@dickdelfonzi: A turbocharger recovers part of the energy leaving in the exhaust. Hot exhaust gas spins the turbine; a shared shaft spins a compressor on the intake side. That compressor raises intake pressure, packing more air into the cylinders so more fuel can burn—and the engine can make more power from the same displacement. Which should we open next: a wastegate or a supercharger? #Turbocharger #EngineEngineering #HowItWorks #HiddenEngineering
