What Causes Loud Idling Noise in Cars?

How severe must wheel rim damage be to render it unusable?

Assess the degree of wheel rim deformation and fracture. If the wheel rim is dented or cracked, place the tire on a balancing machine for testing. If the tire exhibits bouncing phenomena, it should no longer be used. Below are relevant details: 1. Impact severity: Minor impacts to the wheel rim generally don't significantly affect the suspension. For more severe collisions, visit a repair shop for inspection, including four-wheel alignment checks. 2. Hitting curbs: Collisions with curbs can affect the tire, wheel rim, suspension, and shock absorbers. Severe impacts may damage the tire, causing sidewall bulges, blowouts, or wheel rim deformation. Suspension damage could lead to body deformation and abnormal noises during driving.

What Should You Pay Attention to When Driving at Night?

Precautions for night driving are as follows: 1. Pay attention to non-motor vehicles on the right side during encounters: When encountering oncoming vehicles at night, avoid panicking, repeatedly stepping on the brake pedal, or swerving to the right. Be mindful of pedestrians and bicycles on the right side. When the distance to the oncoming vehicle is 150 meters, switch from high beam to low beam. This is not only a courtesy but also ensures driving safety. If the oncoming vehicle does not switch to low beam, immediately reduce speed and use continuous switching between high and low beams to signal them. If the other party still does not change and the glare makes it difficult to see the road, pull over and stop—never retaliate by using high beams. 2. Control your speed: Traffic flow is lighter at night, and interference from pedestrians and bicycles is relatively less, making it easier for drivers to speed, which can lead to accidents. When transitioning from bright to dark areas, the eyes need time to adjust, so reduce speed accordingly. Be especially cautious when approaching curves, slopes, bridges, narrow roads, or areas with poor visibility, and be prepared to brake or stop at any time. When driving through bustling streets, neon lights and other illumination can affect visibility, so maintain a low speed. In adverse weather conditions like rain, snow, or fog, drive slowly and carefully. 3. Increase following distance: At night, drivers have limited visibility and often encounter dangerous or emergency situations. Therefore, always be ready to stop. To avoid collisions, increase the following distance appropriately. 4. Avoid overtaking when possible: Before overtaking, check if there are obstacles on the right side of the vehicle being overtaken to prevent it from swerving left to avoid obstacles and causing a collision. If overtaking is necessary, first use continuous high-low beam signals to alert the vehicle ahead. Only proceed with overtaking after confirming it is safe. 5. Combat driving fatigue: Night driving, especially after midnight, is most prone to fatigue and drowsiness. Additionally, the lack of roadside scenery reduces stimulation for drivers, increasing the likelihood of fatigue. Frequently switching between high and low beams can help alert other vehicles and alleviate visual fatigue. If too tired, pull over to rest instead of forcing yourself to drive through the night. 6. Accurately judge road conditions: Generally, if the vehicle slows down automatically and the engine sound becomes muffled, it indicates increased resistance, suggesting the car is climbing a slope or driving on soft ground. If the vehicle speeds up automatically and the engine sound becomes lighter, resistance has decreased, indicating a downhill slope. On moonless nights, the road appears gray-black, while areas beyond the road are pitch black. Puddles appear brighter, while depressions look darker. Experienced drivers follow the rule of "staying on gray, avoiding black." Also, learn to judge terrain changes based on headlight beam variations—shorter beams may indicate curves or uphill roads, longer beams may suggest downhill slopes, and gaps in the beam could mean potholes. 7. Prepare emergency lights: Besides standard items like spare tires, jacks, and wrenches, carry lighting equipment such as emergency lights and warning signs for sudden stops. In case of a breakdown, these can help create a safe zone around your vehicle.

Who Should Own the Vehicle After a Total Loss?

Right-hand drive (RHD) vehicles refer to cars with the steering wheel installed on the right side of the cabin. Below is relevant information about RHD vehicles: Countries with RHD vehicles: Over thirty countries and regions use RHD vehicles, including Hong Kong, Singapore, Japan, New Zealand, the UK, Australia, Ireland, Indonesia, India, Thailand, Pakistan, Fiji, Tonga, Papua New Guinea, Malta, Sri Lanka, Nauru, Jamaica, Malaysia, and South Africa. Most RHD countries are members of the Commonwealth or regions that adopted similar configurations. Precautions for RHD vehicles: Structurally, RHD vehicles are identical to left-hand drive (LHD) vehicles, except for the reversed orientation. Manual transmission gear patterns remain the same, but automatic transmissions differ—for instance, gear locks may be present, and buttons might be relocated to the right side. Pay attention to the gear lever.

How many times does a car need to be inspected annually after 10 years?

For cars over 10 years old, an annual inspection is required. For vehicles over 15 years old, inspections are required every six months. The documents needed for the annual vehicle inspection include: the vehicle's registration certificate, valid compulsory insurance policy, the owner's ID card, and all traffic violation records must be cleared in advance. According to the relevant provisions of the "Regulations for the Implementation of the Road Traffic Safety Law," the following are the details: 1. Passenger transport vehicles: Within 5 years, inspect once a year; for those over 5 years, inspect every 6 months. 2. Trucks and large or medium-sized non-passenger transport vehicles: Within 10 years, inspect once a year; for those over 10 years, inspect every 6 months. 3. Small and mini non-passenger transport vehicles: Within 6 years, inspect once every 2 years; for those over 6 years, inspect once a year; for those over 15 years, inspect every 6 months.

How far can a car go on the last bar of fuel?

Each vehicle has a different fuel tank capacity, and typically when only one bar of fuel remains, it can still travel over 100 kilometers. Here is some relevant information about fuel tank maintenance: 1. Regularly clean the fuel system: The fuel tank provides waterproofing and insulation. If the car idles for long periods, the fuel system should be cleaned or the filter replaced at 30,000 kilometers. Otherwise, the fuel system may become clogged, increasing the tank's air pressure. This can cause the car to shake while driving. Due to the high pressure, the fuel tank is prone to cracking, and in severe cases, fuel leakage may occur, increasing fuel consumption. 2. Tighten the fuel cap: In summer, temperatures are high, and fuel and water evaporate quickly. Make sure to tighten the fuel cap to prevent fuel line leaks. Also, regularly check the water level in the radiator, the oil level in the crankcase, the brake fluid level in the master cylinder, and the electrolyte density and level in the battery. If any of these levels fall below the normal range, remember to add or adjust them promptly.
