Consumption, level of particulate matter emissions and engine temperature were also analyzed. The experiments were performed considering noninvasive tests in a diesel engine, taking into account three different speeds: 800 rpm, 1800 rpm and 3600 rpm. Results showed that the engine energetic loss from vibration signals collected allowed a quantitative assessment of how each fuel influenced the engine vibration level. In the three analyzed speeds, B8 diesel fuel showed be more energetic when compared to B100 biodiesel fuel. Although the consumption using B100 biodiesel fuel presented higher values than B8, the level of particulate matter emissions was lower than commercial diesel B8. It was also noted that the vibration increased in both cases when the engine speed increased. B8 diesel presented a total vibration varying according to speeds range, from 4.5% to 21% higher than B100 biodiesel. Therefore, the dissipated vibration energy using B8 diesel was higher (10% to 45%) than B100 biodiesel. It is concluded that combustion is one of the item that generates higher level of vibration in diesel engines and it depends on the kind of fuel used.
