Description
Abstract
The project investigates pre-ignition phenomena for further development of marine dual-fuel/gas engines. Previous studies on lube oil self-ignition mechanisms will be extended to include exhaust gas recirculation and, besides methane as fuel, carbon-free ammonia and hydrogen blending. Besides pre-ignition itself the regular ignition process (turbulent jet and/or pilot fuel) will be assessed. Using an optically accessible engine test facility with selective lube oil addition, pre-ignition kernels, ignition behavior and influence of operation conditions will be analyzed. Moreover, interacting flame fronts, accelerated flame propagation, and transitions to knocking will be studied. The analyzed reference data supports predictive pre-ignition model development.
