How many kilometers should a car run for maintenance?

What are the types of vehicle braking devices classified by braking force source?

Vehicle braking devices can be classified into pneumatic and hydraulic types based on the braking force source. Below are detailed introductions to these two types of vehicle braking systems: 1. Pneumatic: Pneumatic braking uses a brake pedal to control an air valve for braking force regulation. During braking, the air pressure from the air reservoir to each brake cylinder is controlled by the pedal travel. The air pressure in the brake lines activates the brake cylinders, which in turn operate the brakes. Pneumatic braking typically employs drum brakes and is more suitable for heavy-duty vehicles. 2. Hydraulic: During braking, the brake pedal directly drives the master cylinder to generate pressure, which is transmitted to each brake cylinder through hydraulic lines. To reduce the required operating force, most systems are equipped with a booster. Hydraulic brakes commonly use disc brakes.

What do the lights on the dashboard indicate after the engine starts?

One scenario is when the light illuminates for 2 seconds and then turns off during engine startup, which is part of the vehicle's circuit system self-check function. The other situation is when a warning light remains on after the self-check, indicating a fault in a certain electronic control system. Dashboard indicator light descriptions: 1. Battery indicator: Displays the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts. If it doesn't illuminate or stays on continuously, the generator and circuit should be checked immediately. 2. Fuel indicator: Warns of low fuel. When this light comes on, it means the fuel is nearly depleted. Generally, the vehicle can still travel about 50 kilometers after this light appears. 3. Washer fluid indicator: Shows the level of windshield washer fluid. If the fluid is nearly empty, this light will illuminate to remind the owner to refill. The light turns off after adding cleaning fluid. 4. Electronic throttle indicator: Commonly seen in Volkswagen models. During vehicle self-check, the EPC light will illuminate for a few seconds and then turn off. If there's a fault, this light stays on, and maintenance should be performed promptly. 5. Front/rear fog light indicators: These lights show the working status of front and rear fog lights. Both lights illuminate when fog lights are activated. 6. Turn signal indicators: When turn signals are activated, the corresponding light flashes at a certain frequency. When the hazard warning lights are pressed, both lights illuminate simultaneously. The indicators automatically turn off after the turn signals stop. 7. Seatbelt indicator: Shows seatbelt status. Depending on the vehicle model, the light may illuminate for several seconds as a reminder or stay on until the seatbelt is fastened. Some vehicles may also have an audible alert.

What does 'heat' mean in new energy vehicles?

heat refers to heating. In vehicles, this switch is used for defogging. When the switch is turned on, the exterior rearview mirrors and rear windshield will be heated, primarily to prevent frost formation, defrost, or defog, making it easier for the driver to observe the outside conditions. Below is a detailed introduction to new energy vehicles: 1. Overview: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. 2. Others: New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, hydrogen engine vehicles, etc. Pure electric vehicles are vehicles that use a single battery as the energy storage power source.

Should I repaint the scratches on my new car door?

The decision to repaint depends on the severity of the scratches. Here are specific recommendations regarding repainting: 1. Minor damage: It's unavoidable that some hard objects may scratch the car paint during daily use. For such minor damage, besides passive acceptance, you can take preventive measures. Applying wax every 1-2 months or installing wear-resistant patches on frequently affected areas can help prevent minor scratches to some extent. 2. Light damage: In most cases, the scratches on the paint surface are clearly visible. For this situation, it's recommended to use a touch-up pen for treatment. 3. Moderate damage: When the paint shows obvious peeling, exposing the primer, immediate action is necessary. Repainting should be done as soon as possible to prevent the exposed steel plate from rusting due to rain or other factors.

How Many Kilometers Can an Electric Vehicle Travel on 1 kWh of Electricity?

Under normal circumstances, 1 kWh of electricity can power a vehicle for approximately 7 kilometers. However, this figure is heavily influenced by the vehicle's curb weight and road conditions, making it less significant as a reference. Below are specific factors affecting the driving range: 1. Comprehensive Factors: The increase in an electric vehicle's range is the result of multiple factors. To enhance its driving range, the key lies in battery technology—continuously improving battery performance—while also considering factors such as vehicle size and price. 2. Other Factors: The overall driving range can be affected by various other elements, including battery performance in high and low temperatures, optimization of battery BMS technology, upgrades to the vehicle's energy recovery system, lightweight body design, and energy-saving technologies in hardware. External driving conditions, air resistance coefficient, mechanical transmission efficiency, vehicle weight, and the number of passengers can all impact the actual driving range of an electric vehicle.
