"The fault code 0101 on Dongfeng Dolika indicates a lack of urea in the vehicle. This code serves as a reminder for the driver to refill the urea. To resolve this, open the urea filler cap and pour in the urea solution. Fault resolution method: When the vehicle is low on urea solution, a warning light resembling a fuel tank with 'Adblue' will illuminate on the dashboard (usually yellow or blue). The urea tank is typically located on the left or right side of the vehicle frame. Unscrew the cap on top of the urea tank to refill it. If the vehicle is not consuming urea, it may be due to a clogged urea nozzle or a system malfunction. The digital dashboard will display corresponding fault codes. In such cases, it is recommended to visit a service station for inspection and repair. Function of urea solution: It reduces nitrogen oxide compounds in vehicle exhaust, lowering pollution levels and helping the vehicle meet national emission standards. The SCR system's intelligent control prevents the vehicle from starting when the urea solution level is insufficient. To ensure normal operation, always maintain an adequate supply of urea solution. Vehicle urea solution is essential for heavy-duty diesel vehicles to meet China's National IV emission standards. It consists of a 32.5% urea concentration in ultrapure water, made from urea crystals and ultrapure water."

What Category Does a Generator Belong To?

Generators are mechanical devices that convert other forms of energy into electrical energy. Below is some relevant information about generators: 1. Working Principle: Generators are mainly composed of components such as the stator, rotor, end cover, brushes, frame, and bearings. (1) The stator consists of the frame, stator core, winding coils, and other structural parts that fix these components; (2) The rotor consists of the rotor core, rotor poles, slip rings, fan, and shaft; (3) The stator and rotor of the generator are connected and assembled through bearings, the frame, and end covers, allowing the rotor to rotate within the stator. By introducing a certain excitation current through the slip rings, the rotor becomes a rotating magnetic field. The stator coils then cut the magnetic lines of force, generating an induced electromotive force. This is then led out through the terminals and connected in a circuit, producing electric current. 2. Types: Depending on the form of primary energy used, different generators can be manufactured: (1) By utilizing water resources and working with turbines, hydroelectric generators can be made; (2) By using resources such as coal and oil, and working with boilers and steam turbines, steam turbine generators can be made; (3) By utilizing energy sources such as wind, nuclear, geothermal, and tidal power, various types of generators can be manufactured.

What is the Friction Coefficient of Brakes?

The friction coefficient of brakes refers to the ratio between the frictional force of two surfaces and the vertical force acting on one of the surfaces, specifically the ratio between the frictional force of the brake pads and brake discs and the force exerted by the wheel cylinder on the brake pads. Below is relevant information about brakes: 1. Drum Brakes: Two semi-circular brake shoes are installed inside the wheel hub, and the "lever principle" is used to push the brake shoes into contact with the inner surface of the hub, generating sufficient friction to reduce the wheel's rotational speed, thereby achieving braking. 2. Disc Brakes: A brake caliper controls two brake pads to clamp onto the brake rotor on the wheel. When the brake pads clamp the rotor, friction is generated between them to reduce the wheel's rotational speed, allowing the car to slow down or stop. 3. ABS Anti-lock Braking System: Most modern cars are equipped with an ABS anti-lock braking system, which ensures the car maintains directional control while braking without skidding or fishtailing. The principle of ABS is equivalent to manually creating intermittent braking, but this intermittent braking technology operates at a higher frequency and faster speed. Therefore, when a vehicle with ABS encounters an emergency, the brake must be pressed firmly and fully in one motion.

How often should the spark plugs of Volkswagen Touran be replaced?

Volkswagen Touran spark plugs need to be replaced every 25,000 kilometers or 18 months. If the spark plugs are not replaced for a long time, it may cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting the normal use of the vehicle. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine. It is recommended to follow the user manual. The following standards can be referenced for maintenance replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for external debris such as leaves or dust and ensure they are cleaned thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Install the removed high-voltage distributor wires in the order of ignition and secure the cover.

Why Does a Minivan Shake While Driving?

Here are the reasons why a minivan may shake while driving: 1. Severe engine carbon buildup: The most common cause of vehicle shaking is a dirty throttle body or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Solution: Clean the fuel system and check if the idle control valve has carbon buildup that needs cleaning. 2. Ignition system issues: Inspect the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also cause such symptoms. Solution: Check if the spark plugs have excessive carbon buildup and replace them if necessary. 3. Unstable fuel pressure: Have the fuel supply pressure and intake pressure sensors checked at a 4S shop. Abnormal fuel pump pressure or faulty intake pressure sensor readings can cause the vehicle to shake. Solution: Check the fuel pressure and replace components if needed. 4. Aging engine components: Vehicle shaking can also be related to worn engine mounts. Engine mounts act as the engine's shock absorption system, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and cabin, causing shaking at idle.

How often should a family car be inspected after 6 years?

Family cars should be inspected every 2 years after 6 years. The specific details are as follows: After the implementation of the new vehicle inspection regulations, cars between 6 and 10 years old must be inspected every 2 years. At the 6th and 8th year, the vehicle must undergo an on-site inspection. For private cars over 10 years old, the original inspection cycle still applies, i.e., once a year for cars between 10 and 15 years old, and once every 6 months for cars over 15 years old. During the vehicle inspection, the owner can apply for an inspection compliance mark at the local vehicle management office within 3 months before the expiration of the current inspection period. The vehicle inspection schedule is divided into the following categories (motor vehicles should be inspected from the date of registration): 1. Commercial passenger vehicles: Commercial passenger vehicles must be inspected once a year for the first 5 years; after 5 years, once every 6 months; 2. Trucks and large/medium non-commercial passenger vehicles: Trucks and large/medium non-commercial passenger vehicles must be inspected once a year for the first 10 years; after 10 years, once every 6 months; 3. Small and mini non-commercial passenger vehicles: Small and mini non-commercial passenger vehicles can be exempt from inspection twice within the first 6 years (but must apply for an inspection mark every 2 years); after 6 years, once a year; after 15 years, once every 6 months.
