Japanese roro chooses new J-Eng two-stroke

The C1 mark is a higher output version of the UEC45LSE engine in service since 2004 and aimed at roro vessels, handy-sized bulk carriers and small-sized chemical tankers. The series has accumulated more than 250 engine orders to date.

J-Eng noted that high reliability and low fuel consumption make the UEC45LSE ideal for roro vessels, with operators running demanding scheduled services and requiring tight control of costs.
