    BMW wants to patent electric Turbo

    Turbochargers are a popular technology in the automotive world as of late. It allows rather low displacement engines to have relatively high power outputs, while also managing to return fairly good fuel consumption figures (on paper).

    Despite the technology being decades old, some of its drawbacks could still be improved upon. One of these issues is the well-known problem of turbo size. A smaller turbine spools up quicky but runs out of steam at higher revs while a bigger turbine offers enough power at high revs but often is too slow at lower revs which results in turbo lag.

    BMW has now patented its own idea on how to address these issues, and it involves the use of an often rumored "electric turbocharger".

    Bimmerboost reported before that BMW has considered (or may still be considering) the use of an electric turbocharger as part of a potential tri-turbo 6-cylinder engine for the next generation F80 M3 (the latest rumors lean towards a bi-turbo V6 as the new M3's powerplant). While we still don't know if the next gen M3 will be powered by an engine with an electric turbocharger, we do now know how such an electric turbocharger would be implemented, courtesy of a patent application BMW submittted to the German patent office.

    According to BMW’s patent application, this invention makes for a great engine response, particularly during the transition from idling to load. It also renders a wastegate needless and adds efficiency.

    Well, I copied it, a bit harsh to not state the source...

    You did the right thing. I didn't post it because I will never post any of their stuff.
