Why does the UY125 need an oil-water separator?
2 Answers
The functions of an oil-water separator are as follows: 1. Components: The oil-water separator primarily uses the density difference between water and fuel to remove impurities and water through the principle of gravity sedimentation. It also includes internal components such as diffusion cones and filter screens. 2. Filtration: The oil-water separator has additional functions, such as preheating the fuel to prevent wax formation and filtering out impurities. 3. Extended lifespan: It is a type of fuel filter, mainly designed to remove water from diesel, thereby reducing injector failures and extending the engine's service life. 4. Oil-water separation: The oil-water separator can only separate water from the fuel, removing water from the oil, which has a certain effect on improving the engine's oil consumption.
After installing the oil-water separator on my UY125, the most noticeable improvement is the reduced engine coughing. When using low-quality gasoline, water contamination is common, especially during the rainy season in southern regions where condensation forms in gas station storage tanks. This compact device uses centrifugal force to separate water and impurities into a transparent reservoir at the bottom. Simply open the valve periodically to drain the contaminated liquid. Last week, I drained about half a cup of murky fluid – imagine that going straight into the engine, causing anything from rough idling to spark plug corrosion and seizure. The most pleasant surprise was the 0.3L/100km fuel consumption reduction, as water vapor no longer interferes with combustion chamber ignition efficiency. I highly recommend this for riders who frequently take long trips – it's ten times cheaper than replacing an entire EFI system.
