Technical development proceeds with shorter periods. As a logical consequence new technical terms and phrases arise. Certain known terms can then no longer be understood and be used in their original form or they can get a new meaning. Therefore advanced technology requires more and more specializing. This dictionary is meant to facilitate, in conjunction with the integrated glossary and tables of data, the gap from the every-day language to the scientific technical one. It contains the most important and frequently used terms of components and systems of vehicles and related phrases. The Dictionary of Automotive Engineering is a useful tool for the expert, the student, and the enthusiast of the automobile technique.
