Abstract
This paper explores the demands on modern turbocharger
technology and the response of the manufacturer to the needs of the
market. It goes on to expand on the technologies used to meet
demands and how these technologies are also being applied
pro-actively, to allow medium-speed diesel engine manufacturers to
accelerate progress in engine ratings. Topics covered include: -
Increasing turbocharger efficiency through improved aerodynamic
design methods; - Optimization of aerodynamics and frame sizes to
offer ""best fit"" solutions; - Introduction of
higher pressure ratio turbocharger equipment; - Design to meet
customer requirements for applications and service requirements in
the field.
The paper reviews the performance of current turbocharger
products and describes how field experience is now being built on
to provide an expanded range of turbocharger equipment to meet more
specific engine matching requirements. Further 8 Series
developments are described and the technologies being used to
provide higher-pressure ratio and higher efficiency turbochargers.
The implications of pressure ratio increase are discussed and how
this continuing trend impacts both on the basic turbocharger
aerodynamic design and the requirements for associated hardware
features.
To conclude, the paper looks further into the future to provide
a vision of the possibilities for future turbocharger equipment and
the challenges yet to be faced by the industry. Increasing demands
of legislation are discussed and how these may impact on designs
and turbocharging options. The paper finally poses the question,
""Which way will the Industry develop in the coming
Decade?""
