Latest Patents

Hagin's latest patents include a "Dosing module for dosing an urea-based reducing agent into a gas exhaust stream." This invention relates to a dosing module designed for injecting an urea-based reducing agent into the exhaust gas stream of a combustion engine, specifically for after-treatment systems such as SCR or SCRT systems. The module features a housing that extends along a longitudinal axis and includes an inlet opening for conveying exhaust gas. The design incorporates dosage means for accurately dosing the reducing agent. The inlet opening is annular and inclined, generating an exhaust gas inlet jet. Additionally, the dosage means create a coaxial urea-based reducing agent spray within the housing.

Another significant patent is the "Method for dosing an urea-based reducing agent into a gas exhaust stream." This method outlines a process for dosing an urea-based reducing agent into the exhaust gas stream generated from a combustion engine. The gas is conveyed into a dosing housing along a longitudinal axis, utilizing an annular inlet jet that is inclined relative to this axis. The urea-based reducing agent is injected through a spray that is also coaxial to the housing's axis.
