J-ENG To Develop Alt Fuel DF Engines With Licensee

The project is also expected to contribute to the development of technologies applicable to other alternative fuel types, such as methanol, in addition to to ammonia and hydrogen. The technology will have significant potential for future development, J-ENG claims.

Akasaka Diesels Ltd. has a long-standing relationship with J-Eng’s UE engines. The enterprise was originally established in 1960 with Mitsubishi Heavy Industries to manufacture and sell UE engines under licence. It has manufactured 1,528 small and medium-sized UE engines with a total capacity of 7,300,660 kW over the period.

The development of ammonia fuel engines and hydrogen fuel engines is receiving financial assistance from Japan’s New Energy and Industrial Technology Development Organization (NEDO) from its Green Innovation Fund.

The Motorship previously reported that J-ENG began to carry out R&D into the combustion of hydrogen and ammonia as fuel in collaboration with Japan’s National Maritime Research Institute in 2019.

In addition to the development of dual-fuel combustion technology, Akasaka noted that the agreement also includes the development of next-generation fuels at the company. In October 2022, Akasaka conducted an actual voyage test using biofuels on the coastal LPG tanker Tokuho Maru, which is equipped with an AX23B main mover.
