Location of oil-water separator of old BMW 525 bonnet waste valve in 2006

In 2006, the old BMW 525 bonnet waste gas valve oil-water separator was on the vacuum tube. On the one hand, it is an oil-water separator for the exhaust gas discharged from the crankcase, from the crankcase to the intake pipe in front of the throttle valve, and on the other hand, it is an oil-water separator from the valve cover vacuum pipe and from the valve cover to the intake pipe. Vehicle oil-water separator is an instrument for separating oil and water, which is mainly divided into water separator in oil and oil separator in water in mechanism.

Working principle of oil-water separator of old BMW 525 bonnet waste valve in 2006

After the jet fuel enters the filter separator, it is first collected in the aluminum tray, and then dispersed into the coalescing filter element from the inside out. Solid impurities are filtered by the filter layer, and emulsified oil and water are separated by the demulsification layer. Step 3, the tiny water droplets are aggregated into large water droplets by the aggregation layer and settled in the water collecting basin. Then, the small water droplets that do not coalesce in time are further separated by the water repellent effect of the separation filter element and settled in the settling tank, and discharged by the drainage valve. Clean fuel is collected in the secondary tray through the separation filter element.
