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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
