What Causes the Whining Sound of the Engine at Low Speed?

Introduction to the causes of abnormal engine noise at low speed: 1. Engine noise: If the internal components of the car engine, such as pistons, valves, gears, and camshaft bearings, have excessive clearance or are damaged, intermittent or continuous "clanking" metal knocking sounds or irregular metal friction sounds may occur, indicating significant wear of engine parts. 2. Dashboard noise: Poor assembly craftsmanship by car manufacturers often leads to loose or unstable connections in areas such as door panels, glove compartments, air vents, and dashboard panels, resulting in friction. When driving on bumpy roads, vibrations can cause repeated rhythmic noises from internal loose parts, and sometimes a sudden "clunk" sound may occur. However, it does not affect the reliability or driving safety of the car. 3. Wheel noise: Rusty brake discs or trapped sand and dirt can produce sharp squealing sounds during braking. There's no need to panic, as the solution is simple—rust will wear off after running for a while, and sand or dirt can be cleaned manually with water. 4. Chassis noise: When encountering bumps, "thud" or "clicking" sounds may occur, mostly due to loose suspension shock absorbers or connecting components. This situation requires urgent attention as it can severely affect driving safety.

What to Do When a Car Radiator Leaks?

Solutions for a leaking car radiator: First, inspect the radiator. If the water pipe is cracked and the crack is not too large, you can try to fix it yourself. If you have a strong leak stopper, pour it into the radiator, then start the engine to circulate the coolant. The leak should stop in about ten minutes. Below are some maintenance tips for car radiators: 1. Keep the engine idling to continue dissipating heat, and open the engine hood to speed up heat dissipation. Do not attempt to continue driving if the water temperature is too high or the engine is overheating to avoid major engine damage. Do not try to open the radiator cap, as hot liquid may spray out and cause burns. Do not pour cold water onto the engine block or cylinder head, as this may cause the block to crack due to sudden cooling. 2. After some time, check if there is any leakage under the car. Wrap the radiator cap with a wet towel and slowly turn the first switch (about 1/4 turn). Once the steam pressure is released, fully open the radiator cap and check the water level and quality in the radiator, as well as whether the fan belt is abnormal. If the water level is low, slowly add water up to the maximum mark. 3. If the radiator is leaking or the fan belt is loose or broken, call a towing company and wait for rescue. If necessary, you can also drive the car to a service center at low speed after the engine has completely cooled down. Remember, do not drive at normal speed, as this may cause permanent damage to the engine.

Why must motor vehicles adhere to the principle of right-hand traffic?

Because it is explicitly stipulated in the "Road Traffic Safety Law." "Right-hand traffic" means that when motor vehicles and non-motor vehicles are driving on the road, if there is a centerline marked on the road, the centerline serves as the boundary; if there is no centerline, the geometric center serves as the boundary, determining left and right based on the direction faced—that is, the left side of the road is the left-hand lane, and the right side is the right-hand lane. Except for vehicles with special regulations, all must drive on the right-hand side of the road. Below are common traffic violations: 1. Running a red light: This is the most common violation. Since the new traffic regulations were introduced, running a red light results in a 6-point deduction. 2. Driving without a license: If a driver continues to drive while their license is suspended, they will be fined and detained for 15 days. Driving without a license or with a revoked license will result in 15 days of detention and a fine. 3. Overloading or overcrowding: For passenger vehicles exceeding the rated capacity by less than 20% or freight vehicles exceeding the rated load by less than 30%, a fine will be imposed. For passenger vehicles exceeding 20% or freight vehicles exceeding 30%, a fine will be imposed. 4. Drunk driving: Driving under the influence of alcohol will result in a 3-month suspension of the driver's license and a fine. Driving a commercial vehicle under the influence will also result in a 3-month suspension and a fine. 5. Speeding: If a vehicle exceeds the speed limit by 50%, the driver will be fined and have their license revoked.

How to Deal with Paint Scratches on a Car?

If it is general paint (alkyd enamel), it can be wiped off with thinner; if it is baked paint, mechanical methods are usually required for removal, such as using fine sandpaper for sanding first, followed by polishing; if it is water-based paint, simply wash it with car wash liquid. Below is a relevant introduction to automotive paint: 1. Function: Automotive paint is a protective film sprayed on cars, a type of coating that makes the car body less susceptible to corrosion. 2. Precautions: Refer to safety technical data before use; thoroughly stir the paint before use to ensure uniform color; always wear protective gear, including a respirator and work clothes when using it.

How to Replace the Battery in a Car Remote?

Press the button on the back of the remote to remove the key from the remote. Use a screwdriver to open the key latch and slide it open along the gap to remove the old battery, then replace it with a new one. Below is relevant information about car remotes: 1. Common car remote key malfunctions: Incorrect signal transmission; inability to control the door; door won't lock; key battery is dead. 2. Troubleshooting tips for a malfunctioning car remote: Hold down the unlock button on the remote key, insert the key into the ignition, quickly turn it to the car's self-check position, immediately turn it back to the lock position, and repeat this process rapidly three times. After removing the key, the remote should return to normal function.

What are the causes of refrigerant leakage in automotive compressors?

Here are the reasons for refrigerant leakage in automotive compressors: 1. Pipeline sealing: Corrosion of the condenser or evaporator; excessively high compressor temperature melting the pipeline seals at the connection points. 2. Inspection method: Add fluorescent dye along with the refrigerant. After driving the vehicle for a week, use a specialized UV lamp to inspect the air conditioning system. Any leakage points will glow, indicating component damage. If the car's AC compressor operates normally and provides cooling, with the compressor stopping and starting appropriately when reaching temperature, this indicates mild refrigerant shortage. If the car's AC blows hot air and the compressor runs continuously without stopping, this indicates severe refrigerant shortage in the system.
