UE Engine

About UE Engines

The UE Engine has its roots in the MS diesel engine originally developed by Mitsubishi Heavy Industries in the 1910s, and is the only Japanese-domestic brand for marine low-speed engines.
It is constantly evolving while incorporating the latest technologies in order to respond to market trends and diversifying customer needs, and is used by many vessels around the world, including bulk carriers, tankers, car carrier ships, and container ships.

UE Engine Characteristics

History of UE Engine’s fuel consumption

(1)Low Fuel Consumption

The strength of the UE engine is that it achieves the industry’s highest level of fuel efficiency that far surpasses competitors with its cutting-edge technology. For more than half a century since the first engine was manufactured in 1955, we have been striving to further improve the fuel efficiency through various efforts such as reducing mechanical loss, reducing heat loss, and optimizing the fuel injection system.

(2) Our Unique Technology to Clear Environmental Regulations

The UE Engine meets the regulations set by the International Maritime Organization, such as those for nitrogen oxide, sulfur oxide, and carbon dioxide, while at the same time applying our own unique technologies such as a low-pressure EGR and SCR systems that are advantageous for maintenance.

(3)Compact Design

Ships will be able to carry more cargo by adopting a development concept of compact main engine.

(4) Ease of Maintenance

Maintenance is easy thanks to the simple structure. Also, as even the exchangeable parts can be used for a long period of time, our customers will be able to reduce maintenance costs.

Our latest, cutting-edge models are the LSH Series and the LSJ Series.
The LSH Series is an engine that seeks low fuel consumption on the premise of using conventional fuels and compatible oils.
The LSJ Series is an engine equipped with our independently-developed stratiform water injection technology from the LSH Series, and as it only uses marine gas oil or A heavy oil as fuel, it has better fuel efficiency than the LSH Series. We are developing so that high fuel costs can be offset by low fuel consumption and low maintenance costs, allowing you to experience a total cost advantage.
