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).
