Title:
内燃機関の異なるシリンダーバンクのカムシャフトを同時に位置調節するための方法
Document Type and Number:
Japanese Patent JP2004517241
Kind Code:
A
Abstract:
A method for simultaneously adjusting camshafts of different cylinder banks of an internal combustion engine to a predetermined nominal angle relative to a crankshaft, where the camshafts actuate associated intake or exhaust valves of the corresponding cylinder banks of the internal combustion engine. The method includes the steps of: detecting a difference in adjusting speeds of associated actual angles of the camshafts, and changing over the time nominal angle of at least one of the camshafts with a higher adjusting speed until the actual angles of the camshafts have reached the original nominal angle. The nominal angle for the camshaft with the higher adjusting speed is changed over time so that a divergence between the actual angles of the camshaft with the higher adjusting speed and the actual angles of the camshaft with the lowest adjusting speed is first stopped and a then corresponding difference between these actual angles is reduced.
