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.
Over 60% efficiency
Exoès developed innovative, inlet and outlet patented systems. Internal tests on our products confirm:
- An effective isentropic efficiency of over 60%, meaning one of the most efficient yields in the market
- A constant yield throughout the whole engine map
The best cost/efficiency ratio on the market
EVE® is set up to be mass-produced:
- Weight: < 15kg
- Size: < D200 x L200 mm
- Design: several ancillary components are integrated into the expander
- Materials: from automotive sector
Tested by major OEMs and Tier Ones
EVE® has been tested:
- On-road, in real driving conditions: in a HGV Renault Trucks (Volvo group)
- On our test benches: > 2,000 hours of tests, > 20,000 starts/stops
- On our client benches (OEMs, Tier Ones) or those of our academic partners always with positive test results
