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.

GM to invest $150 million in Flint to boost heavy-duty pickup production

FLINT, Mich. — General Motors President Mark Reuss said on Wednesday that the automaker is investing about $150 million at its Flint Assembly plant in Michigan to boost production of heavy duty trucks by another 40,000 vehicles a year. Reuss announced the investment at the Flint truck assembly plant wearing a United Auto Workers pin. The Detroit automaker had announced back in February it was adding 1,000 jobs in Flint to build a new generation of heavy-duty pickup trucks. GM did not say that the latest investment would add more jobs at the plant, but Reuss said there could be opportunities to add workers as the launch of the automaker's new trucks progresses. GM has been under pressure from President Donald Trump and lawmakers of both parties to add jobs in the United States after it said last November it would idle the Chevy Cruze assembly plant in Lordstown, Ohio, and likewise had no new products for three other U.S. manufacturing plants. The Flint investment will include upgrades to the plant's conveyors and other new tooling, and will be completed in the first half of 2020. GM has invested more than $1.6 billion in the plant since 2013. Last month, GM said it would invest $24 million to increase truck production at its assembly plant in Fort Wayne, Indiana, which makes Chevrolet Silverado and GMC Sierra models. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM's Chevrolet and GMC brands have long trailed Ford's F-series heavy duty trucks in the lucrative segment. The new Chevrolet and GMC heavy duty trucks have been re-engineered to tow heavier trailers, and keep pace in what has become an arms race among the Detroit Three automakers to claim superior torque and towing capability.
