Hybrid Technology For Lean Nox Trap And Particulate Filter Regeneration Control

View page
US Patent:
7621120, Nov 24, 2009
Filed:
Jun 15, 2006
Appl. No.:
11/454110
Inventors:
Andrew C. Matheaus - San Antonio TX, US
Ryan C. Roecker - San Antonio TX, US
Assignee:
Southwest Research Institute - San Antonio TX
International Classification:
F01N 3/00
US Classification:
60274, 60280, 60285, 60286, 60295, 60301, 180 651, 180 653, 180 654, 180 656
Abstract:
A method for the use of hybrid technology to control lean NOx trap (LNT) and particulate filter regenerations using an electric motor wherein for the LNT (a) the electric motor is adapted to absorb torque excursions of the engine during regeneration of the LNT, (b) wherein the electric motor is adapted to add torque to thereby reduce the air required in the engine and to thereby reduce the amount of fuel needed to regenerate the LNT, or (c) both (a) and (b), or wherein for the particulate filter the electric motor is (a) adapted to load the engine to thereby increase the exhaust temperature to thereby facilitate regeneration of the particulate filter, (b) adapted to use a power source for the electric motor to power an electrically powered particulate filter regeneration unit to thereby facilitate regeneration of the particulate filter, or (c) both (a) and (b).

US Patent:
20040060284, Apr 1, 2004
Filed:
Oct 1, 2002
Appl. No.:
10/261128
Inventors:
Charles Roberts - San Antonio TX, US
Andrew Matheaus - San Antonio TX, US
David Branyon - San Antonio TX, US
Rudolf Stanglmaier - San Antonio TX, US
Lee Dodge - San Antonio TX, US
Thomas Ryan - San Antonio TX, US
Daniel Stewart - Helotes TX, US
International Classification:
F01L001/34
F01N003/00
US Classification:
060/284000, 123/090150
Abstract:
A method for controlling the temperature and/or space velocity of exhaust gas passing through an aftertreatment device disposed in the exhaust system of a diesel engine provides an optimal environment for efficient conversion of NOx and undesirable emissions during transient and steady state engine operation. The method includes controlling intake and/or exhaust valve timing, either singly or in combination with fuel injection timing and selective individual cylinder cutout, in response to sensed engine operating parameters.
