China Yuchai International has developed a high-pressure, direct-injection internal combustion engine that runs entirely on ammonia. This technology targets heavy-duty commercial vehicles, offering a zero-carbon alternative with thermal efficiency levels similar to traditional diesel engines. The move signals a shift toward ammonia as a viable fuel for decarbonizing long-haul transport and heavy machinery. While the company continues to generate cash from diesel sales, this innovation aims to reduce reliance on fossil fuels in the commercial transport sector.
