The fuel pressure regulating valve of the BMW 5 Series is located under the hood, at the upper left corner of the engine. Introduction to Engine Oil: Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions for the engine, including lubrication and friction reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. It is often referred to as the 'blood' of the car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance of the base oil, providing additional characteristics. Additives are a crucial part of the lubricant. Classification of Engine Oil: Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic oils. Oil Control Valve: The oil regulating valve is designed to regulate and prevent excessive pressure in the engine lubrication system. It consists of the valve body assembly and the actuator assembly (or actuator system).
