What Causes the Engine Temperature to Rise During Normal Driving?

Normal driving with rising engine temperature can be caused by the following reasons: Low coolant level in the radiator. The engine relies on water cooling to lower its temperature. Although the coolant in the radiator depletes slowly, it still diminishes over time. Some car owners neglect to check the coolant level, leading to prolonged low levels and consequently high engine temperature. In such cases, the radiator needs to be refilled. Thermostat malfunction. Some drivers notice the engine temperature rising after just a few kilometers of driving, without any visible leaks in the hoses. This issue may stem from a thermostat that fails to open, preventing the car's cooling system from engaging in a full circulation cycle and causing high engine temperature. Replacing the thermostat is necessary here. Leaking hoses. If a leak is detected while driving, inspect whether the hoses are aged or cracked. This issue is relatively easier to identify, and the solution involves replacing the affected hoses at a repair shop. Poor radiator cooling. Some car owners use plain water as coolant. Prolonged use of water can lead to rust formation in the engine and radiator, impairing the radiator's cooling efficiency and resulting in high engine temperature. To resolve this, the rust must be removed first, followed by cleaning or replacing the radiator.

What Are the Hazards of Excessive Engine Oil?

The hazards of overfilling engine oil: It can cause the engine speed to rise very slowly during acceleration and may also damage the three-way catalytic converter. Below are some tips for adding engine oil: 1. When adding engine oil, it should be filled between the min and max marks on the dipstick. The oil level should not be below the min mark or above the max mark. If overfilled, some oil can be drained or extracted. 2. Engine oil is known as the lifeblood of the engine. It serves to lubricate, cool, clean, and seal within the engine. Without sufficient oil, the engine cannot operate properly. If the oil level is too low, some parts of the engine may not receive adequate lubrication, leading to increased wear. 3. 99% of engine wear occurs during cold starts. During a cold start, the oil has not yet reached the surfaces of the components that need lubrication, resulting in dry friction and the most severe engine wear. Once the engine starts, the oil pump begins normal operation, and the oil quickly reaches the surfaces of the components needing lubrication, forming a protective film, thereby reducing engine wear.

What are the consequences of not installing Chongqing electronic license plates?

Failure to install will result in fines. The electronic license plate is like a person's ID card, where each card has a globally unique, factory-set, unalterable ID number that is physically bound to the vehicle—one vehicle, one card. It cannot be removed or, if removed, will be destroyed, giving the electronic license plate tag unparalleled anti-counterfeiting performance. Expanded content: The functions of electronic license plates are as follows: 1. Vehicle registration management: Completes automatic electronic identification of vehicles. By comparing with backend database records, it verifies authenticity, checks inspection records (such as environmental monitoring, insurance purchases, etc.), and enables public security to query illegal vehicles. 2. Vehicle traffic management: Based on the data collection foundation of automatic electronic vehicle identification, it samples vehicle traffic data at major urban intersections through intelligent traffic management systems, enabling automatic classification, zoning, and time-based management of vehicles. This facilitates vehicle-to-vehicle and vehicle-to-road coordination, implements congestion zone charging, and uses economic leverage to reasonably organize and guide traffic, reducing vehicle flow in congested areas during peak hours. 3. Vehicle security management: By obtaining important information such as license plate numbers, plate colors, and vehicle types, it provides data support for combating theft and blacklisted motor vehicles, tracking down hit-and-run vehicles, and strengthening public security management. This helps prevent increasingly rampant criminal activities such as motor vehicle theft, robbery, fake plates, cloned plates, smuggling, and black market trading, while also providing strong evidence for handling various traffic accidents and incidents involving personal and property safety. 4. Road planning management: Through data analysis of vehicle categories (such as buses, trucks, cars, taxis, etc.) and traffic flow, it provides precise data on traffic volume, vehicle categories, peak periods, and peak values for road planning and design, enabling scientifically guided road planning.

What to Do When the Vehicle Braking System Shows Abnormalities?

It is recommended to promptly visit a 4S shop for inspection and repair if the braking system shows abnormalities. The operational state of a vehicle's braking system determines the safety of passengers inside the car. Only when it is in a healthy condition can it successfully decelerate or even stop the vehicle according to the driver's intention. Below are manifestations of braking system abnormalities: 1. There are many phenomena indicating a faulty braking system, specifically when the brake pedal does not rise upon pressing. The reason for this situation is the lack of brake fluid in the car. It is necessary to check for oil leaks at the brake calipers, pipelines, and joints, or to inspect whether the master cylinder or caliper components are damaged. 2. Sometimes, pressing the brake pedal all the way down results in poor braking performance. This is because there is air mixed in the braking system. If continuously pressing the brake pedal causes the pedal to return higher and the braking performance improves slightly, the fault may be due to excessive gap between the friction pads and the brake drum, requiring inspection and repair at a 4S shop. 3. If the brake pedal's position is very low, and when pressed, it does not rise, feeling extremely hard, this indicates a blockage in the brake master cylinder, which needs to be cleaned promptly.

Should the Volkswagen Bora use 92 or 95 gasoline?

According to the official car manual recommendation, the Volkswagen Bora should use 92 gasoline. In addition to checking the suitable gasoline grade in the car manual, you can also check the fuel tank cap, which will also indicate the recommended gasoline grade. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should choose 92 gasoline, while those with a compression ratio between 10.0-11.5 should choose 95 gasoline. However, with the use of some new technologies, the gasoline grade cannot be determined solely by the compression ratio. A high compression ratio can also be adjusted to use low-grade gasoline 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 gasoline contains 92% isooctane and 8% n-heptane, while 95 gasoline contains 95% isooctane and 5% n-heptane. If the Volkswagen Bora occasionally uses the wrong gasoline grade, simply switch back to the correct grade after using it up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use low-grade gasoline, using high-grade gasoline by mistake will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use high-grade gasoline, using low-grade gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If it is mild knocking, it will only increase noise and cause minimal damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on the pistons and cylinders, and in severe cases, cylinder scoring.
