What Causes the Wuling Zhiguang's Radiator to Frequently Boil Over?

The frequent boiling over of the Wuling Zhiguang's radiator may be caused by several factors, including a faulty engine thermostat that fails to open, insufficient coolant, a malfunctioning engine water pump, a clogged radiator, or a non-functioning cooling fan. It is recommended to visit a 4S shop or an auto repair shop to diagnose the specific issue. The detailed reasons are as follows: Reduced Heat Exchange Efficiency: Issues such as a damaged thermostat, a faulty electric fan, or low coolant levels in the cooling system can prevent the coolant in the radiator from cooling down, leading to a rise in water temperature. When the boiling point of water is reached, a large number of bubbles form, occupying part of the radiator's surface area. This results in severe coolant depletion around the cylinder walls, even if there is still coolant in the radiator. Without sufficient coolant around the cylinder walls to dissipate heat, heat exchange efficiency is significantly reduced, making it impossible to transfer heat from the cylinders to the radiator. High-Load Driving: When the temperature inside the cylinders rises rapidly, continued high-load driving without timely heat dissipation can weaken components such as pistons, piston rings, and connecting rods, potentially causing deformation. These parts may then fail to withstand normal loads, and the normal gaps between components can be disrupted, preventing the formation of proper oil films. In mild cases, this can lead to engine cylinder or bearing damage; in severe cases, the entire engine may be damaged or even rendered unusable.

Can someone else take the penalty points for a DiDi operating vehicle's traffic violation?

No, having someone else take the penalty points is illegal. When capturing traffic violations, not only the vehicle but also the driver is photographed. When handling the violation, the driver must present their own driver's license. The staff will strictly check whether the person clearing the points is the one who committed the violation at the time. Only after confirming that the person is the violator and that there are no issues with the driver's license and vehicle registration will the penalty points be processed. Additional information: 1. If the penalty points do not reach 12 in a scoring cycle: If the driver's penalty points in a scoring cycle do not reach 12 and the fines have been paid, the points will be cleared. If the points do not reach 12 but there are unpaid fines, the points will carry over to the next cycle. 2. If the accumulated points reach 12 in a scoring cycle: If a driver's accumulated points reach 12 in a scoring cycle, the public security traffic management department will confiscate their driver's license. The driver must report to the traffic management department of the public security authority where the driver's license was issued or where the violation occurred within 15 days to receive seven days of education on road traffic safety laws, regulations, and related knowledge, and must also take the subject one exam. 3. If the points reach 12 and the driver refuses to participate in the education: If a driver's points reach 12 and they refuse to participate in the education or take the exam as notified by the traffic management department of the public security authority, their driver's license will be suspended by the traffic management department of the public security authority.

Changan Oushang X5: Should You Use 92 or 95 Octane Gasoline?

According to the official vehicle manual recommendation, the Changan Oushang X5 should use 92 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap of the Changan Oushang X5. Typically, the appropriate gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should opt for 95 octane gasoline. However, with the application of some new technologies, the compression ratio alone cannot determine the gasoline grade, as engines with high compression ratios can also be tuned to use lower-grade gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in the Changan Oushang X5, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-grade gasoline, using higher-grade gasoline will not cause damage, but the increase in octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the actual feedback being poorer performance. For vehicles recommended to use higher-grade gasoline, using lower-grade gasoline can cause engine knocking. Due to the significantly lower octane number, the fuel's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise without obvious damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

How to Set Up a Reversing Camera Black Screen?

The methods to set up a reversing camera black screen are: 1. Turn off the engine, remove the navigation card, reinsert it, and restart; 2. Check the wiring and the connection points of the vehicle installation; 3. Replace the power cable with a new one. The reasons for a reversing camera black screen are: 1. Poor wiring contact; 2. Aging of the video power cable; 3. The reversing camera has been used for too long; 4. Defects in the vehicle circuit design. The reversing camera captures real-time images of the area behind the vehicle through a rear-mounted camera and displays them on the central control screen. The driver can observe the situation behind the vehicle based on the screen, enhancing parking safety.
