Combustion Analysis Option

Combustion analysis options add dedicated software and hardware to your system for performing pressure-based combustion calculations. NI Combustion Analysis System (NI CAS) Software is a unique LabVIEW plug-in that provides numerous analysis functions, front panel controls, and utilities including data streaming to disk, preprocessing, heat release, pressure metrics, knock analysis, noise analysis, raw data logging, summary data reporting, and post-processing. NI CAS Software comes with an intuitive configuration-based startup
application that works out of the box. Take advantage of the library of functions to write custom code or incorporate other test and measurement capabilities.

Next-Cycle Control

You can implement next-cycle control with the LHP ECS+ when you choose a combustion analysis option. NI CAS Software features built-in functions for next-cycle control of your engine.
