Manufacturing an internal combustion engine from extruded aluminum alloy rather than conventional casting offers many benefits, including big size and cost savings. So says Power Beat International Ltd., a research and development company based in Hamilton, New Zealand. Powerbeat's ALU-X(TM) engine employs interlocking sectioned extruded profiles to form the engine block. Replacing one-piece cast blocks, the company claims, allows engines of different capacities, cylinder numbers, and stroke lengths to be made from the same parts. Engine assembly is quick and easy: Tie bolts hold stressed components in compression, eliminating the need for load bearing threaded holes within the block; tee slots incorporated into the extrusion profile allow simple attachment of auxiliary components. Other benefits include superior grain structure for accurate bores and finishes; lower capital costs, higher production capacity; high power-to-weight ratio. Power Beat International is currently developing 200-cc versions of the ALU-X to suit the small engine market. Contact Evan Bydder at firstname.lastname@example.org or call +64-7-843-0011.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
