BMW vacuum pump oil leaks should not be left unrepaired. Oil leakage is caused by damage to the engine cylinder gasket, oil pan gasket, sealing rings, or front and rear crankshaft oil seals, camshaft oil seals, or loosening of fastening screws. Oil leaks must be repaired promptly; otherwise, it can lead to insufficient engine oil, resulting in engine damage. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is hailed as the 'blood' of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricating oil.

What is a torque converter composed of?

A torque converter is composed of a pump impeller, turbine, and stator. The pump impeller is connected to the drive shaft, and its working principle is: when the engine is running, it drives the torque converter's housing and pump impeller to rotate together. The hydraulic oil inside the pump impeller, under the action of centrifugal force, flows from the outer edge of the pump impeller blades to the turbine, then along the turbine blades to the stator, and finally back to the inner edge of the pump impeller blades through the stator blades, forming a circulating fluid flow. The torque converter is a component that transmits power through the high-speed movement of liquid. Its working characteristics are: the speed and torque at the input end are basically constant, while the speed and torque at the output end can be greater than, equal to, or less than those at the input end. Moreover, the relationship between the output speed and output torque can automatically and continuously adjust according to the load of the driven working machine.
