Comparative analysis of the internal combustion engine block vibration with gasoline and ethanol fuel
Ethanol and gasoline are widely used with fuels in Otto cycle engines. These fuels have different heating power and octane number and the engine behaves differently depending on the type of fuel used. The objective of this study is to measure, compare and investigate the factors that affect the block vibration of an internal combustion engine as a function of the fuel used ethanol or gasoline. The experiment consisted of instrumenting the side of the engine block with an accelerometer to measure the level of vibration intensity of the engine running on a bench dynamometer varying engine speed and load conditions. The results showed that the engine vibration level increases with the increase in engine speed and load. The highest level of vibration was achieved in the region of maximum torque and maximum pressure combustion. The combustion process is mainly responsible for the highest level of vibration achieved with ethanol. In all operating conditions the vibration level of the engine block was higher as ethanol. On average, the longitudinal, vertical and transverse engine vibration was 3%, 31% and 56% higher in the engine running on ethanol compared to the engine using gasoline. This research is important because it correlates the vibration level of the block of an internal combustion engine as an engine combustion process fueled with ethanol and gasoline.
