Claim 16:
17. A fuel dosing module in fluid communication with a dosing line, the fuel dosing module comprising:
an outlet in fluid communication with the dosing line;
an air inlet positioned upstream of the outlet, the air inlet configured to receive air;
a fuel inlet positioned upstream of the outlet, the fuel inlet configured to receive fuel;
a fuel valve positioned upstream of the outlet and downstream of the fuel inlet, the fuel valve configured to control a flow of fuel; and
a control module operably connected to the fuel valve, wherein the control module is configured to control the fuel valve between a dosing state, a purge state, and a cleaning state, the control module configured to open the fuel valve to cause fuel flow through the dosing line in the dosing state, the control module configured to close the fuel valve during the purge state to purge the fuel from the dosing line during the purge state, and the control module configured to oscillate the fuel valve to combine the fuel and the air upstream of the outlet and downstream of the fuel inlet to generate an air-fuel fluid during the cleaning state, wherein the air-fuel fluid removes particles along the dosing line, the control module maintaining an air valve open during transitions between the cleaning state and the purge state.
