Latest Patents

One of Shouxian Ren's latest patents involves a method for de-sulfurizing a NOadsorber catalyst without significantly increasing the temperature of exhaust gases leaving the engine exhaust manifold. This is achieved by utilizing a diesel oxidation catalyst positioned between the exhaust manifold and the NOadsorber catalyst. This setup elevates the exhaust gas temperature entering the NOadsorber catalyst to a suitable de-sulfurizing temperature through the control of specific aspects of engine operation.

Another significant patent is a soot burn-off control strategy for a catalyzed diesel particulate filter (DPF). This control system comprises three sections: a favorable-condition-based control section, a regular control section, and a regeneration termination control section. The first section initiates regeneration when the actual soot loading of the DPF becomes sufficiently large. The second section initiates regeneration under favorable engine operating conditions when soot loading is less than the mandatory amount. The third section terminates regeneration when soot loading is reduced to a minimum amount or when conditions for continuing regeneration become unfavorable. This innovative approach can lower the average amount of trapped soot in the DPF, thereby reducing the average back-pressure on the engine.
