It is normal for a car not to generate electricity at idle but to generate when accelerating. Below are the specific details about the car alternator: Working Principle: When the external circuit supplies current to the excitation winding through the brushes, a magnetic field is generated, magnetizing the armature into N and S poles. Maintenance: Regularly clean the accumulated dirt and dust on the alternator's surface to maintain cleanliness and ensure good ventilation. Periodically check the tightness of all fasteners related to the alternator and promptly tighten any loose screws. Function: The car alternator is the primary power source of the vehicle. Its role is to supply power to all electrical devices (except the starter) when the engine is running normally and to recharge the battery.

How to Clean the Throttle Body in a Car?

To clean the throttle body in a car, follow these steps: 1. Turn off the ignition switch and disconnect the negative terminal of the battery; 2. Remove the throttle cable, intake hose, and screws securing the throttle body in sequence; 3. Use a cleaning agent to clean the throttle body, and for areas that are hard to reach, use a cotton swab to wipe. The throttle body is a controllable valve that regulates the air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to perform work. The effects of a dirty throttle body include: 1. Engine shaking during idle; 2. Insufficient power when driving; 3. Increased fuel consumption; 4. The vehicle is prone to stalling; 5. Emissions fail to meet standards.

What is the difference between AMT transmission and AT transmission?

The differences between AT transmission and AMT transmission lie in their transmission forms and functions, as detailed below: Different transmission forms: AT transmission stands for automatic transmission; AMT transmission stands for automated manual transmission. Different functions: AT transmission does not require a clutch for gear shifting; AMT transmission achieves gear shifting through an added microcomputer control system that automatically operates the transmission. Both AT and AMT transmissions belong to the category of automatic transmissions, which are designed to automatically shift gears based on the vehicle's speed and engine RPM, as opposed to manual transmissions. Efficiency differences: AT transmission, due to its reliance on hydraulic torque converter for hydraulic power transmission, has relatively lower efficiency with significant energy loss. Some transmissions now can lock the hydraulic torque converter at high speeds, improving transmission efficiency to a certain extent, but overall, it still falls short of AMT's efficiency. AMT efficiency is equivalent to that of a manual transmission, with high transmission efficiency and minimal power loss. AT transmission is an automatic transmission, with gear positions including P, R, N, D, 2, 1, or L. The advantage of this transmission is its relatively stable technology, while the main drawbacks are higher costs and greater development difficulty. AT transmission consists of components such as the valve body, oil pump, clutch, brake, one-way clutch, diaphragm spring, retaining ring, steel plates, friction plates, large sun gear, small sun gear, planetary carrier, and ring gear. AMT is classified by some manufacturers as an automatic transmission, but strictly speaking, it can only be considered semi-automatic. Cars equipped with AMT no longer require a clutch pedal; the driver only needs to press the accelerator pedal to start and drive the car very simply. This is very important for novice drivers and the overall reliability of the vehicle. Its advantages include simple structure and lower cost, while the main disadvantage is severe gear shift shock. In China, AMT is currently only applied to some A0-level car models. AMT transmission is essentially a manual transmission with automatic clutch and gear shift control functions. Its structure is fundamentally the same as that of a traditional parallel-axis manual transmission, with no essential differences in construction.

What is the Scrap Period for Private Cars?

For 5-seat family cars and 7-seat SUVs, non-commercial small and mini vehicles have no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide them to be scrapped. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial cars, and wheeled special machinery vehicles also have no usage period limit. Commercial vehicles have scrap periods, as follows: Small and mini taxi passenger cars have a scrap period of 8 years, medium taxi passenger cars have a scrap period of 10 years, and large taxi passenger cars have a scrap period of 12 years. Bus passenger cars have a scrap period of 13 years, other small and mini commercial passenger cars have a scrap period of 10 years, and large and medium commercial passenger cars have a scrap period of 15 years. Mini commercial trucks have a scrap period of 8 years, light and large commercial trucks have a scrap period of 10 years. The vehicle scrap process is as follows: The car owner applying for scrap renewal must fill out an "Application Form for Vehicle Change, Transfer, Modification, Suspension, or Scrap Approval" and stamp it with the owner's seal. The registration office accepts the application and issues a "Vehicle Scrap Notice" for vehicles that have reached the scrap period. For vehicles that have not reached the scrap period, after inspection by the vehicle inspection office, if they meet the scrap standards, a "Vehicle Scrap Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company dismantles the vehicle and takes photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner submits the "Change Form", "XX Province Updated Vehicle Technical Appraisal Form", "Scrap Vehicle Recycling Certificate", and vehicle dismantling photos to the vehicle inspection office for verification and signature. The license plates are reclaimed, and the application is submitted for approval according to regulations to complete the scrap registration. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrap vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrap period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of motor vehicle registration, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation registration; (2) The owner must have owned the original vehicle for more than three years.
