What Are the Hazards of Oil Emulsification?

The hazards of oil emulsification: Oil emulsification will reduce various performance indicators of the oil, not only affecting the vehicle's power performance and fuel economy but also exacerbating engine wear. Over time, this can easily lead to bearing seizure and even complete engine failure. Causes of oil emulsification: 1. Cylinder liner damage: This is likely due to cracks in the cylinder liner, allowing coolant to seep directly into the oil pan through the cylinder wall. Alternatively, it could be due to aging of the cylinder liner sealing ring, necessitating a check of the seal. 2. Engine water plug leakage: If the engine water plug is severely aged, it will inevitably leak. In such cases, coolant can directly mix into the oil pan, making regular inspection of the water plug crucial. 3. Radiator damage: Additionally, if the oil cooler ducts are damaged, it can also cause oil to mix with water. 4. Cylinder head gasket damage: Due to the long-term high-pressure state of fuel in the cylinder, the cylinder liner may become damaged, causing the oil and coolant passages to interconnect, leading to oil emulsification.

How to Remove Small Yellow Spots on White Car Paint?

Causes and solutions for small yellow spots on car paint surface: 1. When parked outdoors, rainwater carrying iron particles falls on the car body. If not washed promptly, rust spots form on the paint surface. These rust spots can be cleaned using an iron particle remover. Spray it evenly on the yellow spots, then wipe with a car wash sponge or towel. If they don't come off, you can also use a detailing clay bar for polishing. 2. While driving, asphalt may splash onto the car paint. Asphalt's main component is hydrocarbons, a hydrophobic material insoluble in water but soluble in carbon disulfide. It's corrosive, and if not cleaned promptly, these yellow spots remain after the asphalt naturally wears off over time. For this, you can use a specialized tar remover for spraying and wiping. Tar remover is a powerful cleaner with some corrosive properties. Prolonged residue can damage the paint, so after using tar remover, rinse the car with clean water to avoid residue.

What Are the Possible Causes of Vehicle Pulling to One Side?

Possible causes of vehicle pulling to one side are as follows: 1. Unequal tire pressure on both sides. Unequal tire pressure can cause tires to become different in size, leading to vehicle pulling during rolling. 2. Deformation of front shock absorber springs with inconsistent cushioning on both sides. The condition of the shock absorber springs can be judged by pressing or comparing after removal. 3. Failure of front shock absorbers. After failure, the vehicle's suspension will be uneven in height during driving, resulting in uneven force distribution and causing the vehicle to pull to one side. 4. Poor return or incomplete separation of a wheel's brake. This is equivalent to applying partial braking on one side continuously, causing the vehicle to pull to one side during driving.

How to Check Rearview Mirrors When Changing Lanes at Night?

Judge the distance between vehicles based on the size and intensity of the headlights from the following car reflected in the rearview mirror. The closer the car is, the brighter the headlights will appear. Lane-changing techniques: 1. Always use turn signals before changing lanes: When changing lanes at night, activate the turn signal in advance to alert other vehicles. 2. Observe vehicles ahead and to the side/rear: Check the traffic conditions around your car via the rearview mirror to ensure it is safe before proceeding. While observing the rearview mirror, also check for any vehicles in the blind spots on both sides of your car. Once confirmed safe, prepare to change lanes. 3. Steer gently and change lanes swiftly: Avoid turning the steering wheel too quickly when changing lanes, as rapid steering at high speeds may increase the risk of rollover. Do not hesitate when changing lanes; proceed immediately once safety is confirmed. 4. Change lanes early to avoid obstacles: If encountering an obstacle ahead, change lanes in advance to prevent interference from vehicles in adjacent lanes, which could lead to braking or forced lane changes causing collisions.

What does 'sport' displayed on the car mean?

sport refers to the sport mode, which is used to increase power output and deliver higher torque. Here are the detailed explanations: 1. The sport mode is more effective when climbing slopes or overtaking. It can also be used during high-speed driving. Additionally, the high engine speed in sport mode helps to remove carbon deposits from the engine. 2. When the car is in sport mode, the electronic control unit increases the engine speed, ensuring the vehicle maintains sufficient torque for quick acceleration and deceleration. This allows the car's performance to be fully showcased, and the previously unexperienced 'pushing-back sensation' will be immediately noticeable.

What maintenance should be done when a car reaches 20,000 kilometers?

At the 20,000-kilometer mark, the primary maintenance tasks for a car include changing the engine oil, replacing the air filter, replacing the cabin air filter, and replacing the oil filter, among others. The focus is on replacing wear-prone components and fluids such as power steering fluid, as well as checking the remaining lifespan of certain parts. Here are the details: 1. Vehicle maintenance mainly involves replacing wear-prone components and fluids. 2. Wear-prone components of a car include brake pads, tires, wiper blades, brake discs, various filters, spark plugs, ignition coils, etc. 3. The fluids in a car include engine oil, transmission fluid, coolant, brake fluid, and power steering fluid, among others. 4. During car maintenance, it is recommended that owners check the moisture content of the brake fluid. Since brake fluid is highly prone to absorbing water, if the moisture content exceeds 3%, it should be replaced immediately. 5. Additionally, the remaining lifespan of wear-prone components should also be inspected. Tires, in particular, are made of rubber. Over time, tires will age, typically requiring replacement every four years. However, for frequent drivers, it is advisable to shorten the replacement cycle.
