| Abstract: | Using finite element analysis,the structural and the reliability analysis of the sealing element in electronically controlled high pressure common rail injector is performed.The results show that the sealed reliability of the sealing element mainly depends on the fuel pressure,the physical capability of sealing element,the radial clearance and the eccentricity of the coupled part,and the fuel pressure is the most important factor.Moreover,the analysis method is effective for similar researches and the results offer an academic method to improve the sealed reliability of injector. |
