What does TC skeleton oil seal mean?

TC oil seal is a mechanical component used to seal oil (oil is the most common liquid substance in the transmission system, and it also generally refers to liquid substances). It isolates the parts that need lubrication in the transmission components from the output parts, preventing the leakage of lubricating oil. Additional information: 1. Meaning of oil seal: Oil seal (oil-seal) is the customary term for general sealing components, simply put, it is the sealing of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and it also generally refers to liquid substances). It isolates the parts that need lubrication in the transmission components from the output parts, preventing the leakage of lubricating oil. The sealing components used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. 2. Representation form: The representative form of oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber. Generally, when people refer to oil seals, they often mean this type of TC skeleton oil seal.

Where to Find the Engine Number of a Car?

Locating the engine number: The engine number can be found on the outer surface of the engine block, the vehicle's registration certificate, the motor vehicle registration card, the purchase invoice, the factory certificate of compliance, the operating permit for commercial vehicles, the vehicle purchase tax payment certificate, the public security registration record, the vehicle insurance card, the B-pillar nameplate of the motor vehicle, and the actual engine (usually on the engine nameplate). The engine number is like a person's ID number, representing each vehicle and storing crucial information about it. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or company practices, and the engine's attributes. It indicates information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the professional manufacturer's name, model, and production number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specification and size of the engine within the manufacturer's lineup, and multiple engines can share the same model. The engine number, however, is the production number of the engine, unique to each individual engine. Composition of the engine number: Prefix: Includes product series code, generation symbol, and regional or company code, selected by the manufacturer as needed but must be approved and recorded by the industry standardization unit. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Suffix: Comprises symbols for structural features and usage characteristics. End: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same series, the manufacturer selects an appropriate symbol, which may be separated from the suffix by a hyphen (-).

Will the score be uploaded if not signed for Subject 2?

If the score for Subject 2 is not signed, it will not be uploaded. Without a signature, the examination process is not fully completed, and the score will not be recorded. Below is additional information: 1. Examination Content: Subject 2 is part of the motor vehicle driver's license assessment, referred to as the field driving skills test. The test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curved path. 2. Test Items: The examination includes pole parking, stopping and starting on a slope, parallel parking, crossing a single-plank bridge, driving on a curved path, turning at a right angle, passing through a width-restricted gate, navigating continuous obstacles, driving on undulating roads, making a U-turn on a narrow road, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rainy conditions, slippery roads, and emergency handling.

What is the Difference Between SUV Tires and Sedan Tires?

Introduction to the differences between SUV tires and sedan tires: 1. Appearance: SUV tires are larger, wider, and have deeper grooves and a higher aspect ratio compared to sedan tires. Sedan tires are primarily designed for urban roads or highways, focusing on comfort, handling, and safety. As a result, sedan tires have a softer carcass, finer and simpler tread patterns, with several longitudinal grooves for water drainage. 2. Internal structure: SUVs have a higher center of gravity, which means the tires experience greater lateral and longitudinal forces during turns and braking. The design of the reinforcement ribs also differs significantly from sedan tires. SUV tires feature rigidly connected reinforcement ribs on the outer rubber blocks, which help suppress deformation, distribute stress across individual blocks, effectively reduce braking distance, and prevent skidding during turns.

What type of engine oil is suitable for BYD Song?

BYD Song Max is equipped with a 1.5L turbocharged engine, which requires either 5W30 or 0W30 full synthetic engine oil. Additional information: 1. Function of engine oil: Engine oil is an essential component that every car owner interacts with daily. It plays a crucial role in the engine's operation, often referred to as the "blood" of the engine. Without oil, the engine cannot function properly. Beyond lubrication, engine oil performs multiple functions including cleaning, sealing, buffering, rust prevention, and heat dissipation. 2. Winter recommendation: During winter, 0W oil is recommended due to its superior low-temperature protection properties, which help reduce engine wear. The number following "W" indicates the oil's high-temperature viscosity - higher numbers represent greater viscosity. When selecting engine oil, it's important to consider both your vehicle's engine technical specifications and your driving habits. Most turbocharged engines can use either 30 or 40 viscosity oil. Horizontally opposed engines typically require 20 or 30 viscosity oil, while most naturally aspirated engines can use 20 viscosity oil. It's crucial to choose oil with appropriate viscosity - neither too high nor too low.
