The brake vacuum pump may be leaking air. You need to check whether it's the pipeline or the brake drum specifically. Symptoms of damage: The symptoms of a faulty brake vacuum pump include poor braking performance or no braking effect. Operating principle: During the braking process, the vacuum entering the booster pump is controlled to move the diaphragm. Through a linkage device, the push rod on the diaphragm assists the driver in stepping on and pushing the brake pedal, thereby amplifying the force applied by the driver. Specific function: The vacuum booster pump uses the vacuum generated by the engine during operation to provide some assistance to the driver when stepping on the brake, making braking feel lighter. If the vacuum booster pump is damaged, there will be no assistance, making the brake pedal feel heavier. The vacuum pump cannot be repaired and must be replaced.

Ultrasonic waves are mechanical waves with vibration frequencies higher than 20kHz: Ultrasonic sensors can detect transparent or colored objects, metallic or non-metallic materials, as well as solids, liquids, and powdered substances. Their detection performance is nearly unaffected by any environmental conditions, including smoky or rainy environments.

Is it necessary to pay the vehicle and vessel tax when purchasing compulsory traffic insurance?

Yes, it is required. The vehicle and vessel tax is included in the compulsory traffic insurance fee, which is mandatory by the state. Without purchasing it, you cannot drive on the road. Otherwise, according to the "Road Traffic Safety Law," you may face a warning or a fine ranging from 20 to 200 yuan. Article 95 stipulates: If a motor vehicle driven on the road does not display an inspection qualification mark or insurance mark, or the driver does not carry the vehicle license or driving license, the traffic management department of the public security organ shall detain the motor vehicle and notify the party to provide the corresponding license, mark, or complete the necessary procedures. Compulsory Traffic Insurance for Vehicles: The full name of compulsory traffic insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates for personal injury, death, and property losses of victims (excluding vehicle occupants and the insured) caused by road traffic accidents within the liability limits. The premium is based on the nationally unified standard rates. However, the price of compulsory traffic insurance varies for different vehicle types, mainly influenced by the number of seats. Compared to the more than 20 exemption clauses in commercial third-party insurance, compulsory traffic insurance covers a much broader range, including losses caused by intentional acts of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses caused by accidents. Moreover, regardless of whether the insured vehicle is at fault in an accident, compulsory traffic insurance will compensate within the liability limits, with no deductible or exemption. Vehicle and Vessel Tax: Vehicle and vessel tax refers to a tax payable by owners or managers of vehicles and vessels within the territory of the People's Republic of China according to the Vehicle and Vessel Tax Law of the People's Republic of China. Since July 1, 2007, drivers must pay the vehicle and vessel tax when purchasing compulsory traffic insurance. Introduction to Electronic Insurance Policies An electronic insurance policy refers to a digital policy issued by an insurance company with an electronic signature, using digital signature software and enterprise digital certificates that comply with the PKI system. An insurance policy, abbreviated as a policy, is the official written proof of an insurance contract between the insurer and the insured. The policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the policy serves as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks; Time-saving and convenient, not restricted by time or location, with information accessible online anytime, quickly and easily; Can apply for reissuance or resending, eliminating worries about losing it. If a paper version is needed offline, it can also be printed or mailed; Easy management, as electronic unification makes it easier for insurance companies and traffic police departments to manage the insurance information of each vehicle.

Is driving at 120 km/h considered speeding on a highway with a 100 km/h speed limit?

On a highway with a speed limit of 100 kilometers per hour, if a motor vehicle reaches 120 kilometers per hour, it is considered speeding. Highways also have speed measurement sections, and speeding violations will be penalized. On highways, the maximum speed for small passenger vehicles cannot exceed 120 kilometers per hour, while other motor vehicles cannot exceed 100 kilometers per hour, and motorcycles cannot exceed 80 kilometers per hour. On highways: some sections have a maximum speed limit of 100 kilometers per hour, while others have a limit of 120 kilometers per hour. If you are driving in a section with a maximum speed limit of 100 kilometers per hour, any speed exceeding 100 kilometers per hour is considered speeding. If the speeding is within 10%: there will be no penalty points or fines, only a warning will be issued. However, if the speeding exceeds 10%, penalty points and fines will be imposed. Therefore, if the speed limit is 100, as long as you do not exceed 110, there will be no penalty points or fines. Exceeding 110 will result in fines and penalty points.

How Often Should Spark Plugs Be Replaced in a Sedan?

Under normal maintenance conditions, spark plugs in a sedan should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the vehicle's manual. Below are some general guidelines for spark plug replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs between 60,000 to 80,000 kilometers. Methods to determine if a spark plug is damaged: Remove the spark plug and inspect its appearance to assess its condition. A normal spark plug will have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is covered in oil or deposits but is otherwise undamaged, it can be cleaned and reused. If the spark plug is severely damaged, showing signs such as blistering at the tip, black streaks, cracks, or melted electrodes, the cause of the damage should be identified and resolved before replacing the spark plug. Additionally, if the spark plug appears blackened as if smoked, it may indicate the wrong heat range was selected or that the air-fuel mixture is too rich, or that oil is leaking into the combustion chamber.
