What is Michelin?

Michelin is one of the world's top three tire giants, marketing its products in over 170 countries globally. The Michelin Group has 113,529 employees worldwide, 69 manufacturing plants, and 2 rubber plantations. It produces 190 million tires, 17 million maps, and guides annually. Here are some details about Michelin: Michelin Brand Logo: The Michelin tire logo design somewhat resembles an Egyptian mummy. Although the design does not incorporate excessive texture effects, the Michelin mascot in the foreground forms a striking contrast with the uppercase "MICHELIN" enclosed in a square in the background. The pure tech-blue background further highlights Michelin's technological appeal. Michelin's Business Areas: The Michelin Group's business activities include various tires, mobility assistance systems (such as the PAX system), and travel services (such as Via-Michelin, GPS, travel guides, and maps). Among these, its map and guide publishing division is a leader in the field. The renowned Michelin Guide celebrated its 100th anniversary in 2000.

Is Transmission Fluid the Same as Gear Oil?

Transmission fluid and gear oil are not the same. They differ in viscosity and properties, and must be used correctly without confusion. The specific details are as follows: Transmission fluid, also known as Automatic Transmission Fluid (ATF) or automatic transmission oil, is used as a working medium in vehicle automatic transmissions composed of hydraulic torque converters, hydraulic couplings, and mechanical transmissions. It transmits energy through the kinetic energy of the liquid. Gear oil is primarily made from petroleum-based lubricating oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important lubricating oil. It is used in various gear transmission devices to prevent tooth surface wear, scuffing, sintering, etc., thereby extending their service life and improving power transmission efficiency. Gear oil should have excellent anti-wear and load-bearing properties, as well as appropriate viscosity. Additionally, it should possess good thermal oxidation stability, anti-foaming properties, water separation performance, and rust prevention. Since gear loads generally exceed 490 MPa, and hypoid gear surface loads can reach up to 2942 MPa, extreme pressure anti-wear agents are often added to gear oil to prevent oil film rupture and subsequent tooth surface wear and scuffing. Sulfur-phosphorus or sulfur-phosphorus-nitrogen additives are commonly used. Transmission fluid cannot replace gear oil. Due to its low viscosity and the addition of large amounts of high-boiling-point organic solvents, it cannot be used as a substitute for mechanical lubrication oil.

What Causes the Clicking Sound When Starting a Car and the Engine Not Firing?

The reasons and solutions for a car making a clicking sound but not starting are as follows: The starter motor is faulty and cannot turn the flywheel: When starting the vehicle, check if the starter motor is functioning. The battery is faulty and cannot store power: If you only hear the sound of the starter when trying to start the car, it is likely due to a dead battery preventing the engine from starting. The vehicle's fuel supply system is faulty: Disconnect the fuel line connector on the engine, turn the ignition switch to the position where the dashboard lights come on (without cranking the starter), and observe if fuel flows out. If fuel flows, the fuel supply system is fine; if not, further inspection is needed. The vehicle's ignition system is faulty: Remove one of the ignition high-voltage wires from the engine, insert an old spark plug or another metal rod into the spark plug cap, and place the spark plug body or metal rod near an engine metal part. Start the engine and observe if there is a high-voltage spark. If not, check the ignition system for issues.

Is Low-Speed Jerking in CVT Transmissions Normal?

Low-speed jerking in CVT transmissions is a normal phenomenon. When the vehicle jerks at low speeds, it is caused by the impact force generated by the internal components of the transmission during inertial movement. There is no need to worry about jerking in CVT transmissions as long as the vehicle is properly maintained and used normally. Introduction to CVT Transmissions: CVT, which stands for Continuously Variable Transmission in English, is also a type of automatic transmission. Unlike other AT automatic transmissions that use gears, CVT transmissions can continuously change the transmission ratio to achieve variable speeds. This is done by altering the radii of two pulleys to change the speed ratio. Core Components of CVT Transmissions: From the overall structure of CVT transmissions, it can be understood that the core component is the steel belt. The lifespan of the transmission largely depends on the durability of this belt. Currently, the material commonly used for CVT steel belts is the German Bosch pressure steel belt.

What documents and procedures are required to buy a used car?

Buying a used car requires the following documents and procedures: Documents required for buying a used car: For individuals: ID card; for non-locals who need to register the car locally, a valid temporary residence permit (residence permit) is also required. For organizations: original organization code certificate and official seal. Procedures required for buying a used car: Check if the car is mortgaged or under court seizure; verify traffic light violation records and any unpaid fees; obtain a vehicle transfer agreement from the vehicle management office; complete the change of additional tax certificate; complete the change of road maintenance fee receipt; if there is an insurance policy, complete the transfer procedure. Valid documents required when signing the vehicle transfer contract: Original owner's ID card, new owner's ID card, original/duplicate of vehicle license, purchase tax certificate, vehicle and vessel tax payment proof, motor vehicle registration certificate, motor vehicle criminal inspection report, road maintenance fee receipt, insurance policy/card/invoice. All original documents must be provided, and copies should be retained.

What are the tips for reversing into the garage in Driving Test Subject 2?

Tips for reversing into the garage: After getting into the car, the driver should first adjust the seat and rearview mirrors, fasten the seat belt, then shift the car into reverse gear, release the parking brake lever, and start reversing at idle speed while observing the garage through the right rear window. When the black edge of the right rear window aligns with the right boundary line of the garage, turn the steering wheel steadily to the right until it reaches the limit position. After the car enters the garage, the driver should look back at the left rearview mirror. When the entire left boundary line of the garage becomes visible, immediately straighten the steering wheel. When the left door handle is seen level with the bottom line of the garage in the left rearview mirror, stop the car immediately. Points deduction items for reversing into the garage are as follows: Not following the prescribed route or sequence: deduct 100 points; vehicle body crossing the line: deduct 100 points; failing to reverse into the garage: deduct 100 points; stopping midway: deduct 100 points. Driving Test Subject 2 has a full score of 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For large passenger cars, tractors, city buses, medium-sized passenger cars, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required.
