Abstract: A method according to the invention for controlling an internal combustion engine having a camshaft whose phase with respect to a crankshaft can be adjusted by means of an electric adjustment device, and a control device comprises the steps S1 to S3, wherein in step S1 a stop request is output from the control device to the electric adjustment device. Subsequently, in step S2 a manipulated variable in the form of a pulse duty factor is output from the electric adjustment device, wherein the pulse duty factor counteracts a camshaft torque. In step S3, the direction of rotation of the camshaft is monitored, wherein in step S4, when a reversal of the direction of rotation of the camshaft is detected, an intensity level of this reversal of the direction of rotation is calculated by determining a rotational speed gradient. Furthermore, in a step S5 the pulse duty factor is corrected as a function of the rotational speed gradient in such a way that the influence of the reversal of the direction of rotation on the position of the camshaft is compensated.

Abstract: An engine is provided with a variable valve timing device which transmits a rotational force generated by a motor via a motor drive circuit to a cam shaft so as to change a rotational phase of the cam shaft relative to a crank shaft. An ECU cools a motor and a motor drive circuit when the change of the rotational phase stops during the changing of the rotational phase of the cam shaft to a target value is detected. In addition, the lock state is eliminated by driving the motor by the motor drive circuit after cooling the motor device.

Abstract: A modified rocker assembly having an offset end is designed to be used in engine heads having an obstruction that would not allow a switching rocker arm to be used. The modified rocker assembly is described having an obstructed side and a non-obstructed side. The rocker assembly has an outer structure with a first end, and an inner rocker structure fitting within the outer structure, the inner structure also having a first end. The modified rocker assembly has an axle pivotally connecting the first ends of inner structure to the outer structure, such that the inner structure may rotate within the outer structure around the axle. At least one torsion spring on one side of axle, rotationally biases the inner structure relative to the outer structure. The outer structure, on the obstructed side as it extends from the second end toward the first end, is offset toward the non-obstructed side creating the first offset portion to provide additional clearance on the obstructed side. This design allows the modified rocker arm to fit into an engine head having an obstruction on its obstruction side.
