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 Silverado WT gets its own murdered-out trim pack

Media days for the 2015 Chicago Auto Show ended last week, but that hasn't stopped Chevrolet from adding just one more thing. The Bowtie brand showed off three new trim packages for its trucks in the Windy City – the Colorado GearOn and the Silverado Midnight and Custom – but protests from consumers over the price of these equipment packs has led the company to release a new trim group for its most affordable fullsizer, the Silverado WT. The $1,595 Black Out pack will be available on both the regular- and double-cab Silverado WT and offers a few simple, stylistic upgrades. Five-spoke, 20-inch black wheels are the headlining item, although Chevy will also include "deep tinted glass" and black bowtie badges both fore and aft. Available only in black (the company even paraphrases old Mr. Ford in its press release), the new package adds just enough to class up the otherwise dreary looking Work Truck. Chevy has only released one image for the time being, available up top. Dealers, meanwhile, are currently taking orders. Check below for the brief press release. Chevrolet Silverado Work Trucks Get Blacked Out DETROIT – Chevrolet is adding a $1,595 Black Out package for regular- and double-cab 2015 Silverado 1500 WT models. It includes 20" black painted aluminum wheels, P275/55R20 all-season blackwall tires, deep tinted glass and black bowties. Prices start at $28,895. The package is available for order now, and customers can have any color they want, as long as it is black. Editors' Note: Manufacturer's Suggested Retail Price excludes tax, title, license, dealer fees and optional equipment. Includes dealer freight charges and option package discounts. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.8 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature engaging performance, design that makes the heart beat, passive & active safety features and easy-to-use technology, all at a value.
