An extruded-aluminum four-cylinder prototype IC (internal combustion) engine, demonstrated late last year, took less than seven months to deve-lop. Power Beat Intl. Ltd. claims the technology provides the following advantages for engine design and manufacture:
- High efficiency
- Low cost
- Light weight
- Less engine noise
- Fewer parts than conventional designs
The engine, code named ALU-X(TM), uses an extruded-aluminum cylinder block, crank case, head, and sump "plate," all held together with tie rods. Also, piston valves replace poppetvalves and allow for a side valve arrangement that increases theefficiency of the engine, reducesnoise, extends overall life and reduces engine height compared to overhead valve engines.

Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
