What is the working principle of hybrid electric vehicles?

The working principle of hybrid electric vehicles is: the vehicle is powered by both the internal combustion engine and the electric motor to drive the car. Characteristics of hybrid electric vehicles: high fuel economy performance, superior driving performance. During startup and acceleration, due to the assistance of the electric motor, fuel consumption can be reduced. The maintenance methods for hybrid electric vehicles are: 1. Timely replacement of engine oil, oil filter, air filter, and fuel filter; 2. Regular inspection of the vehicle body and tire replacement; 3. Periodic inspection of the braking system; 4. Regular check of chassis damage; 5. Use of high-quality fuel; 6. Reduction of prolonged idling situations.

Do Hybrid Vehicles Need to Be Charged?

Hybrid vehicles do not need to be charged. Taking a series hybrid electric vehicle as an example, the working principle is as follows: 1. At the beginning of the vehicle's operation, the battery is in a fully charged state, and its energy output can meet the vehicle's requirements, so the auxiliary power system does not need to work; 2. When the battery level drops below 60%, the auxiliary power system starts. When the vehicle's energy demand is high, the auxiliary power system and the battery pack simultaneously provide energy to the drive system; 3. When the vehicle's energy demand is low, the auxiliary power system not only provides energy to the drive system but also charges the battery pack; 4. Due to the presence of the battery pack, the engine operates under relatively stable conditions, thereby improving emissions.

How to Start and Park an Automatic Car?

To start an automatic car: 1. Without pressing the foot brake, press the start button twice to initiate the car's computer system self-check, which should last at least 6 seconds; 2. Press the foot brake and then the start/stop button to ignite the engine; 3. Release the foot brake and let the car warm up in place; 4. Press the foot brake, release the handbrake, and shift the gear from P to D; 5. Slowly release the foot brake to start moving; 6. Depending on road conditions, gently press the accelerator to increase speed. To park an automatic car: 1. Press the brake to slow down until the car stops; 2. Once stopped, shift to N gear; 3. Tighten the handbrake; 4. Release the foot brake and ensure the car is stationary; 5. Press the foot brake again and shift to P gear; 6. Turn off the engine.

What lights should be used when driving a motor vehicle at night?

Different situations require the use of different lights when driving a motor vehicle at night: 1. Use low beams correctly when following a vehicle closely in the same direction; 2. Alternate between high and low beams correctly when passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signals; 3. Switch to low beams correctly when meeting an oncoming vehicle at a distance of more than 150 meters; 4. Use low beams correctly when turning at an intersection; 5. Alternate between high and low beams correctly to alert the vehicle being overtaken when passing; 6. Use low beams correctly when driving on well-lit roads with streetlights; 7. Use high beams correctly when driving on unlit roads at speeds exceeding 30 kilometers per hour.

How many kilometers can you drive when the fuel gauge light comes on?

The fuel gauge light indicates that you can still drive for 30 to 50 kilometers. The function of the fuel gauge is to display the fuel level in the car's fuel tank. The fuel gauge consists of a voltage regulator, a fuel indicator, and a fuel level sensor. The low fuel level warning device is designed to illuminate immediately when the fuel in the tank falls below a specified level, alerting the driver to take action. Precautions for using the car fuel gauge include: 1. Do not wait until the warning light comes on to refuel; insufficient fuel level is detrimental to the normal operation of the fuel pump and reduces its service life. 2. Display deviation: When replacing the battery or fuel filter and restarting the vehicle, the fuel gauge pointer may show a lower position than before. This is due to the release of pressure after opening the fuel tank, causing the fuel level to drop. This display deviation is a normal phenomenon.
