Emissions regulations around the globe are tightening, so engine makers and refineries will be scurrying to meet requirements. Diesel engines are evolving to provide lower emissions, using both mechanical and electronic techniques, and refineries are going to require upgrades, particularly in the U.S.
"The U.S. fuels have an average cetane number of 44. That's the world's worst, including emerging countries," says Loren Beard, senior manager at DaimlerChrysler Environmental and Energy Planning in Auburn Hills, MI. The cetane number measures the ignition quality and efficiency of diesel fuel.
Speakers at the recent Diesel Engine Emissions Reduction conference in Chicago detailed the many approaches to meeting emissions requirements, which all require a move to low sulphur fuels. Engine designers are watching the international moves closely, since engines must operate on these fuels. "
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.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
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.
