Operating internal combustion engine crankcase ventilation system, especially in motor vehicle, involves leak testing gas path by subjecting system to test pressure, comparing pressure variation with predefined/computed desired profile
摘要
<p>The method involves leak testing a gas path (7) by subjecting the internal combustion engine (1) crankcase ventilation system (2) to a test pressure and comparing the variation of the pressure the gas path with a predefined or computed desired pressure profile. The leak test is conducted with the internal combustion engine running. An independent claim is also included for a crankcase ventilation system.</p>
