Abstract

See full text

Various example embodiments relate to a system that includes a nozzle. A dosing line is connected to the nozzle and a fuel dosing module. The fuel dosing module is in fluid communication with the dosing line and includes an outlet in fluid communication with the dosing line. An air inlet is positioned upstream of the outlet and is configured to receive air. A fuel inlet is positioned upstream of the outlet and is configured to receive fuel. A fuel valve is positioned upstream of the outlet and downstream of the fuel inlet and is configured to control the flow of fuel. The fuel dosing module is configured to combine the fuel and the air upstream of the outlet and downstream of the fuel valve to generate an air-fuel fluid, wherein the air-fuel fluid removes particles from the nozzle.
