How to check the national emission standard of a vehicle on the Motor Vehicle Environmental Protection Website: Visit the Motor Vehicle Environmental Protection Website, enter the engine number and the name of the car manufacturer, and search. The result will show which national emission standard the vehicle meets. After the implementation of National VI, some regions or cities have already stopped issuing license plates for National IV vehicles. The requirements of National VI A standard are: 1. The carbon monoxide emissions per kilometer driven must not exceed 700 milligrams; 2. The non-methane hydrocarbon emissions per kilometer driven must not exceed 68 milligrams; 3. The nitrogen oxide emissions per kilometer driven must not exceed 60 milligrams; 4. The PM fine particulate matter emissions per kilometer driven must not exceed 4.5 milligrams.

What are the maintenance items needed for a car at 30,000 kilometers?

At 30,000 kilometers, the maintenance items required for a car include changing the engine oil, oil filter, air filter, and cabin air filter. Car maintenance, also known as vehicle servicing, refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. Car maintenance mainly involves the engine system, transmission system, air conditioning system, etc., aiming to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent faults, and extend the service life. Daily car maintenance, or routine maintenance, is the work carried out before driving, during driving, and after parking, performed by the driver. The main tasks include cleaning, replenishing, and safety inspections, which are regular and essential tasks to maintain the vehicle's normal working condition.

What is the function of an engine stabilizer bar?

The function of an engine stabilizer bar is to prevent body roll by generating anti-roll resistance when there is a difference in the horizontal height between the left and right wheels, thereby avoiding torsion of the bar itself. An engine is a machine that converts other forms of energy into mechanical energy, originating in the UK. It can refer to both the power generation device and the entire machine including the power unit. Types of engines include internal combustion engines (such as gasoline engines), external combustion engines (like Stirling engines and steam engines), and electric motors. An external combustion engine burns its fuel outside the engine itself and was invented by R. Stirling of Scotland, hence also known as the Stirling engine. Internal combustion engines come in a wide variety, with common examples being gasoline and diesel engines, which are typical internal combustion engines.

Should You Wash Your Car Before Applying Window Tint?

You should wash your car before applying window tint. If the car body is not clean, bumps will appear after the tint is applied, which not only affects the appearance of the car but also makes the raised areas prone to damage. Car window tinting involves applying a thin film to the front and rear windshields, side windows, and sunroof. This film is also known as solar film or heat insulation film. The primary functions of car window tinting are to block ultraviolet rays, reduce heat, prevent injuries caused by shattered glass, and reduce glare. Additionally, the one-way transparency feature of the solar film helps protect personal privacy. Furthermore, it can minimize damage to interior items and passengers caused by UV exposure, lower the interior temperature through physical reflection, and reduce the use of car air conditioning.

What is the appropriate length for car jumper cables?

Car jumper cables are generally suitable at a length of 3 meters. Cables that are too long will increase resistance and consume power, while cables that are too short are difficult to connect. When a car battery is low on power, it can affect the entire vehicle's power supply system, making it difficult to start the car. Use 16-gauge copper wires to interconnect the battery electrodes of both vehicles, then start the other car and let its engine idle. After that, attempt to start your own car. If the issue is a low battery, the car should start quickly. After starting, keep the engine running for 15 to 20 minutes to allow the alternator to recharge the battery. If the car battery is low on power, it should be promptly charged and reactivated using a battery charger. If the charger fails to charge the battery, a high-resistance repair device can be used to raise the voltage above 10V for recovery.

Why Can the Door Still Be Opened When It's Locked?
