What Is Hardware-in-the-Loop?
In Hardware-in-the-Loop testing, real components are integrated into a controlled test environment. This makes it possible to investigate operating conditions, aging processes, and interactions between media, components, and systems under application-relevant conditions.
Unlike purely simulation-based approaches, HiL testing generates real operating data that can be used directly for product development and optimization.


Why Hardware-in-the-Loop?
Hardware-in-the-Loop test benches enable real components to be evaluated directly under defined operating conditions. This allows interactions between fuels, media, and technical systems to be analyzed under realistic conditions without relying on costly long-term or field testing programs.
Key benefits include:
- Realistic testing conditions
- Reduced development effort
- Early identification of risks
- Fast comparison of different systems
- Reproducible results
- Lower testing and operating costs
Our Services
Component Qualification
Evaluation and qualification of technical components under realistic operating conditions. Targeted testing helps identify potential weaknesses at an early stage and provides valuable insights into the reliability, service life, and suitability of new components.
Fuel-Component Interaction Analysis
Investigation of interactions between fuels and fuel-carrying components such as pumps, filters, nozzles, and seals. This enables the early identification and assessment of material incompatibilities, deposit formation, and functional impairments.
System Comparisons
Direct comparison of different fuels, components, or technical systems under identical operating conditions. The resulting data supports informed development and investment decisions while helping identify optimal system configurations.
Development Support Testing
Application-oriented testing throughout the development process to identify technical risks at an early stage. These investigations provide robust data for optimizing products, components, and applications while reducing development cycles.

FAQ: Hardware-
in-the-Loop
What Does Hardware-in-the-Loop Mean?
Real components are tested under defined operating conditions to evaluate their behavior as realistically as possible.
What Are the Benefits of HiL?
HiL enables fast, repeatable testing with significantly less effort than full-scale field testing while still delivering highly relevant operational insights.
What Applications Are Possible?
Hardware-in-the-Loop can be applied to fuel systems, energy systems, component qualification, as well as investigations of interactions between operating media and technical components.
