procedure for measuring partikelhalten in exhaust gas of an internal combustion engine

摘要

A method of measuring the particle content, in particular the soot particle content, in the exhaust gases of an internal combustion engine using a sensor arranged in contact with the exhaust gases. The sensor detects in at least one combustion chamber of the internal combustion engine an electrical quantity, the size of which is dependent on the particle content in the exhaust gases. The level of a measurement signal output from the sensor, the signal is dependent on the detected quantity, is determined and compared with a desired value level of a signal which corresponds to a desired particle content in the exhaust gases.
