Abstract:
A method for initializing valves of an engine having a starting apparatus is disclosed. The engine may have electromechanically actuated cylinder valves. The method comprises moving at least a first valve away from a neutral position of the first valve before the engine is rotated by said starting apparatus; and moving at least a second valve away from a neutral position of the second valve after the engine is rotated by said starting apparatus.
