The reason why the car fan keeps running after the engine is turned off is: after the car is parked, the engine temperature remains high. When the engine stops, the water pump also stops, causing local temperatures to continue rising. To prevent excessive temperatures from damaging the engine, the fan continues to operate after the engine is turned off to cool it down. Engine classifications: 1. According to the working method of the intake system, they can be divided into naturally aspirated, turbocharged, mechanically supercharged, and twin-charged; 2. According to the piston movement method, they can be divided into reciprocating piston internal combustion engines and rotary piston engines; 3. According to cylinder arrangement, they are classified as inline engines, V-type engines, V-type engines, and horizontally opposed engines.

Why does the car electric fan not rotate?

Water temperature not reaching the requirement, relay failure, or thermostat switch issues. Below are the related explanations about the car electric fan not rotating: 1. Water temperature not reaching the requirement: Nowadays, most car radiator fans operate using electronic temperature control. Therefore, the fan will only start rotating normally when the internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not rotate. 2. Relay failure: If the water temperature meets the requirement but the car radiator fan still does not work, the issue might be with the fan's relay. If the relay fails, the car's radiator fan will not function. 3. Thermostat switch issues: Check the thermostat switch, as faults in this component can sometimes affect the operation of the car radiator fan. Therefore, it is also important to inspect this part.

What to Do If No Contract Is Provided When Buying a Car?

Not providing a contract when buying a car is a wrongful act. The customer can directly request it, and if the seller refuses, the customer can demand the termination of the contract or consult relevant legal authorities. Below is relevant information about car purchase contracts: 1. Introduction: A car purchase contract is a formal sales agreement signed between the buyer and the dealer, serving as a basis to protect the rights and interests of both parties. 2. Key Points to Note: When signing the car purchase contract, clearly specify the brand of the car, vehicle identification number, engine number, vehicle code (chassis number), and other essential elements of the car itself. Pay special attention to including both the vehicle code and identification number to prevent the dealer from swapping the car. Also, specify the main configurations, color (down to the seat color), whether it's manual or automatic transmission, and the documents to be delivered with the car. The price should clearly state the total transaction amount (either the ex-factory price or the on-the-road price), payment method, and deadline.

Which Land Rover model has 7 seats?

Land Rover 7-seater models include Range Rover Sport, Defender, Range Rover Evoque, Range Rover Velar, and Discovery Sport. Here is more relevant information: 1. Defender: The Land Rover Defender is a mid-to-large SUV, regarded by many as an off-road marvel. However, the latest Defender no longer features a traditional ladder frame, which might require some acceptance. Replacing the ladder frame is a chassis that is three times stronger and significantly lighter in weight. The move away from a body-on-frame design is actually a technological advancement that should be embraced. The new powertrain delivers more robust performance, while the upgraded configurations and materials offer a more luxurious experience, showcasing what a modern vehicle should embody. 2. Range Rover Evoque: Similar to the Velar, the Range Rover Evoque gains its appeal through its stylish design, attracting a wide range of male and female consumers. The Evoque has a relatively lower body height, which enhances its visual appeal. The interior exudes a sense of elegance and homely comfort, with an abundance of functional systems that provide a luxurious experience. However, its climbing capability is not as strong as some other mid-sized SUVs, but this is not a significant drawback.
