The torque specification for the main bearing cap bolts of an Audi engine is 100N.m. Automotive main and connecting rod bearings: In automobiles, the main and connecting rod bearings (commonly referred to as "big and small bearings") are actually journal bearings. They are categorized into crankshaft bearings and connecting rod bearings, manufactured from high-hardness wear-resistant steel, and consist of upper and lower halves. These bearings are fitted at the junctions between the crankshaft and engine block, as well as between the connecting rods and crankshaft. The critical feature of these bearings lies in their contact surfaces, which are coated with a specialized wear-resistant material. This coating isn't an extremely hard substance—it's actually soft enough to be scratched with a fingernail—yet it achieves nearly 100% precision in contact with the crankshaft. These bearings play an indispensable role in ensuring smooth engine operation without vibration, regardless of whether the engine is running at high or low speeds. Engine: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. This category includes internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines and steam engines), jet engines, electric motors, among others. For instance, internal combustion engines typically transform chemical energy into mechanical energy. The term "engine" can refer either to the power generation unit alone or to the entire machine including the power unit (examples: gasoline engines, aircraft engines). The engine was first developed in England, hence the concept originates from English, with its original meaning referring to "a mechanical device that generates power."
