Self-sufficient system for NOx reduction

This paper describes a SCR system which is being developed for using with the diesel engines. Unlike the commercial products this system has not to be connected with the electrical control units or sensors of the target engine. It means the system is not dependent on the vehicle type. The goal of this project is to develop a self-sufficient system for the reduction of nitrogen oxides. This feature enables using the same system in wide range of projects, including retrofitting. It also describes whole hardware principle and the interconnection between modules. Additionally the basic behavior of the catalytic convertor is described and demonstrated by the results of several tests on the test bench.
