Book 2: Petrol Engine Actuators
The completely revised and extended new edition of Volume 2 "Petrol Engine Actuators" from the series "Signals in Images" has been published.
The 2nd Edition comprises 100 pages covering all Petrol Engine Actuators. The contents describe reference and erroneous signals, options for connecting-up test equipment, the respective vehicles and systems, as well as the appropriate reference values for the following components:

- lambda probes
- injector valves
- injectors for direct-injection systems
- fuel-pressure regulators direct-injection systems
- various idle-adjusters for different systems
- camshaft adjustment BMW, Ford, Fiat
- secondary-air injection
- electric coolant pumps
- electrical fuel pumps
- magnetic valves for oil pressure control
- bypass valve turbocharged engines
- exhaust gas recirculation
- injection systems for all vehicle manufacturers
- etc.
Volume 2 "Petrol Engine Actuators" complements Volume 1 "Petrol Engine Sensors", which deals extensively with sensor signals. Furthermore, this book is part of the multi-volume series "Signals in Images".
This manual is a good source of help in supporting day-to-day error diagnosis. It is ideal for training centers, apprentices and advanced training. For garages and workshops, interested in keeping up-to-date, this manual is a must have. With its contents and approach, it complements other, already available reference books.
The manual is an excellent companion in error diagnosis. The contents describe, in short, the functionality of individual actuators using drawings and connection-diagrams and provide typical reference values for individual components.
