SYSTEM AND METHOD FOR PREVENTING ICING IN POSITIVE CRANKCASE VENTILATION SYSTEMS
A control system for an engine includes an icing condition detection module and an icing prevention module. The icing condition detection module detects an icing condition of a positive crankcase ventilation (PCV) system of the engine when an ambient temperature is less than a predetermined temperat...

| description | A control system for an engine includes an icing condition detection module and an icing prevention module. The icing condition detection module detects an icing condition of a positive crankcase ventilation (PCV) system of the engine when an ambient temperature is less than a predetermined temperature for a first predetermined period. The icing prevention module increases engine speed for a second predetermined period when the icing condition is detected. |
