The Difference Between Tire Pressure Warning and Tire Pressure Monitoring?

2 Answers

Tire pressure display belongs to active tire pressure monitoring, while tire pressure warning belongs to passive tire pressure monitoring. The following is an introduction to the differences between the two: 1. Different functions: The tire pressure display can directly show the current tire pressure, while the tire pressure warning calculates the deviation of tire pressure between the two sides exceeding the limit by comparing data such as the rotational speed and torque of the tires on both sides, and then issues a warning. 2. Different types: Tire pressure monitoring is mainly divided into two types, one is indirect tire pressure monitoring (Wheel-Speed-Based-TPMS, referred to as WSB), and the other is direct tire pressure monitoring (Pressure-Sensor-Based TPMS, referred to as PSB).

Tire pressure warning and tire pressure monitoring sound similar, but their core difference lies in functionality. I gradually understood this as a novice driver: a tire pressure warning is just an alert system. When the car's sensors detect abnormal tire pressure, a light on the dashboard turns on or it beeps to notify you of an issue, but it won't specify which tire or the exact pressure value. It's like receiving an urgent text message—you have to figure out the problem yourself. Tire pressure monitoring, on the other hand, is much more advanced. It displays real-time pressure readings for each tire on the screen, allowing you to check anytime, almost like having a surveillance camera with all the data under control. The warning focuses on timely alerts to prevent worsening conditions, such as dangerously low pressure that could lead to a blowout. Monitoring, however, helps prevent issues by allowing you to adjust tire pressure in advance, saving money and fuel. I think the warning is basic, while monitoring is more practical. Many cars only have the warning function, which is an indirect system, whereas monitoring requires a sensor on each wheel. It's important to develop a habit of regularly checking tire pressure and to stop immediately to measure pressure or visit a repair shop if the warning light comes on.

What are the differences between Volvo T3, T4, and T5?

T3 is a 1.5T three-cylinder engine, while T4 and T5 are both 2.0T inline 4-cylinder engines. The T3 1.5T three-cylinder engine has a maximum power output of 120KW and a maximum torque of 265N·m. The T4 2.0T inline 4-cylinder engine delivers a maximum power of 140KW and a maximum torque of 300N·m. The T5, also a 2.0T inline 4-cylinder engine, boasts a maximum power of 185KW and a maximum torque of 350N·m. Below are the relevant details about these three engines: 1. Different engines: The distinction between these engine types lies in their power output. The T3 is a 1.5T three-cylinder engine, whereas the T4 and T5 are both 2.0T inline 4-cylinder engines. 2. Different power outputs: The T3 has a maximum power of 120KW and a maximum torque of 265N·m. The T4 offers a maximum power of 140KW and a maximum torque of 300N·m. The T5 provides a maximum power of 185KW and a maximum torque of 350N·m.

How Long Does Painting Take?

The time required for car painting is primarily determined by the scope of the painting. Generally, at a 4S shop, the fastest turnaround is 2-3 days. Below are the precautions for painting and methods for car paint maintenance: Precautions for Painting: After painting, check if the painted surface matches the original car paint color perfectly. Inspect the smoothness of the painted surface for any bubbles, pits, or impurities. Examine the uniformity of metallic paint particles, observing their size, color, and arrangement to ensure consistency and harmony with the original car paint. Methods for Car Paint Maintenance: To enhance the lifespan and appearance of the car paint, wash the car regularly to remove stains and dust. Avoid strong impacts, bumps, or scratches to the car's paint film. If any scratches, dents, or peeling are found on the painted surface, repair them promptly.

What Causes No Response When Pressing the Accelerator?

The reasons for no response when pressing the accelerator include ignition system failure, fuel injection system failure, and throttle pedal sensor failure. Below are detailed explanations: Ignition System Failure: Failure of the ignition coil and spark plugs in the ignition system leads to poor ignition performance, making it difficult to achieve noticeable power improvement even when pressing the accelerator. Fuel Injection System Failure: Failure of the high-pressure fuel pump or excessive carbon buildup in the fuel injectors results in poor fuel injection performance, causing no response when pressing the accelerator. Throttle Pedal Sensor Failure: Throttle pedal sensor failure is the most direct cause and requires replacement of a new sensor.

What is the service life of commercial vehicles?

Commercial vehicles have different service life periods depending on the vehicle type. Please see the detailed explanations below: 1. Non-commercial passenger vehicles with 9 seats or less (including sedans and SUVs) have a service life of 15 years: If continued use is required after reaching the scrapping standard, no approval is needed. The service life can be extended after passing inspections, with 2 annual inspections required. After 20 years, 4 annual inspections are required starting from the 21st year. 2. Tourist passenger vehicles and non-commercial passenger vehicles with more than 9 seats have a service life of 10 years: If continued use is required after reaching the scrapping standard, the current procedures must be followed, but the extension cannot exceed 10 years. Tourist passenger vehicles with extended service life require 4 annual inspections, while non-commercial passenger vehicles with more than 9 seats require 2 annual inspections, increasing to 4 annual inspections starting from the 16th year after exceeding 15 years. 3. The service life of commercial buses is adjusted to 10 years: If continued use is required after reaching the scrapping standard, the current procedures must be followed. The extension cannot exceed 4 years, with 4 annual inspections required during the extended period. 4. For the above vehicles during regular inspections: If they fail to meet the national standard "Safety Specifications for Power-driven Vehicles Operating on Roads (GB7258-2004)" in 3 consecutive inspections within one inspection cycle, the license plate and vehicle registration certificate will be revoked, and the vehicle owner will be notified to complete the deregistration process. After reaching the scrapping standard, registration and transfer registration are not allowed. 5. Important note: Commercial vehicles converted to non-commercial use and non-commercial vehicles converted to commercial use will be scrapped according to the commercial vehicle standard (8 years).

What Causes Water to Drip from the Car Chassis?

The reasons for water dripping from the car chassis are drainage from the air conditioning system and water dripping from the muffler and exhaust pipe at the rear of the car. Here are the detailed explanations: Air Conditioning System Drainage: Air conditioning system drainage occurs because the outside temperature is high in summer while the interior of the car with the air conditioning on is cold, creating a temperature difference that causes water to drip from the chassis. The low-pressure pipes of the car's air conditioning system are not wrapped with thermal insulation foam, making the pipe surfaces prone to condensing moisture from the air. Water droplets also condense and collect at the lowest point of the pipes, dripping down. Muffler and Exhaust Pipe Dripping: Water dripping from the muffler and exhaust pipe at the rear of the car is also a normal phenomenon, commonly seen in winter. This phenomenon indicates that the engine is in good working condition, with the air-fuel mixture burning completely and efficiently.

Can a Car Battery with Broken Cells Still Be Used?

After a battery has broken cells, it cannot be used and should be repaired immediately. The causes and repair methods for broken battery cells are as follows: Causes of Broken Battery Cells: The reasons for broken battery cells include poor battery quality; incorrect usage leading to internal short circuits; frequent battery use; or severe impacts or drops. Repair Methods for Broken Battery Cells: For a battery with broken cells, the problematic single cell can be extracted and replaced. After replacement, seal it with sealing glue, weld the terminals, add electrolyte, and finally charge the battery. Those with the necessary skills can attempt to repair it themselves, but it is best to seek professional help at a repair shop.
