The solutions for carbon deposit issues in sedans are: 1. Add fuel additives appropriately; 2. Clean the throttle valve regularly; 3. Reduce prolonged idling; 4. Avoid using low-quality gasoline. The causes of carbon deposits in sedans are: incomplete combustion of fuel in the engine, where the paraffin and gum substances in gasoline that cannot be fully burned remain in components such as the fuel injector, throttle valve, fuel lines, and spark plugs, forming deposits under high temperatures. The hazards of excessive carbon deposits include: 1. Affecting the air intake, leading to reduced power; 2. Preventing gasoline from fully atomizing, resulting in incomplete combustion; 3. Causing engine knocking.

Does the dash cam consume power when parked?

The parking monitoring function of a dash cam does not consume much power, as it is not continuously active 24/7. In most cases, the dash cam remains in standby mode. It only automatically turns on and enters recording mode when the vehicle's sensors detect vibrations caused by external impacts. After recording for no more than 15 seconds, it returns to sleep mode. Therefore, the parking monitoring feature does not significantly drain the battery. Additionally, under normal circumstances, parking monitoring requires the use of a voltage reduction cable, which includes low-voltage protection to ensure continuous parking monitoring without depleting the battery. Both time-lapse recording and parking monitoring can serve the purpose of vehicle surveillance, but comparatively, time-lapse recording consumes more power. Time-lapse recording is a photographic technique that compresses long recording times into shorter clips. The main principle is to convert lengthy videos into shorter, fast-motion clips, similar to the fast-forward playback function in movies, transforming a long video segment into a brief one. Parking monitoring only activates video recording when the vehicle's sensors detect vibrations, and after recording for no more than 15 minutes, it returns to sleep mode. When no vibrations are detected, it remains in standby mode. In other words, parking monitoring does not provide 24/7 surveillance, so it naturally does not consume as much power as continuous recording.

Is it necessary to register the lift modification for off-road vehicles?

Lift modifications for off-road vehicles require registration. There is a basic principle for vehicle modifications: as long as the modifications do not affect driving safety, they are not prohibited and can pass the annual inspection. The prerequisite is to report the modifications in advance. Not all vehicle modifications fall under the category of illegal modifications. According to the "Motor Vehicle Registration Regulations," the following five types of modifications can be legalized: First type: Small and micro passenger vehicles can install front and rear anti-collision devices, but the installed devices cannot be modified into other materials, must not obscure the vehicle license plate, and must not have external protrusions. Second type: Cargo vehicles can install windshields, water tanks, toolboxes, spare tire racks, etc. Third type: Interior decorations can be added, but they must not obstruct the driver's view. Fourth type: Roof racks can be installed, but they must not exceed one-third of the vehicle's length. Fifth type: If the vehicle's body color is changed, the owner must visit the vehicle management office within ten days to register the change. Currently, only paint changes are recognized; vinyl wraps will not be approved for color change registration.

Is It Normal to Have Sludge on Shock Absorbers?

It depends on whether there is oil leakage. Shock absorbers will experience wear during vehicle operation. Severe wear can lead to oil seepage or leakage. If there is only oil seepage, it will not cause the shock absorber to fail or reduce the comfort and stability of the vehicle's ride. However, it is still necessary to continue monitoring to prevent excessive oil seepage or more severe oil leakage. Below is relevant information: The Function of Shock Absorbers: Automotive shock absorbers are connected between the wheel chassis and the vehicle body frame, absorbing vibrations when the vehicle bumps and providing stability during cornering. The Hazards of Shock Absorber Oil Leakage: Oil leakage in automotive shock absorbers indicates damage, and the shock absorption effect will gradually decrease. Over time, if the oil inside the shock absorber leaks completely, it will lose its shock absorption function. Therefore, leaking shock absorbers need to be replaced promptly. Symptoms of Shock Absorber Oil Leakage: As long as the internal oil of the shock absorber leaks and decreases, it will affect its damping force for vibration filtration. The main symptoms noticeable in the driver's compartment are softened vehicle suspension and even issues like looseness and abnormal noises. On larger pothole roads, the shock absorber is also highly likely to be damaged due to bottoming out.

What is the difference between manual-automatic transmission and AT?

Manual-automatic transmission and AT differ as follows: 1. Manual-automatic transmission: This is an added feature designed to enhance the fuel efficiency and controllability of automatic transmissions, allowing drivers to regain control over shift timing that was originally determined by the computer. In situations like urban traffic jams, drivers can still use the automatic mode for ease. Manual-automatic transmission combines the advantages of both automatic and manual transmissions, integrating manual gear shifting with automatic gear shifting. 2. AT: This is a type of transmission structure that does not require a clutch for shifting. It has fewer gears but greater variation, ensuring smooth connection and easy operation, providing convenience for the driver and comfort for passengers.

What is the minimum ground clearance of a car?

Minimum ground clearance refers to the distance between the lowest protruding part of a vehicle's chassis and the level ground when the vehicle is fully loaded (with the maximum allowable load mass). It reflects the vehicle's ability to pass over obstacles or uneven terrain without collision. Specific characteristics are as follows: The greater the minimum ground clearance, the stronger the vehicle's ability to pass over obstacles or uneven terrain, but the higher the center of gravity, which reduces stability; the smaller the minimum ground clearance, the weaker the vehicle's ability to pass over obstacles or uneven terrain, but the lower the center of gravity, which can increase stability. Passenger cars generally travel on flat urban roads, so they have smaller ground clearance, while off-road vehicles have larger minimum ground clearance to overcome larger obstacles.
