5 facts about advanced cylinder lubrication technology

Lubrication technology for two-stroke engines plays a critical role in reducing wear, oil consumption, and emissions. At HJ Lubricators, we offer advanced solutions that deliver measurable improvements in engine condition and total cost of ownership (TCO). In this article we break down 5 important facts about advanced lubrication technology.

1. What is the purpose of lubrication technology for marine engines?

Lubrication technology for two-stroke marine engines involves the use of advanced lubrication systems to reduce friction between cylinder liner and piston rings by forming a thin and even oil film. Furthermore, lubrication prevents wear of liner and piston rings, neutralises sulphuric acids, keeps the piston, piston rings and cylinder liner free from deposits and provides a gas tight seal for improved overall efficiency of the engine.

Advanced lubrication systems ensure this oil film is delivered precisely – even under slow steaming or when using low-sulphur fuels – which is essential for maintaining engine performance and cylinder condition.

2. What is spray lubrication? 

Spray lubrication systems are used in marine vessels to inject a fine mist of oil into the combustion chamber under high pressure. The system utilises the scavenge air swirl inside the cylinder for optimal distribution on the liner wall and as an option for cleaning the piston and rings avoiding deposit build-up.

This technology is a core component of HJ Lubricators’ advanced lubrication systems, ensuring uniform distribution and protection across all critical liner zones.

3. How can high pressure lubrication systems benefit marine vessels?

A standard low-pressure lubrication system using non-return valves, distributes the oil vertically on the lower regions of the cylinder liner. Our research has shown that the oil film thickness on the liner tends to vary and, in some cases, over-lubricate locally.

Common rail technology uses high pressure to atomise the cylinder oil into the combustion chamber scavenge air swirl. Because the injection valves are angled for optimal and even distribution all over the upper part of the cylinder liner. This leads to better control and higher precision during lubrication.

Compared to traditional systems, advanced lubrication technology for two-stroke engines offers more precise feed rate control, better oil utilisation, and reduced liner wear.

4. What are the advantages of advanced lubrication systems for marine vessels?

The advantages of advanced lubrication systems for marine vessels include reduced oil consumption, improved cylinder condition, and reduced maintenance costs.

They also help ensure compliance with emission regulations such as IMO 2020, EEXI, and CII, by enabling fuel flexibility and minimising cold corrosion.

5. How can HJ Lubricators help your business?

If you are having problems with scuffing and cylinder breakdown, there is a good probability that replacing the existing lubrication system will improve the condition and reduce consumption.
