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.
