1. the multi-valve injection method of a carbamide reducing agent is characterized in that:

  • be in series with filter on the pipeline of carbamide reducing agent case, through the pipeline filter of flowing through, the pipeline of the filter of flowing through flow in parallel respectively is c to liquid under pressure-driven 0Electromagnetic Flow control valve or electromagnetic proportional valve, the number in parallel of Electromagnetic Flow control valve or electromagnetic proportional valve is 6 ~ 9;

    The flow through liquid of Electromagnetic Flow control valve or electromagnetic proportional valve, or separately, or 2 start simultaneously, or 3 startups simultaneously, or 4 startups simultaneously, or 5 startups simultaneously, or 6 startups simultaneously, or 7 startups simultaneously, or 8 startups simultaneously, or 9 startups simultaneously, be pooled to pressure maintaining valve, be transported to urea reducing agent nozzle from pressure maintaining valve then, under air is auxiliary, be ejected in the outlet pipe.
