Abstract

Electric-powered oil extraction through a motorcycle engine’s service opening can simplify routine maintenance, but performance depends on viscous-fluid behavior, suction-line geometry, and the pump operating point. This study compared nominal nylon hose diameters of 6, 8, and 10 mm at a common length of 1.8 m and a fixed extracted oil volume of 780 mL. Extraction time and current were recorded at 220 V, while flow rate, cycle energy, hydraulic power, and a system-level hydraulic-to-electrical power ratio were recalculated for consistency. The 8 mm hose produced the shortest extraction time (44 s), highest flow rate (1.773 × 10⁻⁵ m³/s), and lowest corrected cycle energy (3.227 Wh). With the recorded 0.666 m total head, hydraulic power was 0.1066 W and the apparent hydraulic-to-electrical ratio was 0.0404%. Relative to the 6 and 10 mm hoses, the 8 mm configuration reduced extraction time by 30.2% and 33.3% and energy use by 34.5% and 28.6%, respectively. The reported oil-recovery ratio was 97.5%. The 8 mm hose therefore provided the best observed performance for this prototype, although confirmation requires replicate-level statistics, controlled oil temperature and viscosity, direct differential-pressure measurement, and true electrical-power measurement.
