Opis

The papers collected in this volume address all aspects related to thermofluiddynamic processes in diesel engines, from basic studies aiming to obtain a better understanding of the physical processes underlying diesel engine operation, to the real day-to-day problems associated with engine development. The topics covered comprise: Air management, injection systems, spray development and air interaction, combustion and pollutant formation, emission control strategies, and new concepts.
