In view of tightened legislative demands concerning a clean environment with good air quality and global strategies to minimize CO2 emissions from individual mobility and transportation, further improvement of the thermo-dynamical behavior of modern Diesel engines is mandatory. The center of the operational behavior is despite highly sophisticated components in the exhaust aftertreatment system still the combustion system, defining the dominating base for the engine behavior in terms of efficiency and pollutant emissions. In order to design a superior starting point for the safe compliance with upcoming requirements, a fullyintegrated and aligned chain of advanced development tools and methodologies is absolutely mandatory to define the optimal description regarding fuel introduction and mixture formation to ensure a proper burning behavior for all kind of combustion modes. The usage of precise and validated frontloading processes offers the potential to determine the proper parameters already early in the conceptual phase and to reduce the loop of hardware iteration steps to finalize the nominal description of the engine hardware.
Within the paper, an overview of advanced computational and experimental tools and methodologies is presented in conjunction with upcoming technologies, offering the fast and direct path to a high-performing Diesel combustion system for future demands, covering main aspects like air utilization, EGR acceptance, and overall emission prediction – engine-out as well as tailpipe. The implemented examples describe the achievements, which were observed and validated by the usage of the process and tools on an advanced mono-cylinder engine, but further on also transferred to describe the potential of multi-cylinder application.

INGENIEURS DE L'AUTO SE DIGITALISE

 

 

La revue Ingénieurs de l’Auto est maintenant diffusée en print et on line. Une grande première pour la SIA avec ce numéro 865, disponible au format numérique.

Cette version digitale sera, à chaque numéro, réservée aux membres de la SIA abonnés.

Exceptionnellement pour ce premier numéro on line, et en lien avec la situation de confinement et de télétravail de beaucoup d’ingénieurs de notre industrie, la version digitale du numéro de Mai est accessible à tous.
