HJ Smartlube 4.0
Revolutionizing lubrication technology for 2-stroke marine engines.
Patented by Hans Jensen Lubricators.
Advanced commonrail technology, integrating lubricator and valve in one compact unit.
Compact design
HJ Smartlube 4.0 is a unique combination of compact design and advanced functionality.
The system integrates the lubricator into the HJ SIP (Swirl Injection Principle) injection valve, thereby completely eliminating the need for an individual lubricator on each cylinder.
This means that the system consists of fewer parts, making maintenance and trouble-shooting faster.
Patented technology
The system injects fresh cylinder lube oil during each piston stroke to prevent wear and corrosion of the liner.
The system atomizes the cylinder oil into the combustion chamber using the scavenge air swirl at high pressure.
The result is an optimal distribution of the oil on the upper liner surface which is the most vulnerable part of the cylinder.

- Sulphur-, load- and BN-dependent algorithms
- Possibility for online monitoring and preventive alarms
GET THE BENEFITS OF:
Multi-timing
Multiple cylinder oil injections in a single piston stroke. For example:
1 x injection into the scavenging air swirl above the piston, covering the upper liner surface to protect the combustion area;
1 x injection into the ring pack (combustion stroke) for enhanced cleaning;
1 x injection into the ring pack (compression stroke) for enhanced cleaning (optional)
… all in the same piston stroke!
Flexible injections
Volume adjustment of every injection: Every valve can individually adjust the opening time very precisely, which allows each valve to apply different feed rates. Imagine a 60-bore cylinder with 6 injection valves where it is possible to adjust different volumes at every single valve.
Automatic Cleaning Sequence (ACS)
ACS will automatically increase the cylinder oil consumption for a limited period of time. This “boost” of extra oil ensures optimal cleaning of liners and rings, keeping them free from deposits.
Internet-Of-Things Connectivity
The system allows remote operation through an upgradable module of the onboard computer. This allows your technical management team to ensure the correct feed rate is employed.
