Efficient cylinder lubrication is vital for the reliable operation of marine engines, supporting operational efficiency, emission reduction, and the prevention of costly wear such as scuffing. HJ Lubricators recommends integrating robust cylinder lubrication systems as part of a vessel’s holistic approach to engine care, particularly where maximising uptime and meeting stringent IMO emission requirements are Read more

In two-stroke marine engines, scavenging air isn’t just for clearing combustion gases—it plays a crucial role in oil distribution. The swirling air helps to disperse lubricant evenly across the cylinder liner. But achieving this balance is complex, especially under varying load conditions. Poor scavenging leads to localised wear, excess oil consumption, and higher emissions. By Read more

How much cylinder oil are you wasting? Use our oil consumption calculator to find out Excessive cylinder oil consumption remains a significant operational and cost challenge for shipowners and operators. With stricter IMO regulations and growing attention to sustainability and cost efficiency, monitoring and optimising oil usage is more important than ever. At HJ Lubricators, Read more
