Abstract

PURPOSE: The output characteristics of negative pressure amplifier which drives an EGR valve by magnifying negative venturi pressure are corrected by negative manifold and venturi pressure so that the reduction of output is limitted to the minimum at all the running conditions,and the optimal EGR quantity is obtained.
