A liquid cooled fuel injection valve is operable to inject fuel directly into a combustion chamber through a nozzle orifice provided in an injector tip. The fuel injection valve further comprises a cooling system for draining fuel from a fuel cavity disposed within the injector tip and a drain valve that opens when pressure within the fuel cavity is greater than a predetermined set point. Fuel drained through the cooling system is directed to a drain system that may be combined with drain passages typically found in fuel injection valves. In a preferred embodiment, the drain valve is disposed within the fuel injection valve.

A vehicle wheel illumination system is a device having four separate light assemblies that are affixed above a tire and within the wheel well above the respective tire. Each light assembly includes a housing formed from a base, a wall and a cap that is removable. The base houses the electrical wiring that is coupled with a bulb stem. A bulb is inserted into the bulb stem to provide illumination. The cap includes a translucent lens through which the illuminated bulb is transmitted. The housing further includes mounting means for attaching the housing to the wheel well. The electrical wiring is further coupled to the electrical system of the automobile.

The invention relates to a method for recycling at least one mixed PET plastic article, the method comprising degrading at least PET of the mixed PET plastic article to monomers and / or oligomers using an enzyme and recovering the resulting monomers and / or oligomers. The method of the invention may be used for depolymerizing, simultaneously or sequentially at least two different polymers of the mixed PET plastic article, and / or for recycling at least two mixed PET plastic articles.

An inexpensive and durable polyelectrolyte composition includes both an aromatic polymer containing carbonyl linkages and / or sulfonyl linkages in the backbone chain and bearing cation-exchange groups and a fused salt exhibits a high ionic conductivity even in the absence of water or a solvent. The aromatic polymer is preferably an aromatic polyether sulfone comprising specific structural units and bearing cation-exchange groups, an aromatic polyether ketone comprising specific structural units and bearing cation-exchange groups, an aromatic polyether sulfone block copolymer consisting of at least one hydrophilic segment bearing cation-exchange groups and at least one hydrophobic segment free from cation-exchange groups, and / or an aromatic polyether ketone block copolymer consisting of at least one hydrophilic segment bearing cation-exchange groups and at least one hydrophobic segment free from cation-exchange groups. The use of such a block copolymer as the aromatic polymer gives polyelectrolyte compositions which are excellent in maintenance of structure even at high temperature.
