"This is an impressive coverage of the latest technology of component design for both diesel and petrol FI engines in compliance with the latest emission legislations. The book provides an insight into the technology, and readers will benefit from discussions on the overall future trend of fuel systems."--Materials World, March 2014Reseña del editor:
Summary: This book presents the papers from the latest conference in this successful series on fuel injection systems for internal combustion engines. It is vital for the automotive industry to continue to meet the demands of the modern environmental agenda. In order to excel, manufacturers must research and develop fuel systems that guarantee the best engine performance, ensuring minimal emissions and maximum profit. The papers from this unique conference focus on the latest technology for state-of-the-art system design, characterisation, measurement, and modelling, addressing all technological aspects of diesel and gasoline fuel injection systems. Topics range from fundamental fuel spray theory, component design, to effects on engine performance, fuel economy and emissions. The Institution of Mechanical Engineers (IMechE) is one of the leading professional engineering institutions in the world.
