What are the symptoms of a bad front wheel bearing in a car?

Where are the fog lights on the Atenza?

The fog lights on the Atenza are installed at the front and rear of the vehicle, serving to illuminate the road and provide safety warnings during rainy or foggy weather conditions, thereby enhancing visibility for both the driver and surrounding traffic participants. Due to low visibility in foggy conditions, which restricts the driver's line of sight, these lights help increase the operational distance. Fog lights are categorized into front fog lights and rear fog lights, with the front fog lights typically being bright yellow and the rear fog lights red. The Atenza is a flagship model of the new generation mid-to-high-end sports sedan, developed and manufactured based on Mazda's spirit of breaking conventions and starting from scratch. In terms of exterior design, the Atenza adopts Mazda's new KODO design language, featuring a U-shaped front face and LED headlights, with LED daytime running lights integrated into the headlight assembly of the new model.

Can New Cars Meeting China IV Emission Standards Be Licensed?

Cars meeting China IV emission standards cannot be licensed, but those already licensed can still be used. After the implementation of the 'China V' standard, 'China IV' vehicles can still be driven on the road, and used cars can be transferred locally or sold to other regions, but not to key areas designated by the state for air pollution prevention and control. Starting from April 1, 2016, in 11 provinces and cities (Beijing, Tianjin, Hebei, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong, Guangdong, and Hainan), all imported, sold, and registered light-duty gasoline vehicles, light-duty diesel passenger vehicles, and heavy-duty diesel vehicles (only for public transport, sanitation, and postal purposes) must comply with the 'China V' standard. In other regions of the country, starting from January 1, 2017, all manufactured, imported, sold, and registered light-duty gasoline vehicles and heavy-duty diesel vehicles (for passenger and public transport, sanitation, and postal purposes) must comply with the 'China V' standard; starting from January 1, 2018, light-duty diesel vehicles must comply with the 'China V' standard.

Which city does the license plate 'Liao H' belong to?

Liao H is the license plate code for Yingkou City in Liaoning Province. Other license plate codes in Liaoning Province are as follows: Liao A for Shenyang City, Liao B for Dalian City, Liao C for Anshan City, Liao D for Fushun City, Liao E for Benxi City, Liao F for Dandong City, Liao G for Jinzhou City, Liao J for Fuxin City, Liao K for Liaoyang City, Liao L for Panjin City, Liao M for Tieling City, Liao N for Chaoyang City, Liao P for Huludao City. License plate composition: 1. The first character of the license plate is a Chinese character, representing the provincial-level administrative region where the vehicle is registered, which is the abbreviation of provinces, municipalities, and autonomous regions; 2. The second character is an English letter, representing the prefecture-level administrative region where the vehicle is registered, which is the letter code for prefecture-level cities, regions, autonomous prefectures, and leagues, generally ranked by the provincial vehicle management office based on the administrative divisions of each region.

Why is there a ticking sound after the car is turned off?

Generally, the reasons for abnormal sounds after the car is turned off are as follows: 1. Uneven cooling of the engine. After driving for a period of time, the engine temperature is high. When turned off, the temperature of various components decreases, and thermal expansion and contraction are not uniform, causing friction between metal parts inside the engine due to cooling contraction, resulting in abnormal sounds. 2. Turbo cooling sound. Under normal circumstances, the exhaust gas temperature reaches 600-700°C, accelerating the temperature generated by the rapid rotation and friction of the turbo. After turning off, thermal expansion and contraction are also very noticeable, leading to abnormal sounds. 3. Exhaust pipe cooling sound. Typically, the exhaust pipe temperature during cold idle is around 200 degrees. When the car is under high load or there is a mixture burning in the exhaust pipe, the temperature will be even higher. Therefore, the exhaust pipe also undergoes thermal expansion and contraction, producing abnormal sounds, often originating from the front end of the exhaust pipe and the flexible connection area.

What are the domestic wheel hub brands?

Domestic wheel hub brands include CITIC Dicastal, Wanfeng Auto, Lizhong, Zhongnan Aluminum, and Ronal. The wheel hub is the rotating part of the tire's inner rim connected to the wheel center via spokes, which is the metal component mounted on the axle that supports the tire. The function of the wheel hub is to bear the rigid rotational inertia between the car and the tire and to provide braking force. Currently, the commonly used wheel hubs in automobiles are divided into steel wheel hubs and alloy wheel hubs. Wheel hubs on the market can be categorized into steel wheel hubs and alloy wheel hubs based on material. The main advantages of steel wheel hubs are their simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. The disadvantages are their unattractive appearance, heavy weight, and susceptibility to rust. Aluminum alloy wheel hubs are primarily made of aluminum with appropriate additions of metals such as manganese, magnesium, chromium, and titanium. Compared to steel wheel hubs, they are lighter in weight, have better heat dissipation, and can extend tire life. Magnesium alloy is an alloy based on magnesium with the addition of other elements. Its characteristics include low density, high specific strength, large specific elastic modulus, good heat dissipation, excellent vibration damping, greater ability to withstand impact loads than aluminum alloy, minimal deformation at high speeds, low inertial resistance, which helps improve the car's straight-line driving performance, reduces tire rolling resistance, and consequently decreases fuel consumption.

Engine Malfunction Light On but Driving Normally with Vibration?

The engine malfunction light is on, accompanied by vehicle vibration, primarily due to poor combustion of the air-fuel mixture. Incomplete combustion can lead to carbon buildup in the engine, which is the most significant cause of vehicle vibration. Additionally, when the oxygen sensor detects and reports this poor combustion to the ECU, the malfunction light is triggered as a warning. Hence, the simultaneous occurrence of the engine malfunction light and vehicle vibration. Issues such as faulty spark plugs, defective ignition coils, malfunctioning fuel pumps, or clogged fuel lines can all contribute to poor combustion of the air-fuel mixture in the engine. If the engine malfunction light is on, follow these steps: First, check if the engine is running normally—look for signs like vibration, black smoke emission, or difficulty starting. If any of these symptoms are present, avoid restarting the engine. Note: Never restart the engine if the red warning light is illuminated. If the engine operates normally and the vehicle can be driven, proceed to a service station as soon as possible to diagnose the issue. Service technicians can easily retrieve trouble codes using a portable diagnostic tool, enabling targeted repairs based on the specific fault information. If the engine runs normally, the owner may also attempt to gently reconnect all wiring harness connectors, as a loose connection could be the culprit. Alternatively, repeatedly turning the key to the ON position might reset the system and clear the light.
