NoWaste

The re-use of the waste heat (60% of the combustion energy) could allow to increase in overall vehicle energy of up to the 15%, this benefit could be higher in case of hybrid powertrain where generated electric energy could be used when more convenient. NoWaste aims to demonstrate the feasibility of such a system based on thermodynamic cycle (e.g. Rankine).

The Project key points are:

• definition of a reference mission
• selection of the most appropriate architecture
• heat rejection system minimizing the cooling drag and the impact on the front-  end
• heat exchangers development to maximize the heat recuperation efficiency
• integration with the exhaust system
• validation of the developed system at first on a test rig and then on vehicle demonstrator based on a hybrid powertrain
• system benefit evaluation to various heavy duty powertrains thanks to a model approach

Target Performance:

• Fuel Economy:           > -12%
• Cost (for the OEM):   < 4500 Euro/system
• Weight:                     < 150 kg
