GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

Woodward Dream Cruise Photo Gallery | Classics and American muscle

The 2022 running of the Woodward Dream Cruise just went down, and we were there from morning to evening drinking in the sweet sights and pre-emissions exhaust fumes. Yes, it’s a little smelly on Woodward Ave. this time of year. Just like always, the Dream Cruise invites all comers to cruise their machines on Woodward from Ferndale, MI to Pontiac, MI. Everybody is invited, but the original intent of the Dream Cruise was to highlight classic American muscle cars. YouÂ’ll see plenty of those in our mega gallery above, but weÂ’ve sprinkled it with a bunch of other vehicle types, such as modern muscle and other intriguing American vehicles. Similar to years past, though, sometimes the classics arenÂ’t the most entertaining thing to look at on Woodward. ThatÂ’s why weÂ’ll have other mega galleries coming soon, highlighting the weird cars and (great) dogs of the Cruise, all the imports and exotics you can imagine and a special one for all the trucks of Woodward — perhaps even more so than in years past, the truck population on Dream Cruise day was quite high. Click through above to see all the classics you wouldÂ’ve seen had you been roadside on the day of the cruise. And if you missed this yearÂ’s event, make sure you check out what happens next year. You wonÂ’t be alone, as itÂ’s estimated that over 1 million people attend the Dream Cruise to either watch from the side of the road or to sit in the most glorious traffic jam in the world.
