Abstract
The systems and methods described herein beneficially provide an exit gas having a third, relatively low, NO/NOratio that closely approximates the NO/NOratio found in the exhaust of various internal combustion engines. The systems and methods described herein receive a feed gas having a first, relatively high NO/NOratio. The feed gas is apportioned into a first feed gas portion that is passed through a non-thermal plasma generation system to provide an intermediate gas having a second, relatively very low, NO/NOratio and a second feed gas portion having the first NO/NOratio. The intermediate gas and the second feed gas portion are combined to provide the exist gas having the third, relatively low, NO/NOratio. The systems and methods described herein beneficially provide an exit gas having a variable NO/NOratio to simulate exhaust from a variety of internal combustion engines.
