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.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
