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's Android Auto update will reach cars in March

Buying a new Chevy with the hopes of using Android Auto during your daily commute? You'll have to sit tight for a while before that dream becomes reality. The carmaker announced that an Android Auto software update will only reach its 2016 model-year vehicles next March, starting with those that have 8-inch MyLink touchscreen systems. That's going to be a long half-year wait if you're eager to get Google Maps directions through the center stack. The good news? Chevy is promising that all vehicles with 7- and 8-inch MyLink displays (ranging from the Spark to the Corvette) will eventually have Android Auto, so you won't have to drive one of the brand's swankier machines to get a smartphone-powered infotainment deck. This article by Jon Fingas originally ran on Engadget, the definitive guide to this connected life. Related Video:

GM invests $175 million in Chevy Camaro factory

General Motors just keeps rolling out portions of its $5.4-billion plan for factory upgrades over the next three years. In the latest announcement, the automotive giant is putting $175 million into the Lansing Grand River Assembly Plant for improvements to build the 2016 Chevrolet Camaro. The investment brings new equipment to the plant to build the pony car. An upgrade is needed to support Camaro-specific colors like Summit White, Bright Yellow, and Red Hot, and the factory is also getting two robotic framers. A second shift of 500 workers is resuming in Lansing later this summer to produce the model, as well. So far, GM has announced allocations for $2.8 billion of the $5.4 billion in upgrades. The investments include $1.2 billion to improve pickup production, $439 million for a paint shop for the Corvette, and more new equipment at other plants too. Lansing Grand River Plant Tools Up for 2016 Camaro $175 million investment enables production of lighter, more powerful model 2015-05-28 LANSING, Mich. – A $175 million investment for new tooling and equipment for the sixth-generation Chevrolet Camaro, and the return of hundreds of workers to build America's best-selling performance car for the last five years, was announced today. The facility improvements include three new paint systems for Camaro-specific colors: Summit White, Bright Yellow, and Red Hot. The investment also includes installation of two robotic framers, which allow better dimensional control to provide a more precise drive experience. The Lansing Grand River Assembly Plant will resume a second shift of 500 jobs in late summer. The all-new Chevrolet Camaro was introduced on Detroit's Belle Isle on May 16. The current generation Camaro has been America's favorite performance car for five consecutive years, attracting both long-term Camaro fans and new buyers to Chevrolet. To improve on that success, the sixth-generation Camaro elevates every aspect of Camaro with a suite of new technologies, even higher levels of performance and fuel economy, and a leaner, more athletic design. "I may be the luckiest mayor in America today," said Lansing Mayor Virg Bernero. "Gearing up for full-scale production of the legendary Chevy Camaro is a new high point in the more than two decades of extraordinary partnership between the City of Lansing, General Motors and the UAW.
