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.

Car Club USA: Louisiana Mudfest

There's nothing quite like mudding. Big tires, huge power, and crazy-wild gearheads that like to throw down on a mud pit almost as much as a thirty rack of Coors. In the latest, and some might argue greatest yet episode of Car Club USA, we head to Louisiana to throw some dirt at Mudfest. As Louisiana's one and only Mouth of the South puts it, "If you don't mud ride... go to Texas I guess." Joining The Mouth and friendly rivals The Most Hated Mud Sluts, we dive in. Beyond the obvious V8 blasting and tractor-tire spinning, those who know best describe Mudfest as, "Good cooking, good friends, good fun, and a lot of partying." It's a motorsport spectacle unlike any you're likely to find up North or out West, though no less impressive to behold. Follow along with the fun, the impromptu drag racing, the trash talking, and the mechanical madness. And find out why, at Mudfest, "if we don't tear it up, we ain't done it right." Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures. From Main Street cruises to off-road trails, catch all the latest car club activity on Autoblog. Chevrolet Ford Jeep RAM Truck Off-Road Vehicles Car Club USA Videos autoblog black

Recharge Wrap-up: BMW cars to share i tech, Jordan to build solar EV charging network

Jordan is looking to promote EVs and build a solar charging network. The country is waiving import tariffs on electric cars, and is spending $120 million on solar chargers. It plans to build 3,000 charging stations, along with 30 MW of solar power. Some chargers will be powered by solar canopies, while others will get electricity from nearby solar farms. Jordan's solar plan should also help to lessen the amount of energy it needs to import from nearby countries. Read more from Navigant Research, or at Green Car Reports. BMW's mainstream cars will benefit from technology borrowed from the i3 and i8, according to BMW sales head Ian Robertson. In an interview with Automotive News, Robertson said that next-generation cars will use carbon fiber more extensively, and that more cars will get plug-in technology. He said that about half of i3 buyers opt for the range extender and added that it is incorrect to refer to a range-extended electric vehicle as a plug-in hybrid. Read more at Automotive News. The ethanol market should remain healthy despite falling oil prices. While cheap oil could drive down ethanol prices, demand still remains due to the federal biofuels standard. Additionally, ethanol producers may find it cheaper to ship their products as domestic oil production drops and railroad shipping opens up. Ethanol byproducts like distillers grains continue to sell, and foreign demand continues as other countries impose their own renewable fuel standards. Read more at Yahoo News. Via Motors will launch the production of an electric Chevrolet Silverado. The company will convert the pickups into range-extended EVs at its assembly line in Mexico, near GM's Silverado plant. Via has the capacity to produce 10,000 vehicles per year at its Mexico facility. Via Motors Chairman (and former GM Vice Chairman during the early days of the Chevrolet Volt project) Bob Lutz wants to help make EVs mainstream in America, and believes that requires electrifying pickups and SUVs.
