MAN Energy Solutions has reported that its ME-LGIA (Liquid Gas Injection Ammonia) engine, currently undergoing testing at its Research Centre Copenhagen facility, has run at 100% engine load for the first time.
Ole Pyndt Hansen, Head of Two-Stroke Research & Development, MAN Energy Solutions, said: “We began full-scale testing in November 2024 and have since proceeded in a cautious and safety-first way. We have now operated the engine on ammonia from 25–100% load, marking yet another important step forward in the maritime energy transition. As such, we have now validated the ammonia fuel-injection system over the full load-curve with diesel-pilot amounts recorded according to our targets. Furthermore, the positive emission and performance characteristics from previous, single-cylinder tests have now also been validated in full-scale engine operation.”
MAN states that its proprietary SCR (Selective Catalytic Reduction) was operational at all test loads to treat exhaust gases and that all supply and safety systems worked as intended. It also says that the next phase of testing will focus on performance and emission optimization, including injection and SCR systems as well as control strategies.
