This book presents and evaluates the latest techniques for measuring, evaluating and controlling NOx and CO2 emissions from marine diesel engines. The book also provides a reference guide for the effective selection and implementation of these techniques. It discusses innovative methods for acquiring and estimating the required engine-related parameters in a more accurate manner than with conventional approaches, and provides photos and illustrations of real-life examples to elucidate the book’s content. Chapters examine topics including the legislative framework of NOx emissions; marine CO2 emissions and global warming; simple and direct on-board emission measurement techniques; the determination of engine operation parameters; the estimation of NOx emissions through modeling; and NOx reduction techniques. An invaluable resource for marine and mechanical engineers, engine manufacturers and service engineers, this book is also intended for marine industry professionals and manufacturers of exhaust gas measurement equipment.
