Abstract
An evaluation device for producing an interference free output signal from a measuring signal of a lambda probe arranged in an exhaust gas outlet of an internal combustion engine includes the following function units: an integrator for integrating the measuring signal from the probe for an adjustable time interval; a computer for computing from predetermined operational variables of the engine periods of pressure pulsations of the exhaust gas; and a computerized timer cooperating with the computer to define a time interval for the integrating operation corresponding to an integer multiple of a period of special pulsations computed by the computer.
