摘要: NOx reduction experiments were conducted by direct injection of urea into a diesel fueled, combustion-driven flow reactor which simulated single engine cylinder (). tests carried out over wide range air/fuel ratios (A/F=20-40) using an initial level 530ppm, and for normalized stoichiometric reductant to (NSR) 1.5 4.0. The results show that effective with occurred temperature 1100 1350K. increased increasing NSR values, about 40%-60% was achieved NSR=1.5-4.0. Most the within head section (residence time ) exhaust pipe promoted further substantial (5%-30%) without shifting windows. Diesel fuel found enhance more than , finally practical implications are discussed.
