摘要: The wide use of fossil fuel in internal combustion engine cause reduction these resources and also increase greenhouse gasses environmental pollution, for conquering problems, so many researches have done finding the renewable herbaceous fuel. Between different kinds fuel, biodiesel seems to be appropriate because nonexistence air pollutions existence similar trait with diesel In this research, vibration 13hp power tiller 5 levels speed 6 consuming blends investigating behavior transmissibility. Results showed that transmissibility is decreased by increasing speed. maximum happened B20 B5 minimum it B15 D respectively. Also observed amount acceleration longitudinal axis much more than other two axes. value, frequency range 8 100 Hz was higher a dangerous hand-arm transmission total weighted has value at 20, 31.5, 40 63 amplitude reach up 12.6, 18.6 m/s2 best are 1400, 1600 2000 rpm, Engine using appropriate.
