Vibration signal total energy comparison of a single-cylinder diesel engine when different diesel-biodiesel fuel blend used at 2000 and 3000 rpms

Abstract

Fossil fuels pollute the air and threaten human health. In addition, fossil fuels are among the causes of global warming. One of the solutions that will reduce these losses is to use biodiesel or biodiesel blend fuel.In this study, biodiesel fuel produced from standard diesel fuel and waste frying oil was mixed with 15%, 30% and 50% by volume, respectively, to obtain B15, B30 and B50 fuel blend. Total energies using the time components exceeding certain threshold of vibrations at 2000 and 3000 RPMs of a single-cylinder diesel engine operating at full load using B0 (pure diesel fuel) and B15, B30, B50 fuel blend obtained were calculated. It was observed that as the amount of additive mixture increased, the total energy values above the threshold increased.
