Motor Coach Industries (MCI) of Schaumburg, IL, finished a 54-day cross-country eco-journey that covered 8,600 miles and visited 26 U.S. cities, six national parks and six Native American communities. The bus builder teamed with Vermont’s Lamoille Valley Transportation and took 13 scholars from the Udall Foundation on a promotional tour to show off “green” transportation.
The students rode in an MCI J4500 LX motor coach equipped with a 2007 clean-diesel Caterpillar engine fueled with a 20-percent biodiesel, 80 percent ultra-low sulfur diesel blend. The bus also featured tools that monitored its emissions levels. Those who traveled on the bus posted video blogs about the journey on its website: Udall.gov. The American Bus Assn. claims even using conventional fuels, fully occupied motor coaches use less energy per passenger mile than planes, trains or cars.
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.
