Inlet port flow characteristics are critical in determining the overall performance of diesel
combustion systems. The relationship between inlet port geometry and performance has long
been a subject of interest to many researchers, although as yet a comprehensive understanding
remains elusive. The ongoing need to provide advanced powertrain design solutions in order to
meet increasingly stringent emissions legislation, whilst meeting customer expectations and
minimising engineering costs, has driven the development of new approaches to engine design.
In particular, the fundamental advantages of multivalve technology, coupled with rapidly
improving fuel delivery systems has placed new requirements on inlet port performance
characteristics. Statistical methods and knowledge-based design are emerging as potentially
powerful tools in this field of research, supported by rapid developments in computing power.
