Method and system for reduction of NOx in automotive vehicle exhaust systems

摘要

A method and system for reducing the amount of NOx in an automotive vehicle combustion exhaust gas are disclosed. Accordingly, the system includes a first converter for forming aldehyde in a tributary fluid that includes fuel from the fuel tank of an automotive vehicle. Once the aldehyde is formed, the tributary fluid is combined with combustion exhaust of the vehicle to form an aldehyde/exhaust admixture. Thereafter, a second converter of the system is used to reduce NOx in the aldehyde/exhaust admixture to N2 gas and O2 gas.
