Commercial Hydrogen Engines: Methodologies for rapid mechanical development and validation

Hydrogen engine development faces critical challenges to ensure robust and reliable performance in real-world applications. Adequate lube oil selection is key, as it influences combustion stability and long-term engine performance. An advanced lube oil screening method allows early-stage testing of long-term effects, such as increased oil consumption due to wear. Optimizing oil formulations and engine boundary conditions for controlled pre-ignition can offer significant benefits. Additionally, managing high water condensation in the crankcase under low load and cold conditions necessitates a thorough evaluation of ventilation systems and oil strategies. AVL's water accumulation testing provides an effective method for rapid evaluation and optimization.
