We want to share that our latest peer-reviewed paper has just been published in Automotive and Engine Technology:
“Experimental quantification and assessment of combustion anomalies under defined operating conditions of a heavy-duty hydrogen engine”
Key Highlights:
✅ Methodology developed to systematically detect and quantify combustion anomalies in a heavy-duty hydrogen internal combustion engine.
✅ Tests performed on a 9 L heavy-duty hydrogen engine (Liebherr H964) with dual-stage turbocharging and port-fuel injection
✅ Results show that anomaly occurrence strongly depends on ambient conditions — notably charge-air temperature and coolant temperature.
✅ Ignition timing is identified as a critical control lever: both advanced and delayed timing influence anomaly behaviour.
✅ The proposed test procedure proves reproducible and valid under engine-bench conditions.
This work advances our understanding of the limits and operational boundaries of heavy-duty hydrogen-fuelled ICEs and provides a robust framework for anomaly assessment.
Special thanks to all project partners and contributors from Graz University of Technology and industry collaborators within Hylley for making this possible.
