Enter Stage Two: GM Patents New Two-Stage Twin-Turbo Tech
C & D

July 6, 2016 by Greg Fink


General Motors...has filed a patent with the United States Patent and Trademark Office that may signal the companyís next steps in turbocharging technology...
...outlines a potential means of taking maximum advantage of the energy available in the exhaust stream with a two-stage, twin-turbo setup using turbochargers of different sizes.

While this basic premise isnít new, GMís proposed means of managing the pair is. Relying on an ECU that is constantly measuring engine speed and load, GMís patent suggests equipping two-stage twin-turbocharged engines with a pair of butterfly valves operated by an electronic actuator. These valves are used to control exhaust flow to the two turbos. Both valves are mounted on a common shaft so that when the actuator closes one valve, it simultaneously opens the other (and vice versa). Such a system allows the smaller, quicker-spooling turbo to operate at lower engine speeds and the bigger turbo to come online during events that call for higher engine speeds. In short, it works much like any other two-stage twin-turbocharged engine...

And GM's supporters accuse Ford of being far too complex with engine design..
