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.

Chevy will reveal the Bolt EV tomorrow at CES

The moment that electric vehicle consumers and green propulsion enthusiasts have been waiting for is almost upon us, as Chevy confirmed that it will unveil the production version of the 2017 Bolt EV Wednesday at CES in Las Vegas. Chevrolet previewed the Bolt in concept form at the Detroit Auto Show almost a year ago, proposing a compelling rival to the likes of the Nissan Leaf and BMW i3. We've expected the CES debut for awhile, and Chevy projects that the finished product will boast a range of more than 200 miles on a single charge. That's nearly double the Leaf's range, and significantly farther than the i3 will travel even with the Range Extender kicking in. All of that for under $30,000 after federal tax credits. Of course, Chevy's own Spark EV costs much less, but will only go 82 miles before it needs to plug in again. If you won't be in Vegas for the unveiling tomorrow, you can catch it on Facebook. It will be the first vehicle to debut on the new Facebook Live, featuring both a live video stream and a 360-degree interactive interior video. Once out on the market, the Bolt EV will join the Spark EV, Volt PHEV, and Malibu hybrid in a growing array of electrified vehicles from the American automaker, rivaling the likes of Toyota and Nissan for the most electrified vehicles in its lineup. Chevrolet Bolt EV Will Debut at CES 2016-01-05 DETROIT – Chevrolet will unveil the 2017 Bolt EV at the International Consumer Electronics Show (CES) in Las Vegas on Wednesday, Jan. 6, and be the first auto brand to work with Facebook to debut a vehicle using Facebook Live. With the addition of the Bolt EV to a lineup that includes the all-new 2016 Volt, 2016 Malibu Hybrid and Spark EV, Chevrolet will offer consumers more affordable, electrified vehicle options than any other major automotive brand – solidifying its position as the leader in electrification. "The Bolt EV truly embodies the ingenuity that is at the core of everything we do at Chevrolet," said Alan Batey, president of General Motors North America and head of Global Chevrolet. "The technologies and the engineering expertise behind the Bolt EV are tremendous examples of the kind of innovation we intend to offer our customers, across an array of products at a tremendous value – something only Chevrolet can deliver." Building on the electrification expertise established by the Volt, the Bolt EV is a game-changing, long-range electric vehicle.
