EVE® - Energy Via Exhaust

Technology presenting the best
cost/efficiency ratio on the market

Only one third of the fuel introduced into a combustion engine is used to move the vehicle. The rest is lost in the form of heat via the cooling jacket and exhaust pipes.

Disruptive technology is the only way to remedy this energy consuming deadlock. Exoès developed EVE® (Energy Via Exhaust), convinced that heat recovery is the ultimate lever for improving combustion engine efficiency.



Protected by more than 10 patents

EVE® - Energy Via Exhaust - is the key component of the Rankine system.
It perfectly fits the specifications of vehicle OEMs and Tier Ones.
