Latest Patents

Fuquan Zhao holds a patent for a "Method and apparatus for supplying a reductant to an engine exhaust treatment system." This invention provides a vaporized reductant to an engine exhaust stream, particularly useful in regenerating a nitrous oxide absorber in Diesel engine exhaust treatment systems. The method involves fueling the Diesel engine with a mixture of Diesel oil and an alcohol, such as methanol. The alcohol vaporizes in the fuel tank or is forced to vaporize through a heat exchanger. The vapor is stored in a canister for selective injection into the exhaust stream upstream of the adsorber. This process allows the alcohol to thermally decompose, generating sufficient hydrogen and carbon monoxide to regenerate the adsorber.
