This groundbreaking technology is expected to serve as a foundational platform for various applications, including vehicles, ships, aircraft, and industrial power generators.
The Korea Institute of Machinery and Materials (President Seog-Hyeon Ryu, hereinafter referred to as KIMM) announced that it has developed the world’s first engine capable of directly injecting ammonia into the combustion chamber at high pressure, in collaboration with the Electrification Engineering Center of Hyundai Motor and Kia.
The new engine utilizes high-pressure liquid injection technology to address challenges associated with gaseous ammonia fuels, such as unstable power output and harmful emissions. This system ensures a stable supply of large volumes of ammonia fuel.
The research team enhanced the engine’s performance by improving the ignition system and optimizing the timing of fuel injection and valve operation. Additionally, they developed a dedicated after-treatment system to minimize nitrogen oxides (NOx) and unburnt ammonia emissions. As a result, the engine demonstrated significantly improved thermal efficiency and power output, while drastically reducing harmful emissions.
