What materials are required for vehicle inspection in 2021?

2021 vehicle annual inspection requires the following materials: motor vehicle license, identity proof, compulsory traffic accident liability insurance certificate, motor vehicle safety technical inspection certificate (except for exempt vehicles), and vehicle and vessel tax payment or tax exemption certificate. The inspection frequency for different vehicle types is as follows: 1. Non-operational small passenger vehicles: inspection every 2 years for the first 6 years, then annually from the 7th to the 15th year, and every 6 months after 15 years. 2. Non-operational medium and large passenger vehicles and trucks: annual inspection for the first 10 years, then every 6 months from the 11th year. 3. Operational passenger vehicles: annual inspection for the first 5 years, then every 6 months from the 6th year.

What do the first, second, third, and fourth gears mean?

Here is an introduction to the gears of a manual transmission car: 1. First gear: The starting gear, used when the car begins moving from a stop. Another meaning of the starting gear is that it is only used for starting. 2. Second gear: The driving gear, used when the car is moving at low speeds. 3. Third gear: The acceleration gear. From this gear onwards, you can use the throttle to accelerate, increasing the car's speed to a certain level. 4. Fourth gear: The medium-high-speed driving gear. On most city roads, except for elevated roads, this is generally the highest gear used, typically when the vehicle speed is maintained around 60-70 km/h. 5. Fifth gear: The high-speed gear. Used only on elevated roads, highways, etc., generally when the speed is 80 km/h or above. 6. R gear: The reverse gear, used when reversing the car.

Should the Negative Terminal of the Car Battery Be Disconnected When the Car Is Not Used for a Long Time?

When a car is not used for a long time, the negative terminal of the battery should be disconnected. The reasons are as follows: 1. This is to prevent the battery from draining. 2. Generally, if the car is not used for more than a month, the negative terminal of the battery should be disconnected; if the period is not very long, it is not necessary to disconnect the negative terminal. Information about car batteries is as follows: 1. Car battery (Car-battery): Also known as a storage battery, it is a type of battery that works by converting chemical energy into electrical energy. 2. Classification: Batteries are divided into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. 3. Working principle: During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, the lead metal acts as the negative terminal, undergoing oxidation to form lead sulfate; lead dioxide acts as the positive terminal, undergoing reduction to form lead sulfate. When charging with direct current, lead and lead dioxide are generated at the respective terminals. After removing the power source, the battery returns to its pre-discharge state, forming a chemical battery.

How to Handle Traffic Violations with 0 Points and 0 Fine?

You need to bring your vehicle license and driver's license to the traffic police platform to receive a ticket for handling the vehicle violation, but no fine is required. This serves as a warning from the traffic department to remind drivers not to make the same mistake again. If left unhandled, the vehicle will not pass the annual inspection. Below are the methods for handling traffic violations: 1. Online Processing: Violating vehicles can use a mobile APP violation handling software, bind their vehicle information, and check their vehicle violation status at any time. They can directly handle the violation online without going to the vehicle management office, which is very convenient and saves time and effort. 2. Bank Processing: If it is an on-site violation penalty ticket, the owner needs to go to the bank to pay the fine as soon as possible. It does not require the owner to go in person; as long as someone pays the fine in the end, it is acceptable.

Reasons for Rapid Rise in Car Engine Temperature

Here are the specific reasons for rapid engine temperature rise: 1. Insufficient coolant: Coolant leakage or low coolant level will cause engine temperature to rise. In this case, check the coolant level and top up if necessary. Recheck after a few days to see if the level drops significantly, and locate any leaks if present. 2. Cooling fan malfunction: During high-speed operation, heat cannot be effectively transferred to the antifreeze, affecting heat dissipation and causing antifreeze temperature to rise, potentially leading to boiling issues. 3. Water pump failure: Common pump failures include seized bearings or damaged impellers. While bearing seizure is rare, impeller damage (such as cracks or detachment from the pump shaft) can slow coolant circulation, easily causing engine overheating. 4. Thermostat malfunction: The thermostat automatically adjusts the amount of water entering the radiator based on coolant temperature, altering the circulation range to regulate the cooling system's capacity and maintain proper engine operating temperature. A faulty thermostat may prevent the cooling system from entering full circulation mode, resulting in elevated water temperature.

Where is the car air conditioning cooling button located?

The blue button on the left side of the car represents the air conditioning cold air. Below are detailed introductions to the components of the car air conditioning system: 1. Air conditioning pressure sensor: Usually installed after the dryer, it is used to detect the hydraulic pressure of liquid refrigerant flowing through the expansion valve. Three wires: detect high pressure and low pressure. When a car collision causes refrigerant leakage and compressor oil loss, to prevent compressor damage due to lack of oil, once low pressure is detected, the compressor power is quickly cut off. When high pressure is detected, the compressor power needs to be reduced to avoid wasted work. 2. Air conditioning temperature sensor: Usually installed inside the temperature sensing package, it is the evaporator temperature sensor. When the temperature drops to a certain level, the compressor needs to be shut down. Further cooling would cause frosting, eventually leading to ice blockage. 3. Air conditioning compressor relay: Usually installed on the compressor, it is used to control the compressor's start, stop, and power switching functions.
