The book includes the papers presented at the conference discussing approaches to prevent or reliably control knocking and other irregular combustion events. The majority of today’s highly efficient gasoline engines utilize downsizing. High mean pressures produce increased knocking, which frequently results in a reduction in the compression ratio at high specific powers. Beyond this, the phenomenon of pre-ignition has been linked to the rise in specific power in gasoline engines for many years. Charge-diluted concepts with high compression cause extreme knocking, potentially leading to catastrophic failure. The introduction of RDE legislation this year will further grow the requirements for combustion process development, as residual gas scavenging and enrichment to improve the knock limit will be legally restricted despite no relaxation of the need to reach the main center of heat release as early as possible. New solutions in thermodynamics and control engineering are urgently needed to further increase the efficiency of gasoline engines.

This book was released on 2022-10-17. International Conference on Ignition Systems for Gasoline Engines – International Conference on Knocking in Gasoline Engines available in PDF, EPUB and Kindle. 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.

The European Commission is planning to limit emissions under real driving conditions up to high engine loads. RDE (real driving emissions) legislation demands the complete conversion of exhaust gases in the catalytic converter which can only be achieved for spark-ignition engines at lambda=1. High exhaust gas temperatures resulting from late centers of heat release caused by knock can then no longer be limited by mixture enrichment. In addition, higher mean effective pressures are needed to improve the efficiency of SI engines. A strong tendency to knock during stoichiometric combustion in conjunction with high mean effective pressure places exacting demands on the SI engine combustion process. The focus of engine development consequently remains on reducing knock and on avoiding irregular combustion events. In particular, phenomena such as pre-ignition, which is typically observed in downsizing concepts, or extreme knock of the type frequently occurring in highcompression lean-burn concepts, are immense challenges to developers.
