Direct injection enables precise control of the fuel/air mixture so that engines can be tuned for improved power and fuel economy. This must be balanced against increased equipment costs and emissions, presenting ongoing research challenges in improving the technology for commercial applications. This important book reviews the science and technology of different types of DI combustion engines and their fuels. Five main sections provide an overview of the state of the art, covering gasoline DI engines; both light-duty and heavy-duty DI diesel engines; alternative fuels and aftertreatment devices; and advanced modeling and experimental techniques.
