Detroit—Keeping passengers cool in the 2001 PT Cruiser was a design challenge involving efficiency. The 2.4-liter four-cylinder engine taking up only 148.2 inch3 total volume necessitated designing a special air conditioning accumulator that would fit into a confined area.
The accumulator from Parker Hannifin Corp. (Lyon, NY) uses a patented helix design that improves oil circulation. "The helix design provides a swirling and stirring motion that helps keep the oil and refrigerant mixture consistent," says Cary Horamoto, engineering manager of Parker Hannifin's refrigeration and air conditioning division. Keeping the mixture consistent reduces the amount of oil needed for charging the system, creating a cost savings for DaimlerChrysler.
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.
