What does it mean when a heavy truck's Beidou system goes offline?

When a heavy truck's Beidou system goes offline, it means the driving recorder is in an offline state. The following are the reasons that may cause the device to go offline: 1. Unable to receive signals: Under normal circumstances, the onboard terminal achieves positioning by receiving satellite signals, then transmits the processed data to various provincial monitoring platforms via the telecom operator's network, and the provincial platforms upload the data to the national freight big data platform. The signal status is displayed on the device's screen. If the device malfunctions, or the vehicle is in a location with poor signal such as a basement or tunnel, the driving recorder may fail to receive satellite signals or transmit its own data, in which case the device will show as offline. 2. SIM card out of service due to unpaid fees: Another situation is when the SIM card inside the device is out of service due to unpaid fees, which can also cause the device to go offline. 3. Intentional damage: It is also possible that the driver intentionally damages or modifies the device to evade monitoring.

Why is there a gasoline smell during cold engine start?

Reasons for gasoline smell during cold engine start: 1. Under very low external temperatures, when the water temperature and exhaust pipe temperature are low, combined with the extremely cold external conditions during winter driving, the air-fuel mixture becomes too rich. As a result, some unburned mixture is directly discharged through the exhaust pipe, leading to a noticeable gasoline smell; 2. A malfunction in the carbon canister or its solenoid valve causes an overly rich mixture during startup; 3. Fuel injector leakage leads to an excessively rich mixture, and the unburned mixture is expelled through the exhaust pipe, resulting in a strong gasoline odor. Cold start refers to starting the engine when the coolant temperature is low, typically after the vehicle has been inactive for an extended period.

What is the operation process for replacing brake fluid?

The operation process for replacing brake fluid is: 1. Use a machine to suck out the brake fluid from the drain nut, then continuously add new brake fluid to the reservoir and repeat the operation; 2. Continue until the discharged brake fluid is clear and free of air, then use the same method to replace the brake fluid for the remaining three wheels. Brake fluid, also known as hydraulic fluid, should be purchased from reliable manufacturers, and the higher the grade, the better. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when the liquid is under pressure, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking works based on this principle.
