Will BMW s electric turbocharger end lag?

Yes, apparently is a replacement for displacement. If recently-uncovered filings are correct, BMW is working on an turbocharger that combines a turbo with an electric If it works, the system will let engines produce more while performing virtually

Turbochargers have long a way to employ lost energy, in the of fast-moving exhaust gases, to more power by stuffing air into the cylinders to burn fuel. The traditional trade-off has between smaller turbos spool up quickly, providing transient response and preventing lag, and larger ones can jam more air down an engine’s at higher RPMs. BMW’s twin-turbo setup offsets the by using both types. But is the planning to tie its turbos into the electricals of its Efficientdynamics gear?

The answer is perhaps.

F30post had reported that the company was a tri-turbo system for the next-gen M3. The new filings may have something to do such a system, but we don’t for sure. We do know that companies like Borg and Garrett have been on similar electrically-assisted turbocharger for about a decade.

To be fair, electric turbocharger is a bit of a one that might confuse into thinking BMW’s into the world of cheap superchargers, long a bane of the BMW’s system is apparently a turbocharger, which combines a with an electric motor-generator.

The turbine and compressor on separate axles that can be by a clutch — with the electric constantly running in the middle. full-throttle starts, the electric runs the compressor in an instant-on virtually eliminating the time it normally take the exhaust to spin up a traditional turbine. the turbine’s up to speed, the clutch the turbine shaft to run in conjunction the electric motor.

Naturally, all of this switchery at ridiculously high RPMs.

Now the cool part. Rather using a wastegate to hold the speed of the turbine, the electric kicks into generate The resulting electrical current back to the battery (or, to a supercapacitor), while the additional from the generator regulates speed.

Naturally, all of this will be by copious electronics, the likes of aren’t clear from the

There’s no information on the vehicles in BMW might use such a system, but the company’s push to up the degree of gear in its engines, something this is a logical next [See F30post for more.]
