ABSTRACT:
A method for regulating the mixture or fuel quantity fed to the cylinders of an internal combustion engine uses an arrangement for the variable metering of the mixture or fuel quantity to the cylinders of the internal combustion engine, a device for acquiring the actual value of the mixture or fuel quantity fed in, by means of measuring the stroke of a valve device, arranged movably in the metering arrangement, and an arrangement for regulating the valve movement. In order to be able to determine the actual value of the metered quantity with great accuracy where simple and cheap sensors are used, the stroke duration of the valve device allocated to each cylinder is determined with a position sensor and regulated to an identical value for all of the valve devices.
