| Abstract: | The structure of fuel rail assembly and the causes of fuel injection noise are analyzed in detail.Various measures for reducing the noises of injector and fuel rail are targetedly proposed.In a real example,by adopting a improving scheme of reducing the mass of needle valve and changing the cross section and wall thickness of fuel rail,the fuel injection noise is reduced by 7.4dB(A),solving the problem of high injection noise. |
