| Abstract: | A force model of a control valve of injector is set up, and the changes of the fluid damping clearance are investigated on the basis of the results of the computational fluid dynamics (CFD) and the experiments of control valve of injector. Results indicate that a damping clearance of 0.02–0.03 mm between the poppet and the valve guide is the most sufficient to dampen any excessive control valve poppet bouncing. __________ Translated from Journal of Shanghai Jiaotong University, 2006, 40(6): 1031–1034 [译自: 上海交通大学学报] |
