Egr Pulse Attenuation

US Patent:
20090139216, Jun 4, 2009
Filed:
Nov 30, 2007
Appl. No.:
11/948597
Inventors:
Laurentiu Dobrila - Cedar Falls IA, US
International Classification:
F02B 27/04
US Classification:
60312
Abstract:
A pulse attenuator for the EGR line of an internal combustion engine in which a main flow path has a pair of branch flow paths extending from the upstream portion of a venturi. The branch flow paths have a precisely determined length so as to reintroduce pulses back to the main flow path in a way that smoothes the flow. The pulses may be reconnected to the main flow path downstream of the point at which they are extracted or at the same point. The length of the branch passages may be different to provide attenuation of pulses at different engine rpms.
