What to Do If Your Car Is Exposed to the Sun?

You can protect your car from the sun in the following three ways: 1. Park in the shade whenever possible: Try to park your car in a shaded area, such as a parking lot under cover. 2. Ventilate the interior: When it's safe to do so, leave a 1-2 cm gap in each of the four windows to allow air circulation inside the car. This helps effectively disperse harmful gases and regulate the interior temperature. 3. Use sunshades: These can effectively protect the car's interior from sunlight and UV damage. The drawbacks of prolonged sun exposure include: 1. Paint fading and aging; 2. Interior deformation; 3. Release of harmful gases; 4. Reduced sealing performance; 5. Increased safety hazards inside the car; 6. Tire damage; 7. Risk of vehicle self-ignition.

Why are the registration date and issuance date on the vehicle license different?

The vehicle license displays two dates: the registration date and the issuance date. Sometimes these dates are the same, while other times they differ. This discrepancy can indicate whether the vehicle has been transferred. The motor vehicle license is the legal document permitting a vehicle to operate on roads within China. It consists of a cover, a main page, and a supplementary page. The front of the main page contains the endorsed certificate core, while the back features a photo of the vehicle, all sealed in a plastic cover. The supplementary page is also an endorsed certificate core. When a new vehicle is registered, the license is produced, and at this time, the registration date and issuance date are the same. If the vehicle undergoes a transfer procedure, the license is reissued, and the issuance date will change accordingly. Similarly, if the license is lost and reissued, the issuance date will also be updated. Vehicle transfers require the reissuance of the vehicle license, so each transfer involves a new vehicle inspection and the issuance of a new license. The number of vehicle transfers cannot be determined from the license itself. For this information, one should refer to the vehicle registration certificate, which typically does not require reprinting but only records the transfer date on the details page during each transfer.

What Causes Car Door Leakage?

Car door leakage can be caused by the following reasons: The door seal is not tight enough, leading to water leakage; the drainage outlet at the bottom of the door is blocked, preventing water from draining; or the waterproof membrane inside the door is damaged, causing water to flow directly onto the door sill trim and then onto the floor mat. Additional information: 1. For the issue of a loose door seal: Check if the seal is severely damaged or deformed and replace it as soon as possible. If the seal is intact, adjust the door inward slightly to ensure a tighter contact between the seal and the door, reducing the chance of water leakage. 2. For a blocked door drainage outlet: Remove the strip at the bottom of the door to reveal a square drainage outlet. If the car hasn't been cleaned for a long time, debris and mud may accumulate. Use a flat-head screwdriver to clear the blockage, allowing water to drain properly. 3. For a damaged waterproof membrane inside the door: The solution is more complex. First, sprinkle some water on the window, then open the door to check for any signs of leakage.

Why is there an odor inside the car after replacing the three-way catalytic converter?

After installing a new three-way catalytic converter, you may notice a burnt smell. This is because the new catalytic converter has not yet undergone high-temperature heating. It is normal to experience a burnt odor initially after replacement. Once the converter heats up to a certain temperature and undergoes chemical reactions with exhaust gases, the burnt smell will gradually diminish, and you can use it without concern. Composition of the three-way catalytic converter: The three-way catalytic converter typically consists of four main components: the housing, vibration damping layer, substrate, and catalyst coating. Housing: Made of stainless steel to prevent oxidation and flaking, which could lead to substrate blockage. Vibration damping layer: Composed of gaskets or wire mesh pads, it serves to seal, insulate, and secure the substrate. To protect the substrate from damage due to vibration or thermal deformation, the gasket is made of expanded mica and aluminum silicate fibers, bonded with adhesive. Substrate: Constructed from honeycomb-shaped ceramic materials, though many are also made of metal (including stainless steel). Catalyst: Composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the substrate to form the purifying agent. Lifespan of the three-way catalytic converter: The typical lifespan of a three-way catalytic converter ranges between 80,000 to 100,000 kilometers. The actual lifespan depends on the vehicle's usage conditions, fuel quality, and driving environment.

What are the symptoms of a blown diesel engine head gasket?

Diesel engine head gasket failure exhibits the following phenomena: 1. Overheating: Main symptoms include loss of power during acceleration, misfiring sounds when accelerating with cylinder deficiency, small amounts of water discharge from the exhaust pipe. If oil-like liquid appears in the radiator, it indicates coolant passage failure; if water is found in engine oil, it indicates oil passage failure. 2. Gas leakage: High-pressure, high-temperature combustion gases escape through the head gasket, resulting in reduced engine power, stalling, or inability to maintain high speeds or full load. 3. Oil leakage: Lubricating oil leaks from the head gasket area, causing excessive oil consumption in the oil pan and potentially leading to engine crankshaft burning. 4. Coolant leakage: Cooling water leaks from the head gasket area, causing significant water consumption that may result in engine dry burning and cylinder deformation.

How Often Should a Motorcycle Sprocket Be Replaced?

When the teeth of the motorcycle sprocket become sharpened or the chain and teeth do not mesh well, it should be replaced. Functions of the Motorcycle Sprocket: 1. Energy Saving: When a sprocket is installed on a motorcycle, the driving sprocket, through the chain, drives the driven sprocket and the outer wheel, which then engages the inner sleeve via pawls to rotate the rear wheel and propel the motorcycle forward. 2. Reduced Resistance: When the throttle is closed, the rear wheel continues to move forward using the motorcycle's inertia, automatically disengaging from the sprocket and transmission system of the energy-saving sprocket, eliminating the resistance from the transmission system and engine that was passively dragged during inertial travel. Background of Motorcycle Sprockets: Currently, most motorcycle sprockets are of a one-piece structure, where the transmission gear disc and the wheel hub are connected and rotate together. When the engine is turned off, the motorcycle can only operate if placed in neutral, and it is not possible to coast by closing the throttle at any time, whether on flat ground or downhill. For motorcycles, due to their slower speed, this not only wastes fuel but also increases engine wear, reducing the engine's service life.
