A new twist.Maybe it's the name. Maybe it's the piece of art that came with the press release. Either way, Dana Corp.'s (Toledo, OH; www.dana.com) "MultiTwister" air/oil separator is "an axial cyclonic separator that extracts oil particles from the engine air stream during operation for cleaner combustion." This means the double helix double helix n. The coiled structure of a double-stranded DNA molecule in which strands linked by hydrogen bonds form a spiral configuration. Also called DNA helix, Watson-Crick helix. "twister channels" spin the oil mist in tight spirals along their length to create turbulence and pressure that forces oil droplets against the channel walls and returns them to the crankcase crank·case n. The metal case enclosing the crankshaft and associated parts in a reciprocating engine. crankcase Noun the metal case that encloses the crankshaft in an internal-combustion engine . The particulates, on the other hand, coalesce co·a·lesce intr.v. co·a·lesced, co·a·lesc·ing, co·a·lesc·es 1. To grow together; fuse. 2. To come together so as to form one whole; unite: on the channels. Dana says it can integrate the MultiTwister into its thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. and thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. cylinder head covers, which prevents freezing in extreme weather. Plus, by preventing the oil from entering the combustion chamber where it would be burned, emissions are reduced and the life of major components (turbochargers, catalysts, inlet valves, carbon particulate filters, etc.) is increased.
