Vibration Analysis of Diesel Engine Fueled with Diesel and Fish Oil Blends at Different Loading Conditions

Diesel engine is a very important prime mover and to run diesel engine fuels are required. Due to the shortage of conventional fossil fuels there is need to use alternative fuels extracted from waste like fish oil which contains discarded body parts of fish. To check the performance of internal combustion engine vibration analysis plays an important role. In this paper using lab view setup vibration signals are collected through data acquisition system by attaching accelerometer on cylinder head of internal combustion engine by considering statistical factors like kurtosis, crest factor, RMS, skewness and FFT. By considering these factors we compare vibrating signals for diesel-fish oil blends viz, B1 (15% fish oil + 85% diesel), B2(30% fish oil + 70% diesel) and B3(45% fish oil + 55% diesel). The experimentation was carries out at different loading condition, load 0kg to 12kg in step of 3 in three different directions for cylinder head. After experimentation it is concluded that use of diesel-fish oil blends in internal combustion engine will reduce the vibration as compare to no blend condition, where kurtosis isa better criterion for vibration analysis.
