Our products
HJ Lubricators is an independent supplier of lubrication technology for large 2-stroke marine engines. As an OEM we control our own manufacture of pumps, valves and the equipment needed for our solutions.
PATENTED TECHNOLOGY
Cylinder oil injection in every piston stroke
A unique feature of HJ Lubricators is the ability to inject fresh cylinder lube oil during each piston stroke to reduce engine wear and corrosion. The dosage of oil is adjusted for optimal effect.
Experience up to 50% less lube oil consumption with HJ lubrication technology compared to standard lubricators.
PATENTED TECHNOLOGY
Atomizing cylinder oil into the combustion chamber
HJ SIP valves (Swirl Injection Principle) is the principle of atomizing cylinder oil and injecting it into the scavenge air swirl at a high pressure. The result is an optimal distribution of the cylinder oil on the entire upper liner surface (combustion area) which is the most exposed area in the engine.
Our lubricators & valves
HJ Smartlube 4.0
The compact design eliminates the need for an individual lubricator on each cylinder, meaning that the system consists of fewer parts, making maintenance and trouble-shooting faster and more user-friendly.
HJ Lubtronic 2.0
Electronically controlled cylinder lubricator allowing the injection of fresh cylinder oil during each piston stroke. Features algorithm that changes crankshaft angle at which cylinder oil injected.
HJ X-Tronic
Add-on electronic control system that can be retrofitted to existing mechanical lubricators, making the lubrication system electronically controlled with load and sulphur regulation.
HJ Mechtronic
Electronic control system that can be retrofitted to existing mechanical lubricators, making the lubrication system electronically controlled with load and sulphur regulation and, at the same time, reduce cylinder oil.
HJ SIP valves
Our unique SIP-valves atomize the spray of cylinder lubrication oil into the combustion chamber using our patented Swirl Injection Principle. The engine scavenge air is utilized for efficient distribution inside the cylinder.
HJ SIP + valves
SIP+ sets a new standard in cylinder lubrication. Built on the proven Swirl Injection Principle, the redesigned SIP+ valve enables easy installation without cylinder liner machining or top cover removal—cutting time, cost and downtime.

Product FAQ
There are four main benefits. The cylinder lubrication system distributes a thin and even oil film on the cylinder liner that minimizes wear. The beneficial chemical compounds of the cylinder oil neutralize sulphury acids formed during combustion on piston rings and cylinder liners. The oil also keeps the cylinder free from deposits as well as provide a gas tight seal between the liner and piston rings.
If you implement EPL to comply with EEXI, it most likely means that you reduce the load of the engine. When the load is reduced, the OEM cylinder lubrication systems reduce the injection frequency of the cylinder oil. In other words, the engine will run on ‘old’ oil, during an increased number of dry piston strokes.
Our approach is therefore injection of oil in each piston stroke, which prevents a deteriorated cylinder condition even at reduced loads.
• Reduces operational cost for cylinder lubrication oil by up to 50%
• The cylinder condition is improved using efficient lubrication technology
• Extend the life time of cylinder liners and piston rings (TBO)
• Reduce the work load for engine crew
• Reduce the CO2 and Particulate Matter (PM) emissions
• Prepare for EEXI and the use of greener fuels
