Do small cars still need to display the compulsory insurance sticker?

With the introduction of electronic insurance policies, it is no longer necessary to display the compulsory traffic insurance sticker. Below is relevant information about compulsory traffic insurance: Description: Compulsory traffic insurance is a mandatory national insurance, and vehicles can only be driven on the road after purchasing it. Compulsory traffic insurance compensates for the losses of the victim party, but the compensation amount is limited, and it does not cover the losses of the vehicle owner who purchased the insurance. Given the frequent occurrence of traffic accidents nowadays, even minor collisions or rear-end accidents require supplementary commercial auto insurance. Important Notes: Compulsory traffic insurance and third-party liability insurance must be purchased, but do not overlook vehicle damage insurance, especially for new drivers who are not yet skilled. Vehicle damage insurance ensures that your own vehicle can receive adequate compensation in the event of an accident.

Why does the car air conditioner have no airflow in gears 1-3 but works in gear 4?

123 gears not blowing air while only gear 4 works is due to the blower speed control resistor. Below are relevant details about the car blower resistor: Introduction: The blower resistor is an important control component. By controlling the car blower resistor, the operating state of the car blower can be regulated, thereby achieving certain control effects and ensuring proper operation. Function: The car blower plays a crucial role in the vehicle. It serves as the heart of the car's air conditioning system, enabling normal functioning of the AC system. The car blower resistor is a key component of the blower. During blower operation, it is essential to monitor the blower regularly, paying attention to factors such as current, oil temperature, oil pressure, intake vacuum, sound, blower temperature, and vibration. Timely records should be maintained, and if any abnormalities are detected, the cause should be identified and addressed promptly, with reports made to the production department. Emergency shutdown measures may be taken if necessary.

Why does the car have high RPM but can't increase speed?

The reason for high engine RPM but inability to increase speed may be due to burnt clutch plates; here are additional details: Other possible reasons: Insufficient clamping torque of the friction plate clutch; transmission oil not changed for too long or damage to hydraulic mechanisms in the transmission; slipping of internal friction plates in the transmission; failure in the engine's electronic control system. About car RPM: Car RPM refers to the rotational speed of the car engine. The tachometer is located on the instrument panel, symmetrically placed with the speedometer. Functions of car RPM: To promptly reflect the engine's operating condition; to help drivers better coordinate transmission gear positions and throttle position; to maintain the car in optimal working condition; to reduce consumption and prolong engine lifespan.

Vehicle Inspection or Insurance Renewal First?

Vehicle annual inspection must be conducted within the validity period of compulsory traffic insurance, so the compulsory traffic insurance must be purchased and become effective before the vehicle can be inspected. Here is relevant information: 1. Best time: Vehicles can apply for inspection within 3 months before the annual inspection date. It is best to do it two months or more than one month in advance, rather than waiting until there are only a few days left before the inspection expires. In addition, before the 10th of each month, the workload of inspection stations is relatively low, which is a good opportunity to avoid queues. The number of vehicles starts to increase in the middle of the month, and the end of the month is the peak period. 2. Required documents for vehicle annual inspection (individual): Original driving license, copy of compulsory traffic insurance, copy of ID card, and the vehicle. Renew the insurance first and then inspect the vehicle. Because during the annual inspection, it is necessary to check whether the vehicle has lapsed in insurance. If the vehicle is in a state of insurance lapse, it cannot pass the annual inspection normally. Here is relevant information about vehicle annual inspection: 1. Inspection time: The owner of the vehicle can apply for the inspection compliance mark to the vehicle management office at the place of registration within three months before the expiration of the vehicle inspection validity period (vehicles after September 2012 are inspected every 6 years). The inspection time is within three months before the annual registration date of the driving license. 2. Documents: Before the annual inspection, check the validity date of the compulsory traffic insurance that includes the vehicle and vessel tax. If it has expired or will expire within three months after the inspection date, it is recommended to renew it in advance. The ID card of the owner or the agent; the vehicle driving license.

How many kilometers should a car's piston rings be replaced?

It is best to replace them every 500-1000 kilometers. Below is relevant information about piston rings: Definition: A piston ring (Piston-Ring) is a metal ring fitted into the grooves of a piston. Piston rings are divided into two types: compression rings and oil rings. Compression rings are used to seal the combustible gas mixture in the combustion chamber, while oil rings are used to scrape off excess oil from the cylinder walls. Functions: Piston rings serve four main purposes: sealing, oil control (regulating oil), heat conduction (heat transfer), and guidance (support). Sealing: This refers to sealing the combustion gases, preventing them from leaking into the crankcase, minimizing gas leakage to improve thermal efficiency. Gas leakage not only reduces engine power but also degrades the oil, which is the primary task of the compression ring. Oil control (regulating oil): This involves scraping off excess oil from the cylinder walls while maintaining a thin oil film to ensure proper lubrication of the cylinder, piston, and rings. This is the main function of the oil ring.
