Abstract
A method is disclosed for initiating oil injection into a cylinder of an internal combustion engine prior to engine start-up, the oil injection protecting the engine from damage caused by insufficient lubrication during the start-up. The method includes processing data to modulate a lubrication initiation modifier and initiating the oil injection on the basis of the lubrication initiation modifier.
