How many hours are required for Subject 3 training?

Subject 3 requires 12 hours of theoretical training and 24 hours of practical training, totaling 36 hours. Theoretical Training: The maximum daily theoretical training is 4 hours; if the training time exceeds 4 hours, it will be counted as 4 hours. Online Requirements: To ensure students are actively learning, if no operation is performed within 5 minutes, the system will automatically log out and stop timing. Completion Requirements: After completing the training, please click the "Exit" button in the lower left corner of the pop-up window. Do not close the pop-up window directly, otherwise, the account may be locked for 10 minutes and unable to log in.

Is a tire pressure of 1.9 normal in winter? Do I need to add air?

Winter tire pressure of 1.9 bar is too low. In winter, it is recommended to slightly increase the tire pressure by about 0.2 bar based on the standard tire pressure for your car. When the car is cold, a front tire pressure of 2.2-2.3 bar and a rear tire pressure of 2.4-2.5 bar are within the normal range. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Normal winter tire pressure: In winter, adjust the tire pressure slightly higher by about 0.2 bar based on the standard tire pressure for your car. Normal summer tire pressure: Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.

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.
