As a crucial component for safe driving, brakes should be given special attention by every driver. Before each drive, it's advisable to test the working condition of the brake pedal. When the engine is not started, the brake pedal will feel very firm; after normal engine startup, the brake pedal will slightly sink. The reasons for soft brakes include the following: 1. Mixed brake fluid: Using different brands of brake fluid together can reduce braking performance. 2. Air in the brake fluid: The presence of unexpelled air in the brake fluid. 3. Oil leakage or poor sealing: Oil leakage in the master cylinder or wheel cylinders, or poor sealing. 4. Damaged outer packaging: Damage to the external casing of the brake lines.

What does the B2 inspection validity period mean?

The B2 inspection validity period refers to the deadline for the annual inspection of a B2 driver's license. If the date recorded on the license is May 1, 2022, the vehicle owner must complete the inspection process at the vehicle management office before May 1, 2022. If there are no traffic violation points recorded during the current cycle, the owner can be exempted from this inspection. However, if there are violation points, the owner must complete the relevant procedures. For Class C motor vehicle driver's licenses, the inspection period has been abolished, and only renewal is required upon expiration. Driving with an uninspected license, if discovered by traffic police, will result in penalties. Even if the owner is unaware of the inspection requirement, they cannot be exempted. Therefore, it is crucial for vehicle owners to remember the validity period of their license and complete the inspection process in a timely manner. The inspection for a B2 motor vehicle driver's license can be conducted at the vehicle management office or the traffic management department of the public security authority. Alternatively, it can be completed via the "Traffic Management 12123" app (V2.8.1B274) on Android 12 or higher. After the inspection, the driver's license will be restored to 12 points and can be used without issue. For the first renewal of the license, if no scoring cycle within the 6-year validity period has accumulated 12 or more points, the license will be renewed with a 10-year validity period. If any scoring cycle within the 6-year period accumulates 12 or more points, the license will still be renewed with a 6-year validity period. Similarly, after obtaining a 10-year license, if no scoring cycle within the 10-year period accumulates 12 or more points, the next renewal will issue a long-term valid license. A B2 driver's license is valid until the holder reaches 60 years of age. Drivers holding B2, B1, A2, A1, or A3 licenses will no longer be permitted to drive large or medium-sized passenger or cargo vehicles, tow trucks, or city buses after turning 60. They must visit the issuing vehicle management office to complete the downgrade and renewal procedures, typically switching to a small passenger vehicle or small automatic transmission vehicle license. A B2 driver's license allows the holder to operate manual or automatic transmission passenger vehicles with 9 or fewer seats, as well as heavy, medium, or large cargo vehicles or specialized operation vehicles. Other permitted vehicle types include C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed cargo vehicles), C4 (three-wheeled cars), and M (wheeled self-propelled machinery). Medium and heavy cargo vehicles are primarily trucks, such as those commonly seen transporting construction debris. Medium, large, and heavy specialized operation vehicles refer to vehicles equipped with specialized devices or tools, such as fire trucks or water sprinklers. To apply for a B2 driver's license, the following requirements must be met: Possession of a C1 driver's license for at least 3 years. Age between 22 and 50 years old. Unaided or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart for both eyes. No more than 12 penalty points accumulated in the most recent scoring cycle. No record of serious traffic accidents or drunk driving. The following conditions disqualify an applicant from obtaining a B2 license: Being responsible for a fatal traffic accident with equal or greater liability. Driving under the influence of alcohol. Having a driver's license revoked or rescinded within the past 10 years.

What is an Intake Manifold Absolute Pressure Sensor?

An intake manifold absolute pressure sensor is a device that detects the absolute pressure in the intake manifold behind the throttle. It connects to the intake manifold via a vacuum tube and senses the vacuum changes inside the intake manifold as the engine operates under different speeds and loads. The sensor then converts the changes in internal resistance into a voltage signal, which the ECU uses to adjust fuel injection volume and ignition timing. The intake manifold absolute pressure sensor detects variations in absolute pressure within the manifold based on engine speed and load, converts this into a signal voltage, and sends it to the engine control unit (ECU). The ECU then uses this signal voltage to determine the basic fuel injection volume.
