Method for monitoring of exhaust of crank case of internal-combustion engine, involves determining mass flow upstream in intake line and mass flow downstream in intake line

摘要

The method involves determining a mass flow (m-1) upstream in an intake line (1) and mass flow (m-2) downstream in the intake line. An enthalpy current (h'-1,h'-2) is determined by mass flows and pertinent temperatures (T-1,T-2). A crankcase emission control is extinguished from the efficiency and deficiency of a crankcase emission control.
