Document Type and Number:
Japanese Patent JPS6248048
Kind Code:
B2
Abstract:
A system for controlling emissions of particulates and heavy organic vapors in the exhaust gases of diesel engines includes, in a preferred embodiment, a heat exchanger for cooling the engine exhaust gases below the condensation temperature of the organic vapors and their resultant adsorption onto the entrained particulates, and a particulate trap connected to receive the cooled gases from the heat exchanger and collect therefrom entrained particulates and heavy organic vapors adsorbed thereon. A bypass system is provided to direct high temperature exhaust gases around the filtration device to avoid desorption of condensed vapors from the collected particulates and other auxiliary filter and control means are included.
