DMC’s solution characterizes fuel injectors for research and product development by optimizing injector control timing. Engineers may characterize fuel injector designs to match them with evolving engine needs. After migrating controls from disparate benchtop instruments to a singular control and data acquisition system capable of measuring and viewing critical parameters, these integrated tools become the basis for a fully automated characterization system. Each injector is characterized to ensure the performance and product. This solution can be scaled up to different product development needs and manufacturing testing. An advanced data viewer is used to mine data for statistical evaluation of injector performance. These LabVIEW data processing tools are best in class, as the NI hardware platform allows scalability without programming changes.

  • Automated rate trace analysis
  • Critical parameter sequencing and optimization detection
  • Intelligent storage and retrieval for efficient Engineering decisions
  • Shorter product development time
  • More efficient and accurate testing systems
  • More effective design decisions due to identification of critical parameters and specifications
  • Better product characterization with automatic test routines coupled with manual diagnostic tools
  • Testbed can be leveraged for future products
  • Improved end product quality, as variations are caught more thoroughly and information is stored for matching with other components
  • Reduced manufacturing cycle time, as algorithms for characterization run more quickly than previous methods
