You can still drive when the tire pressure warning light is on. If the tire pressure light comes on while driving, stay calm and avoid panic. Immediately reduce your speed, avoid sharp steering and sudden braking, and check the tires as soon as possible. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure readings for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotational speed between tires, the system monitors tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): TPMS combines the advantages of both systems mentioned above. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and addresses the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.

Where to Check China VI Emission Standard?

Check the vehicle's factory certificate or vehicle conformity certificate. Symbol markings: The symbols for China 1 to China 6 standards are I, II, III, IV, V, and VI respectively. China first introduced the China 1 emission standard on July 1, 2000. As it was based on European emission standards and aligned with international norms, Roman numerals were adopted for the China 1 to China 6 markings. New emission standards have been introduced every few years since then. China VI standard: The "China VI standard" is divided into two phases: "China VI a" and "China VI b", with nationwide implementation planned for July 1, 2020 and July 1, 2023 respectively. However, the China VI standard is extremely stringent, far exceeding Europe's Euro 6 and America's Tier 3 standards, making it one of the strictest emission standards globally. The implementation period for China VI standards will also be longer.

How Many Digits Does an Engine Number Have?

The common engine number generally consists of 7-8 digits. The sequence and content of the engine number may vary depending on the manufacturer. It usually includes the engine model, production date, and a randomly assigned serial number when the engine comes off the production line. Some may also include a location code. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to represent information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power, among others. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer, model, and production number of the engine. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of a Vehicle Engine Number: Front Section: Includes the product series code, generation symbol, and regional or corporate code, which are selected by the manufacturer as needed, subject to approval and filing by the industry standardization authority. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Rear Section: Comprises symbols for structural features and intended use. Tail Section: Distinguishing symbol. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer may choose an appropriate symbol to indicate this, with the rear and tail sections potentially separated by a hyphen (-).

How Often Should Brake Pads and Brake Discs Be Replaced?

Disc brake pads generally need to be replaced after the vehicle has traveled 60,000 to 80,000 kilometers. The lifespan of brake discs is typically over 3 years or 100,000 kilometers. Four warning signs before brake failure: 1. Abnormal noises when braking: If a sharp and harsh metal friction sound is heard when applying the brakes while driving, there are two possible scenarios: it may be due to the brake pads wearing thin, causing the wear limit indicator to come into contact with the brake disc, indicating that the brake pads have reached their limit and need immediate replacement. Alternatively, the noise could be caused by foreign objects in the brake pads or rust on the brake discs. In most cases, pressing the brakes a few more times may alleviate the noise, but if it persists, a visit to the repair shop is necessary. 2. Soft brakes: If the brakes feel soft, the issue might lie in the brake lines or the brake master cylinder. First, press the brake pedal to check for any brake fluid leaks. If no external leaks are found, inspect the wheel cylinders or the master cylinder for faults. If the pedal height slightly increases and feels spongy after several presses, it indicates air has entered the brake lines. 3. Hard brakes: If the brake pedal is difficult to press, the problem could be with the brake booster pump or a damaged one-way valve in the vacuum reservoir. Regardless of the cause, if the brake pedal feels unusually high and stiff or lacks free travel, it is crucial to visit a repair station immediately. 4. Brake pull: Brake pull occurs when the vehicle veers to one side during braking, causing the steering wheel to noticeably pull in one direction. This is usually caused by uneven wear on the brake pads or issues with the brake calipers, resulting in uneven braking force on either side. Therefore, immediate inspection at a repair shop is required if this occurs.

Is the window tint provided by 4S stores for new cars applied to the entire vehicle or just the windows?

4S stores generally provide window film. Here is an introduction to vehicle window tinting: Introduction to car window tinting: Car window tinting involves applying a thin film to the front and rear windshields, side windows, and sunroof of a vehicle. This film is also known as solar film or heat-insulating film. Functions of car window tinting: Its main functions are to block ultraviolet rays, reduce heat, prevent serious consequences from glass shattering in special situations, and reduce glare. Additionally, the one-way transparency feature of solar film helps protect personal privacy. Thickness of heat-insulating film: The thickness of car heat-insulating film is typically around 1.5 mil. 'Mil' is an imperial unit, where 1 mil equals one-thousandth of an inch, or 0.0254 mm.

How to Solve the Problem of Always Smelling Exhaust Fumes in the Cabin?

Bamboo charcoal bags have strong odor adsorption capabilities, making this method very effective in eliminating odors inside the car, with long-lasting effects. Bamboo charcoal bags can selectively adsorb various substances in the air to achieve disinfection and deodorization. Additionally, bamboo charcoal bags are inexpensive and easy to purchase, making them an excellent choice for odor removal. It is recommended to choose bamboo charcoal. More detailed information is as follows: 1. Fruits like pomelos and lemons also have excellent odor-removing effects. The efficacy of pomelos is similar to that of bamboo charcoal bags, with the ability to adsorb odors, while lemons are effective due to their strong and long-lasting fresh scent. Natural ventilation methods, such as opening windows for cross-ventilation while driving and keeping windows open as much as possible when parked, can accelerate gas dissipation. After buying a new car, try to avoid adding interior decorations. If decorations are necessary, choose high-quality products. Also, avoid exposing the new car to direct sunlight, as heating can make odors harder to remove and harmful to health. The most important thing is to thoroughly inspect the car before purchase, eliminating potential odors during the selection process. 2. Additionally, odors inside the car may be caused by a dirty cabin air filter. A dirty cabin air filter can lead to unpleasant smells. It is recommended to replace the cabin air filter and perform a cleaning of the air conditioning ducts, which can effectively remove odors and maintain clean ducts.

What is the Principle of the Engine Valve Train?

The principle of the engine valve train is to open and close the intake and exhaust valves of each cylinder in a timely manner according to the working cycle and ignition sequence requirements of the engine, allowing fresh air to be drawn into the cylinder and exhaust gases to be expelled after combustion. Below is a detailed explanation: 1. When the working cycle of the cylinder requires the valves to open for gas exchange, the crankshaft drives the camshaft to rotate through the transmission mechanism. The raised part of the cam on the camshaft pushes the rocker arm to swing via the tappet, push rod, and adjusting screw. The other end of the rocker arm then pushes the valve downward, further compressing the spring. Once the peak of the cam's raised part passes the tappet, the thrust on the tappet gradually decreases. The valve's opening gradually reduces under the tension of the spring until it finally closes. 2. The valve train often uses overhead valves and is categorized into underhead, mid-head, and overhead types based on the camshaft's position. The valve train consists of two main parts: the valve drive group and the valve group. The valve drive group includes the crankshaft timing gear, camshaft timing gear, camshaft, tappet, push rod, rocker arm, valve clearance adjusting screw, lock nut, and rocker arm shaft. The valve group includes the valve, valve guide, valve spring, valve spring seat, valve oil seal, and valve seat. 3. When the maximum raised part of the cam contacts the tappet, the valve reaches its maximum opening. Subsequently, the raised surface of the cam in contact with the tappet gradually decreases, and the valve begins to close under the action of the valve spring, reversely pushing the rocker arm and other transmission components, causing the tappet to move downward to maintain contact with the cam. When the raised part of the cam leaves the tappet, the valve fully closes.
