Cylinder honing

Article Abstract:

Cylinder honing can remove minor surface imperfections created by acidic corrosion, broken piston rings, and scuffing and vertical scoring from carbon deposits. Apart from extending the life of a cylinder liner, honing can lower lubricating oil costs by removing glazing. There are several ways of honing within a cylinder lining, each of which can yield cost savings that pay for themselves within two years. Three companies produce in-situ honing systems that cost-conscious shipowners may prefer: Brush Research Manufacturing, Chris-Marine and Wakefield.

Saddle solutions

Article Abstract:

MAN B&W Hamburg recommends time and cost-effective service procedures for its two-stroke KZ and KSZ type marine engines during slackening of the main bearing connections. Visual inspection and measurement of the back of the main lower bearing shell can be used to identify the extent of the problem and often prevent further damage to the saddles. The firm has developed a method of matching the main bearing saddles which does not require the removal of the crankshaft and cylinder units from the engine, thereby reducing the service time considerably.

Drycleaning beats the wet?

Article Abstract:

Drycleaning is fast becoming an alternative to the water washing technique being employed in the cleaning of compressor wheels and turbines of marine engines. The dry cleaning technique uses corn, rice or other abrasive grains to remove residues from the parts. The technique allows cleaning to be done without reducing engine speed aside from reducing the risks of thermal shock where engine parts are made more prone to damage due to sudden changes in temperatures.
