FEV GmbH with headquarters in Aachen is an independent, internationally leading company for the development of combustion engines, transmissions and complete vehicle drive systems. Furthermore, FEV develops, produces, and distributes measurement and test systems for the development and final inspection of vehicle drives.
When it comes to tasks like combustion process development or calibration, engine developers need to analyse the combustion process in even more detail than ever before. Therefore, FEV has developed the FEVIS indication system in cooperation with NOFFZ which combines powerful modular hardware for data acquisition with a familiar MS Windows-based user interface.
The novel indication system contains a calculation library with more than 100 formulas which can be viewed simultaneously, calculated and stored for each individual cylinder. The system works in real-time, i. e. synchronously with the engine cycle. With the integrated engine knock analysis and the simultaneous limit value monitoring the indication system FEVIS can also be used for the safety monitoring of the engine to be tested. An exceeding of the limits can be used to control external devices via analogue and digital outputs.
