For decades, scientists and engineers have been working to increase the efficiency of internal combustion engines. For spark-ignition engines, two technical questions in particular are always in focus: 1. How can the air/fuel mixture be optimally ignited under all possible conditions? 2. How can undesirable but recurrent early and self-ignitions in the air/fuel mixture be avoided? Against the background of the considerable efficiency increases currently being sought in the context of developments and the introduction of new fuels, such as hydrogen, methanol, ammonia and other hydrogen derivatives as well as biofuels, these questions are more in the focus than ever. In order to provide a perfect exchange platform for the community of combustion process and system developers from research and development, IAV has organized this combined conference, chaired by Marc Sens. The proceedings presented here represent the collection of all the topics presented at the event and are thus intended to serve as an inspiration and pool of ideas for all interested parties.

Many of the hundreds of thousands of Syrians who immigrated to the US beginning in the 1870s worked as peddlers. Men were able to transgress Syrian norms related to marriage practices while they were traveling, while Syrian women accessed more economic autonomy though their participation in peddling networks. In Possible Histories, Charlotte Karem Albrecht explores this peddling economy of the late nineteenth and early twentieth centuries as a site for revealing how dominant ideas about sexuality are imbricated in Arab American racial histories. Karem Albrecht marshals a queer affective approach to community and family history to show how Syrian immigrant peddlers and their interdependent networks of labor and care appeared in interconnected discourses of modernity, sexuality, gender, class, and race. Possible Histories conceptualizes this profession, and its place in narratives of Arab American history, as a "queer ecology" of laboring practices, intimacies, and knowledge production. This book ultimately proposes a new understanding of the long arm of Arab American history that puts sexuality and gender at the heart of ways of navigating US racial systems.
