CPT's auto exhaust gas energy recovery system

Controlled Power Technologies (CPT), best known for its VTES electric supercharger, is working on exhaust gas energy recovery.

CPT's auto exhaust gas energy recovery system

CPT’s Turbo-generator Integrated Gas Energy Recovery System (TIGERS) uses the same switched reluctance technology as its production-ready VTES electric supercharging and SpeedStart stop-start systems.

The TIGERs concept has been around for years now. Never a product actually sold though.

CPT estimates it will take five years to bring TIGERS to market.
Thats just ridiculous. Its a relatively simple product.

I love the idea, I just think the development time to launch is a joke.

what is it exactly, a turbo married to an alternator?? The lack of details is striking.

Exactly what i was thinking....with a reduction gear or a clutch that locked the rpm of the alternator at its most efficient point....

It still takes power to turn the alternator though.
