Bosch was founded in Stuttgart, Germany, in 1886 by Robert Bosch as a workshop for precision mechanics and electrical engineering. The company became one of the world's largest automotive suppliers and a pioneer of vehicle electrics, developing magneto ignition, spark plugs and the electrical and electronic systems that cars and trucks depend on. More than a century later, Bosch remains one of the world's largest automotive suppliers, and its name appears on engine components fitted by manufacturers on every continent.

Bosch is best known in the engine world for fuel and engine-management technology. It introduced diesel injection pumps in the 1920s, developed the gasoline injection systems that transformed performance cars in the 1960s and 1970s, and later produced electronic engine management, common-rail diesel injection and direct-injection petrol systems used by manufacturers across the globe. Its injection and ignition components have been fitted to countless engines over nearly a century.

Bosch workshop documentation explains the construction, operation and service of the fuel systems on this page: injection pumps and injectors, sensors and actuators, electronic control units and their programming, and the complete wiring and circuit diagrams that connect them. It includes test procedures, pressure and timing specifications, torque data, fault codes, diagnostic routines and the special tools needed for calibration and testing.

These manuals are indispensable for fuel-injection specialists, independent garages, and technicians who diagnose and repair Bosch-equipped engines and need precise manufacturer data to set up injection and ignition systems correctly.
