Regenerative braking? - Page 2 - Toyota Yaris Forums

Okay, wait, I'm lost....

Let's assume that somehow you DID get the compressor to run backwards.

How is that supposed to help anything? And how the heck does it tie into the braking? How do you propose the energy of momentum be captured and returned to the AC compressor?

I have no idea what we're talking about. I get it for electric vehicles, but I can't imagine anything else...?

He wants to use an engine driven air compressor to stock pile energy captured through braking / general turning of the engine, to be released via reversing the compressor, in effect making it an air driven motor, upon acceleration.

My take on this is that most of the energy captured by this setup will be lost to heat, but that's just me.

I think Bail Out said something quite good. Use batteries instead of air pressure. Replace the compressor with a DC motor that charges a high voltage battery(s). On takeoff the process would reverse, the battery would power the motor to assist acceleration. I don't know how much torque a belt could assist the engine with though. Maybe a belt and pully with teeth or something. Food for thought anyway.

Don't they already do that? They call it a Prius.
