<p>The method involves diagnosing a thrust circulating air valve of a compressor in an air supply (10) of an internal-combustion engine. A pulsating difference of pressure over a component (5) of the air supply in the internal-combustion engine (1) is determined. Error is recognized using the determined pressure difference. A bypass valve (115) is accessed to open, when the air supply is throttled in a given value. An independent claim is also included for a device to operate an internal combustion engine.</p> |
