Electric vehicle shock absorber oil leakage does not affect safety in the short term. Here is some related information about shock absorbers: 1. Introduction: The shock absorber (Absorber) is used to suppress the oscillation after the spring absorbs vibration and rebounds, as well as the impact from the road. It is widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the driving smoothness of the vehicle. When passing over uneven road surfaces, although the shock-absorbing spring can filter out road vibrations, the spring itself still undergoes reciprocating motion, and the shock absorber is used to suppress this spring bounce. 2. Working Principle: Most shock absorbers used in automotive suspension systems are hydraulic shock absorbers. Their working principle is that when relative motion occurs between the frame (or body) and the axle due to vibration, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different orifices.

As a long-time electric vehicle owner, I've experienced shock absorber oil leakage, which absolutely affects driving safety. Due to the battery pack, EVs are significantly heavier than fuel-powered cars, making their shock absorbers more prone to issues. Once leakage starts, I noticed obvious vehicle wobbling on bumpy roads, longer braking distances, and unstable handling - it feels like riding a seesaw. Driving like this long-term may accelerate tire wear and even cause loss of control during turns. I recommend getting it checked immediately; don't try to save money by delaying repairs. Leakage usually results from aged seals or damaged oil seals - just replace the shock absorber at a professional repair shop, don't mess around with small garages. Pay more attention to shock absorber condition during routine maintenance to prevent many problems. While EVs are quiet and eco-friendly, never compromise on safety details.

What Causes Engine Shaking When Spark Plugs Get Wet?

Generally, spark plug issues can lead to poor engine performance, resulting in abnormal phenomena such as difficulty starting, unstable idle, poor acceleration, backfiring during sudden acceleration, excessive exhaust emissions, and increased fuel consumption. A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Spark plugs are installed on the side or top of the engine. In earlier designs, spark plugs were connected to the distributor via ignition cables. However, over the past decade or so, engines in passenger cars have largely transitioned to direct connection between ignition coils and spark plugs. Under high voltage, the air between the center electrode and side electrode of a spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. This creates a discharge channel between the gap, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body known as a "spark." Along with the heat and expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2,000 to 3,000°C, which is sufficient to ignite the air-fuel mixture in the engine's combustion chamber.

What do C and H on the dashboard represent?

The CH on the dashboard represents the water temperature gauge. The water temperature ranges from C to H. C stands for 60 degrees Celsius. Once the needle of the water temperature gauge reaches C, it indicates that the water temperature has reached 60 degrees. The red H mark represents a temperature of 110 degrees Celsius. The span from 60 to 110 degrees Celsius allows for an estimation of the temperature indicated by the water temperature gauge. Introduction to the water temperature gauge: Automobile water temperature gauges generally use a scale from 60 degrees Celsius to 120 degrees Celsius or are labeled with Cold (C) to Hot (H). The water temperature indicator light is used to show the temperature of the coolant inside the engine. Some indicators use colors to display different statuses: blue indicates the water temperature is too low, red indicates the water temperature is too high, and no light indicates normal operation. When a car engine is running, the combustion of gasoline generates significant heat, with some being expelled through the exhaust pipe and some transferring to the engine block. If the engine block temperature becomes too high, it can cause thermal expansion of components and lead to damage. Therefore, water is used for circulating cooling. Hazards of excessively high or low water temperature: Hazards of low water temperature: It can cause incomplete combustion of the air-fuel mixture, reduce power output, increase fuel consumption, lead to poor lubrication, and result in excessive emissions. Hazards of high water temperature: Normally, when the water temperature is within the normal range, the needle will point to the middle position of the water temperature gauge (this may vary between different car models; it is recommended to check the warranty manual). However, there is usually a red zone on the right side of the water temperature gauge indicating the high-temperature range. When the needle approaches this zone, caution is required as it indicates the water temperature is too high. If no action is taken and driving continues, it can easily lead to the radiator boiling over.

What is the issue when the Volkswagen Bora displays EPC?

The reasons why the Volkswagen Bora displays EPC are: the throttle is dirty and needs cleaning, the brake light is not working and requires checking the brake switch and wiring, fuel quality issues, engine stalling due to improper operation, and intake system faults such as leaks or blockages. When the EPC indicator light comes on, it is important to promptly visit a 4S shop or a professional auto repair shop to have a technician read the fault codes with a computer and determine the issue for targeted repairs. EPC (Electronic Power Control) stands for Engine Electronic Power Control System. When a sensor fails or detects an abnormal condition, the control system will take corresponding measures based on preset programs. Below is a detailed introduction to other situations that may cause the EPC light to come on: Engine intake system fault: When the engine intake is not smooth or the intake volume is insufficient, the EPC light will prompt. Throttle fault: Carbon buildup is a common fault in the throttle. Additionally, dirt on the main body can also affect intake, causing the indicator light to come on. Fuel system fault: For example, issues such as substandard fuel, fuel deterioration, or poor fuel atomization. Engine fault: Insufficient engine pressure or problems with the power system such as the intake valve can also trigger the EPC light. ECU control unit fault: For example, interference with the vehicle computer signals or false alarms from the vehicle computer. Brake light fault: If the brake light is not working, the brake switch is faulty, or the brake wiring is faulty. Solutions for when the car's EPC indicator light comes on: Troubleshoot the intake system, use fuel with the appropriate octane rating, clean the throttle, etc. Remove carbon deposits from related parts. Re-flash the ECU-related data. If the EPC indicator light comes on, the owner can first try turning off the engine and restarting it to see if the EPC light remains on. If it does not come on again, there may be no issue, possibly just the EPC indicator being affected. If the EPC indicator light remains on or frequently comes on, the vehicle should be driven to the nearest repair point for professional assistance in troubleshooting to eliminate potential safety hazards. The full English name of EPC is: Electronic-Power-Control, which translates directly to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system mainly includes controllers and sensors related to the power system. When the sensor data in the system is abnormal, the EPC system will take some measures on the power system based on preset programs. Common EPC indicator lights generally display two colors: yellow and red. The EPC fault light is yellow, and if the car can still drive normally, proceed slowly to a repair point for inspection. If the EPC fault light is red, it indicates a more serious situation, and the vehicle should be pulled over immediately to contact relevant repair personnel for maintenance. Forcing the vehicle to drive may directly affect the core components of the car or driving safety.
