Patent ID: 8813714

Claim:
A method for lubricating cylinders in large diesel engines, where injection of lubricating oil is performed via a number of injection units corresponding to a multiple of the cylinder number in the engine, where the lubricating oil is supplied as a combination of injection of at least two parts of the lubricating oil, where said at least two parts of lubricating oil is delivered in at least two different piston positions, where the at least two different piston positions are selected among piston positions for injecting before, during and after the passage of the piston by the injection unit, and where the lubricating oil is supplied by injection directly on a ring area of the wall of the cylinder, wherein the lubricating oil is supplied by a combination of injection of a first part of the lubricating oil above the piston directly on the ring area of the cylinder wall before the passage of the piston, and an injection of a second and/or third part of the lubricating oil, as the second part of the lubricating oil is injected directly on the piston during its passage, and as a third part of the lubricating oil is injected directly on the ring area of the cylinder wall under the piston after passage of the piston, characterized in detection of an indirect or direct parameter for actual cylinder load is performed, and that a distribution between the first and second and/or third parts of the lubricating oil is made such that the second and/or third parts are increased proportionally by reduced cylinder load.
