Electric Turbo Charger

Okay so where does the electrical power to run all the electrical gear on a originally come from and what is the overall beginning to end efficiency?

BTW turbo lag is only a problem if the person/people designing the system didn't match the turbo to the engine characteristics properly for the conditions involved.

It must have some good qualities or they wouldn't be spending the money.

Will they be around in five years????????????????????????????

It's all forced induction, be it turbocharging, supercharging, or whatever.

Just an AIR version of stuffing "...five pounds of BS into a three pound bag..."

I had always perceived the heat issues for exhaust driven turbos to be a weak point. Will the electric versions still require critical bearing lubrcation and seal systems? Will this reduction in heat enhance inter cooling?

had you bothered to read the link you would have seen the entire concept is to spool the shaft quickly to eliminate lag while waiting FOR RPM to build. once at speed its a normal turbo, it has nothing to do with the heat of compression.

Turbo-lag is a thing of the past with newer turbos and the ability to change the pitch of the turbo's vanes.

I did and I am talking about exauhst gas temperatures. Not compression temperatures. The clarity of concept appears to be lacking for someone else.

Something old is new again. Like most things this was done a long time ago and could not be used. Kind of like the Tucker head lamp. But, granted they tried front wheel driven cars back then as well and it did take off with newer materials and engineering design capacity's of today.

The hybrid turbo technology being employed in F1 for 2014 is of course far more advanced and complex, making for the most energy efficient engines in the world. Not only does the turbo get extra drive from electrical energy, it also generates electrical energy for storage and reuse, and by way of doing that eliminates the need for a waste gate. Combined with kinetic energy recovery and drives they're making almost 800hp out of 1.6 liter V6's and meeting incredibly strict fuel consumption and load limits.

The auto tech that has my attention right now is Nanoflowcell AG. Probably a ways off for wide spread application, but likely the eventual future.

Im very interested in this. Could it be applied to air cooled vw engines to boost MPG...

Forced induction does not increase MPG, it reduces it at the expense of horse power gains.

To actually gain significant MPG you need to go to direct fuel injection into the cylinders; a technology that is just starting to become more popular much like fuel injection phased out carburetors.

However, forced induction does allow you to reduce the displacement of an engine to achieve similar power produced by a normally aspirated engine of larger displacement. Under those conditions where boost is very low or off (i.e., highway cruising) you achieve better fuel economy with a smaller displacement engine.

In your case with the VW engine, forced induction would only increase the engine's power output and lower both the fuel economy of the engine and the engine life.

Another thing with air cooled engines is that they are less efficient than their water cooled counterparts because water cooling allows the engine to operate at its peak temperature environment for maximum efficiency, whereas air cooling yields a much wider operating temperature range due to environmental conditions.

Ah-h-h-h, but 'controlled' forced-induction allows the back-n-forth transition between power gains and fuel economy gains...under either driver- (poor) or ECM-control(better).

Again, you must replace the engine with a smaller engine to get this savings.

Slapping a turbocharger or any forced induction accessory on the same engine guarantees you will get lower fuel economy than it produced before the conversion, which was the question asked about the VW engine.

Kinda reminds me of this.

I remember a certain RV powerd by a torbocharged Renault engine, for what reason, was never clear.
