Low cylinder oil consumption levels can be achieved for all major design of two stroke diesel engines applying a better method of distributing the cylinder oil to the running surface of the liner than just relying on the piston rings.
Spraying the oil onto the liner surface using the Swirl Injection principle allows lower consumption and very low wear rates at the same time.
The SIP principle was introduced at CIMAC 2001 in Hamburg, and is now under application for 29 large bore engines (retrofit and newbuildings alike). All registered experience data are positive.
For reference on a MAN B&W K90MC engine the consuption is at 0.43g/BHPh (MCR) while the liner wear does not exceed 0.013 mm/1000h. This is rather good for a container vessel!

Application take place in close cooperation with the engine desingers.
