Experimental Study of Urea-SCR System under Open-loop Control Strategy

  Open-loop control strategy of SCR urea injection system for MD/HD vehicle diesel engine is established firstly in this paper.Then the emission test is performed for a domestic diesel engine in test bench.Test results show that NOx emissions of ESC and ETC are much lower than the limit values of National-V emission regulation under a simple injection strategy.The results also show that the urea solution consumption accounts for only 5.8% of the fuel consumption.Whats more, the tests have been accumulated for achieving accurate matching between urea injection and diesel engine.
