Abstract
A closed crankcase ventilation system for a recirculating effluent gas stream of an internal combustion engine is provided with an air flow meter. The flow meter provides a signal to an engine controller continuously during normal engine operation that is proportional to the flow of gas through the system. The signal is used to trigger a control system output that may activate an alarm, shutdown the engine, or indicate a need for engine service.
