Advanced direct injection combustion engine technologies and development Vol. 1 Gasoline and gas engines

Direct injection enables precise control of the fuel/air mixture so that engines can be tuned for improved power and fuel economy, but ongoing research challenges remain in improving the technology for commercial applications. As fuel prices escalate DI engines are expected to gain in popularity for automotiveapplications. This important book, in two volumes, reviews the science and technology of different types of DI combustion engines and their fuels. Volume 1deals with direct injection gasoline and CNG engines, including history and essential principles, approaches to improved fuel economy, design, optimisation, optical techniques and their application.
