The UEC-LSII series, which includes the UEC85LSII, was introduced as the first full lineup series by Japan Engine Corporation (J-ENG), with the UE engine lineage dating back to 1955.
The UEC85LSII is part of the LSII series, which encompasses a bore size range from 33 to 85 cm. The LSII series is characterized by a stroke/bore ratio of less than 4.0, a Brake Mean Effective Pressure (BMEP) of 1.7 to 1.8 MPa, and a mean piston speed of around 8 m/s.
The UE engine series, including the UEC85LSII, is known for its high fuel efficiency, reliability, and environmental friendliness. J-ENG emphasizes low fuel consumption and reduced maintenance costs across its engine range.
