APPARATUS AND METHOD FOR CONTROLLING THE FLOW OF CRANKCASE EMISSIONS IN AN INTERNAL COMBUSTION ENGINE

Title:

APPARATUS AND METHOD FOR CONTROLLING THE FLOW OF CRANKCASE EMISSIONS IN AN INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO1998028529

Kind Code:

A3

Abstract:

An apparatus is provided for controlling the flow of crankcase emissions. The apparatus includes a crankcase emissions regulator for regulating the flow of crankcase emissions discharged from an engine crankcase, a pressure sensor for sensing a crankcase pressure, and an electronic control module (ECM) for controlling the emissions regulator. The ECM adjusts the emissions regulator in response to the pressure differential between the detected crankcase pressure and a predetermined pressure value programmed in the ECM.
