The BOSCH handbook series on different automotive technologies has become one of the most definitive sets of reference books that automotive engineers have at their disposal. Starting with a brief review of the beginnings of automotive history, this book discusses the basics relating to the method of operation of gasoline-engine control systems. The descriptions of cylinder-charge control systems, fuel-injection systems (in-take manifold and gasoline direct injection), and ignition systems provide a comprehensive, firsthand overview of the control mechanisms indispensable for operating a modern gasoline engine. The practical implementation of engine management and control is described by the examples of various Motronic engine-management systems and of the control and regulation functions integrated in this particular management system. The 3 rd edition offers new or completely revised chapters in the following areas - High pressure pumps for direct gasoline injection; Mixture formation for manifold injection; Gasoline engines fuelled by natural gas; Catalytic exhaust-gas treatment; Diagnostics. A key chapter looks at emission control legislation and provides an insight into the complexity of the statutory provisions.
