Common faults in automotive turbochargers include: 1. Foreign object entry into the turbocharger: This may be caused by poor sealing of the intake pipe, allowing unfiltered air to enter the compressor impeller directly, failure to replace the air filter as required, or foreign objects entering the turbocharger intake pipe during maintenance. 2. Radial damage to the turbine by foreign objects: Damage to components within the diesel engine cylinder, foreign objects entering the exhaust manifold during maintenance, ultimately leading to rotor seizure or shaft breakage. 3. Contaminated turbocharger lubricating oil: The engine uses an oil filter that does not meet specifications, or inferior filter elements are used. During operation, the filter element may be punctured or the engine's main oil passage filter may become clogged, and the lubricating oil is not replaced as required. 4. Insufficient or aged turbocharger lubricating oil: Failure to replace the lubricating oil as required, or the use of inferior lubricating oil.

Can electronic eyes detect fake license plates?

Electronic eyes can accurately capture the information on the annual inspection sticker, allowing them to accurately determine whether a license plate is fake. Electronic Eyes: Electronic eyes utilize various technologies such as vehicle detection, photoelectric imaging, automatic control, network communication, and computers to monitor traffic violations like running red lights, driving in the wrong direction, speeding, crossing lines, and illegal parking around the clock. They capture images and information of traffic violations for subsequent processing. Fake License Plates: Fake license plates are made to mimic the model and color of a genuine vehicle, with the same license plate number applied to a vehicle of the same model and color. This is done to allow the vehicle to operate normally without detection.

Can modified bumpers and grilles pass the annual inspection?

Whether modified bumpers and grilles can pass the annual inspection depends on compliance with relevant laws and regulations. Modified grilles: Whether a car with a modified grille can pass the annual inspection depends on whether the grille manufacturer has filed for approval and whether the vehicle matches the photo on the registration certificate. Without approval from the traffic management department, modifying the grille is illegal, making it impossible to obtain a license plate or pass the annual inspection. Modified bumpers: Before modifying front or rear bumpers, approval must be obtained from the vehicle management office. Only modifications with proper documentation after approval can pass the annual inspection. Unauthorized modifications without approval will fail the inspection, and the original configuration must be restored to pass.

Is It Safe to Store Beer in the Trunk in Hot Weather?

Storing beer in the trunk in hot weather is not safe. Beer may explode: Storing beer in the trunk in hot weather may cause it to explode. This is because a large amount of gas is injected into the beer during production. If the road is bumpy while driving, the combination of high temperatures and vigorous shaking can cause the carbon dioxide inside the beer to continuously release, increasing the pressure inside the bottle. When the pressure reaches a certain level, the beer bottle may rupture and explode. Beer exposed to sunlight in the car: The ideal storage conditions for beer are between 5°C and 25°C, away from light. Beer exposed to sunlight in the car will have its flavor balance disrupted, resulting in a poor taste. Additionally, the bitterness from hops and tannins will oxidize, the beer's color may turn red, and cloudiness may occur prematurely, indicating that the beer itself has deteriorated.
