What to do if the car is dented?

If the car is dented, you can take it to a repair shop for bodywork and painting. Below is relevant information about bodywork and painting: 1. Definition: Bodywork and painting is an automotive repair technique that involves restoring the deformed metal parts of a car's body. For example, if the car's outer shell has a dent, bodywork can restore it to its original shape, followed by spraying specialized paint to make the deformed metal surface look as good as new, matching the undamaged areas. 2. Operation: Common manual repair techniques for automotive bodywork include using various specialized tools to repair areas that are hard to reach with hand hammers, applying pressure to restore stretched and deformed parts, mastering cold and hot methods to straighten sheet metal and body correction, filling, and patching. It also includes repairing some non-metal components of the car.

What to Do If Gasoline Leaks into Engine Oil?

Check whether the spark plugs are firing normally, whether the engine is running smoothly, and whether there is any leakage in the car's fuel system. If any issues are found, promptly visit a 4S shop for professional assistance to drain the engine oil completely and perform a thorough cleaning. Gasoline entering the engine oil may be caused by the following reasons: 1. Incomplete combustion of gasoline: Unburned gasoline flows down the cylinder wall into the crankcase. In this case, check whether the spark plugs can fire normally and observe whether the engine operates smoothly. 2. Fuel system leakage: In this case, promptly inspect the fuel system to identify the source of the leak and carry out necessary repairs.

Should the handbrake be released or engaged after parking?

After parking, the handbrake should be engaged. Here are the specific details about the car handbrake: 1. Function: The handbrake, also known as an auxiliary brake, operates differently from the main brake. It uses a steel cable connected to the rear brake to apply braking force to the vehicle. 2. Long-term use hazards: Prolonged use of the handbrake can cause plastic deformation of the steel cable, which is irreversible and may reduce its effectiveness over time. 3. Operation process: When the handbrake is engaged, a hydraulic auxiliary cylinder is activated, pushing the main hydraulic cylinder beneath the vehicle, which in turn drives the air valve and brakes the drive shaft.

Should the Excelle use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the Excelle should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap. Typically, the 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 use 95 octane gasoline. However, with the application of some new technologies nowadays, the gasoline grade cannot be solely determined by the compression ratio. Engines with high compression ratios can also be tuned to use lower-octane 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 octane number, the higher the octane value 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 the Excelle occasionally uses the wrong gasoline grade, 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-octane gasoline, using higher-octane gasoline by mistake will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance in practice. For vehicles recommended to use higher-octane gasoline, using lower-octane gasoline can cause engine knocking. Due to the significantly lower octane value, the reduced ignition point may cause the gasoline to ignite prematurely during the compression stroke. If combustion occurs before the spark plug fires, resistance will be generated during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it may only increase noise without obvious damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear to pistons and cylinders, and in severe cases, even cylinder scoring.

What is the SVS fault and how to solve it?

SVS stands for engine fault. When the SVS indicator light is on, it indicates that the engine control unit has detected an error signal from a certain sensor or that the sensor has exceeded the usage standard. The solution for the SVS fault is: you can try to start the engine. If it fails to start, it might be due to an abnormal fuel pump. If it can still start, it could be a fault with another sensor, and replacing the corresponding sensor should resolve the issue. Reasons that may cause the car's SVS light to turn on include: 1. Poor engine combustion state; 2. Engine knocking; 3. Poor fuel quality; 4. Dirty engine cylinder interior with accumulated carbon deposits; 5. The electronic control unit cannot obtain engine data.
