| Abstract:Water hammer pressure wave occurring in the high pressure common rail system would influence the accurate control of fuel volume of multi-injection. The T resonance filter for high pressure common rail systems were designed to solve this problem. Test results show that with the T resonance filter，the amplitude of water hammer pressure wave, as well as the fluctuation of injected fuel are significantly reduced, the maximum attenuation rate of water hammer pressure wave has reached 17, meanwhile, the maximum fluctuation rate is reduced by 19%. Besides these favorable results, the T resonance filter features simple structure, small size and high efficiency. |
