Where is the oil-water separator located in a car?

[Elsie]

The oil-water separator is generally installed at the lowest point of the pipeline or at the working inlet (with the oil filter in front, followed by the water filter). When compressed air containing a large amount of oil, water, and solid impurities enters the separator, it swirls downward along the inner wall. The resulting centrifugal force separates the oil and water from the air stream, causing them to flow downward along the wall to the bottom of the oil-water separator. The oil is then finely filtered by the filter element. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber in the engine. It is often referred to as the 'blood' of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives compensate for and improve the shortcomings of the base oil, imparting new characteristics. Additives are an essential part of the lubricant.
