J-ENG Demonstrates First UEC50SJ-EGR Engine

By Jack Burke16 January 2019

Japan Engine Corp. (J-ENG) said it has demonstrated its first UEC50LSJ-EGR engine, which is designed for marine gasoil (MGO) and/or marine diesel oil (MDO) mono-fuel operation.

The engine, which is under development, is being subsidized by The Nippon Foundation, a private, non-profit organization that pursues maritime development and humanitarian work.

J-ENG’s UE engines are two-stroke, low-speed powerplants widely used in bulk carriers, tankers and other large vessels. The engine has a bore and stroke of 500 X 2300 mm.

The company said the UEC50LSJ engine will fully comply with the environmental requirements, including the upcoming global regulation to cope with SOx emissions. The company said the UEC-LSJ engine, by applying MGO and/or MDO, is a reliable solution because those fuels are stable and already used in the market.

This engine will contribute not only to save operation expenses by reducing its fuel oil consumption than that of conventional engine’s even using MGO whose price is supposed to be higher compared with current HFO, but also to improve EEDI, the company said.

The company said that performance optimization and reliability verification tests are being conducted, and the intended targets will be achieved, given current test results.
