How to Tell if Car Scratches Are Man-Made

What is the reason for the engine light on the dashboard?

The reasons for the engine light appearing on the dashboard are: 1. Sensor issues; 2. Maintenance problems; 3. Fuel quality issues; 4. Poor combustion of the air-fuel mixture; 5. Spark plug carbon buildup; 6. Engine knocking; 7. Oxygen sensor failure; 8. Coolant temperature sensor damage. Methods to address the engine light on the dashboard: 1. Observe the engine self-check light; 2. Pay attention to whether the engine coolant temperature is too high; 3. Check if the engine is low on oil; 4. Observe if the engine is running smoothly; 5. If any of the above conditions exist, it is necessary to visit the nearest auto repair shop for maintenance.

What is the general voltage of a car battery?

A car battery is generally 12 volts. The working principle of a car battery is: during charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted into electrical energy. When the battery discharges, metallic lead is the negative electrode, which is oxidized into lead sulfate; lead dioxide is the positive electrode, which is reduced into lead sulfate. When the battery is charged with direct current, lead and lead dioxide are produced at the two electrodes respectively. After the power is cut off, it will return to the pre-discharge state and form a chemical battery. Methods for maintaining a car battery include: 1. Regularly clean the battery; 2. Reduce electricity usage when the engine is off; 3. Replace the battery periodically; 4. Start the car regularly.

Is It Safe to Sleep in a Car with the Heater On?

It is not safe to sleep in a car with the heater on. When the heater is running, the air circulation is usually set to internal recirculation mode. Sleeping in the car for an extended period can lead to dizziness, nausea, and even vomiting due to oxygen deprivation, as well as carbon monoxide poisoning. Here are some precautions to take when using the heater: 1. Leave a small gap in the window to allow air exchange between the inside and outside of the car; 2. Turn on the external air circulation mode when using the heater to promote air exchange; 3. Regularly check the vehicle's exhaust system for leaks to prevent exhaust fumes from entering the cabin and avoid poisoning; 4. Always turn off the engine and open the windows when resting in the car; 5. The optimal temperature inside the car is 22 degrees Celsius; 6. Be mindful of dryness when using the heater.

What Causes the Abnormal Noise at 70 to 80 km/h?

The cause is bearing failure. Below are common abnormal noises in cars: 1. Transmission noise: If the car makes abnormal noises while idling, and the noise disappears when the clutch is pressed, it indicates that the noise originates from a transmission malfunction. Transmission noises are generally caused by bearing or gear wear. 2. Steering wheel noise: If abnormal noises occur when turning the steering wheel left or right, it is due to a malfunction in the steering gear. Additionally, oil leakage from the steering gear dust cover, insufficient tightness or aging of the power belt can also cause abnormal noises. 3. Suspension noise: The suspension system operates continuously while driving, and the rubber bushings between the shock absorbers and various links will inevitably wear out. When the bushings age or fall off, abnormal noises will occur.

What are the differences between the Mercedes-Benz C180 and C260?

The differences between the Mercedes-Benz C260 and C180 mainly lie in body dimensions, driving methods, and the types of engines they are equipped with. 1. Different body dimensions: The C260 measures 4784mm in length, 1810mm in width, and 1457mm in height; the C180 measures 4783mm in length, 1810mm in width, and 1442mm in height. 2. Different driving methods: The C260 features front-engine, all-wheel drive (AWD); the C180 has front-engine, rear-wheel drive (RWD). 3. Different engines: The C260 is equipped with a 1.6T turbocharged engine; the C180 comes with a 1.5T turbocharged engine. Below is additional information: Differences between front-engine, all-wheel drive (AWD) and front-engine, rear-wheel drive (RWD): AWD vehicles combine the advantages of front-wheel and rear-wheel drive and are commonly used in performance and off-road vehicles. With power delivered to all four wheels, they offer superior road passability, acceleration, and off-road capability compared to front-wheel or rear-wheel drive vehicles. However, they consume more fuel and are more expensive. RWD vehicles, where the rear wheels push the car forward, are typically found in higher-end sports sedans. The front-mounted engine requires a driveshaft to transmit power to the rear wheels, resulting in a more balanced weight distribution than front-wheel drive vehicles. This setup provides stronger acceleration, better handling, and improved stability. However, the more complex drivetrain increases cost and weight, leading to higher prices and fuel consumption compared to front-wheel drive vehicles. Power loss is also greater, and the rear passenger compartment may have a raised floor due to the driveshaft, reducing space. Traction is generally lower than in front-wheel drive vehicles. Differences between 1.6T and 1.5T turbocharged engines: The main difference is displacement. The 1.5T has a 1.5-liter displacement, while the 1.6T has a 1.6-liter displacement. The 'T' stands for turbocharged engine. Turbocharging increases the engine's air intake, allowing more complete combustion of fuel in the cylinders, thereby boosting output power. Generally, higher values indicate stronger power. Compared to naturally aspirated engines of the same displacement, turbocharged engines offer greater power output and higher environmental efficiency.
