New Publication – Fuels for Efficiency / Advanced Fuels for Advanced Engines

The trend of vehicle electrification might dominate the global vehicle industry within a foreseeable future; however, a seamless transition needs to be addressed. Internal Combustion Engine technology has been developed for almost 100 years. Most automotive engineers are aware of the need to achieve maximum thermal efficiency while keeping emissions low, but more focus is needed to enable the highest efficiency of advanced engines in combination with new advanced fuels.

This report is the result of a combined effort of IEA AMF Annex 52 and IEA Bioenergy Task 39. The work consisted of five parts:

1. Survey on Advanced Fuels for Advanced Engines (Task 39): Diversity of fuels will increase further. Next to user friendly drop-in fuels that can be implemented using the existing infrastructure, other advanced fuels will be developed or introduced in the market. These fuels can be produced on the basis of biomass (so called biomass-to-x fuels), but also on renewable electricity together with a carbon source (so called power-to-x fuels). Furthermore, to achieve the mutual benefit of engine fuel interaction, new engines should be flexible for a wide range of fuels fulfilling the requirements regarding CO_2-eq emissions as well as local emissions like NO_x, particles etc.
2. Performance Evaluation of Chemical Friction Modifiers for Diesel and Gasoline Fuels
3. Waste Heat Recovery / Fuel Reforming by Thermo-chemical Recuperation (TCR)
4. Performance Assessment of Various Paraffinic Diesel Fuels in non-road diesel engines
5. Opportunity for Enhancing Fuel Efficiency by Ethanol Blended Gasoline Fuels
