises horizontal and vertical ribs extending from the front face and the back face and/or between the front face and the back face, wherein the bumper beam is made of a plastic material.

Disclosed herein is an energy absorber having excellent impact resistance and excellent impact energy absorbability. The energy absorber includes an olefin-based resin composition obtained by mixing an olefin resin, a polyamide resin, and an elastomer having a reactive group that reacts with the polyamide resin, wherein the olefin-based resin composition has a continuous phase containing the olefin resin and a polyamide resin-based dispersed phase dispersed in the continuous phase, and the polyamide resin-based dispersed phase has a structure in which the elastomer is contained in a matrix phase containing the polyamide resin.

ABS thermoplastic molding compositions for the preparation of blow molded articles in the automotive and household sector comprising (A) 30 to 40 wt.-% ABS graft rubber copolymer, (B) 25 to 35 wt.-% alpha-methylstyrene/acrylonitrile copolymer, (C) 30 to 40 wt.-% styrene/acrylonitrile copolymer, (D) 0.05 to 0.50 wt.-% homo- or copolymer comprising monomer structure units with a C.sub.3-C.sub.6-alkyleneoxide side chain having an epoxy terminal group or with a modified, functionalized C.sub.3-C.sub.6-alkyleneoxide side chain, and (E) 0 to 5 wt.-% further additives. Component (D) is preferably polyglycidylmethacrylate.

The invention provides an exhaust purification device capable of suppressing the temporal decrease in NOx catalyst removal efficiency due to soot accumulation. The invention provides an exhaust purification device using an air injection nozzle to inject pressurized air into a casing of a catalyst reactor containing an NOx catalyst as a catalyst and removing soot adhering to the NOx catalyst, wherein it is determined and externally notified that there is abnormal deterioration in the NOx catalyst when the pressure difference P in exhaust between the upstream and downstream sides of the NOx catalyst has increased by at least a first reference pressure difference increase Pt1, which is the allowable amount of pressure difference increase, above the pressure difference Pi in exhaust between the upstream and downstream sides of the catalyst in the initial state at the same exhaust flow rate Ve.
