Trends in turbocharger applications
Published May 14, 2002 by Institution of Mechanical Engineers in United Kingdom
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?""
