J-ENG receives orders for main engine, “6UEC60LSJA-HPSCR” for four Ammonia-Fueled Pure Car and Truck Carriers

Japan Engine Corporation (J-ENG) has been awarded orders for four main engines, designated "6UEC60LSJA-HPSCR," which are fully made in Japan and designed for ammonia-fueled propulsion. These engines will power four new Pure Car and Truck Carriers (PCTCs) as part of a joint project to develop and operate ammonia-fueled vessels, announced by seven companies on October 27, 2026. The project aims to decarbonize international shipping and establish an ammonia fuel supply chain based in Japan's Chubu region.

J-ENG is actively involved in the "ALL JAPAN" project, which covers every aspect of the project, from ammonia fuel procurement and supply to vessel construction and operation. The company will provide the engines with its integrated framework for development, design, manufacture, and after-sales service. Ammonia, when burned, emits no CO₂ and is considered one of the most promising alternative fuels to achieve net-zero emissions in shipping by 2050.

However, the practical use of ammonia as a fuel requires advanced technologies to address its toxicity, low flammability, and emissions such as N₂O and NOx. J-ENG has already demonstrated the environmental performance, reliability, and safety of its engine through extensive testing under the Green Innovation Fund Project "Development of Next-Generation Ships" by NEDO.

The new orders for four "6UEC60LSJA-HPSCR" engines mark a significant step towards integrating this technology on commercial vessels. J-ENG, as a licensee of fully Japan-made low-speed marine engines, will leverage its expertise to support the project's growth and contribute to the reduction of greenhouse gas emissions, the achievement of net-zero emissions in international shipping by 2050, and the enhancement of Japan's maritime industry competitiveness.
