A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

Obama Administration wants 200-mile EV that charges in under 10 minutes

When it comes to electric vehicles, you can find issues preventing mass adoption pretty much anywhere. Which is why you can then also look for solutions pretty much anywhere. That's the method the Obama Administration announced yesterday and it involves everything from shorter charging times to more public chargers, from bigger government fleets of electrified vehicles to an "Electric Vehicle Hackathon." The new plan is looking into blistering charging speeds of up to 350 kW. Perhaps most exciting, there was a commitment made to try and increase the speed of fast charging. Today, Tesla's Supercharger network has the fastest public charging available ( up to 145 kW), but the new plan is looking into blistering speeds of up to 350 kW. That's fast enough to recharge a 200-mile EV in under 10 minutes. Another cool future was promised by the Battery500 Consortium goal, which wants to create better batteries that cost under $100 per kWh. There was no actual technology revealed at this time, but announcements like this are about new ways to approach the future, not the nitty-gritty technical details. That's why the new announcement touts the fact that 12 utilities and charging companies have committed to increase their deployment of EVs and charging infrastructure, that there are 35 new partners (businesses, non-profits, universities, and utilities) for the DOE's Workplace Charging Challenge, and that there will be an EV "Hackathon" this fall to, "discover insights and develop new solutions for electric vehicle charging." The White House's announcement comes on the heels of the first-ever Sustainable Transportation Summit (STS). The STS was sponsored by the Department of Energy (DOE) and was held earlier this month in Washington, DC. After all this activity, almost 50 companies and organizations have signed on to the new "Guiding Principles to Promote Electric Vehicles and Charging Infrastructure" document, including the usual suspects: Tesla, BMW, Nissan, Ford, General Motors, Chargepoint, the California Air Resources Board, and the State of California (notably, the usual suspects are also missing). You can read the entire announcement from the White House here, but we've put the Guiding Principles below. The Obama Administration has made strong pushes for electric vehicles before, including proposals to increase the tax credit for EV buyers to $10,000, among other things.

Feds Probe Power Steering In 938,000 Ford Midsize Cars

U.S. safety regulators are investigating complaints that the power-assisted steering can suddenly fail on three Ford midsize car models. The probe covers 938,000 Ford Fusion and Lincoln MKZ cars from the 2010 through 2012 model years, as well as the 2010 and 2011 Mercury Milan. The National Highway Traffic Safety Administration says it has received 508 complaints alleging that the cars lost power-assisted steering, causing increased steering effort. Four complaints say the problem caused crashes, but no injuries were reported. The agency says in documents posted Monday on its website that in many cases, a warning message appeared as the failure happened. Restarting the car corrected the problem in some cases, but the problem returned in others. The agency says it will check the scope and frequency of a problem. It could seek a recall. Ford says it's cooperating with the probe. Shares of Ford Motor Co. rose 6 cents to $14.65 in morning trading Monday. Its shares are down 14 percent over the past year.
