Evolutionary design of internal combustion engines: An innovative methodology has been developed to design engine combustion chambers to fulfill european legislation on automotive emission

摘要

The more and more restrictive legislations on air pollution and the need of dramatically reducing the development time of new engines have introduced a new challenge in the design of internal combustion engines. In this scenario, the shape of the combustion chamber plays a key role, since strongly affects the combustion process and emissions mechanisms of formation. Designers have to abandon the traditional "rule of thumb" in the definition of the combustion chamber shape and search for innovative solutions.
