FIELD: machine building.SUBSTANCE: SCR-system for exhaust gas cleaning feeds fluid to feeder and, therefrom, to dispenser at SCR-system consumption point. Proposed method comprises the stage of continuous determination of aggregate amounts of fluid fed through said dispenser. Necessity in replacement or cleaning of filter unit for said fluid is defined proceeding from said aggregate amounts of batched fluid. Besides, this method comprises the stage of batching of at least the fluid portion fed through the feeder and that of feeding of non-batched fluid back into return flow for it to be fed to said feeder. Invention relates to computer software product including program, code for implementation of proposed process in compliance with this invention. Invention covers also the device and carrier equipped with the latter.EFFECT: decreased risks of filter clogging, higher efficiency of SCR-system.21 cl, 6 dwg |
