Abstract
An internal combustion engine has a plurality of cylinders to which in each case at least one inlet valve and one outlet valve are assigned. A valve drive is assigned for controlling the inlet valve and a valve drive is assigned for controlling the outlet valve. The valve control time for the inlet valve of a cylinder is calculated at least one segment later than the valve control time for the outlet valve of the same cylinder. The segment is determined by the phase angle between the upper dead centers of two pistons of cylinders which follow one another directly in the ignition sequence.
Claims5
A method for controlling an internal combustion engine having a plurality of cylinders, to which in each case at least one inlet valve and one outlet valve are assigned, comprising:
- controlling the at least one inlet valve and the at least one outlet valve using a first and second valve drive, respectively, wherein a first valve control time for the inlet valve of a cylinder is calculated at least one segment later than a second valve control time for the at least one outlet valve of the cylinder, a segment being determined by the phase angle between the upper dead centers of two pistons of cylinders which follow one another directly in the ignition sequence.
