Water injection offers high potential to meet the requirement for stoichiometric operation throughout the engine map at consistently high power density. In this article, FEV Europe demonstrates performance limits of direct and port water injection for boundary conditions of large scale production engine concepts and presents possibilities for efficiency enhancements in combination with water recovery.

Starting Point

The compliance with the emissions limits under RDE conditions is a major challenge in the development process of modern gasoline engines - not least because of the diversity of the driving profiles and their sensitivity to the emissions. While nitrogen oxide (NOx) and particle emissions are limited with conformity factors under RDE conditions, carbon monoxide (CO) emissions are currently only under observation. However, an extension of the conformity factors for CO emissions is generally expected for the Euro 7 legislation. In this case, mixture enrichment for component...

Notes

Thanks

Parts of this project with regard to exhaust gas condensation were carried out in cooperation with Hanon Systems Deutschland GmbH. We are very grateful for the collaboration and the support in this area. Further, we would like to thank Lukas Weiner for supporting this research within the scope of his activities at the Institute for Combustion Engines of the RWTH Aachen University.
