Engineers at Ford are testing a new hydrogen fuel internal combustion engine (H2ICE) that reduces noxious emissions by 99.7% compared to gasoline combustion engines of similar size and power. Ford's P2000 research vehicle emits mostly water vapor and a small amount of carbon dioxide from the exhaust. It would take 300 hydrogen-powered vehicles to emit the same amount of carbon dioxide that comes from a single gasoline engine. "We made big improvements to this hydrogen engine by increasing the compression ratio and reducing oil consumption," says William Stockhausen, a staff technical specialist on Ford's H2ICE project. Other improvements include adding a solid-film lubricant and hard-surface treatments to the fuel injector system and a triple-redundant safety system. "We wanted to err on the side of safety," says Stockhausen. The P2000 H2ICE uses a modified Zetec 2.0-liter engine. Ford test results indicate the new engine is 25 to 30% more efficient than its gasoline counterpart. Ford's web site address is www.ford.com.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
