A method for improving the reduction of nitrous oxides in motor vehicle exhaust gases has a jet delivering a urea solution connected to a high tension positive electrode and an electrode at a negative potential

摘要

The vehicle exhaust gas (34) is emitted from the tube (25) while a urea solution (16) is injected as droplets (16) with a high tension (22) positive charge and is broken down into a fine mist of droplets (18) by a high tension negative (23) electrode (20).
