Latest Patents

Kunkel holds a patent for a "System and method for dispensing an aqueous urea solution into an exhaust gas stream." This invention involves an aqueous urea dosing system that utilizes a first tube to convey the urea solution to a small mixing chamber. Compressed air is continuously conveyed through an annular space between the outer surface of the first tube and the inner surface of a second tube. The mixing chamber is strategically positioned between the distal ends of both tubes. The urea solution is discharged into the mixing chamber and subsequently into the exhaust gas in a series of discreet pulses. The width and period of these pulses are controlled by a pulse-width-modulated flow control valve, which is spaced from the exhaust gas.
