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.

Europeans ask Chevy to bring Volt back to Europe

A group of French fans is asking for a jolt of support from General Motors to get the 2016 Chevrolet Volt across the pond. The Association Amperistes et Amis des Vehicules Rechargeables is running a Change.org petition that currently has 383 signatures out of a goal of 500. While the attempt is admirable, it's probably going to take a lot more than several hundred people for the model to make a return to the continent after the poor showing of the Opel Ampera – first-gen Volt's European cousin. The group's major argument for bringing a version of the second-gen Volt to Europe is that consumers need "an intermediate choice between expensive or range-limited pure electric cars and plug-in hybrids with a miserable electric range." Furthermore, such a vehicle would prod the competition to produce similarly efficient electrified models. They also lavish praise on the abilities of the Ampera for its long EV driving range. The supporters aren't entirely kind to GM in the petition, though, and claim the company excluded the original car from marketing efforts there. The Ampera actually enjoyed a strong European launch with more orders than initially expected and briefly topped the best-sellers list among EVs there. It was even named 2012 European Car of the Year. Those halcyon days didn't last long, and by 2014 sales fell off to a trickle. The waning reception caused GM's decision not to introduce a version of the new 2016 Volt there or in Australia. Related Video:
