Abstract

A method of testing the exhaust gas emission of an internal combustion engine which comprises testing the ignition timing when idling, determining the air coefficient for example by determining when idling, a component or components of the exhaust gases, and carrying out at least one determination of the air coefficient lambda at different rotational speeds under zero load.
