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.
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
