Abstract
A method of removing sulfur from a lean NOx trap of a mild hybrid vehicle while the vehicle is stationary is disclosed, the method comprising connecting an electrical system of the vehicle to a large capacity external battery, operating an integrated starter generator driven by an engine of the vehicle as a generator to load the engine thereby allowing the engine to be operated at a higher torque level and rich of stoichiometric and storing the electrical energy produced by the integrated starter generator in the large capacity battery during the time period required for the removal of sulfur from the lean NOx trap.
