China Yuchai has introduced a high-pressure, direct-injection internal combustion engine that runs entirely on ammonia. The system uses a specialized ammonia-to-hydrogen generation process and pre-chamber ignition to provide a zero-carbon alternative for long-haul commercial trucking. This technology aims to match the thermal efficiency of traditional diesel engines, addressing the range and weight limitations often found in battery-electric heavy trucks. The development supports China's broader strategic goals for carbon neutrality in the industrial transport sector.
