HJ Lubricators | Oceanist Engineering
Leading Cylinder Lubrication Technology
HJ Lubricators is the world’s leading provider of cylinder lubrication systems for two-stroke marine engines. Backed by dedicated specialists, we reduce cylinder oil consumption by up to 60% while improving engine condition—supporting the green transition through lower oil usage and reduced emissions.
Our advanced solutions significantly decrease cylinder lubricating oil consumption by up to 60%, while extending the lifetime of cylinder liners and piston rings. Optimized lubrication leads to reduced CO₂ and particulate emissions and improved overall engine efficiency.
Patented Technology
HJ Lubricators’ patented HJL technology injects fresh cylinder oil during every piston stroke, utilizing an atomized oil spray to ensure optimal lubrication of the cylinder surface.
Our systems allow stepless adjustment of the lubrication quantity and enable multiple injections per engine revolution, ensuring precise oil delivery under all operating conditions. HJ lubricators are installed both in newbuild vessels and as retrofit solutions.
