A method for starting a camless internal combustion engine in response to a start signal, the internal combustion engine having a crankshaft and multiple cylinders each having one or more actuators for electronically actuating corresponding intake and exhaust valves, the internal combustion engine being mechanically coupled via the crankshaft to a starter motor, the starter motor being activated in response to the start signal, the method including the steps of: positioning each of the valves in accordance with a predetermined valve initial position, the valves being positioned so as to allow the flow of air in and out of each of the cylinders; rotating the crankshaft via the starter to a target idle speed for the engine; activating each of the valves in accordance with a predetermined valve activation sequence when the rotational speed of the crankshaft equals or exceeds the target idle speed; and activating each of the cylinders in accordance with a predetermined cylinder activation sequence after the valves have been activated. |
