Book Synopsis

Finally! The authoritative manual on Bosch Fuel injection. This is the only book that fully explains all aspects of these Bosch systems: Motronic, L-Jetronic, LH-Jetronic, LH-Motronic, D-Jetronic, K-Jetronic, KE-Jetronic, and KE-Motronic. You will find specific information on the newest KE-Motronic and LH-Motronic systems that is not available from any other source. Author Charles Probst has worked directly with OEM fuel injection engineers, trainers and technicians from Bosch, BMW, Porsche, Mercedes, Volkswagen, Audi, and other manufacturers to produce technician training materials. Now his complete service and maintenance procedures, with expert advice and troubleshooting tips, are available to you. A sampling of areas covered in the book are listed below:
Theory: How each system works; How to troubleshoot problems and service each system; What tools and equipment are needed; How engine idle speed is controlled and can be adjusted; How to adjust air-fuel mixture; Understanding air measurement and fuel metering; How engine management systems adjust timing for gasoline octane and turbo boost.
Racing and high performance modifications: what works and what doesn't Probst clarifies advantages and operating principles of each Bosch system and explains how they work to deliver maximum engine efficiency. He also gives you high-performance tuning secrets that really work to deliver maximum engine efficiency. He also gives you high-performance tuning secrets that really work for street and racing applications, and tells you why some tricks like "fooling" the computer don't. With over 350 detailed illustrations and photos, this 224 page book is a must-have referencefor do-it-yourself mechanics, performance enthusiasts, and professional technicians who really want to understand Bosch systems.
