Quickly ready for use, the system can be connected up directly to calibration tools, such as INCA. This means IAV Indicar is not only suitable for use on the test bench but can also be taken on test drives without a problem.
IAV Indicar records as many as eight cylinder-pressure signals on a cycle-accurate basis and processes them in real time under thermodynamic aspects. Unlike other comparable indication systems, IAV Indicar impresses with real-time signal-evaluation capability – e.g. for closed-loop control of PMI and main center of heat release.
Users can work with the ready-made thermodynamic block sets supplied with the system or add their own MATLAB / Simulink algorithms for processing signals. The data computed can be exported in different formats for further analysis by the user.
Besides the standard configuration, we can also provide the IAV Indicar with additional inputs and outputs in line with client needs. The unit includes our Indicar Commander software for configuring the system as well as for recording and evaluating data.
