What is the reason for the fan continuing to run after parking?

The reason for the fan continuing to run after parking is that the engine coolant temperature at the moment of parking is higher than the acceptable soaking temperature of the engine. The vehicle's computer automatically calculates the fan's operating speed and duration to control the fan's operation. The higher the engine temperature, the longer the fan runs after parking. When the engine coolant temperature drops below the soaking temperature, the fan turns off to protect the engine and extend its service life. If the fan continues to run after the engine temperature has already dropped, it may be due to a loose electrical connection. In this case, you can try disconnecting the fan's wiring harness to cut off power separately. The function of the car fan is to increase the airflow speed through the radiator core, enhance cooling efficiency, and accelerate water cooling. The fans used in car engines are classified into axial-flow fans and centrifugal fans based on their structural principles, and into mechanically driven and electrically driven based on their driving methods. The working principle of the car cooling fan is based on electromagnetic induction. It uses a Hall sensor component as a synchronous detection device to control a set of circuits, switch the energizing sequence of the windings, generate a rotating magnetic field, and achieve electromechanical integration for electronic commutation. The cooling fan is installed between the engine and the radiator. When the fan blades rotate driven by the engine, they generate high-speed airflow to carry away the heat from the coolant in the radiator, thereby achieving the purpose of cooling the engine.

How Can Beginners Drive on the Road?

Tips for beginners driving on the road: 1. Stay calm: First, adjust your psychological state. Faced with fast-moving traffic and complex roads, don’t get overly nervous—remember to keep a cool head. Beginners often panic, unsure how to shift gears or turn, and may feel like lifting the car when other vehicles pass by. In reality, driving calmly according to the rules will ensure no issues. 2. Have a companion: It’s best for beginners to have someone accompany them. A friend who can drive sitting beside you acts as a reassurance; any mistakes made while driving can be promptly pointed out and corrected. 3. Be prepared: Before hitting the road, mentally review driving essentials and familiarize yourself with the brake, accelerator, and clutch to avoid stepping on the accelerator instead of the brake when nervous. Also, get comfortable with each gear, as beginners often forget to shift up or down when tense. The roaring sound of the engine is frequently ignored by novices, and driving a manual car like an automatic is a common mistake. Therefore, mastering these basic operations before driving is crucial.

How to Check for Frame Deformation?

Remove the frame and lay it flat. Stretch a steel wire through the centers of the front and rear crossbeams of the frame, then cross the wires between adjacent beams. The difference in distance from the two intersection points to the centerline should not exceed 3mm. Use a plumb line, straightedge, and square to check its straightness and verticality. Below are related introductions: 1. Definition of the frame: The frame, also known as the chassis, is the base of the vehicle. It generally consists of two longitudinal beams and several crossbeams, supported by the suspension system, front axle, and rear axle on the wheels. It must have sufficient strength and rigidity to withstand the vehicle's load and impacts transmitted from the wheels. 2. Judging the quality of the frame: To assess the design and structure of the frame, it is essential to first understand the various forces the frame must endure while the vehicle is in motion. If the frame lacks toughness in any aspect, even the best suspension system cannot achieve good handling performance.

How Many Minutes to Warm Up the Car?

The correct way to warm up your car is to start driving within 30 seconds to one minute after ignition. However, avoid driving at high RPMs during this time. Keep the speed low and limit the engine RPM to no more than 3000–3500, ideally around 2000 RPM. Driving aggressively at this stage can cause irreversible damage to the engine and transmission due to excessive wear. Once the engine reaches its normal operating temperature, you can resume your usual driving style. The reasons for warming up the car are as follows: 1. Lack of Lubrication: After prolonged parking, the engine oil flows back into the oil pan at the bottom of the engine. When you start the engine after a long period of inactivity (e.g., overnight), the upper part of the engine lacks lubrication as it is temporarily without oil. 2. Inefficient Fuel Vaporization: Before the engine reaches its operating temperature (approximately between 90–110 degrees Celsius), the fuel system cannot effectively vaporize gasoline due to the low temperature. 3. Transmission Gear Lubrication: This is the aspect most people are unaware of and often overlook. Similar to engine oil, transmission gear oil flows to the lower part of the transmission when the car is cold. Only when the car is in motion does the gear movement circulate the oil to lubricate the upper parts.

What is the fuel consumption of the Beidouxing?

The Suzuki Beidouxing has a fuel consumption of approximately 7.0 liters per 100 kilometers, making it a relatively fuel-efficient vehicle. Some drivers have even reported achieving less than 6 liters per 100 kilometers. Below is some relevant information about the Beidouxing: 1. Engine: The Suzuki Beidouxing is equipped with a 1.4-liter naturally aspirated engine across all models. This engine delivers a maximum power of 71 kW and a maximum torque of 120 Nm, with the maximum power achieved at 6,000 rpm and the maximum torque at 3,600 rpm. The engine features VVT technology and multi-point fuel injection, and it utilizes an aluminum alloy cylinder head and block. Paired with this engine is a 5-speed manual transmission. Manual transmissions are known for their reliability and durability, and they also have lower maintenance costs. 2. Body Dimensions: The Suzuki Beidouxing uses a MacPherson independent suspension at the front and a non-independent single longitudinal swing arm suspension at the rear.

What is the bulb model for the BYD Qin headlights?

The bulb model for the BYD Qin headlights is H7. The illumination effect of the headlights directly affects nighttime driving operations and traffic safety. Therefore, traffic management authorities worldwide generally stipulate the lighting standards for automotive headlights in legal forms to ensure safe nighttime driving. More details are as follows: 1. Illumination distance requirements: To ensure driving safety, the driver must be able to identify any obstacles on the road within 100 meters in front of the vehicle. The illumination distance of the car's high beam must exceed 100 meters. This data is determined based on the vehicle's speed. With the increase in modern vehicle speeds, the required illumination distance may also increase. The illumination distance of the car's low beam is approximately 50 meters. The positioning requirements mainly involve illuminating the entire road surface within the illumination distance without deviating from the road. 2. Anti-glare devices: Automotive headlights should be equipped with anti-glare devices to prevent the driver of an oncoming vehicle from being dazzled during nighttime encounters, which could lead to traffic accidents. During nighttime encounters between two vehicles, the beam is tilted downward to illuminate the road within 50 meters in front of the vehicle, thereby avoiding dazzling the driver of the oncoming vehicle.

How to Solve the Home Charging Problem for New Energy Vehicles?

New energy vehicles can be directly charged at home with 220V. The following is an introduction to charging new energy vehicles: 1. Charging with a three-hole socket: Use a standard plug socket with a rated current not exceeding 16A to charge directly at home, which takes about 8-10 hours to fully charge. 2. Charging with an AC charging pile: Charge directly on the AC grid with higher current using a charging pile, which takes about 4 hours. The power of slow charging piles is usually 3.5kW and 7kW, and this value depends on the rated input power of the onboard charger. For single-phase AC charging, the rated input current of the onboard charger is currently divided into two mainstream types: 16A and 32A, resulting in 16*220≍3.5kW and 32*220≍7kW. 3. Charging with a DC charging pile: When connecting an electric vehicle to the AC grid or DC grid, a DC power supply device with control guidance function is used. Generally, only pure electric vehicles on the market are equipped with DC charging function, which is the so-called "fast charging". Fast charging takes a short time, as the high-power onboard DC charger directly outputs DC to charge the vehicle battery. The power of fast charging piles on the market ranges from 30kW to over 100kW, and the charging time also varies from a few minutes to 2 hours.
