Publication: Transient Response
We’re excited to announce that our latest peer-reviewed paper has just been published in Automotive and Engine Technology:
🔍 "Experimental investigation into transient operating strategies of a turbocharged lean-burn hydrogen ICE and comparison to diesel performance"
Key highlights:
✅ Experimental investigation of a 9L hydrogen ICE (Liebherr H964)
✅ Development and testing of transient control strategies (acceleration enrichment + ignition retard)
✅ Analysis of the trade-off between torque response (t70%) and NOₓ emissions
✅ Performance comparison with a diesel reference engine (Liebherr D964)
This work underlines the importance of transient control strategies for making H₂-ICE a viable alternative to diesel, especially in demanding mobile applications. While significant progress has been made, further hardware and control improvements are needed to close the performance gap to diesel engines.
🔬 All work was conducted at the Graz University of Technology in collaboration with our academic and industry partners.
🙏 Special thanks to Liebherr for providing the engine platform and reference data, and to all Hylley partners for their continued support.
