Can You Wipe a Dirty Car with a Wet Cloth?

What Are the Basic Knowledge of Car Circuit Repair?

Automotive circuits generally consist of power supply circuits, starting circuits, ignition circuits, lighting and signal device circuits, instrument information system circuits, etc. Power supply circuit: Also known as the charging circuit, it is composed of the battery, generator, regulator, and charging indicator device. Power distribution and circuit protection devices can also be included in this circuit. Starting circuit: This circuit consists of the starter, starting relay, starting switch, and starting protection circuit. Devices for preheating during cold starts and their control circuits can also be included in this circuit. Ignition circuit: This is a circuit unique to gasoline engine vehicles. It consists of the ignition coil, distributor, electronic ignition controller, spark plugs, and ignition switch. Electronically controlled ignition systems managed by microcomputers are generally categorized under the engine electronic control system. Lighting and signal device circuit: This circuit includes headlights, fog lights, marker lights, turn signals, brake lights, reverse lights, interior lights, and related control relays and switches. Instrument information system circuit: This circuit consists of instruments and their sensors, various warning indicators, and controllers.

What are the reasons for an electric vehicle suddenly losing power and becoming immobile?

The reasons for an electric vehicle suddenly losing power are as follows: 1. GPS: Power loss caused by wiring during GPS installation. It is recommended to have the GPS inspected at the installation location. 2. Anti-theft device: Incorrect wiring or poor grounding of the anti-theft device. It is advised to check the wiring of the anti-theft device. 3. Battery depletion: Forgetting to turn off lights or other electrical equipment after leaving the vehicle, leading to battery depletion. Replacing the battery or temporarily charging it can resolve the issue. Repeated battery depletion will reduce the battery's lifespan. 4. Fuse box: Issues with the fuse box itself or the connection between the fuse box and the wiring harness plug. The main causes may be poor contact between the fuse box socket pins and the internal circuit of the fuse box or loose spring clips on the wiring harness plug. It is recommended to inspect the fuse box and fuses, replacing the fuses if necessary.

What Causes the Generator Fault Light to Illuminate?

The reasons for the engine fault light illuminating include poor mixture combustion, sensor issues, and fuel quality problems. Here are the explanations for the causes of engine problems: 1. Engine Misfire: An engine misfire refers to a situation where one cylinder in a multi-cylinder engine stops working, leading to symptoms such as abnormal shaking and lack of acceleration. Professional inspection and repair are required. 2. Engine Overheating: After prolonged or aggressive driving, the engine temperature may exceed normal levels, causing the engine fault light to illuminate. In this case, simply stop the car and allow it to cool down naturally. 3. Severe Engine Carbon Buildup: Severe carbon buildup in the engine can result in issues like poor acceleration and increased fuel consumption. It is necessary to clean the engine promptly in such cases. 4. Poor Fuel Quality: Low-quality fuel can disrupt the normal operation of the engine. In such situations, it is advisable to switch to higher-quality fuel.

What Are the Effects of Water Damage on a Vehicle?

After a vehicle is submerged in water, the exhaust pipe is prone to taking in water, which can lead to severe consequences such as water entering the engine. Here are methods for identifying flood-damaged and accident vehicles: 1. Inspect the car locks: Check for signs of forced entry, tampering, or adhesive injection. Then, use the key to open each door to see if all locks are from the same set and if they turn smoothly. Note that if turning the key is very difficult or nearly breaks the key before the door opens, it might be due to water damage causing rust in the central control motor, leading to poor performance. 2. Engine compartment: Examine the mounting brackets for the compartment's lighting and signal lights for breaks or looseness. Inspect wire connectors and sockets; if they contain a lot of mud or show rust spots, the vehicle may have been submerged. 3. Engine compartment evaluation: Check the wiring and vacuum hoses on the engine block, as well as the gaps between the high-voltage ignition coils and spark plugs for mud traces. Assess whether the aging and cracking of hoses and wires match the vehicle's age, and check the security of the fuel injector mounts. Rust on springs can also help determine the likelihood of water damage.

How Much Harm Does Radiation from New Energy Vehicles Cause to the Body?

Currently, the radiation from most new energy vehicles poses minimal harm to the body, with levels not even reaching one-tenth of the standard limits. In fact, these radiation values are even lower than those from everyday mobile phone use, so there's no need to worry about radiation from electric vehicles. The safety standards for electromagnetic wave radiation and electromagnetic fields are clearly defined by the World Health Organization (WHO): the safe standard for electric field radiation is 5000V/m, and for magnetic field radiation, it's 100μT. China's environmental evaluation standards also set a limit of 100μT, and radiation levels below this threshold are harmless to the human body.

What is NEDC fuel consumption?

NEDC fuel consumption is called constant-speed fuel consumption. Here are specific details about constant-speed fuel consumption: 1. Significance: Constant-speed fuel consumption refers to the fuel economy indicator when a car is driving at a constant speed on good road surfaces. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. For example, France and Germany use the constant-speed fuel consumption at 90Km/h and 120Km/h as the main evaluation indicators for fuel economy. 2. Calculation method: Fuel consumption per 100 kilometers/100 * limit * 0.8.
