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.

10 best new car deals of November 2021

Sales of new cars, trucks and SUVs were drastically affected in 2020 due to the (still) ongoing coronavirus pandemic. The market started to show signs of recovery toward the end of last year before really coming on strong in the early months of 2021. Of course, then pandemic-related parts and worker shortages along with global shipping constraints started running amok and causing a great deal of pricing fluctuation and a limited supply of certain vehicles. Those problems (among other things) have led to record-high new-car transaction prices in the United States. The good news is that there are still plenty of great deals on new cars. Using data provided by TrueCar, we’ve compiled a list of some of the best automotive deals for November 2021. WeÂ’ve noted the original MSRP, the average transaction price, and the total savings in both dollars and as a percentage of the original sticker price. Basically, weÂ’ve done all the hard work for you! So now, all you need to do is compare deals, go on a few test drives, and maybe drive away in a great car (and an even better bargain).
