Bio-ethanol engine for advanced urban transport by light commercial vehicle& heavy duty

Objective of the BEAUTY project was to build, in a crash programme of 2 years, engine solutions based on the three technology ways able to meet ambitious targets in terms of: future emission limits (Euro 6); fuel conversion efficiency (at least 10% higher than that of a today SI engine running on equivalent bioethanol blends); cold startability down to - 15 °C of ambient temperature. Starting from existing powertrains, the engine systems (including after-treatment), components and materials were adapted and optimised. The most promising route for maximising the benefits in terms of local- and global-emissions were identified. The three technology ways were compared in terms of costs and time to market, taking into account the type of fuel that can be used in the captive fleet.
