To disconnect the negative terminal of a car battery, follow these steps: 1. First, open the two fastening buckles of the thermal insulation cover, lift the red and black insulating caps on the positive and negative terminals, and locate the tightening nut of the battery's negative terminal. 2. Use a wrench to loosen the tightening nut of the negative terminal, then gently pry open the fastening block with a flat-head screwdriver. At this point, you can directly pull out the negative terminal connector. 3. Note: During the removal process, always follow the sequence of "negative terminal first, then positive terminal" (the opposite of the installation sequence). If done in reverse, it may cause a short circuit in the car battery, and in severe cases, it could lead to sparking.

What to Do When Feeling Lack of Power After an Oil Change?

If you experience a lack of power after changing the engine oil, you can try the following solutions: 1. Replace the oil filter: A faulty or clogged oil filter can cause issues, so it's generally recommended to replace the oil filter along with the new oil. 2. Clean the engine lubrication system during the oil change: If the engine lubrication system hasn't been cleaned for a long time, deposits can accumulate. Changing the oil may dislodge some impurities, suspending them in the oil and clogging the filter, leading to power loss. 3. Pay attention to the oil quantity when adding oil: Adding too much or too little oil can both cause power issues, which should improve after the second oil top-up.

Is there a difference between CVT and ECVT?

The following are the specific differences between CVT and ECVT: 1. Structure: The structure of CVT mainly consists of two sets of pulleys and a transmission belt, oil pump, torque converter, actuator, sensors, control computer, etc. The composition is relatively complex, and the steel belt has limited torque capacity, so it is generally only used in small vehicles as a transmission system. ECVT includes complex mechanisms such as clutches, torque converters, or gear shaft sets found in traditional transmission systems, and is composed of a set of planetary gears and two motors. 2. Working principle: In CVT technology, Motor 2 is responsible for starting, low-speed driving, and hybrid driving; Motor 1 is mainly responsible for starting the engine and generating electricity, and the engine does not directly drive the wheels in most cases. The engine is connected to the planetary carrier, Motor 1 is connected to the sun gear, Motor 2 is connected to the outer ring gear, and the outer ring gear is connected to the power output shaft. ECVT not only transmits power but also couples the energy of the engine and motor to achieve power output. It is actually a power combination system, specifically designed for the power distribution mechanism of hybrid models. 3. Power solution: CVT refers to the ordinary mechanical continuously variable transmission. ECVT is the electric transmission mechanism of Toyota's strong hybrid solution, which can achieve electric drive, continuously variable transmission, and energy recovery.

Is a Physical Examination Required for a Driver's License?

Obtaining a driver's license requires a physical examination. The examination primarily includes checks for vision, height, color blindness, hearing, as well as the upper limbs, lower limbs, torso, and feet to identify any abnormalities. The physical examination items for a driver's license include: 1. Height: Applicants for large passenger vehicles, tractors, city buses, large trucks, and trolleybuses must be at least 155 cm tall. Applicants for medium-sized passenger vehicles must be at least 150 cm tall. 2. Color Vision: Applicants must not have red-green color blindness. If they do, they are immediately disqualified, and other tests are unnecessary because recognizing traffic lights is essential on the road. 3. Hearing: Applicants must be able to hear a tuning fork from 50 cm away and distinguish the direction of the sound source. Failure to do so results in disqualification. 4. Vision: Applicants for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or trams must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart. For other vehicle types, uncorrected or corrected visual acuity must be at least 4.9 on the logarithmic visual acuity chart.
