Reduce the risk of scuffing in cylinder liners

Scuffing in cylinder liners is a serious risk for marine vessels that might lead to costly engine repairs and prolonged downtime. By understanding the causes, you can take preventive measures to reduce the risk of scuffing and ensure optimal engine performance, reliability, and longevity. With the right knowledge and precautions, you can protect your engine against cylinder scuffing and enjoy efficient operations and lower maintenance costs.

What is cylinder scuffing?

Cylinder scuffing is a form of micro welding or direct contact between the cylinder liner and piston rings. This occurs when the lubricant film breaks down or fails due to various reasons, leading to noticeable friction wear that can be identified by observing a dragged or furrowed appearance on the liner surface.

If left unaddressed, cylinder scuffing can lead to significant damage to the engine, resulting in reduced efficiency, increased maintenance costs, and potentially equipment failure. Therefore, preventing cylinder scuffing is crucial for optimal engine performance, efficient operation, and safe equipment handling.

What causes cylinder liner scuffing?

Running a two-stroke engine efficiently is becoming increasingly complex. Enhanced environmental regulations (such as SECA, IMO2020, EEXI and CII), changes in marine engine design (now operating at higher temperatures and pressures), new operation requirements (slow steaming/part load operation), and the reduced specialism of crew all add to this.

As mentioned, cylinder liner scuffing is a common risk that can significantly impact engine performance and cause extensive damage to equipment. The scuffing can occur due to several reasons, including:
