Clean-diesel engines are matching — even surpassing — the performance of conventional auto engines. The Bosch Group of Farmington Hills, MI, is running race cars powered by clean diesel engines — and they're winning. Bosch supplies high-pressure pumps and piezo-inline injectors for the diesel common rail injection system on the Audi R10 TDI racing car. The introduction of diesel technology to the Audi R10 made racing history when it became the first diesel-powered engine to win the 24 Hours of Le Mans. That feat continues this year as the Audi R10 leads its race class in the American Le Mans Series.
Bosch's diesel technology is also available in passenger cars. "The success we've seen both on and off the race track proves that clean diesel technology is a powerful and viable powertrain solution that offers consumers improved fuel economy, reduced emissions and increased performance," says Chris Qualters, director of marketing for North American Diesel Systems at Bosch. The company estimates the North American market for light diesel vehicles will reach 15 percent by 2015. According to R.L. Polk and the Diesel Technology Forum, registrations for diesel-powered vehicles rose 80 percent between 2000 and 2005, from 300,000 to 545,000 vehicles.
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.
