Development of an ammonia engine without greenhouse gas emissions → To be used in vehicles and ships

Machine Research Institute Develops Core Technology, ‘A 2-liter engine using ammonia, a renewable energy source without greenhouse gas emissions, has been developed. This technology is expected to be utilized as core technology in various fields such as power sources for vehicles, ships, aviation mobility, and industrial generators.’,
,
, ‘The team, led by Principal Researcher Park Chul-woong from the Eco-friendly Mobility Research Department at the Korea Institute of Machinery & Materials (Director Ryu Seok-hyun), along with Hyundai and Kia’s Electrification Design Center, has jointly developed the world’s first engine that directly injects ammonia into the combustion chamber under high pressure.’,
,
, ‘The main feature of the developed engine is that it can use ammonia, a hydrogen carrier, directly as fuel without a separate decomposition process. It improves upon the unstable output and high harmful emissions associated with gaseous fuel methods by adopting a high-pressure liquid injection method.’,

,
, ‘Using the high-pressure liquid injection method allows a stable supply of large-capacity ammonia fuel. It achieves world-class specific power with pure ammonia, making it usable without separate combustion enhancement devices or additives.’,
,
, ‘The research team further improved performance by optimizing the ignition system, fuel injection timing, and intake/exhaust valve timing. Additionally, by implementing an ammonia-dedicated post-processing system, they minimized emissions of nitrogen oxides and unburned ammonia. As a result, thermal efficiency and output increased significantly, while harmful emissions were drastically reduced.’,
,
, ‘Principal Researcher Park Chul-woong stated, “This technology is a new concept that dramatically improves the performance of existing ammonia engines,” adding, “It will change the paradigm in areas such as mobility power sources and clean hydrogen power generation in industrial generators.”’,
,
, ‘Lee Seung-woo, Principal Researcher at Hyundai and Kia, mentioned, “It will establish itself as a new clean fuel-based power source that can solve the challenges of hydrogen transportation and green hydrogen production.”’,
