computerized engine controls ninth edition pdf
The application of the microprocessor with its related components, circuits, and systems has made automotive technology exciting, fast paced, and more complicated. Technological advancements continue to add complexity to the modern automobile at record-setting rates and show no signs of slowing down. Ultimately, the technology requires that entry-level automotive service technicians must be well trained in the principles of automotive technology and must continue to upgrade their training throughout their careers.
Those who do this will find the task challenging, but achievable and rewarding. This text was written in response to a widely recognized need within the industry: to help students and technicians get a commanding grasp of how computerized engine control systems operate and how to diagnose problems associated with them. The student/technician who studies this text will soon come to realize that no single component or circuit on any given computerized engine control system, other than the computer itself, is complicated.
Computerized Engine Controls is written with the assumption that the reader is familiar with the basic principles of traditional engine, electrical system, and fuel system operation. Although everything here is within the grasp of a good technician, this textbook is not a beginner’s book.
Computerized Engine Controls contains eleven generic chapters (Chapters 1 through 9, 17, 18) and seven system-specific chapters (Chapters 10 through 16). Emphasis should be placed on the generic chapters due to the standardization that OBD II brought to our vehicles back in 1996. While there are differences between manufacturers, the reality is that there are more similarities than differences.
Even prior to OBD II implementation, the input and output sides of the various computer systems were more similar than different. OBD II standards then standardized the diagnostic end of these systems. As a result, the reader should begin by concentrating on the first nine generic chapters, then study the system-specific chapters that are of interest, and read the final two chapters last.
