초록 ▼

A method of attaining a desired engine performance comprises the steps of changing the angular position of a variable camlobe (or cam) member relative to a fixed camlobe (or cam) member from a first angular position to a second angular position. In changing from the first to the second angular position, the variable camlobe (or cam) member moves in a predetermined direction relative to the direction of rotation of a camshaft. The predetermined direction and the magnitude of the angular movement of the variable camlobe (or cam) member is dependent at least in part upon at least one desired operating condition of the engine. The method further comprises changing the angular position of both camlobe (or cam) members relative to a reference point of a drive pulley. This change in the angular position of both of the camlobe (or cam) members relative to the reference point involves movement of the camlobes (or cams) in a direction relative to the direction of rotation of a camshaft. The direction and magnitude of this movement is based at least in part upon at least one desired operating condition of the engine.

In an internal combustion engine having an intake valve, an exhaust valve, valve events consisting of opening timing and closing timing of a valve and a single camshaft rotatable in a first direction and with an intake cam member and an exhaust cam member, one of said cam members being a splittable cam member comprising a first camlobe member and a second camlobe member wherein the angular positions of said first camlobe member is variable relative to said second camlobe member and is at a first angular position relative to same, the other cam member being at a fixed angular position relative to said camshaft and said second camlobe member, an electronic control unit controlling the angular position between said camlobe members depending upon at least one of the engine operating parameters and desired engine operating conditions, a method of attaining a desired engine performance, comprising the steps of: changing the relative angular position of said camlobe members from said first angular position to a second angular position so as to optimize one of the valve events of the valve being actuated by said splittable cam member without changing the other valve event of the same valve and doing so at at least two combinations of speed and load at which the engine is operating.
