HJ X-Tronic
Electronic control system for mechanical lubricators
that converts to load dependent lubrication.
SAVINGS
Reduces cylinder oil consumption by up to 50%.
LINER LIFETIME
Improves cylinder condition significantly
REDUCE EMISSIONS
Lower particle matter and CO2 emissions
Easy add-on solution
HJ X-Tronic is an electronic regulation unit that converts mechanical lubricators from RPM-dependent to BHP- (load)-dependent.
HJ X-Tronic ensures that the cylinder oil consumption is adjusted automatically to match the current operating conditions such as load %, BN-level or the type of fuel, including the sulphur %.
The majority of older vessels still using original lubrication systems have higher than necessary lube oil consumption, which is not only expensive but also potentially harmful for the engine in the long run.
By retrofitting with HJ X-Tronic, you will experience significant savings in cylinder oil consumption by up to 60%, as well as improved engine conditions.




Benefits
- Up to 50% reduction of cylinder oil consumption
- Reduced wear of liners and rings
- Improved acid neutralization and reduced corrosive wear
- Reduced emission of particle matter and CO2
- Extended TBO
- Easy operation for crew
Product features
- Oil injection in every piston stroke
- Feed rate regulation depending on load or Sulphur level
- Automatic Cleaning Sequence algorithm (patented technology)
- Delta-Timing algorithm ensures lubrication both into ring pack and liner
- Sulphur-, load- and BN-dependent algorithms
- Possibility for online monitoring and preventive alarms
- Using HJ SIP valves:
Atomizing cylinder oil into the combustion chamber lowers oil consumption further

Product FAQ
The current conventional mechanical lubricators are improved using HJ X-Tronic. The lubricator enables electronic control and automatic regulation of oil according to engine load.
It takes the position of fuel regulation shaft multiplied with engine RPM and calculates engine load. It thereby calculates how much oil should be injected into each cylinder during each revolution.
The electronic actuator adjusts the feed rate on each lubricator (not each lubrication point) according to load or sulphur level.
Yes. It is possible to install an analog flow-meter, which can be connected to HJ X-Tronic. This allows crew to monitor actual oil flow on the flow-meter counter.
Our engineers will conduct the installation in-situ, onboard your vessel, when it is convenient for you. Assistance from crew is needed for welding and cutting the control boxes.
Approximately 4-5 working days, likely less with crew assistance. Much of the work takes place “outside the engine”, so this can be performed during normal vessel operation.
