CO2 Emission Efficient Hybrid Engine wins Watt d’Or 2014

CO2 Emission Efficient Hybrid Engine wins Watt d’Or 2014

The research group at ETH Zurich, led by Prof. Lino Guzella, has won the Watt d’Or 2014 energy prize for development of a natural gas-diesel hybrid engine. The innovative combustion engine system emits up to half as much CO2 as conventional engines and with the same performance. This is the third time that Guzzella’s group won a Watt d’Or.

The savings of this new engine are impressive; the natural gas and diesel hybrid engine developed at the Institute for Dynamic Systems and Control at ETH Zurich undercuts the current CO2 emission limits by a third to a half while maintaining the same performance. Its equivalent fuel consumption is less than 2.4 litres per 100 km.

The Federal Office of Energy’s Watt d’Or award, which is now in its eight year, selects projects and initiatives that pave the way for a sustainable and energy-efficient future. Researchers Christopher Onder, Tobias Ott, Florian Zurbriggen and Lino Guzzella, Professor of Thermotronics and Rector of ETH Zurich, won in the category “energy-efficient mobility” because they demonstrated a highly efficient engine as well as a marketable solution.
